Claims

[Claims for Utility Model Registration] (1) A curved line formed on a rotating cam body that extends from one end in the forward rotational direction of the rotating cam body and protrudes outward when viewed from the center of rotation of the rotating cam body. a curved forward cam surface having a shape that gradually approaches the rotation center in the state, a flat tip portion that continues toward the reverse rotation direction of the rotating cam body at the one end of the curved forward cam surface, and this flat tip portion; a first cam portion formed on the rotary cam body and having a linear reverse cam surface that gradually approaches the rotation center in the reverse rotation direction of the rotary cam body; a cam body rotating tool stopper surface that is continuous with the terminal end portions of the curved forward cam surface and the linear reverse cam surface of the cam portion; a curved reverse cam surface having a curved shape that protrudes outward when viewed from the rotation center of the rotating cam body toward the rotation direction and gradually approaches the rotation center; It has a flat tip that continues in the forward rotation direction of the rotary cam body, and a straight forward cam surface that gradually approaches the rotation center from the shoulder of the flat tip in the forward rotation direction of the rotary cam body. a second cam portion; and a cam body rotating tool stopper surface formed on the rotating cam body and continuous with the terminal end portions of the curved reverse cam surface and the linear forward cam surface of the second cam portion. and one of which is in sliding contact with the first cam portion and the second cam portion and is biased to move toward the rotation center of the rotary cam body, one of which is in contact with the curved forward cam surface of the first cam portion. A cam comprising: a pair of cam body rotating tools arranged such that the other is located at one end of the curved opposite cam surface of the second cam part. (2) The cam according to claim 1, wherein each of the pair of cam body rotators is a free roller.
