[Problems to be solved by the device]

 However, in these conventional examples, in the case of using the former leaf spring having the cut-and-raised pieces, the work of pressing rotation is troublesome and quick attachment / detachment operation cannot be performed, and at the same time, the cut-and-raised portion of the leaf spring is not affected when pressing and rotating. There is a problem that the dowel pin is easily caught and deformed. The latter push-button release type improves the attachability / detachability, but cannot reliably control the play in the front-rear direction of the spool, so the front-rear direction of the spool relative to the spool shaft can be prevented. The position cannot be reliably maintained at a fixed position, which causes a problem that the fishing line wound around the spool is not stable and varies.

Therefore, the present invention enables quick attachment / detachment operation, regulates unnecessary movements of the spool in the front / rear direction and the rotation direction, and reliably maintains the spool in a fixed position, so that a stable fishing line state can be obtained. The purpose is to provide a spinning reel.
