Description

[0001]
BACKGROUND OF THE INVENTION
According to the present invention, the center portion of the bar handle is connected to the upper end portion of the handle post, and the handle grip switch is attached to the bar handle at a position adjacent to the inner end portion of the handle grip attached to the outer end portion of the handle post. The present invention relates to a small vehicle, and more particularly to improvement of a wiring structure in the vicinity of a bar handle of a lead wire connected to a handle grip switch.
[0002]
[Prior art]
In wiring the lead wire in the vicinity of the bar handle in a motorcycle, the lead wire along the outer surface of the bar handle is attached to the bar handle with a band, or as disclosed in JP 2000-128056 A, 2. Description of the Related Art Conventionally known is a rivet welded to a bar handle that engages and holds a clamp that holds a lead wire disposed along the outer surface of the bar handle.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned conventional one, the lead wire is disposed so as to be exposed on the outer surface of the bar handle, so it is difficult to say that the appearance is excellent. Therefore, the lead wire is inserted into the bar handle, and the lead wire led out from the outlet hole provided in the side wall of the bar handle at the portion corresponding to the handle grip switch may be connected to the handle grip switch. In such a structure, it is necessary to consider the strength of the bar handle by providing the lead-out hole, and a structure that ensures waterproofness in the lead-out hole is required.
[0004]
In view of such circumstances, the present invention is a compact size that improves the appearance by securing the strength of the bar handle and eliminating the need for a special waterproof structure and arranging the lead wires so as not to be exposed to the outside of the bar handle. A first object is to provide a bar handle wiring structure in a vehicle.
[0005]
By the way, when inserting the lead wire into the bar handle, a part of the bar handle is formed into a box shape that can be opened and closed, and the lead wire can be easily inserted into the bar handle (for example, Japanese Patent Laid-Open No. 3-21582). However, in such a case, the structure of the bar handle is complicated.
[0006]
In view of such circumstances, the present invention provides a bar handle wiring structure in a small vehicle that can facilitate the operation of inserting a lead wire into the bar handle while avoiding a complicated structure of the bar handle. The second purpose is to provide it.
[0007]
[Means for Solving the Problems]
In order to achieve the first object, the invention according to claim 1 is characterized in that the center portion of the bar handle is connected to the upper end portion of the handle post and the inner end of the handle grip attached to the outer end portion of the bar handle. In a small vehicle in which a handlebar grip switch is attached to the bar handle at a position adjacent to the portion, a lead wire inserted into the bar handle is led out from an outer end portion of the bar handle and connected to the handlebar grip switch, The lead wire is covered with a handle grip between an outer end portion of a bar handle and the handle grip switch.
[0008]
According to such a configuration of the first aspect of the present invention, the lead wire is inserted into the bar handle, and a portion of the lead wire that is led out from the outer end portion of the bar handle and connected to the handle grip switch. Since the lead wire is covered with the handle grip, the lead wire can be arranged so as not to be exposed to the outside of the bar handle to improve the appearance, and the lead hole for leading the lead wire is provided in the side wall portion of the bar handle. Therefore, the strength of the bar handle can be ensured, and a special waterproof structure is not required by covering the lead wire from the outer end of the bar handle to the handle grip switch with the handle grip.
[0009]
In order to achieve the second object, according to a second aspect of the present invention, in addition to the structure of the first aspect of the invention, the lead wire is inserted into the bar handle through the handle post. An operation hole for inserting the lead wire into the bar handle is provided at an upper end of the handle post so as to face upward at a central portion of the bar handle.
[0010]
According to the configuration of the invention described in claim 2, when inserting the lead wire into the bar handle through the handle post in order to enhance the appearance, the handle post is arranged so as to face upward at the center of the bar handle. Since the lead wire can be inserted and operated from the operation hole provided at the upper end, it is possible to facilitate the insertion operation of the lead wire into the bar handle while preventing the bar handle from having a complicated structure. .
[0011]
Furthermore, the invention according to claim 3 is characterized in that, in addition to the configuration of the invention according to claim 2, the operation hole is covered with an auxiliary machine, and according to this configuration, the operation hole is closed with an auxiliary machine. As a result, the appearance can be improved and the waterproofness can be improved by preventing water from entering the operation hole.
