ABSTRACT:
In a vibrating motor, an eccentric weight is attached to one end of a rotation shaft that projects linearly from a motor housing. The vibrating motor causes the gravity center of the weight to rotate about the rotation shaft so as to produce a vibration. A disk-shaped anti-bending piece is provided on the rotation shaft coaxial with it. This anti-bending piece faces an anti-bending surface provided on some kind of supporting member when the housing is supported by the member, the piece being situated at a predetermined distance from this surface. If the shaft bends, the piece strikes the surface and the linear shape of the shaft is restored due to its own elasticity. Hence, even if the motor suffers an unexpected load, the rotation shaft does not buckle due to the weight of the eccentric weight.
