Claims

[Claims for Utility Model Registration] 1. A rotary actuator in which a shaft hole is formed in the rotor portion, and an output shaft is passed through the shaft hole to enable transmission of rocking force, The output shaft assembling means includes a pair of female multipliers offset from each other on the inner peripheral surface of the shaft hole of the rotor portion. A rotary actuator characterized in that a saw blade portion is formed by overlapping polygons, and a male polygon corresponding to the female polygon is formed on the outer peripheral surface of the output shaft. 2. The rotary actuator according to claim 1, wherein the male polygon and the female polygon are a male regular quadrilateral and a female regular quadrilateral. 3. The rotary actuator according to claim 1, wherein the male polygon and the female polygon are regular male hexagons and regular female hexagons.
