Damper

摘要

Provided is a damper configured so that a compact pedal unit can be obtained using the damper and so that the damper can be easily retrofitted to a pedal unit. A damper (1) comprises elements such as: a pair of cams (slide cam (4) and stationary cam (5)) which rotate relative to each other about the axis (O1) to cause the sloped cam surfaces (4132, 5211) thereof to make sliding contact with each other; a coiled spring (3) which presses the sloped cam surface (4132) of the slide cam (4) against the sloped cam surface (5211) of the stationary cam (5); a case (2); and a resin roller (8) which is fitted in a rotatable manner on the shaft (7A). The rotational motion of the slide cam (4) about the axis (O1) is restrained by the case (2), and as a result, the slide cam (4) rotates about the axis (O1) relative to the stationary cam (5) in association with the rotation of the case (2) about O1.

1. A damper for generating torque in a rotational direction about an axis, comprising:
a torque generation mechanism comprising a first member and a second member that rotate relative to each other in the rotational direction about the axis, to generate torque in the rotational direction about the axis; a case housing the torque generation mechanism; an outer peripheral surface of the case being provided with a projecting portion for receiving force in a direction of rotating the case in the rotational direction about the axis; the first member rotating relative to the second member in the rotational direction about the axis, associated with rotation of the case about the axis; and the projecting portion being a shaft mounted on the case so as to receive the force in the direction of rotating the case in the rotational direction about the axis.
