Summary: | Provided is a tire testing machine capable of measuring a force generated in a tire with high precision. The tire testing machine includes a spindle shaft (20) for holding a tire (T), a housing (22) for rotatably supporting the spindle shaft (20) through a rolling bearing (25), a running device (10) having a surface rotated by rotational driving and imparting a rotational force to a tire contacting the surface, and a measurement device (4) which is provided in the housing (22) and measures a force and moment generated in the spindle shaft (20) when the tire (T) is running. Furthermore, the tire testing machine includes a torque canceller (5) for preventing the spindle shaft (20) from such an impact that rotational, friction torque (My1) generated by rotational friction, which is received by the spindle shaft (20) in the housing when the spindle shaft (20) rotates, is imparted onto the shaft (20). The torque canceller (5) is equipped with a motor (30) for the spindle shaft, which imparts a torque for cancelling the impact of the rotational friction torque (My1) to the spindle shaft (20). |
