Abstract: A DC motor including: a substantially cup-shaped housing; and an attachment board which closes an opening of the housing, and to which the motor is attached in a predetermined position; wherein the board has a fitting portion which is provided at a central part of this board, and to which a bearing on one side of a rotor shaft placed in the housing is fitted, and an arm formed protruding in a radial direction at an outer circumferential part of the attachment board, and fastened to an attachment member.

Abstract: A stepping motor for generating vibration is provided and includes a stator and a rotor. The rotor includes a shaft, a ring magnet and a rotor frame, and the rotor frame is formed into a substantial cup-shape including a disk portion having an opening at the center and also including a cylindrical portion continuously arranged at the periphery of the disk portion, and a weight portion is arranged in a portion of the rotor frame so that the gravity center of the rotor frame an be located at a position eccentric with respect to the center of the rotor frame.
