<P>PROBLEM TO BE SOLVED: To provide an actuator capable of reducing an impulsive hitting sound in a thrust direction of a rotary shaft without enhancing accuracy in a dimension error of parts and assembly. <P>SOLUTION: The actuator 1 includes a case 10, a motor 20 arranged in the case 10 and provided with a worm 26 fixed to the rotary shaft 21, and gears 30 engaged with the worm 26. In the case 10, a thrust receiving part 13 restricting thrust movement of the rotary shaft 21 is arranged on a front end side of the rotary shaft 21 of the motor 20. The case 10 and the motor 20 are respectively provided with fixing means adjusting the position in the axial direction of the rotary shaft 21 and fixing the motor 20. The fixing means comprises a motor-side fixing means arranged on the motor 20 and formed into a shape of a linear projection or of a groove formed in the axial direction of the rotary shaft 21, and a case-side fixing means engaged with the motor-side fixing means, arranged in the case 10, and formed into a shape of a groove or a linear projection formed in the axial direction of the rotary shaft 21. <P>COPYRIGHT: (C)2012,JPO&INPIT |
