If the spring is used for a long period of time, it deteriorates and the restoring performance is lowered, and the desired biasing action is not exhibited. Therefore, it is necessary to replace the spring periodically. Replacement costs increase. Further, the spring is exchanged by stopping the fitting device. Because it stops, productivity decreases. That is, the fitting device disclosed in Patent Document 1 has two problems, that is, replacement cost and productivity reduction.
