Claims

[Scope of utility model registration request]

At least one contact point of a battery chamber into which a battery having a ring-shaped protrusion protruding in the axial direction along the outer periphery from the cylindrical end can be inserted from the lateral direction perpendicular to the cylindrical axis is formed by a conical coil spring, An arm extending in a direction opposite to the direction in which the battery is taken out is provided at the small-diameter winding end of the conical coil spring that is in contact with one pole, so that the arm part rides on the ring-shaped protrusion when the battery is taken out. A contact spring device for a battery chamber, characterized in that:
