Female guide portions (20) for slidingly attaching a battery pack (B) are formed by integral molding of a case main body. Exposed step portions are formed on the female guide portions (20), which includes protruding portions (21) as thin-walled portions by application from the outer side (the upper side) of a mold so as to reduce the thickness of a thick-walled resin portion. An opening communicating with the inner and outer side of the case (11) is not provided, while the protruding portions (21) are formed as thin-walled portions. Bottom surfaces of the exposed step portions (22) are formed so as to be sloped with respect to the horizontal direction when the battery charger (10) is placed on a horizontal base, and water dropped on the bottom surfaces (23) can flow outside of the case (11) due to the slope without remaining thereon. |
