PURPOSE:To fix a floating wheel in a simple and assured way for a fixing device provided to each floating wheel, by setting a T-shape arm movably in both direction of the floating wheel and the lateral side of the arm. CONSTITUTION:For the fixing devices 40 and 50, the T-shape arms 43 and 53 are shifted toward the outside, and a car is moved onto a stage. Then the driving wheels 1 and 2 plus the floating wheels 3 and 4 are positioned respectively. For the device 50, the fixing bars 52' and 52'' of an arm fixing member 52 and the arm 53 are moved along a rail component 51. Then the arm 53 is shifted toward the wheel 4 after setting a rod-shape part at the center of the wheel 4. The fixing bars 54' and 54'' hold the wheel 4 between to position the wheel 4 at an opposite position. Then the arm 53 is fixed on the member 51 by means of the member 52, and the bars 54' and 54'' are shifted. A wedge-shape part is pressed to the circumference surface opposite to the wheel 4. In the same way, the wheel 3 is fixed by means of the device 40. |
