ラッチバー6は小さい力で円滑に動作するようになる。The attachment / detachment of the battery pack 2 is performed by attaching the battery cases 4 and 5
This is performed by pressing the pressing surface 6a of the latch bar 6 attached to the outer wall surface 4a of the latch bar 6 at a predetermined angle or more outward in the direction of arrow a 'to compress the spring 7. In this case, since the pressing surface 6a is inclined outward by a predetermined angle or more with respect to the outer wall surface 4a, the component force acting as a rotational moment on the rotation center 6c becomes large in the component force of the pressing force. It works smoothly with small force.
