Abstract: A cam device includes a drive cam, a follower, a holding cam, and a restriction roller. The drive cam reciprocally rotates. The follower intermittently reciprocate linearly by the drive cam. The holding cam is rotationally driven integrally with the drive cam. The restriction roller is provided on the follower and restricts a movement of the follower by coming in contact with the holding cam. The holding cam separates from the restriction roller and the holding cam is in a holding release state, when the drive cam is in an engaged state with the follower.
