Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention includes a straddle-type driving seat on a vehicle body frame extending between a pair of left and right rear wheels, and a straddle-type driving seat on the body frame. The present invention relates to a rear fender support structure for an uneven terrain vehicle, which is provided with a pair of left and right rear fenders protruding laterally from between a body frame and a driving seat.

(Background of the Invention) A straddle-type driving seat is provided on a body frame that extends forward from between a pair of left and right rear wheels, and a pair of left and right rear fenders that project laterally from between the body frame and the driving seat are attached. There are leveling vehicles.

In this case, since the rear fender has a cantilevered structure, there is a problem that the rear fender is likely to vibrate up and down when traveling on rough ground.

In order to prevent such vibration of the rear fender, for example, as shown in Japanese Utility Model Laid-Open No. 58-122673, a carrier wider than the body frame is attached to the body frame to face the rear fender while the rear fender is exposed. There is proposed a structure in which a stay extending to the lower part of the vehicle body is bound to a vehicle body frame, and a rear fender is sandwiched between the carrier and the tip of the stay to bind them together. However, in this structure, the carrier and the stay support the vicinity of the center of the rear fender, so that the vibration isolation of the rear portion of the rear fender is insufficient. Therefore, especially when a relatively heavy rubber flap is attached to the outer edge of the rear part of the rear fender, the vibration of the rear fender cannot be sufficiently prevented, and the flap may interfere with the rear wheels when traveling on rough terrain. However, there is a problem that the rear fender or the flap may be damaged by being caught in the rear wheel in some cases.

(Object of the invention) The present invention has been made in view of such circumstances, and can sufficiently prevent the vibration of the rear fender, and even when the flap is attached to the rear edge of the rear fender, the rear fender and the flap and the rear wheel are It is an object of the present invention to provide a rear fender support structure capable of reliably preventing vehicle interference and having a very simple structure.

(Structure of the Invention) According to the present invention, an object of the present invention is to provide a body frame extending forward between a pair of left and right rear wheels, a straddle-type driving seat provided on the body frame, a body frame and a driving seat. In a vehicle for rough terrain traveling, which includes a pair of left and right rear fenders that project laterally from the space to the front and above each rear wheel to the vicinity of the rear edge of the rear wheel, the rear fenders are integrally formed with a connecting portion that connects them. A notch is formed in the connecting portion and opened rearward, and a rear bumper extending obliquely upward and rearward from the notch is fixed to the vehicle body frame, and the rear bumper is provided near the rear edges of both rear fenders. A pair of left and right stays projecting laterally along the lower surface of the rear fender is fixed, and the rear fender supporting structure is fixed to the stay near the rear edge of each of the rear fenders. Is made.

Reference numerals 2 and 12 denote a pair of left and right steering front wheels, to which wide ultra-low pressure tires (so-called balloon tires) are mounted. Reference numeral 14 denotes a vehicle body frame, which extends forward from the left and right rear wheels 10, 10 and has front wheels 12, 12 at the front thereof.
Is attached. As shown in FIG. 2, the body frame 14 includes a main tube 16, a front tube 18, a neutral tube 20, a pair of left and right lower tubes 22 (only one is shown), a pair of left and right seat pillar tubes 24 (only one is shown), left and right. A pair of seat rails 26, 26, rear tubes 28, 30 (only one of each is shown), and the like are provided. A rear bumper 32 having substantially the same width as the seat rail 26 is fixed to the rear portion of the seat rail 26. Rear wheels 10,10
Is held by a rear arm 34 whose front end is vertically swingably connected to the body frame 14. The rear wheel 10 can move up and down by expanding and contracting a pair of left and right shock absorbers 36 (only one is shown).

In FIG. 2, 38 is an engine mounted near the center of the vehicle body, 4
Reference numeral 0 is a carburetor, and reference numerals 42 and 44 are front and rear air cleaners and packing boxes disposed between the left and right seat rails 26. The intake air of the engine 38 enters the main tube 16 from an intake port (not shown) that opens at the front of the main tube 16, is guided to the air cleaner 42 through the main tube 16, and further passes through the carburetor 40 to the engine 38. Inhaled. The luggage box 42 can be opened from the rear. In FIG. 2, 46 is a steering handle, 48 is a fuel tank, and 50 is a body frame 14.
A straddle-type driving seat provided above, and 52 are front fenders integrally formed on the left and right sides so as to cover the upper portions of the left and right front wheels 12.

Reference numerals 54 and 54 are a pair of left and right rear fenders that project laterally from between the vehicle body frame 14 and the driving seat 50, and these are integrally molded together with a connecting portion 56 by a synthetic resin. The front portion of the rear fender 54 is largely curved so as to cover the front of the rear wheel 10, and the rear portion is substantially flat so as to cover the upper portion of the rear wheel. The outer edge of the rear fender 54 is bent obliquely downward. Further, from the rear side edge to the rear edge of the rear fender 54, soft rubber flaps 58, 58 are formed.
Is attached.

The front portions of the rear fenders 54, 54 are fixed to the brackets 60, 60 protruding laterally from the lower tube 22 with screws as shown in FIGS. Rear fender 5
The vicinity of the center of 4, 54 is screwed to brackets 62, 62 and 64, 64 fixed to the left and right seat rails 26, 26. The rear bumper 32 extends rearward through the inside of the rear edges of the rear fenders 54, 54, and the rear bumper 32 has stays 66, 66 protruding laterally along the rear lower surface of the rear fenders 54, 54. Is stuck. A cutout portion that opens rearward is formed in the connection portion 56 of the rear fenders 54, 54, and the rear bumper 32 projects obliquely rearward and upward from the cutout portion. For this reason, both stays 66, 66 are left and right rear fenders 54, 5 from the notch.

Since the stay 66 is provided so as to project along the lower surface of the rear edge portion of the rear fender 54, there is no gap between the stay 66 and the rear fender 54, and grass or the like that the rear wheel 10 winds up does not easily wind around the stay 66. You can also get the effect. The present invention also includes a rear wheel that cannot move up and down with respect to the vehicle body frame without a shock absorber, but since the stay is located above the rear portion of the rear wheel, the shock absorber is provided to remove the rear wheel. Even when it is configured to be vertically movable, the tire does not interfere with the stay at the time of full bumping of the rear wheel, and there is no fear of damaging the tire.

As described above, according to the present invention, since the stay protruding laterally is fixed to the rear part of the vehicle body frame and the rear part of the rear fender is fixed to this stay, the vibration is applied to the rear part of the rear fender with a simple structure. Can be reliably prevented. Therefore, even when a flap or the like is attached to the rear edge of the rear fender, the rear fender and the flap do not interfere with the rear wheel due to vibration. In addition, a cutout that opens rearward is provided at the connection part of the rear fender, and the rear bumper is extended rearward from this cutout, so that the stay can be easily installed from the left and right side edges of the cutout along the lower surface of the rear fender. It can be provided and the structure is very simple.
