To improve manufacturability by reliably infiltrating an adhesive between the outer side of a bearing and the inside of a motor head of a case while preventing the adhesive from penetrating into the bearing.
The motor has a bearing cap 16 which has an outer diameter smaller than an outer race and larger than an inner race of a bearing 15, covers one end of the bearing 15, and prevents an adhesive from penetrating into the bearing 15. A thrust spring 17 is provided between the bearing cap 16 and the motor head 11, which applies a pre-load to the bearing 15 by biasing the bearing cap 16 toward one end of the bearing 15. A hole 19 for injecting an adhesive between an outer periphery of the bearing 15 which pivots a rotating axis 14 rotatably and an inner periphery of the motor head 11 of a frame 4 to attach the motor body is provided to a thrust receiving wall 11a of the motor head 11 along the axial direction. By only injecting a relatively small amount of adhesive in one direction along the axial direction, the adhesive is reliably infiltrated between the inner periphery of the motor head 11 and the outer periphery of the bearing 15, and manufacturability can be improved.
