Abstract
A brushless motor includes a case fixed onto a yoke to cover an outer surface of the yoke except one end of the yoke in the axial direction, a frame fixed onto the one end of the yoke, a first bearing fixed onto the frame and configured to rotatably support a first end of a rotating shaft in the axial direction, a second bearing fixed onto the case, and configured to rotatably support a second end of the rotating shaft which is closer to the magnet than the first end, the second bearing including a receiving surface that contacts the second end in the axial direction, an energizing member configured to force the rotating shaft from a first bearing side to a second bearing side, and a wiring substrate disposed between the stator and the case in the axial direction and configured to electrify the coil.
