PURPOSE:To make it easy to move wheels upwardly and downwardly during movement of a vehicular body and maintain the wheels at a lower position with respect to the vehicular body, by mounting to a lever frame an operating pedal which may be moved downwardly by depression and maintain the wheels at the lower position with respect to the vehicular body. CONSTITUTION:Lateral shafts 2 and 3 are arranged in parallel to each other at the lower position of a vehicular body 1. The lateral shaft 2 is provided with a lever frame 4, and the lateral shaft 3 is provided with a lever frame 5. The lever frame 4 is provided with wheels 7 at the front end thereof, and the lever frame 5 is provided with wheels 8 at the rear end thereof, both the lever frames 4 and 5 being connected by a pin 6. A connecting plate 13 is connected at the rear end of the lever frame 5, and a support pipe 14 is fixed to one side of the connecting plate 13. An arm 15 is loosely engaged with the support pipe 14 at one end thereof, while an operating pedal 11 is attached to the other end of the arm 15. When the pedal 11 is lowered, the wheels 8 are lowered, and in cooperation therewith, the wheels 7 are also lowered. Both the wheels 7 and 8 may be maintained at their lower positions, and when the pedal 11 is depressed and released, the vehicular body 1 comes into contact with the ground. |
