Both of the outer peripheral surface 7b of the engaging protruding part 7 positioned on the side of the coming-out direction of a battery holder 2 and the inner peripheral surface 8b of the hole 8a are formed so as to be right-angled to said coming-out direction and the battery holder 2 is prevented from coming out by the engagement of both surfaces 7b, 8b. Therefore, even when a data card is lost by mistake, the engagement of both engaging surfaces 7b, 8b is not released and the holder 2 is certainly prevented from coming out.
