The main body includes an inside portion having a shape of empty rectangular cylinder, an electromagnet(111), and a guide hole(113). The contact point is electrically connected to a coil of the electromagnet. The vibrating body includes a head(131) and a guide bar(133). The guide bar is inserted into the guide hole of the main body. The elastic body is adhered on one side of the main body in order to provide the elastic force to the vibration body.
