A motor comprises: a shaft; a permanent magnet rotor in which a permanent magnet and a gear member 32 are united; and a stator, arranged facing the permanent magnet. The gear member 32 has a pinion 33 and a mounting part 34. The mounting part 34 has: a circumferential-direction constraining part 34a, which constrains the circumferential movement of the permanent magnet; axial-direction constraining parts 34b, 34c, which abut both the top and bottom surfaces of the permanent magnet, so as to constrain the axial movement of the permanent magnet; and a plurality of elastic pieces 34d that apply a radially outward biasing force to the inner peripheral face of the permanent magnet.
