<p>The invention provides an actuator unit. The sway direction of an arm member is not defined and it is difficult for the foreign matter to enter into a case. The said actuator unit (20) comprises a case (21) where an actuator is accommodated, a shaft member allocated inside the case and rotating by the drive of said actuator. The said actuator unit outputs a drive of motor to the exterior of the case via said shaft member. While an opening (87) is provided in a part of said case close to a peripheral surface of said shaft member and a peripheral surface of said shaft member blocks the opening, and rump parts (75),(77),(83) are aranged from the shaft member by the said opening.</p> |
