Claims

[Scope of utility model registration request]

(1) In a cam mechanism in which a driven member moves in accordance with the shape of the rim of the force t as the cam rotates, the rim of the cam is applied to the driven member in cooperation with the driven member. A cam mechanism consisting of a clamping mechanism guide for clamping.

(2) the clamping mechanism is pivotally supported by the driven member;
an arm whose tip faces an inner wall surface of the rim portion of the cam;
A device that is provided between the arm and the driven member and presses the driven member with its tip against the outer wall surface of the cam C rim portion, and the arm with its tip pressed against the inner wall surface of the rim portion of the military cam. The cam mechanism according to claim 1, which comprises a spring member that applies a rotational force of p.

(3) The cam mechanism according to claim 2, wherein the driven member and the arm are each provided with a roller that moves on the rim portion of the cam at the distal end side.
