Claims

[Claims for Utility Model Registration] {1} A plunger that receives force in the thrust direction, a movable cam integrated with this plunger, a fixed cam provided opposite to this movable cam, and the movable side In the rotary actuator, the rotary actuator is provided with a rolling body that rolls on a cam slope provided on a surface facing the cam and the fixed side cam, and converts force applied in the thrust direction into rotational torque by the rolling body, the fixed side cam and the movable side cam. An inclined surface in a direction opposite to the cam inclined surface is provided at a portion where at least one of the cams corresponds to one of the stop positions, and rotation is stopped by reverse rotation torque generated when the rolling body passes through this reverse inclined surface. An actuator characterized by: (2) The actuator according to claim 1, wherein the transfer body is a ball. (3) Scope of utility model registration request No. 1 where the transferee is Colo
Actuator described in section. (4) The actuator according to any one of claims 1 to 3, wherein both the fixed side cam and the movable side cam are provided with inclinations in opposite directions. (5) The actuator according to any one of claims 1 to 4, wherein the force applied in the thrust direction is an electromagnetic force.
