A device for mounting a derailleur of a rear gearshift on a bicycle frame is provided. The device includes a pin suitable for being fixed in a corresponding seat of said bicycle frame, an annular seat formed on said pin, a support body of said derailleur, a through hole formed in said support body and crossed by said pin, an abutment element associated with said pin in said annular seat, wherein said abutment element provides a support in the axial direction on said pin. Said abutment element comprises a first and a second component, which are shaped like an annular sector and that can be connected together through respective shaped attachment portions.

To provide a clearance adjusting member that allows for easy attaching and detaching works and has no risk of falling off from a pin. A clearance adjusting member, in a pin coupling structure in which a first member and a second member are coupled freely to be rotated in relation to each other by a cylindrical pin, for adjusting an axial clearance between the first member and the second member, the clearance adjusting member comprises a shim in a U-shape or C-shape attached to the pin in the axial clearance, and a restricting means for restricting the shim so as to be freely releasable. A restricted piece protruding radially outward is formed on an outer circumferential edge of the shim. The restricting means includes a pair of restricting pieces spacedly arranged circumferentially on the radially outer side of the pin. One-side slanting piece extending by slanting to the direction of axial one-side towards a circumferential one-side is provided at a circumferential one-side end portion of one restricting piece. Another-side slanting piece extending by slanting to the direction of an axial one-side towards a circumferential another-side is provided at the circumferential another-side end portion of the restricting piece of another side. When the shim is inserted towards the axial clearance, the restricted piece pushes and rides over while elastically deforming the one-side slanting piece towards the circumferential one-side, or the restricted piece pushes and rides over while elastically deforming the another-side slanting piece towards the circumferential another-side, and thereby the restricted piece is positioned between the pair of restricting pieces and the shim is attached to the pin.

A fastening device for fastening at least two panels or flanges to each other is disclosed. The device comprises a male member, a female member and a washer. The male member is inserted into and at least partially through aligned slots in the panels or flanges. The male member includes or houses a first securing component. The female member defines an opening generally complementally shaped to the projection of the male member. The male member and the female member are configured to receive the at least two panels or flanges between them when the projection is received in the opening. The washer mates with the female member such that displacement of the washer relative to the female member towards the male member is substantially prevented. The device further comprises a second securing component configured to mate with the first securing component and to secure the washer against the female member.

A washer includes a first washer piece formed in a circular arc shape and formed with a first fitting portion that protrudes from one end in a circular arc direction; and a fourth washer piece formed with a second fitting portion that is recessed from one end in the circular arc direction and fitted with the first fitting portion. The first fitting portion and the second fitting portion are fitted in a state where approach and separation therebetween in the circular arc direction is controlled. One of the first fitting portion and the second fitting portion includes a crimped portion that is formed in a state where a side surface of the one of the fitting portions is pushed into a side surface of the other of the fitting portions, the one of the fitting portions being fixed to the other of the fitting portions by the crimped portion.

A securing element for axially securing a shaft or a component on a shaft includes at least two sector elements that can be joined to each other to form an essentially closed ring form with a central through opening for the shaft. The sector elements have latching structures or snap-fit structures, by which they can be connected to each other. The latching structures include a groove-like indentation with a first snap-fit hook formed in a first one of the sector elements and a spring arm with a second snap-fit hook arranged on a second one of the sector elements and engaging in the indentation in the first sector element.

The present disclosure relates to a formwork anchor receptacle for arrangement on a bearing element of a formwork element, having a receptacle element, which has a receptacle opening for insertion of an anchor rod and a ball section for mounting on the mounting element of the formwork element, and having a retaining apparatus for retaining the receptacle element on the bearing element of the formwork element, wherein the retaining apparatus has a spacer element for contacting the bearing element of the formwork element, wherein the spacer element has an mounting opening for mounting on the receptacle element and a formwork device having such a formwork anchor receptacle.

A fastening device for fastening at least two panels or flanges to each other is disclosed. The device comprises a male member, a female member and a washer. The male member is inserted into and at least partially through aligned slots in the panels or flanges. The male member includes or houses a first securing component. The female member defines an opening generally complementally shaped to the projection of the male member. The male member and the female member are configured to receive the at least two panels or flanges between them when the projection is received in the opening. The washer mates with the female member such that displacement of the washer relative to the female member towards the male member is substantially prevented. The device further comprises a second securing component configured to mate with the first securing component and to secure the washer against the female member.

According to an aspect of the present disclosure, a shim plate which is inserted between components that are assembled to and disassembled from one another via at least one shaft may be provided. The shim plate includes a plurality of plate pieces that are separable from one another, wherein the plurality of plate pieces are configured such that one plate piece is connected to the other plate piece in a circumferential direction, and an internal ring-shaped empty space is formed.

A washer includes a first washer piece formed in a circular arc shape and formed with a first fitting portion that protrudes from one end in a circular arc direction; and a fourth washer piece formed with a second fitting portion that is recessed from one end in the circular arc direction and fitted with the first fitting portion. The first fitting portion and the second fitting portion are fitted in a state where approach and separation therebetween in the circular arc direction is controlled. One of the first fitting portion and the second fitting portion includes a crimped portion that is formed in a state where a side surface of the one of the fitting portions is pushed into a side surface of the other of the fitting portions, the one of the fitting portions being fixed to the other of the fitting portions by the crimped portion.

A two-part washer for use with a cable gland is provided including a first partial annular part having a first end and a second end, and a second partial annular part having a first end and a second end, wherein the first end of the first part is adapted to interlock with the second end of the second part, wherein the second end of the first part is adapted to interlock with the first end of the second part, and wherein when the ends of the first and second parts are interlocked, an annular washer extending 360 degrees with an open interior is formed. A method of using the two-part washer to provide a watertight seal between a cable gland and a wall of an electrical enclosure is also provided.
