DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting components such as electric components and engine components of a motorcycle to a vehicle body.

[0002]

2. Description of the Related Art Conventionally, an upper component reinforcing plate and a lower component reinforcing plate are fixed to a branch portion of a main frame which branches right and left from a head pipe and extends rearward to form an electrical component storage room therebetween. An example in which the bracket is fixed to the bracket with bolts and the electrical components are concentrated and arranged on the bracket (Japanese Utility Model 5-99)
No. 93). In addition, there is an example in which a coupler box is fastened and fixed to a stay fixed to a head pipe by bolts, and a coupler terminal and a fuse box are stored and held in the coupler box (Japanese Utility Model Publication No. 3-703).

[0003]

As described above, in the conventional component mounting apparatus, the brackets and boxes for mounting and supporting components such as auxiliary machines are fixed to the vehicle body such as the main frame and the head pipe by bolts or the like. The number of parts is increased due to bolts and the like, and tools are required for assembling, so that there are cases where workability is poor.

The components supported by one support such as a bracket are usually one component, and are limited to several types of electrical components even when they are arranged in a concentrated manner as in the example described in the above-mentioned publication. Engine parts such as the chamber are fixed separately by stays, and the wire harness etc. will also be supported by the guide member, and the number of parts will increase more and more, and since they are supported by different support tools, they will interfere with each other. In order to avoid this, it is necessary to secure a certain distance between each other, and due to the interference prevention space, efficient arrangement of components cannot be achieved.

[0005] The present invention has been made in view of such a point,
The object of the present invention is to provide a motorcycle component mounting structure which has a small number of components, is excellent in workability, and can effectively utilize space.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a resin component mounting member integrally molded so as to be capable of fitting and supporting a plurality of types of components. together are bridged supported between a pair of main frames extending rearwardly, the component attachment member has an engagement piece, the main engagement piece is elastically deformed
A component mounting structure for a motorcycle that is fixed by engaging with the frame .

[0007] Since the component mounting member is supported by being fitted into a pair of main frames by utilizing the elasticity of the engagement piece , the component mounting member does not require mounting bolts and can be easily mounted on the vehicle body without mounting tools. It can be fixed and has excellent workability. In addition, since the integrally formed one-part mounting member can fit and support a plurality of types of parts without tightening bolts or the like, a space for preventing interference between the parts is not required, and a space for arranging parts is reduced. It can be used effectively and more parts can be efficiently arranged.
