PROBLEM TO BE SOLVED: To provide a motor which can fully exhibit the function of respiration at all times and can be fixed without taking account of the position of a vent in a gear case. SOLUTION: The motor 10 comprises a motor case 11 containing an armature, and a gear case 12 coupled with the opening end of the motor case 11 and containing a deceleration mechanism for decelerating rotation of the armature. A tubular bearing portion 12d from which the output shaft 15 projects is formed in the gear case 12 and a vent 13a for breather is formed therein. A pair of vents 13a and 13a are formed at separated positions opposing to hold the bearing portion 12d of the gear case 12. COPYRIGHT: (C)2008,JPO&INPIT
