ABSTRACT OF THE DISCLOSURE In a liquidproof battery-powered appliance, a battery insertion opening formed in the bottom of a battery accommodation casing accommodating a rechargeable battery and provided with parts including a motor and a printed circuit board is closed liquidtight by a cover member provided with a gas vent valve, and, after insertion of the battery accommodation casing into a body casing through a bottom opening of the body casing, the bottom opening is closed liquidtight by a flange formed at a peripheral edge of the battery insertion opening of the battery accommodation casing, By the above arrangement, the casings can be simply and reliably sealed liquidtight, and gas that may be generated in a very large amount from the battery in an unusual operating condition can be safely and reliably exhausted to the outside of the appliance.
