Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor fixed to a circuit board, the motor capable of preventing, compared to conventional motor, more damage to a root portion of an elastically deformable engagement projection that engages with an engagement hole formed in the circuit board.SOLUTION: In a motor 1 fixed to a circuit board 7, a stator 6 comprises: a bearing 31 with a mounting face 31f composing part of a front end face of the stator 6 and abutting on the mounting face 7c of the circuit board 7; and an engagement member 32 with an engagement projection 32a engaged with an engagement hole 7a in the circuit board 7. The engagement projection part 32a extends frontward so as to be elastically deformable at least in a radial direction, and the root of the engagement projection part 32a is arranged behind the bearing 31. The bearing 31 has an insertion hole 31e in which the engagement projection 32a is inserted, and the leading end of the engagement projection 32a projects further forward than the mounting face 31f.SELECTED DRAWING: Figure 3
