To effectively prevent positional deviation of a battery. A hook-shaped member (109) of a first electrode terminal (102), and hook-shaped members (106,108) of a second spring electrode terminal (103,104) are arranged in respective apices of a regular triangle to restrict movements of a battery in a direction along a cross section against the bias of a third spring electrode terminal (113), which abuts against a surface (116), of negative polarity, of the battery. Battery abutments (111,105,107) are arranged in respective apices of a substantially regular triangle to permit the bias of the respective spring electrode terminals to bias the battery toward the battery abutment, thus restricting positional deviation of the battery in a horizontal plane. When the battery is to be removed, a battery removal tool arranged near the hook-shaped member is inserted into a tool insertion portion to remove the battery. <IMAGE>
