Claims

[Scope of utility model registration request]

A contact spring member made of a conductive and elastic wire and spirally wound so that the diameter decreases from one end to the other end is attached to the side wall of the battery storage chamber, and the battery is inserted into the battery storage chamber. When the battery is inserted, the electrode surface of the battery is brought into contact with the other end of the contact spring member, and by compressing the contact spring member, the battery is electrically and mechanically operated by the contact spring member in the battery storage chamber. In the battery storage device connected to the battery storage chamber, a pair of inverted pieces forming a groove into which one end of the contact spring member is inserted are arranged in parallel on the side wall of the battery storage chamber, and the pair of inverted pieces form a groove into which one end of the contact spring member is inserted. A first protrusion having an inclined surface or a curved surface that gradually becomes higher from the other end of the pair of inverted pieces is provided on the side wall of one end of the shaped pieces, and one end of the contact spring member is connected to the groove of the inverted pieces. When the first protrusion is inserted into a surface opposite to the slope or curved surface after contacting the slope or curved surface, the - of the wooden member comes into contact between it and the first projection.
1. A battery contact spring member locking device characterized in that a second protrusion is provided to form a gap in which the end of the battery contact spring member is inserted.
