  2. Description of the Related Art A vehicle having a structure capable of adjusting the light irradiation direction by a lamp such as a headlight mounted on the vehicle is known. For example, in an uneven terrain vehicle (hereinafter referred to as “ATV”) described in Japanese Patent No. 3466988, both ends of a headlamp are pivotally supported with respect to a lamp case so as to be rotatable in a vertical direction (vertical direction). The light irradiation direction of the headlamp can be adjusted by rotating an adjustment bolt from the rear of the case.

Further, in the motorcycle described in Japanese Patent Application Laid-Open No. 2002-370683, the aiming shaft mounting bracket that is locked by the aiming shaft at the rear outer periphery of the headlight is pivotally supported in the front-rear direction around the aiming shaft. Has been. And the light irradiation direction of a headlight can be adjusted up and down by rotating the aiming bolt attached to the back outer periphery lower part.
Japanese Patent No. 3466988 JP 2002-370683 A

  As described in the above publication, the aiming mechanism is configured to change the light irradiation direction by rotating the adjusting bolt. However, since a means for restricting the rotation end of the adjusting bolt is not provided, the nut screwed with the bolt may fall off due to the adjusting bolt being turned too much. Therefore, a simple structure that prevents this dropout has been expected.

  The objective of this invention is providing the light unit for vehicles which can perform fall prevention of the nut for aiming, and regulation of the adjustment range easily.

  In order to achieve the above object, the present invention provides a vehicle light unit comprising a lamp that is swingably supported with respect to a vehicle body frame and a cover member that covers the lamp, and a position deviated from the center of the swing. And a light irradiation direction adjusting bolt that is supported by the cover member and fits the nut, for example, below the lamp, and the tip of the adjusting bolt is on the vehicle body side. It is characterized in that it is arranged in the vicinity of the vehicle body components such as a clamper that holds the electric wiring together on the extension line.

  Further, the present invention is characterized in that the clamper is formed in a substantially U shape in plan view.

  According to the present invention having the above characteristics, the position of the nut is changed by turning the adjusting bolt, and the lamp supporting the nut is swung to change the light irradiation direction. When the nut is moved in the direction of the tip of the bolt, the nut abuts against the vehicle body component on the extension line of the adjustment bolt before dropping from the adjustment bolt, and the bolt is rotated so as to send the nut further. I can't let you. That is, the nut is prevented from falling off.

  In particular, prevention of the nut from falling off can be realized without increasing the number of parts by using body components having other functions and applications.

  Further, since the movement of the nut is restricted by a highly rigid member such as a clamper joined to the vehicle body frame, it is possible to reliably prevent the nut from falling. In particular, the clamper is formed in a substantially U shape and has increased rigidity.

  Further, since the nut is arranged near the lower side of the lamp, it is difficult to rain on the nut and the adjusting bolt screwed to the nut, and there is no concern about corrosion.

  An oil pan 35 is disposed below the engine 3, and a cooling fan 36 and a lubrication mechanism 37 that forcibly air-cool the engine 3 are disposed in front of the engine 3.

  An upper portion of the steering device 9 is provided with a meter cover 38 as a cover member that covers a light unit having an aiming mechanism, which will be described later, and in which a meter or the like is disposed to form a meter panel.

  FIG. 2 is a side view of the main part of the ATV 1 with the front part and the upper part of the meter cover removed, and FIG. 3 is a perspective view of the main part of the meter cover with the assist light unit removed. 4 is a side view of the main part of the steering unit, and FIG. 5 is a perspective view of the steering unit as viewed from the lower front side. In these drawings, a plate member 39 arranged substantially horizontally on the left and right of the vehicle body is provided at the upper end portion of the steering shaft 31. A handle 32 is supported on the plate member 39.

  A portion (front wall) 40 is vertically bent at the front portion of the plate member 39, and lower stays 41 and 41 for attaching a meter cover are coupled to the front surface of the front wall 40 by bolts and nuts 42, respectively. The lower stays 41, 41 are arranged separately on the left and right in the vehicle body width direction, and both ends of the pipe 43 are joined to the upper surface thereof by welding or the like. The pipe 43 extends outward from the lower stays 41 and 41 in the vehicle width direction, and then rises upward. A light holding plate 44 is joined to the middle of each rising portion (substantially vertical portion) of the pipe 43. An upper stay 45 is joined to the upper portion of the pipe 43, and a meter panel 47 is attached to the upper stay 45 by bolts and nuts 46.

  The light holding plate 44 has a pivot 48 extending inward in the vehicle body width direction. A bush 49 is attached to the outer periphery of the pivot 48, and the assist light 50 is rotatably held with respect to the pivot 48 via the bush 49. More specifically, a concave portion is formed on the outer side surface of the reflector 51 of the assist light 50 (having a reflection surface that reflects light from a light bulb provided on the inner side in front of the vehicle) so that the bushing 48 can be engaged therewith. (Described later) is formed, and the bushing 48 engages with the recess.

  The lower surface of the meter cover 38 is brought into contact with the lower stay 41 from below, and is fixed by a stopper 52 penetrating the meter cover 38 and the lower stay 41 in front of the attachment portion of the pipe 43 in the lower stay 41.

