Claims

[Scope of utility model registration request]

The outer diameter of the hollow coil spring through which the cord is inserted, in cases where the case is attached to the vertical frame of a door that is attached to the door frame via a hinge mechanism so that it can be opened and closed, and the case is attached to the corresponding position within the door frame. Holes with a slightly larger diameter are bored at corresponding positions on the front plates of both cases, and the hollow coil spring is loosely fitted into the holes so as to straddle between both cases and be arranged horizontally without being cut out. The other end of the movable piece, which is pivotably pivoted with one end on a shaft, is engaged with the end of the hollow coil spring in the door-side case, and is spring-loaded. A current-carrying metal fitting characterized in that the movable piece is rotated and biased in a clockwise direction.
