Abstract:
A vibration motor having mounting hardware with a width dimension able to be kept within a thickness of a motor case, that is, a vibration motor provided with a vibration motor body attaching an eccentric weight to a motor shaft sticking out from a bearing part of a motor case and attaching a pair of motor terminals to a plastic end cap closing an opening of the motor case and with mounting hardware carrying this vibration motor body and to be set on a board, wherein the mounting hardware has a raised bottom flat-shaped part facing a barrel circumference of the motor case, oriented in an axial direction, and to be bonded to mounting patterns on the board, a collar-shaped support piece extending from this raised bottom flat-shaped part and fit over the bearing part in the axial direction, and a plug-in support piece extending from the raised bottom flat-shaped part to the opening side and plugged into first and second positioning slots provided in the plastic end cap in the axial direction.
