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

    【課題】荷重支持装置において、タイヤが接地していない場所にある円形孔から支持液が無駄に噴出することを抑制する。【解決手段】本発明のタイヤの走行試験装置1は、2ドラム間に水平に架け渡されたベルト5と、ベルト5の平坦面を下面側から支持する荷重支持装置6と、を有し、荷重支持装置6には、ベルト5との間に支持液を供給してベルト5を下方から支持する給液手段7が設けられ、給液手段7は、ベルト5との間に支持液を吐出可能な給液孔10を荷重支持装置6の上面に複数備えており、荷重支持装置6の上面の流体圧力に基づいて、各給液孔10からの支持液の吐出量が調整可能とされていて、各給液孔から吐出される支持液の流量を調整する流量調整手段が、荷重支持装置とは別に設けられ、荷重支持装置に設けられる複数の給液孔と、複数の給液孔から吐出される支持液の流量を調整する流量調整手段と、が複数の導水管で繋がっている。【選択図】図2
