Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a tow connector according to the present invention, and FIG. 2 is a side view showing a state in which the tow connector is connected to a motorcycle and a towed vehicle.

As shown in FIGS. 1 and 2, the traction connecting tool 1 includes a connecting tool body 2 formed of a pipe material in a substantially U-shape in a plan view, and the middle of the left and right arm portions 3 of the connecting tool body 2. It is composed of a pair of left and right auxiliary arms 4 which are raised and fixed to the upper side and a hitch ball 5 which is provided in a U-shaped bent portion of the connector body 2.

Attachment parts 6 are formed on the free end side of the arm part 3 of the connecting tool body 2 and on the free end side of the auxiliary arm 4, respectively. As shown in FIG.
It is attached to the vehicle body frame 8 of the motorcycle 7 with bolts 9 or the like.

On the other hand, a coupling coupler 12 is provided at the front end of the frame 11 of the towed vehicle 10.
The towed vehicle 10 is connected to the tow connector 1 by fitting the hitch ball 5 into the hitch ball 5 from above.

The rear part of the connector main body 2 of the traction connector 1 is bent and formed in a substantially L shape in a side view, and is formed in a crank shape as a whole. A fender 14 is disposed between the left and right arm portions 3 of the connector body 2 and between the attachment portion 6 to the motorcycle 7 and the hitch ball 5, and in the longitudinal portion 13 of the rear portion of the connector body 2. To be done.

As shown in FIG. 3, the fender 14 has, for example, a horizontal cross section curved in a U shape, and is a press-molded product of a metal plate or a synthetic resin molded product that has a human "nail" shape in appearance. Is. Further, the upper end thereof is bent inward to form a flange 15, and the flange 15 guides muddy water or the like applied to the inside of the fender 14 downward.

As a method of attaching the fender 14 to the connector body 2, for example, when the fender 14 is made of a weldable metal, as shown in FIG. The fender 14 may be welded to the inner surface of the. Further, as shown in FIG. 4B, if the boss portion 16 is formed on the inner side surface of the vertical portion 13, the fender 14 can be detachably fixed using the bolt 17 or the like regardless of the material.

By the way, when the fender 14 is fastened to the connector main body 2 with bolts 17 or the like, as shown in FIG. 3, a plurality of fastening holes 18, 19 are provided in the fender 14.
Need to be formed in the vertical direction, for example, in the upper and middle portions of the fender 14. In this case, the fastening hole 18 formed in the upper portion of the fender 14 is a circular hole, and the fastening hole 19 formed in the middle portion is a long hole. The fastening holes 19 may be all elongated holes, or the elongated holes may be loose fitting holes that are considerably larger than the bolt diameter.

When the fastening hole 18 formed in the upper portion of the fender 14 is a circular hole and the fastening hole 19 formed in the middle portion is a long hole, the fender 14 is centered on the upper bolt 17.
The lower part of can be adjusted in the front-rear direction, and a desired installation angle for the fender 14, θ1 and θ2 in FIG. 2, can be obtained. Further, when the fastening holes 19 are all elongated holes, the entire fender 14 can be adjusted in the front-rear direction.

As described above, between the left and right arm portions 3 of the connector main body 2 and between the attachment portion 6 to the motorcycle 7 and the hitch ball 5, the longitudinal portion of the rear part of the connector main body 2. By arranging the fender 14 at 13, the rear wheel 20 of the motorcycle 7 can be used even on a rainy day or when traveling on a water pool.
The splashed mud is guided to the road surface by the fender 14, so that the mud adheres to the hitchball 5 portion to reduce the function of the hitchball 5, or the towed vehicle 10 is scattered with mud or pebbles and is towed. The vehicle 10 and its cargo will not be contaminated or damaged.

Further, since the fender 14 can be easily attached to the connector body 2 and no modification of the vehicle body of the motorcycle 7 is required, the cost is not increased and the productivity and the maintainability are improved.

Further, since the rear portion of the connector main body 2 is bent and formed in a substantially L-shape in side view, when the fender 14 is fixed to the longitudinal portion 13 with bolts 17 or the like, a bracket for mounting the fender is not necessary. Therefore, there is no cost.

Of the fastening holes 18 and 19 formed in the fender 14, at least the fastening hole 19 arranged on the lower side is made long so that the position of the fender 14 can be adjusted. Even if the model of the motorcycle 7 to which the fender 14 is attached changes, the desired installation angle can be easily obtained.

[0024]

As described above, according to the two-wheeled vehicle traction connector structure of the present invention, the left and right arm portions formed by the pipe material in a substantially U shape in plan view are fixed to the vehicle body of the two-wheeled vehicle. And a hitch ball provided at a U-shaped bent portion of the connector body, wherein a traction connector for a motorcycle is provided between the left and right arm portions of the connector body. Moreover, since a fender is arranged between the attachment part to the vehicle body of the above two-wheeled vehicle and the hitch ball, and this fender is formed in a curved shape so that the central part thereof protrudes rearward, it is possible to drive on a rainy day or a water pool. Also, the dispersion of muddy water and the like on the tow connector and the towed vehicle is prevented.

Further, since the rear portion of the connector main body is bent and formed in a substantially L-shape in a side view, and the upper and middle portions of the fender are fixed to the longitudinal portion thereof with bolts or the like, the connector of the fender is therefore secured. Easy to attach to the body.

Further, a plurality of fastening holes are formed in the fender in the vertical direction to be fastened to the connector body with bolts or the like, while at least the lower side of the fastening holes is arranged. Since the fastening hole is a long hole, the mounting position of the fender can be easily adjusted.
