Disclosed is an inexpensive structure for mounting a flexible printed circuit board to a hard circuit board without using a connector. The terminal section of the flexible printed circuit board is mounted to a holding member, which is secured to the hard circuit board to electrically connect the wiring pattern of the terminal section to the electric circuit of the hard circuit board, whereby it is possible to mount the flexible printed circuit board to the hard circuit board without using an expensive connector, thereby achieving an improvement in terms of cost and operability.

The invention relates to a motor, and more particularly to a motor having means for detecting an index position. A rotor yoke of the motor is provided with a recess having a width greater than the width of each pole of a rotating magnet. Substantially the whole of one pole of the rotating magnet and a part of another pole adjacent to the one pole on the downstream side in terms of rotation of a rotor are exposed to the recess. The magnetic flux from the magnet exposed to the recess is detected by a Hall element disposed in opposition to the outer circumference of the rotor, thereby specifying the index position.
