Abstract:
1. A friction clutch comprising: a first member and a second member opposed to each other in an axial direction of a rotation shaft, the first member and the second member configured to be relatively movable in the axial direction of the rotation shaft and to change in a relative position in a rotation direction thereof; a friction plate provided between the first member and the second member and configured to be relatively rotatable with respect to the first member and the second member; a spring configured to press one of the first member and the second member toward the other of the first member and the second member in the axial direction of the rotation shaft to engage the first member and the second member with the friction plate; a first cam portion and a second cam portion provided on the first member and the second member, respectively, and configured to come into contact with each other such that a force in the axial direction of the rotation shaft is generated between the first member and the second member when the relative position of the first member and the second member changes in the rotation direction; and a damper member configured to damp a collision between the first cam portion and the second cam portion when the relative position of the first member and the second member changes in the rotation direction; wherein the first cam portion and the second cam portion are not in contact with each other until the damper member contracts by a predetermined dimension, and directly come into contact with each other when the damper member contracts by the predetermined dimension; and a position of the damper member is shifted in the axial direction from positions of the first cam portion and the second cam portion.
