Abstract

PURPOSE: To enlarge a change angle of front wheels and to enable a small turn in turning in a small-sized traveling body arranged with an engine at the central part of a machine body. CONSTITUTION: A U-shaped rear frame 3 opening backward in a top view is connected to a front gear box 5 by a cylindrical middle frame 4 to constitute a machine body 7. Consequently, recessed parts A are formed at both sides of the middle frame 4, and an engine 17 and a pair of rear wheels 15 are respectively installed at the central part and the rear part of the rear frame 3. A pair of front wheels 11 to be rotated around a longitudinal shaft 10 and steered are laid at both sides of the gear box 5 so as to put the front wheels in the recessed parts A during the steering.

According to the above disclosed technology, the engine arranged in the center of the fuselage has a lower center of gravity that is sunk into the 8-shaped rod, but the left and right rods are Since it extends from both sides of the gear box to the rear, the rear end of the front wheel cannot be reached after the gear box when the steering wheel is steered greatly. Therefore, if this is used for a small traveling vehicle,
The front wheel housing that protrudes to the left and right from the gear box is shortened, and the cutting angle of the front wheel is reduced, making it impossible to make a small turn when turning.
