The clutch mechanism portion comprises a push rod. The push rod comprises a cam follower. A Belleville spring functions as a clutch spring. The cam surface and the cam follower are formed such that a lever ratio of the push lever at a pivot start position is larger than a lever ratio of the push lever at a pivot finish position. The Belleville spring is formed such that a force required to move the push lever at the pivot finish position is smaller than a force required to move to the push lever at the pivot start position.
