Abstract
In a grinder, a terminal plate is projectingly provided on an upper surface of a controller. A connection portion, which accommodates a female terminal and includes a slit into which the terminal plate enters, is projectingly provided on a lower surface of a main body portion of a switch block. At the time of assembling of the switch block and the controller, the terminal plate that enters into the connection portion from the slit is inserted into and connected to the female terminal. First and second projections that cover a formation surface of the slit in the connection portion when the connection portion is inserted with and connected to the terminal plate are formed on the upper surface of the controller.
