[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel in which damage to a coating film surface subjected to coating treatment is prevented.

[0002]

2. Description of the Related Art In a conventional fishing reel, for example, when attaching a lid plate to a reel body with a tightening screw, a conventional example drawing,
The current situation is to tighten and fix by the method as shown in FIGS. 7 to 10 and Japanese Utility Model Laid-Open No. 57-146878. 7 to 9
Of the tapping screw hole 1f and screw hole 1g in the main body 1 "
When the cover plate 2 ″ is formed with the recess 2f and the through hole 2g and is tightened with the tightening screw 3 ″, the head 3d is placed on the recess 2f. Further, in FIG. 10, the recess is not formed in the cover plate 2 ″, the synthetic resin washer 32 is placed on the coating surface 4g on the cover plate 2 ″, and the cover plate 2 ″ is attached to the main body 1 ″ with the tightening screw 3 ″. There is.

In the current situation as shown in FIG. 7 to FIG. 9, the surface of the cover plate 2 ″ is coated, and the head 3d of the tightening screw 3 ″ is recessed.
When placed on 2f and tightened, in the final step of tightening the tightening screw 3 ″ by the driver, strong rotation during tightening occurs between the bottom surface of the head 3d of the tightening screw 3 ″ and the coating surface 4g on the recess 2f. A force acts in the direction to pull the coating film on the coating surface 4g near the outer periphery of the head 3d and peel it off, exposing the base material. Also in the case of FIG. 10, when the head 3d is placed on the synthetic resin washer 32 and tightened, in the final step of tightening the tightening screw 3 ″, the head 3d of the tightening screw 3 ″ and the synthetic resin washer 32 rotate together. Then, the coating film 4g near the outer periphery of the synthetic resin washer 32 is pulled and peeled off, and the base material is exposed. If the base material is exposed, seawater, water, foreign matter, etc. are likely to adhere to the fishing ground in a severe operating environment. However, there are still problems such as poor corrosion resistance.

[0004]

In the final step of tightening the tightening screw 3 ″ by the driver, the surface of the lid plate 2 ″ is painted, and the bottom surface of the head 3d of the tightening screw 3 ″ and the recess 2f are formed. A strong force in the direction of rotation acts during tightening between the coating film surfaces, the coating film on the recess 2f near the outer periphery of the head 3d is pulled and peeled off, the base material is exposed, seawater, water, foreign matter, etc. In a fishing place where the environment where rust tends to adhere is severe, corrosion often occurs in the vicinity of the head 3d of the screw 3 and promotes corrosion, which is inferior in terms of corrosion resistance. An object of the present invention is to provide a fishing reel in which the coating film surface in the vicinity of the outer periphery of the head of the tightening screw is prevented from peeling.

[0005]

DISCLOSURE OF THE INVENTION The present invention is a fishing reel in which the surface of a base material of a constituent member of a reel is coated and screwed, and the constituent member coated with the composition is used. The gist is that the head seat of the tightening screw is formed in a ridge shape having a diameter smaller than the outer diameter of the head.

By the means for solving the problems, when the cover plate 2 is overlaid on the main body 1 and is attached by the tightening screw 3,
The screw portion 3b of the tightening screw 3 inserted into the through hole 2c of the cover plate 2 is screwed into the screw hole 1b of the main body portion 1. Tightening screw 3 at this time
The bottom surface 3c of the head 3a is placed on the coating surface 4c on the top surface of the seat 2b. When the tightening screw 3 is tightened with a screwdriver, a tightening force acts on the bottom surface 3c of the head 3a and the coating surface 4c on the top surface of the receiving seat 2b, and the coating surface 4c and the coating surface 4b on the outer periphery of the receiving seat 2b. Cracks may occur between them. However, since the coating surface 4c and the coating surface 4b are connected to each other by a right-angled surface, it is possible to prevent the coating surface 4b on the outer periphery of the seat 2b from being peeled off due to the occurrence of a crack on the right-angled surface.
