摘要：
Provided is a position holding device for a rotating lever, which includes a rotating lever and a torsion spring, and is capable of elastically holding the rotating lever at the two positions including a first position and a second position. The torsion spring includes a coiled part, and a first arm part and a second arm part each extending from the coiled part and facing each other across an engagement portion of the rotating lever. The first arm part includes a mountain portion formed at an intermediate portion thereof. The second arm part includes an urging portion. As a result, an urging force generated by the urging portion can be applied to the rotating lever as a braking force against an urging force generated by the mountain portion. Consequently, it is possible to reduce an abutment noise generated when the rotating lever abuts against a stopper member.
