し、エンジンが始動できなくなることがある。(Background of the invention) In motorcycles and vehicles for traveling on rough terrain, the engine is usually mounted near the center of the vehicle body, and a fuel tank is arranged to cover the top of the engine.
In recent years, fuel tanks made of synthetic resin have come into widespread use. This synthetic resin fuel tank has a smooth surface around the entire circumference, unlike sheet metal fuel tanks, which are formed in the shape of a flange where the upper plate and inner plate are attached to the lower surface and stand up downward. Therefore, during rainy weather, raindrops on the top or sides of the tank may flow down the tank surface, wrap around the bottom of the tank, and drip onto the engine spark plug. For this reason, if you park your car in the rain,
When starting the engine, current from the spark plug may leak and cause a misfire, making it impossible to start the engine.

設けられる。 The fuel tank 32 is formed by blow molding. This tank 32 is mounted so as to straddle the main tube 18, and a mounting ring 40 protruding from the lower surface thereof,
40 is attached to the neutral tube 24 via annular rubber dampers 42, 42. Also tank 3
2 is placed on a bracket 44 fixed to the main tube 18 via a rubber damper 46, and is further attached to this bracket 44 by a rubber band 48 (see FIG. 2). This tank 32 is made so as to straddle the main tube 18, and a convex strip is formed on the lower surface of one of the distribution parts 32a, 32b along the longitudinal direction (front and rear direction) of the tank 32. This longitudinally long protruding strip 50 is located on the outside (on the right side in FIG. 3) of the spark plug 38 of the engine 36, and its front end is long in the vehicle width direction located forward of the spark plug 38. The protrusion 50A is continuous with the outer end of the vehicle body. Here, on the lower surface of the distribution portion 32b of the tank 32, the front side of the ignition plug 38 is higher than the rear side thereof, and the protruding strip 50A is provided on this higher side.
従つて、雨中停車時に雨滴がタンク３２の側面

の点火栓３８が水びたしになることがなくなる。 Therefore, even if raindrops flow down the side surface of the tank 32 and wrap around the lower surface of the distribution part 32b when the vehicle is stopped in the rain, the raindrops will drip from the ridge 50 without going around inside the ridge 50. In addition, raindrops that flow on the front surface of the tank 32 and wrap around the lower surface of the distribution part 32b are blocked by the protruding strip 50A that is long in the width direction of the vehicle body, and then drip from the protruding strip 50A, so that the raindrops drip from the protruding strip 50A, so that they fall above the ignition plug 38 behind the protruding strip 50A. does not flow. For this reason, engine 36
This prevents the ignition plug 38 from becoming soaked with water.

This is a top cover that covers the steering shaft 26 and the front tubes 20, 20. The top cover 56 has a pair of left and right running air intakes 58, 58, and the air taken in from these is guided to the inner bottom surface of the fuel tank 32 to cool the engine 36 (see FIG. 2). Further, in FIG. 1, 60 is a front fender, 62 is a rear fender, and 64 is a cargo platform.

Although it was provided only in one distribution section 32b of 2,
When using an engine having spark plugs on both the left and right sides, such as a cylinder engine, it goes without saying that protrusions may be provided on both distribution portions. Further, in this embodiment, the protruding strip 50 is formed integrally with the tank 32, but a protruding strip member (for example, edge rubber) may be attached separately from the tank 32. The protrusion is not on the bottom of the tank,
It may also be provided at the bottom of the side of the tank.

クによりエンジンが失火するおそれがない。(Effects of the invention) As described above, the present invention provides a longitudinally long protrusion 50 located outward from directly above the ignition plug of the engine on the lower surface or lower side of the fuel tank disposed above the engine. A long protruding strip 50A in the vehicle width direction is provided on the higher side of the lower surface of the tank located forward or rearward of the spark plug, and the outer end of the protruding strip 50A long in the vehicle width direction is a longitudinally long protrusion. This is a continuation of Article 50. For this reason, raindrops flowing down the side of the tank have long protruding lines 5 in the front and back.
Raindrops that are caught by the raindrops and drip down the tank front or rear surface on the higher side of the tank lower surface are caught by the protrusions 50A that are long in the width direction of the vehicle body and drip. Therefore, rainwater droplets will not drip onto the spark plug, and even if the vehicle is stopped for a long time in the rain, there is no risk of the engine misfiring due to leakage of spark plug current.
