Is forged integrally with the bobbin trunk 7a so as to cover the body. As shown in FIG. 4, a groove 7c to which the fishing line locking portion 70 can be attached is formed on the front end side of the outer periphery. A through hole 7d penetrating the skirt 7b is formed at the front end of the groove 7c. A locking pin 7e protruding rearward is formed on the inner peripheral side of the front end of the skirt 7b.

As shown in the enlarged view of FIG. 4 and FIG. 5, the fishing line locking portion 70 includes a locking portion 70a facing the outer periphery of the groove 7c and exposed to the outside and a locking portion 70a. And a mounting portion 70b that is bent substantially at a right angle, extends through the through hole 7d, and extends into the skirt portion 7b. The locking portion 70a
It is for holding and locking the fishing line together with the outer peripheral surface of the skirt portion 7b, and has a tip portion 70c extending rearward. By lifting the tip portion 70c, a gap is formed between the locking portion 70a and the skirt portion 7b (see FIG. 6). The fishing line is locked in the locking portion 70a by sandwiching the fishing line in the gap (see FIG. 7).

The mounting portion 70b is in contact with the front end of the skirt portion 7b, and has a mounting hole 70d into which the locking pin 7e is inserted. To attach the mounting portion 70b to the skirt portion 7b, a locking pin 7e is inserted into the mounting hole 70d, and the locking metal fitting 8 is attached to the head of the locking pin 7e protruding from the mounting portion 70b.

The diameter of the hole 80a is formed to be smaller than the diameter of the locking pin 7e, and four notches are formed in the inner diameter of the hole 80a. When the hole 80a is pushed into the locking pin 7e, the inner diameter portion is widened and clamped in the direction of sandwiching the locking pin 7e, so that the locking fitting 80 is fixed to the locking pin 7e.

The locking portion 70a and the mounting portion 70b are integrally formed of an elastically deformable synthetic resin. In particular, as shown in FIG. 5, the mounting portion 70b has a bent shape, and therefore, can be easily elastically deformed (expanded or contracted) in the radial direction of the skirt portion 7b. Here, the mounting portion 7
0b is set in a slightly extended state, so that the locking portion 70a is constantly urged to the peripheral side without the skirt portion 7b.

The flange portion 8 is a scratch-resistant disk-shaped member made of metal or hard ceramic and formed so as to be inclined forward toward the outer periphery.

The drag mechanism 60 includes a knob 61 for manually adjusting the drag force, and a plurality of drag plates 62 pressed toward the spool 4 by the knob 61. In the embodiment having such a configuration, after the fishing line is wound around the spool 4, the front end portion of the fishing line is locked to the fishing line locking portion 70. In order to lock the fishing line to the fishing line locking portion 70, the fishing line is penetrated from the front end 70c side of the locking portion 70a so as to sandwich the fishing line. At this time, the mounting portion 70b
Since the locking portion 70a is urged toward the inner peripheral side of the skirt portion 7b by the elastic force of the above, the fishing line is firmly held and locked between the locking portion 70a and the groove portion 7c of the skirt portion 7b.

In such a spool 4, the fishing line is locked by the elastic force acting on the locking portion 70a, so that the mounting portion 70b, which is elastically deformable, locks the fishing line. The locking portion 70a is less likely to be sagged than that locked by utilizing Also, the force by which the mounting portion 70b urges the locking portion 70a toward the inner peripheral side of the skirt portion 7b,
Since it operates even after the fishing line is locked, the fishing line can be reliably locked.
