Description

  The present invention relates to an improvement of a motorcycle including an aiming operation unit that adjusts an optical axis of a headlight.

The motorcycle is provided with a headlight at the front of the vehicle. The headlight is provided with an aiming operation unit for adjusting the optical axis.
As described above, various motorcycles including an aiming operation unit have been proposed (see, for example, Patent Document 1 (FIGS. 1, 9, and 10)).

  As shown in FIG. 9 of Patent Document 1, in a motorcycle headlight, a reflector (40) that reflects irradiated light toward the front of the vehicle (the numbers in parentheses indicate the symbols described in Patent Document 1). The same shall apply hereinafter) is pivotally supported by the housing (41) by the pivot portion (50a).

As shown in FIG. 10 of Patent Document 1, the aiming bolt (51) is inserted into the coupling portion (41e) of the housing from the rear of the vehicle and screwed into the nut (52) fixed to the coupling portion (40b). ing.
A connection part (40b) is a member which connects a pair of reflectors. When the aiming bolt (51) is rotated, the connecting portion (40b) moves back and forth in the vehicle. Then, the reflector (40) shown in FIG. 9 of Patent Document 1 swings around the pivot portion (50a), and the optical axis is adjusted.

Although there is no description in Patent Document 1, since there is a leg shield behind the vehicle of the aiming bolt (51) and it is difficult to insert the tool, the tool is inserted upward from below.
There is a front fender below the aiming bolt (51). However, in consideration of the operation of the tool, workability increases as the distance between the aiming bolt (51) and the front fender increases.
Therefore, the front fender (22) and the front cowl (14) shown in FIG. 1 of Patent Document 1 are separated from each other.

  On the other hand, it is desired to shorten the distance between the front fender and the front cowl as much as possible, to make the front part of the vehicle compact and to improve the mobility by continuous air flow between the front fender and the front cowl. That is, there is a need for a motorcycle that can secure the workability of the optical axis adjustment and can reduce the distance between the front fender and the front cowl so that the front portion of the vehicle can be made compact.

JP 2008-198466 A

  It is an object of the present invention to provide a motorcycle capable of ensuring the workability of optical axis adjustment and reducing the distance between the front fender and the front cowl so that the front portion of the vehicle can be made compact.

  The invention according to claim 1 is a front fender that covers an upper portion of a front wheel, a head pipe that is provided at a front portion of a vehicle body frame and pivotally supports the front wheel, and is disposed above the front fender. In a motorcycle including a front cowl to cover, a headlight disposed on the front surface of the front cowl, and an aiming operation unit that adjusts the optical axis of the headlight, on the top of the front fender in a side view, A concave portion which is depressed downward is formed, and the bottom of the concave portion is a flat portion extending forward of the vehicle, and the aiming operation portion is disposed so as to face the flat portion.

  In the invention according to claim 2, the aiming operating portion is fixed to the head pipe and supports a headlight from the lower side, and the lower support member is provided with the longitudinal direction extending in the traveling direction of the vehicle. And a fastening member that is inserted through the long hole and fastens the headlight and the lower support member.

  In the invention which concerns on Claim 3, a fastening member is the volt | bolt arrange | positioned so that the axis and flat part of this fastening member may cross | intersect, It is characterized by the above-mentioned.

  In the invention according to claim 4, the lower support member includes a support stay provided on the head pipe, and an under cowl that is fastened to the front cowl and bulges downward so as to face the recess in a side view. Features.

  The invention according to claim 5 is characterized in that the under cowl is supported by being inserted into a support stay.

  The invention according to claim 6 is characterized in that the aiming operation portion is provided at two locations away from the center in the vehicle width direction.

  The invention according to claim 7 is characterized in that the front cowl includes a leg shield that covers at least a part of the aiming operation portion in a side view.

In the first aspect of the invention, a concave portion that is depressed downward is formed in the upper portion of the front fender, and the bottom of the concave portion is a flat portion that extends forward of the vehicle, and the aiming operation portion is disposed so as to face the flat portion. .
The aiming operation can be performed through a recess in the upper part of the front fender. Furthermore, since the recess extends forward of the vehicle, the aiming operation can be performed from the front of the vehicle.

Therefore, in the present invention, the front fender and the headlight can be arranged close to each other, the distance between the front cowl and the front fender covering the headlight can be shortened, and the size reduction can be achieved.
That is, it is possible to ensure the workability of the optical axis adjustment and shorten the distance between the front fender and the front cowl.

Since the front fender and the front cowl are arranged close to each other, it is possible to improve the mobility due to the continuous air flow between the front fender and the front cowl.
Further, the exposure of the aiming operation unit can be suppressed and the appearance can be improved.

In the invention according to claim 2, since the aiming operation portion also serves to fix the headlight, the number of parts can be reduced and the cost can be reduced.
In addition, since the headlight is supported from below by the lower support member fixed to the head pipe, the fixing of the headlight can be strengthened and a large-sized headlight can be supported.

  In the invention according to claim 3, since the fastening member is a bolt arranged so that the axis of the fastening member and the flat portion intersect each other, a tool is passed between the front fender and the front cowl to rotate the bolt. The gap between the front fender and the front cowl can be shortened as long as there is a gap for the tool to enter in parallel with the flat portion.

  In the invention according to claim 4, the lower support member includes an under cowl that is fastened to the front cowl and bulges downward so as to face the recess in a side view. Since the under cowl is arranged in the space of the concave portion of the front fender and the headlight is brought close to the front fender, the center of gravity can be lowered by lowering the position of the heavy headlight, and the exercise performance can be improved.

  In the invention which concerns on Claim 5, the under cowl is inserted and supported by the support stay. Since the lower support member is sub-assembled to the front cowl and then inserted into the vehicle body side and assembled, productivity can be improved.

  In the invention which concerns on Claim 6, the aiming operation part is provided in two places away from the center of the vehicle width direction outward. By steering the front wheels to the left and right, the aiming operation unit located in the opposite direction to the steered direction is separated from the front fender, so that a work space can be secured and workability can be further improved.

  In the invention which concerns on Claim 7, the front cowl is provided with the leg shield which covers at least one part of an aiming operation part by side view. Since the exposure of the aiming operation unit is suppressed, the appearance can be improved.
