Abstract
A motor comprises: a shaft; a permanent magnet rotor in which a permanent magnet and a gear memberare united; and a stator, arranged facing the permanent magnet. The gear memberhas a pinionand a mounting part. The mounting parthas: a circumferential-direction constraining part, which constrains the circumferential movement of the permanent magnet; axial-direction constraining parts, 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 piecesthat apply a radially outward biasing force to the inner peripheral face of the permanent magnet.
