PURPOSE:To prevent a road face or a car body from being damaged by providing auxiliary wheels which rotate in contact with the road face when the car body is inclined. CONSTITUTION:When a car body is inclined, an auxiliary wheel 11 on the inclined side is rotated in contact with a road face, and the car continues running with a front wheel 2, a rear wheel 3, and the grounded auxiliary wheel 11, thus a stable run is assured without turning-over. Since shocks received from the road face through the auxiliary wheel 11 while running are absorbed by a buffer spring 12, it is unlikely that a fitting bolt 7 is broken under an abnormal load applied to the fitting bolt 7 of a counterweight 6 caused by the shocks or cracks are generated on the car body 8 or a frame, etc., even if the auxiliary wheel 11 is carelessly crashed into a sharp projection on the road face. |
