Provided is a retracting device which can decrease a difference of restoring force of a tension coil spring between a retracted position and a stop position. The retracting device of the present invention includes a base 12, a slider 14 which can catch a trigger 8 and move from the stop position to the retracted position with respect to the base 12 and a tension coil spring (B) for relatively moving the slider 14 which has caught the trigger 8 from the stop position to the retracted position with respect to the base 12 to apply force for assisting the closing operation to a sliding door 1. The tension coil spring (B) is an initially-tensioned spring in which a coil closely contacts and which has initial tension in a direction in which the coil closely contacts when it is in a natural length.
