Claims

[Scope of utility model registration request]

A clevis pin perpendicular to the axis of the cylinder is attached to the piston side in order to convert the linear motion of the piston, which reciprocates while sliding against the inner wall of the cylinder, into the rotational motion of a drive shaft provided with a yoke using a Scotch choke mechanism. In the row reactuator in which the yoke is provided with an engaging yoke groove, the yoke groove is connected to front and rear yoke members that sandwich the outer peripheral surface of the clevis pin in the cylinder axis direction;
A rotary actuator comprising side plates that sandwich the left and right ends of the clevis pin in a direction perpendicular to the cylinder axis and connect the front and rear yoke members.
