摘要： In a vibration motor holding structure for retaining a vibration motor having eccentric weights at rotation shaft ends and holding the vibration motor on a circuit board, there is provided a metal holder having support legs provided along a part of the length of the vibration motor and protruding horizontally in the direction orthogonal to the longitudinal direction of the vibration motor on both sides thereof. Thus, the vibration motor can be prevented from falling over during the mounting process and be held on the circuit board at solder-applied positions.

摘要： A motor includes (a) a stator having a stator core wound with a coil, (b) a rotor having a magnet facing the stator core via an annular space and a yoke disposed on an outer wall of the magnet, and (c) an unbalancing weight disposed on an outer wall of the yoke. This structure allows the motor to be small in size, light in weight, thin, flat and to function as a vibrating motor producing maximum vibration at low power consumption. The motor thus contributes to realizing a portable device with a small size, a low weight, and which is operable for many hours.
