<p>PURPOSE:To simplify structure by reducing the number of constitution elements of a chassis structure, securing the necessary rigidity by forming a chassis frame which supports two front wheels and two rear wheels to a lower part frame having a nearly rectangular shape and installing an upper part frame having a mountain shape on the side view. CONSTITUTION:A chassis frame which supports front two wheels 2 and rear two wheels 3 is formed as a lower part frame 4 having a nearly rectangular shape, and an upper part frame 6 having a mountain shape on the side view is installed on the lower part frame 4. Further, a box shaped cover body 5 which is opened downward is formed so that a driving device covering part which covers the driving device 30 such as an engine mounted at the rear part of the lower part frame 4 and fender parts 5b and 5c which cover the front and rear wheels are formed integrally, and the upper surface 5d is formed nearly flat, and the cover body 5 is applied over the upper part frame 4 and installed by screws, etc., and a handle shaft tilted rearward is supported on the upper part frame 6. The center at the rear part of the cover body 5 is recessed to the inside, and a step 7 for a driver A such as a caddy in standing state is formed.</p> |
