PROBLEM TO BE SOLVED: To provide a cam device which is compact.SOLUTION: A cam includes: a rotator: a coupling member which performs the positioning of the rotator by connection of a first coupling part and a second coupling part disposed on the rotator; a stationary cam follower; and a groove cam which includes a groove, and causes the groove to rotate while the groove is engaged with the stationary cam follower and, thereby, moves. Therein, the groove cam moves to the coupling member side, pressurizes one side of the first coupling part and the second coupling part toward the other side, thereby, moves the one side and connects the one side with the other side. |
