Ru.

"Embodiment" Hereinafter, one embodiment of the present invention will be described in detail using FIGS. 2 to 8.

FIG. 2 is an overall side view of a motorized bicycle to which the front fender mounting structure of this embodiment is applied.
Reference numeral 8 is a handle pipe, 9 is a front fork, 10 is a front fender, and 11 is a frame body.

The surroundings of the front fork 9 are shown in FIGS. 3 and 4. The front fork 9 includes a steering stem 12 and an inverted U-shaped pipe member 1 connected to the lower end of the steering stem 12.
It consists of 3. One end of bottom links 16, 16 is fixed to the lower ends of both side pipe parts 14, 14 of this pipe member 13 via brackets 15, 15, respectively.
A front wheel 17 (see FIG. 2) is pivotally supported between the other ends of the wheels 6 and 16.

Further, U-shaped cushion brackets 18, 18 are attached to the front fender 1 on the upper side surfaces of the side pipe portions 14, 14 on the vehicle seat side, respectively.
It is attached so as to be in contact with the lower edge of 0.
One end portion of a cylindrical cushion 19, 19 is inserted into the cushion brackets 18, 18, respectively, and is rotatably connected. The other end of the cushion 19 is connected to the center of the bottom link 16, thereby forming a front wheel suspension.

A gusset 20 is welded between the pipe member 13 and the upper surface of the front fender 10 to close the gap between them and serve as reinforcement.

The front fender 10 is made of elastic synthetic resin and is molded to a constant thickness. As shown in FIG. 5 (top view), this front fender 10 has different widths at the front and back at the position where the side pipe parts 14, 14 are fitted, and the front part (left side in the figure) has two side pipes. The distance between the portions 14 and 14 is approximately equal to 〓. On the other hand, in the rear part of the front fender 10 (on the right side), bulging parts (locked parts) 21, 21 that protrude to both sides are formed, and the side pipe parts 14, 1 are larger than the front part.
It is about the thickness of 4, and is widened on both sides. As a result, each of the bulging portions 21, 21 is connected to the side pipe portion 1, respectively, as shown in FIG. 7 and FIG.

8 and 18 to prevent downward movement.

Further, protrusions 22, 22 are formed at the lower portions of both side surfaces of the front portion of the front fender 10, respectively, to abut the side surfaces of the side pipe portions 14, 14. The contact surfaces of these protrusions 22 with the side pipe section 14 are shaped to correspond to the circumferential surface of the side pipe section 14 . The front fender 10 is positioned back and forth by inserting and locking the side pipe portion 14 between the protruding portions 22 and the bulging portion 21. In addition, these protruding parts 22, 22 can pass between the side pipe parts 14, 14 by bending the fender 10 and contracting it in the width direction.

Furthermore, as shown in FIG. 6, a stopper projection 23 is provided on the upper surface of the front portion (left side in the figure) of the front fender 10 at a position facing the gusset 20.
is formed so that its tip abuts against the front surface of the gusset 20. This stopper protrusion 23
This is to prevent the front fender 10 from rotating around the portion P that is locked to the cushion bracket 18, and from lowering the rear portion, which is heavier than the front portion.

Further, two mounting holes 25, 25 are formed in the front fender 10 at the rear of the stopper projection 23, and as shown in FIG. It is fixed at 13.

Next, a procedure for attaching the front fender 10 in the above-mentioned attachment structure will be explained.

First, the front fender 10 is bent to narrow the width between the protrusions 22, 22 on both sides, and the front fork 9 is loaded between the side pipes 14, 14 from the seat side in a slightly forwardly inclined state. . Then,
When the tilted front part is lifted and adjusted to a predetermined angle, and the bending force is removed, the protrusions 22, 2
2 engages with the side pipe portions 14, 14, and at the same time, the bulging portions (locked portions) 21, 21 engage with the cushion brackets (locking portions) 18, 18.
Further, the stopper protrusion 23 engages with the gusset 20 and locks the fender 10 so that it does not rotate about the cushion bracket 18 as a fulcrum. In this way, the front fender 10 is supported between the side pipe parts 14, 14, and the bolts 24,
24 to complete the fender installation.

With the front fender mounting structure having such a configuration, the front fender 10 can be attached by simply fitting the front fender 10 into the predetermined position as described above.
0 is fixed so that it does not move, so subsequent bolt tightening work can be performed without having to support it by hand as in the conventional case. Further, the cushion brackets 18, 18 and the gusset 20 are provided in advance on the front fork 9, and the bulges 21, 21 and the stopper protrusion 23 formed on the front fender 10 are engaged with or brought into contact with them. There is no need to attach a new member or the like for engaging the front fender 10 to the front fork 9. Since the cushion brackets 18, 18 and the gusset 20 are also used as members for engaging the bulges 21, 21, respectively, and as members for contacting the stopper protrusion 23, the structure can be simplified and the number of parts can be reduced. Not only can processing time be reduced, but costs can also be kept down.

In addition, in this embodiment, both side pipes 14, 1
Since the front fender 10 can be installed in a predetermined position by inserting the front fender 10 from the side between the side pipes 4 and 4, the front fender 9 does not have to be moved, compared to the conventional installation structure in which the front fender 10 had to be fitted from the lower end of the side pipe and moved upward. This has the advantage that the fender 10 can be attached without any problems. And in the installed state,
The front fender 10 is prevented from moving downward, and has two points of the bulges 21, 21 relative to the cushion brackets 18, 18, and a stopper protrusion 23.
With one point supported on the gusset 20 of
It is stably positioned and supported between the side pipe parts 14, 14.

Therefore, with the front fender mounting structure of this embodiment, the work of mounting the front fender 10 is extremely easy for the reasons mentioned above.
It has the advantage of improving work speed, increasing productivity, and making it suitable for mass production.

``Effect of the invention'' In the front fender mounting structure of the invention, one end of the cushion that pivots the front wheel and constitutes the front wheel suspension is attached via a cushion bracket, and a reinforcing gusset is attached to the upper part of the cushion. In a front fender mounting structure in which a front fender is placed and fixed between both side pipes of a fixed front fork, locking locks are formed on both sides of the front fender to prevent downward displacement. The front fender is positioned and installed with respect to both side pipe parts by engaging the front fender with the cushion bracket and bringing the stopper protrusion formed on the upper surface of the front fender into contact with the front surface of the gusset. When installing the front fender, just by fitting the front fender into the front fork, the front fender is temporarily supported stably at three points, making it possible to attach the front fender as usual. Since the subsequent bolt tightening work can be done without having to hold it down by hand, the front fender installation work can be done quickly and productivity can be increased. In addition, since the structure is such that the cushion bracket and gusset that are previously provided on the front fork engage or come into contact with the locked portion and stopper protrusion formed on the front fender, it is also possible to add new parts to the front fork. There is no need to attach it, simplifying the structure, reducing the number of parts and processing time, and reducing costs.
