Claims

[Scope of utility model registration request]

(1) From the position provided at the front of the vehicle body, where the direction of the axle is orthogonal to the direction of vehicle travel, on one side there is at least the steering angle during normal driving, and on the other side at least the extension line of the axle is on the vehicle body. a driving wheel capable of steering the angle up to a position passing through a certain point arbitrarily selected above; a means for steering the driving wheel; a means for detecting that the axle of the driving wheel is oriented in the direction of the certain point; The drive means for the driving wheels are provided on both sides of the rear of the vehicle body, and are movable between a position perpendicular to the direction of movement of the vehicle and a position where the extension line of the axle passes through the above-mentioned fixed point. means for simultaneously displacing the rear wheel and the two trailing wheels respectively from one of the two positions to the other and vice versa;
and means for holding each wheel in its displaced position.

(2) The means for displacing each of the following wheels between the two positions is not interlocked at the steering angle for normal running of the driving wheels, and beyond that angle, the extension line of the axle remains at the above-mentioned constant position on the vehicle body. When the steering wheel is moved to a position passing through the point, the following wheel is moved in conjunction with the displacement of the steering shaft to a position where the extension line of the axle passes through the above fixed point on the vehicle body, and the driving wheel is moved so that the extension line of the axle is above the above point. The link mechanism is characterized by a link mechanism that displaces the following wheel to a position where its axle is perpendicular to the direction of travel of the vehicle when the steering angle is returned from a position passing through a certain point to a steering angle range for normal driving. A traveling vehicle according to claim 1 of the utility model registration claim.
