PROBLEM TO BE SOLVED: To compensate rotational precision and life time of a motor, without applying unnecessary stress to the output shaft and inner structure body of the motor by allowing the cabinet of the motor to be displaced to the direction, wherein the motor rotation shaft slants with respect to an equipment main body, and restraining the displacement to the rotating direction around the motor rotation shaft. SOLUTION: Motor cabinets (a lower case 13 and an upper case 14) can slant with respect to a motor fixing surface 2a in accordance with the direction of an output shaft 11 held by a ball bearing 25, so that unnecessary stress is not applied to the output shaft 11 itself and the inner structure body of a motor 10 (a stator 20, a rotor 19, etc.). In a flange part of the lower case 13 of the motor 10, a long hole 13b stretching in the radial direction of the motor 10 is formed, into which a stepped vis 27 is inserted and fitted. As a result, rotational displacement around the rotational shaft of the motor 10 with respect to a motor fixing base 2 of the motor cabinets 13, 14 is restrained, and a body 41 to be driven can be surely rotated and driven by the motor 10. |
