PROBLEM TO BE SOLVED: To eliminate a need for a plurality of unlocking devices having different lengths which arise from existence of unlocking devices having different lengths even if the locking devices for installed game machines are changed entirely so as to unify keys in a hall because of different keys used for the unlocking devices dependent on manufacturing companies or models. SOLUTION: The electric unlocking device has a motor 1a built in a cylindrical case. The cylindrical case has a three-part structure, in which a top case 1 is joined to a bottom case 2 through a joint case 3 having a connecting shaft 3a built in. A plurality of joint cases 3, 3' and 3'' having different lengths are prepared for interchange. COPYRIGHT: (C)2006,JPO&NCIPI
