Abstract

PURPOSE:To facilitate the discharge of resin sawdust powder upon assembling by preliminarily cutting a vertical groove on opposing faces of a penetration hole for threading a tapping screw for connection in forming a small housing composed of a cover and a case by the use of a thermosetting resin. CONSTITUTION:A cover 5 and a case 6 are formed with a molding material, and a tapping screw 7 is threaded in a screw hole communicating these members 5, 6 each other to form a relatively small housing for circuit breaker. At the lower end of the hole, a board member 6E corresponding to the lower half of a case 6, and a female screws 6a are cut while a vertical state is assured on the upper side, and this time, a groove 6b is vertically cut deeper than the outer dia. of the tapping screw 7 on the opposing female screws 6a. It is thus possible to drop resin powder cut along the groove 6b by the screw 7 in integrat ing the cover 5 and the case 6, without mixing thereof inside the case.
