Abstract

To provide a motor which has further improved supporting force and stability of a stator.SOLUTION: A motor (1) of the present invention has a rotor (15), a stator (13) having a coil (139) arranged facing the rotor (15), and a holder (11) holding the stator (13). The stator (13) has an annular part (132) and magnetic pole parts (133 and 134) projecting from the annular part (132) to an outer peripheral side and around which the coil (139) is wound. The holder (11) has a first arm part (117) contacting one face (132a) of the annular part (132) in an axial direction and a second arm part (118) contacting the other face (132b) of the annular part (132) in the axial direction.SELECTED DRAWING: Figure 2
