Abstract: A battery holder includes storage chamber for storing a battery. The storage chamber includes: opening end surface through which battery can be taken in or out; and upper surface section, lower surface section, and first and second side-surface sections (opposing each other) for holding the battery. Projection is formed on the inner wall of first side-surface section at a portion including the end on the opening end surface side. Outward deformable flexible section is formed on second side-surface section at a portion including the end on the opening end surface side. Slit that extends from third side-surface section opposite to the opening end surface toward the opening end surface and stops at the position corresponding to a part of the battery is formed in upper surface section and/or lower surface section. The end of the flexible section is located closer to the third side-surface section than the projection.

Abstract: A compartment accommodates a button cell. The compartment includes an opening side through which the button cell is loaded or ejected from a side surface of the buttons cell. The compartment includes an upper side, a lower side, and lateral sides for holding flat surfaces and the side surface of the button cell. The compartment includes elastic pieces for biasing at least one of the flat surfaces or the side surface of the button cell. A slit is disposed on at least one of the upper side, the lower side, or the lateral sides. The slit extends from a side opposite to the opening side toward the opening side. The slit extends to a part of the button cell.

Abstract: A handy body washer comprises: a main body; a pump accommodated in the main body, a tank, slidably attached to the main body to house the main body therein, and a retractable nozzle member connected to the main body. The nozzle member has a free end and a plurality of nozzle apertures formed proximate the free end. The tank comprises: (i) a bottomed cylindrical body having an open top end and a bottom end, where the bottom end has a water supply opening; (ii) a water supply cover pivotally supported on the bottom end for opening and closing the water supply opening; and (iii) a gutter formed in an inner surface of the water supply cover for introducing the washing water flowing downward into the water supply opening while the water supply cover is open.
