Description

  The present invention relates to a dual bearing reel for fishing that rotatably supports a spool around which a fishing line is wound between side plates of a reel body, and rotates the spool by rotating a handle provided on one side plate.

  In a fishing reel called a double-bearing reel, a reel body that rotatably supports a spool includes, for example, a left and right annular side frame and a support provided between the side frames as seen in Patent Document 1. In addition, the outer plate is attached to the side portion of the frame integrally molded with the fishing rod mounting portion.

Normally, the above-mentioned frame is made by mold molding, and the outer periphery on which the holes, screw holes and outer plates of the parts where various functional parts are mounted and inserted are mounted on both sides of the frame after the mold is mounted. The shape is cut. At this time, conventionally, by using the positioning shape formed on the side of the frame at the material stage at the time of molding the mold, it is possible to maintain the accuracy of the part (such as the hook mounting portion and the support column) integrally formed between the frames on both sides of the frame. It is processed and formed into a shape (final contour shape such as a saddle mounting part and a column) (first processing step). Then, using this processed shape as a proof, holes on both sides of the frame, screw holes, outer plates Cutting processing (second processing step) such as assembling certificate and outer peripheral shape is performed.

  As described above, in the conventional manufacturing process of the reel main body, the first processing step of cutting the portion between the side frames based on the positioning shape formed in the material stage (die molding) of the frame side portion and forming the processing certificate. And the second processing step for cutting the holes on both sides of the frame based on the processing certificate formed in the part between the side frames, the outer plate incorporation certificate, and the outer peripheral shape, etc. The number of setup changes and the number of processes increases, and the processing cost tends to be expensive.

  In particular, when the frame outer periphery is not a round shape (unshaped) and there is a portion that is not subjected to peripheral cutting, the frame outer peripheral portion and the outer plate assembly certificate formed in the second processing step are included. A large step is likely to occur due to the accumulation of variations in the processing dimensions of the first processing step and the second processing step in the outer periphery matching portion with the outer plate based on the above, and a good appearance cannot be obtained. Challenges remain.

  The present invention has been made paying attention to the above-described problems, and provides a double bearing reel for fishing that can reduce the processing cost and can be finished in a good appearance. Objective.

  In order to achieve the above-mentioned object, a fishing double bearing reel according to the present invention includes a frame formed by left and right side frames and a support column formed integrally between the side frames, and a side portion of the frame. A reel body configured to include an outer plate attached to the spool, a spool rotatably supported between the outer plates of the reel body, and driven to rotate by operating a handle provided on one outer plate; And a reference hole for defining a processing reference position is formed in the support column of the frame at a material stage during mold molding.

  In the double-bearing reel for fishing having the above-described configuration, a reference hole is formed in the support between the side frames of the frame at the material stage of the frame (meaning a state formed by a mold). Then, the frame is positioned using this reference hole as a processing certificate, and the entire frame is cut, specifically, the screw hole formed on the side of the frame is cut, and the mounting certificate is cut to incorporate the outer plate. Processing, cutting of the outer peripheral surface and the like are performed. Such cutting of the entire frame can be performed in a single work process by using the reference hole of the support column between the side frames formed at the material stage as a proof. The number can be reduced. In addition, since only one cutting process is required, it is possible to finish the appearance beautifully without accumulating variations in processing dimensions.

  The above-mentioned “reference hole” may be a structure having a bottom part, or a concept including both a structure having no bottom part (a so-called “through hole”).

  According to the present invention, it is possible to reduce the processing cost, and it is possible to obtain a fishing double-bearing reel having a good appearance.
