A compact, highly accurate and inexpensive brushless motor is disclosed. A
bearing is fixed to the inner periphery of a cylindrical portion of a
housing, and a shaft is rotatably inserted through the bearing to cover
the housing. A yoke arranged at the forward end of the cylindrical
portion of the housing is fixed on the shaft. In this configuration, the
bearing is arranged at a position on the inside of the yoke, and
therefore the motor can be reduced in size to the extent of superposition
between the yoke and the housing. The bearing is fixed to one member of
the housing, and therefore a high accuracy is realized.
