A press-fit connection between a high-strength component and a press-fit element is characterized by a non-circular previously made hole into which the press-fit element having a collar is inserted. Here, the collar is merely upset and pressed against a hole rim without embracing an underside of the component. Preferably, the hole rim is widened in a longitudinal direction such that a form-locking connection acting in opposition to the longitudinal direction is formed. The non-circular hole geometry is produced with the aid of a punch of circular cross sectional geometry, in that a cutter of the punch has leading and recessed cutting regions, with the result that disrupted partial regions are formed.

A pin having a tool engagement portion and a resiliently deformable cover arranged over the tool engagement portion. The resiliently deformable cover is operable to deform from a first position to a second position to allow for the engagement of the tool engagement portion with a tool. The tool engagement portion is substantially concealed when the cover is in the first position, reducing the opportunities for dirt ingress. A tool may be used to deform the cover and allow the tool to engage with the tool engagement portion such that rotation of the tool causes co-rotation of the pin.

An occurrence of thermal distortion when heterogenous materials are joined together is suppressed. Provided is a joining structure that includes a first member, a second member, a rivet and a resin-filled portion. The first member is formed of a first material. The second member is formed of a second material that is different from the first material. The rivet penetrates through at least the first member and joins the first member and second member together. The resin-filled portion is provided around the rivet at a side of the first member at which the second member is disposed. The resin-filled portion is formed by at least one of the first member and the second member and forms a gap between the first member and the second member. A resin member is disposed inside the resin-filled portion.

A fastener adapted to be installed in a hole of a composite structure includes a sleeve, a pin member, and a locking member. The sleeve has an outer surface having an outer diameter. The outer surface of the sleeve is textured. The outer diameter of the tubular portion is less than an inner diameter of the hole of the structure. The pin member has a shank portion. The sleeve is adapted to expand radially over the shank portion of the pin member to form an interference fit between the outer surface of the sleeve and the hole of the structure so as to provide an installed position of the fastener. When the fastener is in the installed position, the texture of the outer surface of the tubular portion deforms to engage with voids of the composite material present on the inner surface of the hole.

A fixture includes two mounted portions and an interposing portion. At least the one mounted portion includes a strut portion, a check portion, and an abutment portion. The strut portion is insertable into a mounting hole provided in a mounting target. The check portion is caught on the mounting target on an outlet side of the mounting hole. The abutment portion abuts on the mounting target on an inlet side of the mounting hole. When any one of the mounting target or the fixture vibrates, the check portion and the abutment portion deform to suppress a vibration in a direction parallel to an insertion direction. When any one of the mounting target or the fixture vibrates, the interposing portion deforms to suppress a vibration in a direction parallel to a plane orthogonal to the insertion direction.

A tether has a pair of guide plates. The pair of guide plates has two sides. A distance between points located on the two sides increases, as the points on the two sides approach a tip of the tether. The tether may have elastic branches. The pair of guide plates may have protrusions protruding toward an anchor. The tether may be made long by curving a tether intermediate portion. The tether may have a second guide plate and a third guide plate. When a pillar garnish is moved in a direction away from a pillar, the two sides of the guide plates are brought into contact with a rim portion of a tether housing portion defining the tether inserting aperture, thereby preventing the tether from rotating about a center axis line of the clip and the anchor to pass through the tether inserting aperture. When a bottom wall of the tether housing portion comes to a tether portion located between the guide plates and the anchor, the elastic branches and the protrusions prevent rotation of the tether. The second and third guide plates also prevent rotation of the tether.

A functional element for pressing into a workpiece comprises a functional section; and a fastening section having an abutment surface for introducing a press-in force into the functional element; a workpiece contact surface that is disposed opposite the abutment surface; and a sealing region for receiving displaced material of the workpiece, said sealing region being disposed between the workpiece contact surface and the functional section and forming a contact surface for the displaced material to seal a connection between the functional element and the workpiece, wherein the contact surface has a first part surface, which extends obliquely to an axial direction and which converges viewed in a press-in direction of the functional element, and a second part surface that adjoins the first part surface, that extends obliquely to the axial direction of the functional element, and that diverges viewed in the press-in direction of the functional element.

A mounting structure has: a first member in which a first through-hole is formed; a second member in which a second through-hole is formed; and a clip having a first shaft portion, a first anchor portion that is anchored on an edge portion of the first through-hole, a second shaft portion whose axial center is eccentric with respect to an axial center of the first shaft portion, and a second anchor portion that is anchored on an edge portion of the second through-hole, wherein a cross-sectional shape of a portion, which is disposed at an inner side of the first-through hole, of the first shaft portion is a polygonal shape, and a length along a longest diagonal line of the polygonal shape, or a length of a longest side of the polygonal shape, is longer than a minimum opening length of the first through-hole.

A pin joint assembly including: a first end lug and a second end lug; a pin hole extending through the first and second end lugs; a first retaining feature and a second retaining feature arrangeable at opposing ends of the pin hole; a headless pin including a pin body for inserting through the pin hole to rotatably couple the first and second end lugs, such that the pin body is retained between the first and second retaining features; a first bushing for positioning between the headless pin and the first end lug, and a second bushing for positioning between the headless pin and the second end lug; wherein the headless pin is isolated from the first and second retaining features.
