In the conventional fishing reel having the above-mentioned structure, two or more outer projections 5 are provided to engage the cap 1 with good balance and strength in the cylindrical portion 2. There is a need. However, when the number of the outer protrusions 5 increases, the amount of the tapered surface 7 increases when the number of the tapered surfaces 7 increases, while the tightening allowance for tightening a certain amount of the D dimension of the cap 1 does not change. Tube part 2
If the inclination of the tapered surface 7 formed on the cylindrical portion 2 is not set to a steep angle, the interference of the cap 1 cannot be formed, and if the strength and balance are improved, the tapered surface of the cylindrical portion 2 will be formed at a steep angle. . However, if the inclination of the tapered surface 7 is set to a steep angle, the outer projection 5 of the cap 1 slides easily on the tapered surface 7 even with a small impact, and the cap 1 is loosened. However, there was a problem that it was easily dropped off.

In addition, the dimension D of the small diameter portion 4 of the cap 1, the dimension between the end surface 8 and the tapered surface 7 of the cylindrical portion 2, and the inclination angle of the tapered surface 7 need to be finished with high precision. Dimensional management became complicated, and its manufacture was difficult.