  A clamper 53 that holds a bundle (harness) of wires (not shown) wired to the meter panel 47 and the assist light 50 is joined to the plate member 39. The clamper 53 is substantially U-shaped in plan view. That is, it extends forward from the plate member 39 and bends in the vehicle width direction and further bends to the plate member 39 side. A portion surrounded by the U-shaped clamper 53 and the front wall 40 of the plate member 39 holds a harness extending vertically through this portion.

  The clamper 53 may be joined to the vehicle body frame, such as a top bridge, and may form an annular shape together with the plate member 39 so that the harness can pass therethrough. Therefore, it is not limited to the shape shown in FIG.

  Aiming bolts 54 that extend in the longitudinal direction of the vehicle body are attached to the lower portion of the meter cover 38. A nut holding portion 55 (FIG. 1) formed so as to protrude downward from the reflector 51 holds the nut 56 shown in FIG. 2 with its movement in the rotational direction being restricted, and the bolt 54 is screwed onto the nut 56. . The front horizontal portion of the clamper 53 is in the vehicle body side (vehicle body rear side) extending direction of the bolt 54 and is disposed close to the tip of the bolt 54. That is, when the bolt 54 is turned during the aiming operation and the nut 56 advances toward the tip of the bolt 54, the nut 56 is positioned at a position where it abuts. Specifically, the distance between the front end surface of the bolt 54 and the clamper 53 is set smaller than the height of the nut 56 (the axial dimension of the nut). This is because even if the nut 56 is fed out in the direction of the tip of the bolt 54, the nut 56 abuts on the horizontal portion of the clamper 53 before the nut 56 comes off the bolt 54.

6 is a front view of the assist light, FIG. 7 is a plan view, and FIG. 8 is a left side view. The assist light 50 includes a reflector 51, a lens 57 provided on the front surface of the reflector 51, a holding ring 58 provided on the rear part of the reflector 51, and a reflector 51 that is inserted into the reflector 51 from behind and is held by the holding ring 58. And a light bulb 59 (only the rear end is shown). The nut holding portion 55 provided on the lower surface of the reflector 51 is formed in a box shape with the rear opened, and holds the nut 56 so that the nut 56 does not rotate with the bolt 54 when the bolt 54 is screwed. be able to. A concave portion 60 adapted to the outer diameter of the bush 49 is formed on the side surface of the reflector 51 so that the bush 49 can be received. A hole 61 is formed in the nut holding portion 55 so that the bolt 54 can pass therethrough.

  FIG. 1 is a side view of an assist light unit including an aiming mechanism. In FIG. 1, the assist light 50 is supported on the meter cover 38 by the pivot 48 via the bush 49. A bolt 54 is inserted from the lower front portion of the meter cover 38, that is, from the front surface of the jaw portion 62, and the tip of the bolt 54 passes through the hole 61 of the nut holding portion 55. A coil spring 63 is disposed between the front inner side of the jaw 62 and the front surface of the nut holding portion 55 so as to act in the direction of widening the gap between the nut holding portion 55 and the jaw 62. The bolt 54 is screwed to the nut 56 held by the nut holding portion 55.

  In this aiming mechanism, when the bolt 54 is rotated clockwise from the front of the assist light 50 using a driver (not shown), the bolt 54 is fed into the nut 56, and the nut holding portion 55 holding the nut 56 is a coil spring 63. Is compressed and drawn to the position of 55a on the jaw 62 side. As a result, the assist light 50 rotates around the pivot 48 and the light irradiation direction of the assist light 50 changes upward.

  On the other hand, when the bolt 54 is turned counterclockwise, the nut 56 is fed back in the direction to be removed from the bolt 54, and the nut holding portion 55 holding the nut 56 is pushed by the coil spring 63 and is indicated by reference numeral 55b from the jaw 62 side. It is pulled away to the position. As a result, the assist light 50 rotates around the pivot 48 and the light irradiation direction of the assist light 50 changes downward.

  If the bolt 54 is continuously rotated so that the light irradiation direction of the assist light 50 is downward, the nut 56 eventually moves to the tip of the bolt 54, and the nut 56 contacts the horizontal portion 53 a of the clamper 53. At that position, the feeding of the bolt 54 is restricted. In this movement, the bolt 54 is a right-hand thread. Needless to say, if the bolt 54 is a left-hand thread, it moves in the opposite direction.

  In this way, the nut 56 abuts against the clamper 53 and the end of feeding of the bolt 54 is regulated by the clamper 53, so that the amount of change in the light irradiation direction is regulated, and the possibility that the nut 56 falls off the bolt 54 is avoided. Is done.

  By restricting the limit of the feed amount of the bolt 54 by the clamper 53, there is an advantage that it is not necessary to provide a dedicated feed amount regulating member. However, the member that regulates the feed amount of the bolt 54 is not limited to the clamper 53. For example, the bolt 54 is lengthened so that the front end of the bolt 54 can be disposed close to the front wall 40 of the plate member 39. Alternatively, the jaw part 62 and the net holding part 55 may be disposed so as to be displaced toward the plate member 39.

  In the present embodiment, an assist light having an aiming mechanism is shown as the light unit, but the scope of application of the present invention is not limited to this. It can be applied to various lighting devices (light units) such as headlights and fog lights installed in vehicles.
