PURPOSE:To prevent the damage of a power source case, the danger to a human body, and the like, owing to a jumping out of the power source case, by forming a locking claw to fit to a notch of the power source case, and providing stoppers to insert to grooves for preventing the jumping out. CONSTITUTION:When a power source case 1 is installed in a guide case 2, the guides B14 of the case 1 is fitted and pushed into the guides 25 of the case 2. In this case, the locking members 13a of guides A13 pass through the projections 26 of the case 2, and a locking claw 22 is inserted to a notch 12 of the case 1 and locked. When the case 1 is drawn out, the case 1 is drawn out after the claw 22 is moved in the direction of the arrow C' to release the locking condition. In this case, stoppers 3 abut on the walls 11a of grooves 11 for stoppers 3 to prevent the jumping out to limit their drawing out. And when the case 1 is drawn out further, the stoppers 3 cross over the walls 11a and the case 1 can be drawn out of the case 2. Consequently, the jumping out of the power source case 1 can be prevented, and a damage of the power source case and the danger to a human body can be prevented. |
