PROBLEM TO BE SOLVED: To surely prevent the movement of a member integrally formed with a bearing part in the rotation direction in a cylindrical micro vibration motor. SOLUTION: The cylindrical micro vibration motor has a cylindrical motor housing 3-3, a cylindrical field magnet accommodated in the motor housing 3-3, a magnet holding part for holding the field magnet and a bearing part which is provided at the opening part of one end of the motor housing 3-3 and rotatably supports the rotary shaft 4. The bearing part and the magnet holding part are integrally formed using a resin, and engaging parts 16 for engaging with a resin member is formed at the opening part of one end of the motor housing 3-3 so as to prevent the movement of the integrally formed resin member in the rotation direction.
