Abstract
In a vibration motor, insulators are provided with protrusions that are positioned radially inward from extension portions, provided at an end portion of a body of a weight, and that restrict radial movement of the extension portions. In addition, in the vibration motor, the weight is supported by the protrusions of the insulators so as to prevent the weight from falling radially inward. Therefore, when using the vibration motor, the situation in which a force acting radially inward upon the weight is supported only by a weld or an adhesive is prevented from occurring, so that a gradual reduction in the securing strength of the weight does not occur. The insulators can prevent the weight from falling when assembling the vibration motor.
