When the steering wheel is turned to the turning position, the suspension shaft 3a 'of the front wheel 3a becomes inclined line k.
Centered upward with respect to the horizontal direction L (direction of arrow b ')
It turns while drawing the trajectory of.

Therefore, when the front wheel 3a is steered to the left, the front wheel on the inner wheel side presses the floor in the steering direction. That is, in the case of a left turn, the inner wheel side front wheel 3a
Is rotated to draw a point trajectory of chain line a ₁ in Fig. 5, since the floor surface pressure, since the front wheels 3a rotate along a dashed line a _2, the body 1 is relatively one-dot chain line a ₃ And the vehicle body 1 is tilted by the angle θ. Therefore, the vehicle body 1
With this inclination, the inner wheel-side rear wheel 2a rises (ups) as indicated by a dashed line from the floor surface.

That is, when the front wheels are steered, the rear wheels on the inner wheel side in the steering direction float off the floor, and the vehicle body 1 runs with the driving force of the rear wheels on the outer wheel side. Therefore, when turning, FIG.
Of As, since the timing aligning the frame D based on the travel of the outer ring (black dots) are engraved, the pitch p ₁ of the turning range C is a domino chain as the pitch p ₂ of the straight running range S They are arranged at intervals that can be kept. Therefore, FIG.
Of As, the pitch p ₁ of the alignment of frame D in the turning region C is not occur phenomenon as becomes wider than the pitch p ₂ of the straight running range S.
