2. Description of the Related Art Generally, a spinning reel includes a reel body that rotatably supports a handle, a rotor, and a spool. The spool of the spinning reel is movable back and forth with respect to the reel body, and has a bobbin trunk around which fishing line is wound, a large-diameter flange portion arranged at the front end of the bobbin trunk, and a bobbin trunk behind the bobbin trunk. And a skirt portion formed integrally with the portion. The flange portion is fixed to the bobbin trunk by a flange fixing member. And
The skirt portion is provided with a fishing line engaging portion for engaging the fishing line wound around the bobbin trunk.

Such a fishing line locking portion is for locking the tip portion of the fishing line to prevent the fishing line from scattering. The fishing line locking portion has a locking portion made of synthetic resin and a plate-shaped mounting portion integrally formed with the locking portion. The locking portion is exposed, for example, along the outer peripheral surface of the skirt portion, and is arranged with a slight gap from the outer peripheral surface of the skirt portion. The mounting portion is bent at a substantially right angle from the locking portion, penetrates a through hole formed in the skirt portion, and is fixed to the front end portion on the inner peripheral side of the skirt portion. In such a fishing line locking portion, the fishing line is held in the gap formed between the locking portion and the skirt portion, and the fishing line is locked by the elastic force of the synthetic resin in the locking portion.
