Abstract
Radius increased areas, radius decreased areas, and rotation stop areas are arranged in peripheral surfaces of first and second cams. In a state in which a portion in the peripheral surface of the first cam to which the first cam follower is contacting is positioned at an upstream end portion of the radius increased area, θ1 is a rotation amount of the first cam from the end portion needed until the first cam follower contacts the rotation stop area, and in a state in which a portion in the peripheral surface of the second cam to which the second cam follower is contacting is positioned at an upstream end portion of the radius increased area, θ2 is a rotation amount of the second cam from the end portion needed until the second cam follower contacts the rotation stop area. θ1<θ2 is satisfied.
