TECHNICAL FIELD OF THE INVENTION
The present invention relates to a reel body, and more particularly, to a reel body of a spinning reel having a storage space in which an oscillating mechanism is stored.
[0002]
[Prior art]
A spinning reel generally has a reel body mounted on a fishing rod, a handle rotatably mounted on the reel body, a rotor rotatably mounted on the reel body, and a front-rear movable front-rear to the reel body. And a spool around which the fishing line guided by the rotor is wound.
[0003]
The reel body includes a T-shaped rod mounting leg mounted on a fishing rod, and a reel body integrally formed with the rod mounting leg. The reel body houses therein an oscillating mechanism having a screw shaft having a spiral groove formed on the outer periphery and a slider that moves back and forth along the screw shaft. Further, the reel body includes a main body member having a storage space in which a side portion opens, and a lid member detachably attached to the main body member so as to cover the opening of the main body member. The lid member is screwed and fixed to the main body member. A hole is formed at the rear end of the main body member to support the end of the screw shaft of the oscillating mechanism. In such a spinning reel, after the screw shaft is inserted from the hole, the closing member is screwed and fixed to the main body member to close the hole.
[0004]
[Problems to be solved by the invention]
In the conventional spinning reel, a closing member that closes a hole in which the end of the screw shaft is supported is screwed and fixed to the main body member. Here, generally, the thrust force in the front-rear direction of the spool acts concentrated on the screw shaft via the spool shaft. When the thrust force acts on the screw shaft in a concentrated manner, the closing member is pushed rearward through the end of the screw shaft, and the thrust force acts on the screw member fixing the closing member. For this reason, it is necessary to employ a screw member having a large diameter according to the acting thrust force. However, if a screw member having a large diameter is used, the reel body may be increased in size.
[0005]
An object of the present invention is to prevent a reel body of a spinning reel from being enlarged.
