<p>A recessed portion (50) recessed in directions separated from a pin (30) is formed in at least one of a portion (20a) of a cam (20) opposing a first end portion (31a) of the pin (30) in directions orthogonal to a shaft center (P1) at the first end portion (31a) of the pin (30) and a portion (40a) of a pin support (40) opposing a second end portion (32a) of the pin (30) in directions orthogonal to a shaft center (P2) at the second end portion (32a) of the pin (30). With this, burrs (60) occurring on the pin (30) enter the recessed portion (50), and can be inhibited from catching a member in which the recessed portion (50) is formed. As a result, the burrs (60) can be inhibited from affecting the motion of the pin (30).</p> |
