Abstract:
A motor includes: a motor shaft including a press-fitting surface; and a first annular projection group and a second annular projection group formed in the press-fitting surface of the motor shaft. The first annular projection group and the second annular projection group are separated from each other in an axial direction, a distance between an adjacent two of annular projections in the first annular projection group and a distance between an adjacent two of annular projections in the second annular projection group are smaller than a distance between the first annular projection group and the second annular projection group in the axial direction.
