PURPOSE:To enhance the boarding and alighting ability of a vehicle body without deteriorating the stability and aerodynamic characteristic of the vehicle body, by elevatably assembling the rear section of a front body carrying front wheels to the front section of a rear body carrying rear wheels through the intermediary of a lift mechanism. CONSTITUTION:A body 1is divided into a front body 3 carrying front wheels 2 and a rear body 4 carrying rear wheels 4. Further, the rear section of the front body 3 is assembled to the front section of the rear body 5 through the intermediary of a lift mechanism 6. This lift mechanism 6 is composed of guide rails 7 arranged in the front section of the rear body 6 in the vertical direction, lift rollers 8 fixed to the lower rear section of the front body 3 and slidably engaged with the guide rails 7, a cylinder 8 having a cylinder tube 9a longitudinally rotatably attached to the lower section of the rear body 5 and an actuating rod 9b which is attached at its front end to the upper section of the front body 3, and a hydraulic motor 10 as a drive source of the cylinder 9. |
