Abstract

To prevent harmful glass fiber powders from being produced by abrasing and wearing a circuit board and to dispense with a change in a battery minus terminal when changed to a circuit board having a different thickness. Tongue shape locking spring portions formed at both ends of a minus battery terminal comprising an elastic thin plate are inserted into locking holes of a circuit board and the minus terminal is fixed to the circuit board by a contact pressure produced by bringing the tongue shape locking spring portions into contact with inner walls of the locking holes to be elastically deformed thereby. The tongue shape locking spring portion is constituted by a pair of tongue pieces symmetrical in a left and right direction, and each tongue piece includes a horizontal extended portion and a locking hole inserting portion. The locking hole inserting portion is formed with a projection in a semicircular shape brought into contact with the inner wall of the locking hole.
