Claims

[Scope of utility model registration request]

A bearing, a bearing holder to which the bearing is fixed, a rotating shaft rotatably supported by the bearing, a cup-shaped rotor case fixed to the rotating shaft, and an annular permanent ring disposed on the inner surface of the rotor case. In a small motor equipped with a magnet and a stator core whose outer periphery faces the inner surface of the permanent magnet and which is attached to one side of the bearing holder, the rotor case is connected to the rotating shaft via a boss made of a synthetic resin magnet. A small motor in which the boss is fixed to the stator core and magnetically attracted to the stator core.
