<p>To make easy mounting/dismounting of a battery case. A lock device 24 and a pop-up mechanism are provided at the front end portion of a main frame 10, and a motor-side connector 26 of a box-like female type is provided at the rear end portion of the main frame 10. An engagement recess 172 is provided at the center on the back surface of the motor-side connector 26. A female type battery-side connector 100 is provided at the rear end portion of a battery case 20, and an engagement projection 104 is provided at the center on the back surface of the battery-side connector 100. When the battery case 20 is slid rearward on the main frame 10 substantially in the direction shown by the arrow Y, the battery-side connector 100 is fitted to the motor-side connector 26. At the same time, the engagement projection 104 is fitted in the engagement recess 172. The front portion of the battery case 20 is lifted by a rocking arm 144 in the state that the locking is released, and is thus placed at the pop-up position shown by the virtual line B. When the front portion of the battery case 20 is depressed and is locked by the locking device 24, the rocking arm 144 is placed at the mounting position shown by the solid line A against the spring force of a tension spring 146, to press the battery case 20 rearward. The battery-side connector 100 and the motor-side connector 26 are certainly fixed to each other, to enhance a contact pressure between the terminals of both the connectors 100, 26. <IMAGE></p> |
