The present invention relates to a structure and a method for inserting a member into an insertion hole.
[0002]
[Prior art]
In vehicles such as motorcycles, various flexible elongate members such as electric wires for electric parts, wire cables for brakes or throttles, or hoses for oil and liquid are arranged. A connecting member such as a coupler is integrally provided at a tip portion of the vehicle. Wiring work or the like is performed in a state where the connecting member is integrally provided at the time of assembling a vehicle.
[0003]
In the wiring work as described above, when the electric wire 106 is inserted into a place where the two cover members 100 and 101 overlap as shown in FIG. 11, conventionally, the operation is performed with both the cover members 100 and 101 fixed. ing. Therefore, the insertion holes 102 and 103 formed in the cover members 100 and 101 are formed to have a size through which the coupler 105 can pass, and the overlapping area of both the insertion holes 102 and 103 also has a size through which the coupler 105 can pass. It is kept.
[0004]
[Problems to be solved by the invention]
As shown in FIG. 11, the overlap area between the insertion holes 102 and 103 of the adjacent cover members 100 and 101 is ensured to be large enough to allow the coupler 105 to pass therethrough. The structure and method for inserting the electric wire 106 provided with the following have the following problems.
[0005]
(1) After assembling, the electric wire 106 is located in the insertion holes 102 and 103. However, since the cross-sectional area of the electric wire 106 is smaller than that of the coupler 105, the gap between the insertion holes 102 and 103 and the electric wire 106 is small. The water and mud are likely to enter through the insertion holes 102 and 103. As a waterproof measure, a rubber grommet 110 is fitted into the insertion holes 102 and 103 after wiring as shown in FIG. However, when the grommet 110 is used, the number of parts increases, and the parts cost and work process also increase.
