The end portion of a first member includes a plate part and a groove. The end portion of a second member includes an edge and two side surfaces. The groove extends around the edge of the second member and the two side surfaces. The groove includes a side surface including an engaging portion. One of the side surfaces of the end portion of the second member includes an engaged portion. A method for manufacturing a swaged structure includes preparing the first member including the plate part and the groove having a wide opening. The method further includes inserting the end portion of the second member into the groove after preparing the first member. The method further includes pressing the plate part in a direction narrowing the opening of the groove to bring the engaging portion into contact with the engaged portion after inserting the second member.

Systems and methods for an actuation system including a plurality of single actuation units for modular control of a tendon-driven robotic mechanism are disclosed.

A method of producing a seat reclining apparatus includes connecting one of a first connecting portion and a second connecting portion of a biasing member to associated one of a base member and a lock drive member, with a lock member and the lock drive member supported on the base member, thereby bringing the biasing member to a temporarily held state; mounting the ratchet to the base member so as to cover the biasing member in the temporarily held state; and fixing the other of the first connecting portion and the second connecting portion to the other of the base member and the lock drive member through an opening which is formed in one of the base member and the ratchet, thereby bringing the biasing member to the biasing state from the temporarily held state.

Couplers for a cable trough system including a terminal end sized to receive a terminal end of a trough member along a longitudinal direction of the body. A spring may be coupled to the body for securing the terminal end of the trough member to the coupler, the spring including first and second spring arms extending generally in opposition to one another in a plane generally parallel to the longitudinal direction. The spring may be received in a slot formed by the trough member. Also included may be a spring release mechanism coupled to the body, the spring release mechanism sliding in the longitudinal direction between a locked position, such that the first and second spring arms engage the terminal end of the trough, and an unlocked position, such that the first and second fingers release the first and second arms of the spring.

An axial section of a continuous portion where an outer peripheral surface of a spindle portion of a main spindle in which a punch is installed is continuous with an outer peripheral surface of a punch holder is formed of a first circular arc joined to the outer peripheral surface of the spindle portion and a second circular arc joined to the outer peripheral surface of the punch holder. The first circular arc and the second circular arc are in contact with each other. The second circular arc is smaller than the first circular arc in curvature radius.

A method for manufacturing a cap, which can insert a sheet member easily into a predetermined position of an upper part inside a cap body, without causing deformation to the sheet member or the cap body. The sheet member does not separate when a container is brought to reduced pressure. An annular protruding portion protruding on a lower surface side is formed in an annular flat region of a sheet member of an inside plug. After or at the same time that the sheet member is inserted into and installed at a predetermined position within a cap body, the annular protruding portion is pressed axially toward a top panel wall and deformed so as to become close to a flat shape, to enlarge the outer diameter of the sheet member. The inside plug is thereby held to be inseparable from inside a skirt wall and to be axially movable.
