Abstract
A rotation transmission mechanism of the invention includes an inner rotating member and an outer rotating member that is rotatably disposed with respect to the inner rotating member. The inner rotating member includes an outer peripheral protruding portion that protrudes toward an outer peripheral side. The outer rotating member includes an annular portion and an inner peripheral protruding portion. The outer peripheral protruding portion has a forward movement surface at a position shifted from a center of the outer peripheral protruding portion in a forward rotational direction in which the rotation transmission mechanism is rotated by forward movement. An elastically deformable portion is disposed between the forward movement surface and the inner peripheral protruding portion. The outer peripheral protruding portion and the annular portion are provided with guide portions that guide the outer peripheral protruding portion so as to slidably move in a rotational direction of the rotation transmission mechanism with respect to the annular portion.
