本発明は不整地走行用の自動三輪車、四輪車の車輪に装
着される超低圧タイヤの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in ultra-low pressure tires mounted on the wheels of tricycles and four-wheeled vehicles for traveling on rough terrain.

ていなかった。By the way, buggy-type automatic tricycles for traveling on rough terrain,
Four-wheeled vehicles are equipped with ultra-low pressure tires called balloon tires. That is, as shown in FIG. 1, an ultra-low pressure tire 120 is mounted on a wheel rim 111, and a tread portion 121 and a shoulder portion 1 of the ultra-low pressure tire 120 are mounted on a wheel rim 111.
22 is provided with a block 124 for ground resistance, but the sidewall portion 123 thereof was not provided with a block.

２からサイドウオール部１２３にかけて接地することと
なる。When a so-called saddle-riding type motor tricycle with one front wheel and two rear wheels equipped with such ultra-low pressure tires 120 or a saddle-riding type four-wheeled motor vehicle with two front and rear wheels is operated in a low to medium speed range. , the occupant puts his weight on the step on the opposite side to the turning direction, moves the center of gravity outward in the turning direction from the center of the vehicle body, and turns. This is especially true if there is no differential on the axle shaft. Therefore, in the case of a tricycle, the front wheel and the rear wheel on the outside of the turn, and in the case of a four-wheeled vehicle, the front and rear wheels on the outside of the turn contact the ground strongly, and the shoulder part 12 of the ultra-low pressure tire 120
2 and the sidewall portion 123 are grounded.

用が酷になり、超低圧タイヤ１２０の寿命に影響を及ぼ
すこととなる。However, in the past, since the sidewall portion 123 does not have a block, it is not always possible to obtain efficient grounding resistance, and the contacting of the sidewall portion 123 with the ground makes it difficult to use the tire, which shortens the life of the ultra-low pressure tire 120. This will have an impact.
尚最近では、前記バギータイプの鞍乗り型車両のエンジ

る。In order to achieve the above object, the present invention provides an ultra-low pressure tire to be mounted on the wheels of a tricycle or a four-wheeled vehicle for traveling on rough terrain, in which a block for ground resistance is provided from the tread portion, part of the shoulder, to the sidewall portion. The gist is what has been established.
以下に本発明の好適実施例を第２図以降の図面に基づい

す。As shown in the figure (an internal combustion engine 3 is mounted in a body frame 2 of a motorbike 1, a fuel tank 4 and a seat 5 are placed on the frame 2 in order from the front, and left and right steps 6 are placed on the bottom of the frame 2. A front wheel 9 is pivotally supported at the lower end of front forks 8, 8, which are supported at the front of the frame 2 to be operated integrally with a bar handle 7. In addition, an axle shaft of the two rear wheels 10.10 is pivotally supported at the rear end of a rear fork (not shown) which is pivotally supported at the rear of the frame 2, and a chain sprocket is connected between this axle shaft and the output shaft of the engine 2. A power transmission mechanism such as the following is installed, and therefore the two rear wheels 10 and 10 serve as driving wheels.

を行う。When the above-mentioned buggy-type saddle-riding tricycle 1 is operated on rough terrain such as sandy or muddy ground, when the vehicle is operated to turn at a low to medium speed range, unlike a motorcycle, when the vehicle is operated on the opposite side to the turning direction. In step 6, the occupant's weight is lifted, the center of gravity is moved from the center of the vehicle body to the outside in the turning direction, and the rear wheel 10 on the inside in the turning direction (arrow) is raised, and the front wheel 9 and the front wheel 9 are turned. Turning is performed with the outer rear wheel 10 strongly grounded.

する。As a result of the above turning operation, the ultra-low pressure tire 20 on the grounding side comes into strong contact with the road surface G from the shoulder part 22 on the outside of the turn to the sidewall part 23, as shown in FIG. Therefore, the shoulder portion 22 and the sidewall portion 23 on the inner side of the turn are crushed and bulge deformed 4-.
高速域では、重心を旋回方向内側に移動させる。At high speeds, the center of gravity is moved inward in the turning direction.
ただし、車体には遠心力が働くため、タイヤは同様に旋
回外側が強く接地する。However, since centrifugal force acts on the car body, the tires will similarly contact the ground strongly on the outside of the turn.

に行わしめることができる。Even if even the sidewall portion 23 comes into contact with the ground during travel, according to the ultra-low pressure tire 20 of the present invention, the sidewall portion 23 is provided with a large number of blocks 26 like other parts. Therefore, sufficient ground resistance can be obtained and the vehicle can turn smoothly without reducing traction.
尚この効果は砂地や泥地に限らず、摩擦係数・（μ）の
低い路面等においても、同様に発揮される。This effect is not limited to sandy or muddy ground, but is similarly exhibited on road surfaces with a low coefficient of friction (μ).

寿命化をも達成する・ことができる。As described above, since the blocks 26... are provided also in the sidewall portions 23, 23, the presence of the blocks 26 makes it difficult for the surface of the sidewall portions 23, 23 to be damaged even if the surface comes into contact with the ground. It is also possible to extend the life of the tire 20.
以上によりエンジン高出力化に伴う要求にも本発明の超
低圧タイヤ２０は充分に対拠することができる。As described above, the ultra-low pressure tire 20 of the present invention can fully meet the demands associated with higher engine output.
