The edge angles β and α of the butted surface to the surfaces of the front cover 7 and the side cover 6a or 6b are in the ranges of 70 to 110 degree and 110 to 70 degree, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component assembly, and more particularly to a component assembly for a fishing reel having at least a part of a surface formed by a three-dimensional curved surface.

2. Description of the Related Art In fishing reels such as spinning reels and dual-bearing reels, component assemblies composed of three-dimensional curved surfaces are frequently used in consideration of design and functions. For example,
A reel body (an example of a component assembly) of a dual-bearing reel or a spinning reel is assembled by a plurality of components each having a three-dimensional curved surface. In the case of manufacturing a part constituted by a three-dimensional curved surface, forming a three-dimensional curved surface by machining makes the processing complicated and increases the processing cost. Therefore, it is usually manufactured by a molding method using a mold. For example, in the case of a part made of synthetic resin, it is manufactured by a molding method such as injection molding, and in the case of a part made of metal, it is manufactured by a molding method such as die casting. When a component assembly is formed by abutting two parts having different mold dividing directions at a three-dimensional curved surface portion, conventionally, abutting surfaces are arranged along the direction in which any of the parts is removed from the mold. Therefore, depending on the shape of the three-dimensional curved surface of the butted portion,
The edge on one surface side may be extremely acute, and the edge on the other surface side may be extremely obtuse. For example,
When a reel body is configured by abutting a side cover of a conventional dual-bearing reel and a front cover also serving as a thumb rest, abutting surfaces are often arranged along a direction in which the side cover is removed. For this reason, the front-side edge of the butted portion of the front cover formed by the mold divided into front and rear portions of the reel has an acute angle, and the side cover formed by the mold divided into right and left of the reel has an obtuse angle. Then, the mold is divided at the edge portion in order to keep the sharp edge in a sharp state so as not to be dull. In this way, parts can be smoothly removed from the two divided molds.

In the above-mentioned conventional configuration,
Since the mold is divided by the sharp edge, burrs are easily generated at the tip of the sharp edge. When burrs occur, they feel uncomfortable when their palm or finger touches the boundary. Therefore,
When burrs occur, deburring work is performed to remove the burrs. However, since the edge is at an acute angle, it is difficult to distinguish between the burr and the edge, and there is a possibility that the edge other than the burr may be cut off by the deburring operation. If the edges other than the burrs are cut, gaps are excessively formed at the butted portions, and the gaps are conspicuous, causing a problem in appearance. SUMMARY OF THE INVENTION It is an object of the present invention to provide a component assembly that makes it easy to identify burrs even if burrs are formed at the edges of the butted portions.

According to a first aspect of the present invention, there is provided a component assembly for a fishing reel, wherein at least a part of the surface is a three-dimensional curved surface, and a first surface component and a second surface component. And The first surface component is a molded component that forms a part of a three-dimensional curved surface. The second surface component is abutted with the first surface component, and the first surface component is formed on the three-dimensional curved surface.
It is a molded part that is arranged so that its surface is flush with the surface part. In the first surface component and the second surface component, the angle formed by the edge of the butted surface and each surface is:
The first surface component side has a range of 70 to 110 degrees, and the second surface component side has a range of 110 to 70 degrees. In this part assembly, the angle between the butted surface and each surface is 70 to 1
Since it is maintained at an angle of relatively close to 90 degrees of 10 degrees, burrs generated at the edge between the surface and the mating surface can be easily distinguished from the edge in any surface component. For this reason, even if burrs are formed, it is easy to remove only the burrs. A fishing reel component assembly according to a second aspect of the present invention is the assembly according to the first aspect, wherein the first surface component is a front cover also serving as a thumb rest disposed at a front portion of a reel body of the dual-bearing reel, The second surface component is a side cover arranged on the side opposite to the handle mounting side of the reel body. In this case, since the burr is easily removed, even if the finger touches the butted portion of the front cover also serving as the thumb rest and the side cover, it is difficult to feel a sense of incongruity. The component assembly for a fishing reel according to a third aspect of the present invention is the assembly according to the second aspect, wherein the first surface component is formed by a mold divided in a front-rear direction of the reel body, and the second surface component is a reel. It is molded by a mold divided in the left-right direction of the main body. In this case, it becomes easy to remove burrs of two surface parts formed using the molds divided in different directions. A fishing reel component assembly according to a fourth aspect of the present invention is the assembly according to any one of the first to third aspects, wherein both surface components are injection-molded synthetic resin molded products. In this case, it becomes easier to remove burrs from the synthetic resin molded product. A fishing reel component assembly according to a fifth aspect of the present invention is the assembly according to any one of the first to third aspects, wherein both surface components are die-cast metal molded products. In this case, it becomes easy to remove burrs of the metal molded product.

[Other embodiments]

(A) In the above embodiment, the reel body having the side cover and the front cover of the dual-bearing reel has been described as an example. However, the present invention is not limited to this, and for example, a component set such as a reel body of a spinning reel or a rotor. It can also be applied to solids. (B) In the above embodiment, a molded part assembly made of synthetic resin has been described as an example. However, the present invention can be applied to a metal part assembly molded by die casting, for example. .

According to the present invention, the angle between the abutting surface and each surface is maintained at an angle of 70 to 110 degrees, which is relatively close to 90 degrees. The burr generated at the edge of the edge becomes easy to distinguish from the edge. For this reason, even if burrs are formed, it is easy to remove only the burrs.
