However, since the former known technique is constructed such that a separate mounting plate having a function as a supporting substrate of various driving members is interposed between the side frame and the side plate, the manufacturing method is There is a problem that the cost becomes high and it is difficult to maintain the assembly accuracy with high accuracy among the side frame, the mounting plate, and the side plate. Further, in the latter known technique, since the side frame is cut so that the bulging portion is formed, the side frame cannot be easily cut like a circular outer periphery, resulting in a high processing cost. There is.

The present invention has been made in view of the above problems, and in a biaxial fishing reel having a circular side view, a side plate is provided with a large drive member accommodating portion (bulging portion). It is an object of the present invention to provide a biaxial reel for fishing which is capable of reducing manufacturing cost and processing cost while maintaining high assembling accuracy.

[0007]

In order to achieve the above-mentioned object, the biaxial reel for fishing according to the present invention is integrally formed by connecting left and right side frames with a plurality of columns, and has an outer peripheral shape in a side view. Is rotatably supported on a reel body having a circular frame and side plates mounted on the left and right side frames, and a drive mechanism for driving the spool is provided in the side plate. In the configuration housed in, the side plate is formed with a bulging portion that bulges from the outer periphery of the circular side frame, and the opening formed on the frame body side of the bulging portion is separated from the frame body. It is characterized by being closed by the lid member formed in.

According to the above construction, when the side plate having the bulging portion is attached to the side frame portion of the frame body having a circular outer peripheral shape, a large driving member is attached to the bulging portion. ,
For example, a large-diameter drive gear is accommodated. By partially bulging the side plate, an opening corresponding to the bulging portion is formed between the circular side frame and the side plate, but a lid member is separately attached to this portion. The housed drive mechanism is in a sealed state. According to this configuration, the side frame portion of the frame body has a circular shape, and therefore can be easily cut.
