Description

  The present invention relates to an improvement in a saddle riding type vehicle in which a harness guide is provided at a front portion of a vehicle body.

  A straddle-type vehicle is known in which a harness guide for holding a harness extending from a headlight, a harness extending from left and right turn signals, and the like is provided at a front portion of a vehicle body (for example, Patent Document 1 (FIG. 1 11).

  In FIG. 11 of Patent Document 1, the stay (76) is attached to the bottom bridge (73) and the top bridge (74) of the front fork (72) (the numbers in parentheses indicate the symbols described in Patent Document 1. The same applies hereinafter). A front cowl (79) that supports the headlight (18) and the left and right turn signals (97) and covers the front of the vehicle is attached to the stay (76).

  A harness (63) extends rearward from the headlight (18) and a harness (119) extends rearward from the winker (97). The harness (63, 119) includes a stay (76) and a bottom bridge. It is held by the harness guide member (120) attached to (73).

  However, in the technique of Patent Document 1, the harness guide member (120) is a separate member and is fastened to the bottom bridge (73), so the number of parts increases. In addition, since the harness guide member (120) is fastened to the stay (76) and the bottom bridge (73), the assembly man-hour may increase, and there is room for improvement in productivity.

JP 2008-105665 A

  An object of the present invention is to provide a straddle-type vehicle that makes it possible to increase productivity related to assembly without increasing the number of parts.

In a straddle-type vehicle equipped with a headlight mounted on a mechanism and disposed in front of a head pipe, and a front cowl disposed around the headlight and fixed to a steering mechanism, the front cowl A harness guide that extends from the rear portion of the headlight to the vehicle body frame and guides the harness is integrally formed at the lower portion of the headlight. The harness guide extends below the head pipe and is inserted into the lower portion of the steering mechanism for steering. It is characterized by having an insertion part fixed to the mechanism.

  In the invention according to claim 2, the harness guide is formed in a U shape whose cross section in the vehicle width direction opens upward, and the lower surface of the harness guide has a cross section in the vehicle width direction formed in a straight line. When the vehicle is viewed from the side, the vehicle extends obliquely downward toward the rear of the vehicle.

  In the invention according to claim 3, the steering mechanism includes a steering handle that is steered by the driver, a steering stem that is steered by the steering handle and is rotatably supported by the head pipe, and a bottom that is fixed below the steering stem. The harness guide is disposed so as to cover the steering stem when the vehicle is looked up from below.

  In the invention according to claim 4, the engine is disposed behind and below the head pipe from the head pipe, and the engine is attached to the vehicle body frame. When the engine is viewed from the front, the engine is positioned lower than the lower end of the harness guide. It is characterized by being arranged exposed below.

  The invention according to claim 5 is characterized in that an opening through which the harness passes is formed at the rear end of the harness guide, and one insertion part is formed on each side of the opening in the vehicle width direction. .

  According to the sixth aspect of the present invention, an insertion receiving portion into which the tip of the insertion portion of the harness guide is inserted is formed in the lower portion of the steering mechanism, and when the vehicle is looked up from below, the insertion portion of the harness guide is Formed in a C shape narrowed toward the front, formed in a C shape narrowed at the tip of the insertion part toward the rear of the vehicle, and narrowed in the insertion receiving part toward the rear of the vehicle It is formed in a letter shape.

In the invention according to claim 1, a harness guide that extends from the rear portion of the headlight and guides the harness is integrally formed at the lower portion of the front cowl.
If the harness guide is separately provided in the form of another part, the number of parts increases. In the present invention, the harness guide is integrally formed with the front cowl. That is, it is not necessary to make the harness guide in the form of another part, and an increase in the number of parts can be suppressed. In addition, when the front cowl is assembled to the operation mechanism, the insertion portion is assembled to the steering mechanism, so that productivity related to assembly can be improved.
Therefore, according to the present invention, it is possible to reduce the number of parts and increase the productivity related to assembly.

  The traveling wind that flows under the front cowl and under the steering mechanism is guided by a harness guide whose lower surface is linearly formed in the vehicle width direction and extends obliquely rearward. Can be increased.

  In the invention according to claim 3, since the harness guide is disposed so as to cover the steering stem when the vehicle is looked up from below, foreign matter such as dust enters the steering stem as the pivot shaft. Can be suppressed.

  In the invention according to claim 4, the engine is disposed behind and below the head pipe, and the engine is disposed so as to be exposed below the lower end of the harness guide when the vehicle is viewed from the front. The traveling wind flows backward along a harness guide that extends obliquely downward toward the rear of the vehicle and is guided to the engine, so that the cooling performance of the engine can be improved.

  In the invention which concerns on Claim 5, since the insertion part is formed in the vehicle width direction both sides of the opening part which lets a harness pass, an insertion part will be provided in a site | part different from an opening part. It can avoid that the harness which passes to a part interferes with an insertion part.

  In the invention which concerns on Claim 6, it forms in the cross-section shape which narrowed the front-end | tip of the insertion part provided in the harness guide toward the vehicle rear, and the cross-section shape which narrowed the insertion receiving part toward the vehicle rear. Therefore, there is no worry that the insertion part and the harness interfere with each other. Even if the insertion portion is enlarged, it is possible to increase the support strength of the harness guide without causing interference between the insertion portion and the harness.
