PURPOSE:To extremely simplify the replacement of new and old cells by providing a male screw on the outer periphery of a fitting section (f), providing an insulating disk having in its center a conductor elastically in contact with the positive electrode of the cell inside the fitting section, and engaging a female screw separately provided on the inner periphery of the opening edge of a conductive cell storage case with the male screw on the outer periphery of the fitting section (f). CONSTITUTION:In a frame section A, one side of a partition wall (d) having a through hole (c) in the center is made the fitting section (e) of the second cylinder II, and the other side is made a cell fitting section (f), a male screw (g) is provided on the outer periphery of the cell fitting section (f), an insulating disk (k) having in its center a conductor (j) capable of elastically getting in contact with the positive electrode (i) of a cell B via an enclosed coil spring (h) is provided, the cell B is separately stored inside, and the female screw (n) provided on the inner periphery of the opening edge (m) of a conductive cell storage case C in contact with the negative electrode (l) of the cell B via an elastic conductive plate (r) is engaged with the male screw (g) on the outer periphery of the cell fitting section (f). For replacement of new and old cells, the opening edge (m) of the cell storage case C is unscrewed from the cell fitting section (f) of the frame section A to remove the cell storage case C, and the old cell is taken out. |
