Japanese Patent JP2017203777

A

PROBLEM TO BE SOLVED: To suppress the useless ejection of a support liquid from a circular hole located at a place to which a tire is not grounded in a load support device.SOLUTION: A travelling test device 1 of a tire includes: a belt 5 horizontally wound around between two drums; and a load support device 6 for supporting a flat surface of the belt 5 from a lower face side. The load support device 6 is provided with liquid feeding means 7 for feeding a support liquid to the belt 5 and supporting the belt 5 from below. The liquid feeding means 7 includes a plurality of liquid feeding holes 10 capable of ejecting the support liquid to the belt 5 on the upper surface of the load support device 6. An ejection amount of the support liquid from each liquid feeding hole 10 is adjustable on the basis of a fluid pressure of the upper surface of the load support device 6. Flow amount adjusting means for adjusting a flow amount of the support liquid ejected from each liquid feeding hole is provided separately from the load support device. The plurality of liquid feeding holes provided in the load support device and the flow amount adjusting means for adjusting the flow amount of the support liquid ejected from the plurality of liquid feeding holes are connected by a plurality of conduit tubes.SELECTED DRAWING: Figure 2
