Abstract:
Provided is a retracting device that can reduce the difference in the restoring force of a tension coil spring between a retracted position and a stop position. This retracting device comprises a base 12, a slider 14 that can trap a trigger 8 and can move relative to the base 12 from a stop position to a retracted position, and a tension coil spring (B) that can move the slider 14 that has trapped the trigger 8 relative to the base 12 from the stop position to the retracted position in order to apply a force to assist closing a sliding door 1. The tension coil spring (B) is an initial tension spring in which when the tension coil spring is at the natural length, the coils are in contact and which has initial tension in the direction that the coils are in contact.
