いる。The frame 2 includes a pair of main frames 61 r 62 which are bent into a substantially rectangular shape, and a plurality of spacer frames 7.
Both ends of the main frames 61 and 62 are connected to a spacer frame 71 that supports the front wheels 3. A U-shaped wheel support frame 8 is attached to both ends of this spacer frame 71, and the front wheel 3 is supported on this wheel support frame 8 so as to be steerable.

ートである。Further, a spacer frame 73 on the soil side of the front end of the main frame 61, 62 is provided with a steering head 14 that supports the steering shaft 13, and a steering head 14 is provided in the center of the spacer frame 71. A bearing portion 15 is provided to support the lower end portion of. A bar handle 16 is attached to the upper end of the steering shaft 13, and an arm 17 is attached to the lower end. A link mechanism 18 for steering the front wheels 3 is supported on this arm 17 . Reference numeral 19 denotes a seat disposed above the front cover and rear cover (not shown).
次に、上記不整地走行用三輪車の動作を説明する。Next, the operation of the tricycle for traveling on rough terrain will be explained.

ム１７の回動に伴なって、リンク機構１８を作動する。The driver rides the vehicle while straddling the seat 19 and gripping the bar handle 16. To make a left turn, right turn, turn, etc., the bar handle 16 is rotated in the desired direction of travel, like a normal two-wheeled vehicle. Depending on the stiffness, the steering shaft 13 rotates by a predetermined angle, and as the arm 17 rotates, the link mechanism 18 is operated.
これによって、前車輪３は必要な角度だけ転舵され、車

車輪３に追従して方向が変えらｈるので、容易に進路変
更を行なうことができる。As a result, the front wheels 3 are steered by the necessary angle, and the traveling direction of the vehicle body is changed. At this time, the rear wheels 4 follow the front wheels 3 and change direction, so the course can be easily changed.
なお、上記実施例では、後車輪４にのみリヤサスペンシ
ョン１１を配設した三輪車について説明したが、第３図

例では、後車輪４を駆動輪とし、前車輪３を操舵輪とし
たが、前車輪３を駆動輪としても良い。In this case, the wheel support frame 8 is not directly connected to the spacer frame 71, but includes support arms 221, 222 whose one ends are supported via pole joins 21 at the lower part of the spacer frame 71 and the main frames 61+62, and the main frames 61+62. 61 + 62 is supported by a front suspension member with one end supported above. Further, in the embodiment, the rear wheels 4 are used as driving wheels and the front wheels 3 are used as steered wheels, but the front wheels 3 may be used as driving wheels.
以上、述べたように、本発明の不整地走行用三輪車によ
れば、前車輪を２輪、かつ、後車輪を１輪にしたので、
従来の三輪車または四輪車に比べてコーナリング性能の
向上を図ることができる。As described above, according to the tricycle for traveling on rough terrain of the present invention, since there are two front wheels and one rear wheel,
Cornering performance can be improved compared to conventional three-wheeled vehicles or four-wheeled vehicles.
