However, railcar brakes have a larger mass and a larger torque than car brakes, so that bending and vibration are generated on the rotating shaft and the swing shaft, and accurate torque-related information is required. Data could not be obtained. Further, since large-sized devices are provided on both sides of the brake under test 10 in the axial direction, the state of the brake under test 10 during the brake test could not be sufficiently observed. Furthermore, when mounting and removing the brake 10 to be tested, it is necessary to move the movable base 11 to move the torque meter portion by 1 m or more, which takes time for the operation and increases the size of the test room due to the moving space.
