Patent number: 6392139Abstract: A shield case includes first and second side plates formed by blanking a metal sheet. Between the first side plate and the second side plate, two shield plates are formed connected to the side plates through connecting portions. One shield plate has, in one end edge, a protuberance and, in the other end edge, a shield plate formed through a connecting portion. Bending allowances are formed respectively in the first and second side plate in areas between the connecting portions. During assembling, the bending allowances of the first and second side plates are bent inward between the shield plates.Type: GrantFiled: March 27, 2001Date of Patent: May 21, 2002Assignee: Sanyo Electric Co., Ltd.Inventors: Hideyuki Okuma, Toshiyuki Harada
