摘要：
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.
