2. Description of the Related Art A spinning reel is generally provided with a reel body mounted on a fishing rod, a spool for a bobbin mounted on a tip end of a spool shaft which moves back and forth with respect to the reel body, and a rotatable mount mounted on the reel body. And a rotor for winding the fishing line around the spool. A spool of this type of spinning reel has a bobbin trunk around which a fishing line is wound, a flange portion having a larger diameter than the bobbin trunk, and a skirt extending rearward from an outer peripheral portion of the rear flange portion and integrally formed with the rear flange portion. And a front flange provided at the front end of the bobbin trunk.

Recently, in order to reduce the weight of the spool while maintaining the high-grade appearance of the design, the bobbin trunk is made of a relatively hard synthetic resin such as nylon 66, and the rear flange portion and the skirt portion are formed on the surface thereof. A spool equipped with a sheet metal press-molded product has been developed. In this type of lightweight spool, the front flange portion is easily damaged and worn due to contact with the fishing line, so a hard metal thick material such as stainless steel is used in consideration of abrasion resistance and durability. The bolt is fixed to the part by a method such as screwing.

[0004]

In the conventional spool, the skirt portion is formed integrally with the surface of the bobbin trunk as a press-formed product made of a sheet metal, so that the weight of the bobbin trunk and the skirt can be reduced. . However, since the front flange portion is made of a metal such as a stainless alloy, it is difficult to reduce the weight while maintaining wear resistance and durability.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a spool for a spinning reel, which can maintain the wear resistance and durability of a front flange portion and reduce the weight of the spool as much as possible.
