Abstract

Female guide portions for slidingly attaching a battery pack are formed by integral molding of a case main body. Exposed step portions are formed on the female guide portions, which includes protruding portions 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 is not provided, while the protruding portions are formed as thin-walled portions. Bottom surfaces of the exposed step portions are formed so as to be sloped with respect to the horizontal direction when the battery charger is placed on a horizontal base, and water dropped on the bottom surfaces can flow outside of the case due to the slope without remaining thereon.
