If it is located at another position B of the phase, for example, the placement angle of the traveling wheel 50 is 18 °, the placement angle of the auxiliary wheel 70 should be 11 °. That is, the steering angle of the auxiliary wheel 70, which is the outer wheel, should not be the same as the steering angle of the driving wheel 50, which is the inner wheel, and when the steering device 80 is installed as described above, the driving wheel 50 and the auxiliary wheel The steering angle difference of 70 is compensated for.
