Abstract
Disclosed is a vibration motor. The vibration motor includes a bracket including a support tube protruding from the bracket, a case coupled with the bracket, a support shaft supported by the bracket and the case, a bearing rotatably fitted around the support shaft, a rotor fixed to the bearing to rotate together with the bearing, thereby generating vibration, a stator mounted on the bracket to rotate the rotor through interaction with the rotor, a support member installed around the support tube, and a first washer interposed between the support tube and the bearing and supported by the support member.
