To reduce the power consumption amount of a wheel testing device.SOLUTION: A wheel testing device is provided that comprises: a rail wheel support unit that rotatably supports a rail wheel; a wheel support unit that rotatably supports a test wheel by being contacted with the rail wheel; a first electric motor that causes the rail wheel and the test wheel to rotate; and a torque generation device that generates torque to be applied to the test wheel. The torque generation device includes a rotation frame that is driven to rotate by a rotation drive device, and a second electric motor that is attached to the rotation frame. At least one of the rail wheel and the test wheel is connected to the first electric motor via the torque generation device.SELECTED DRAWING: Figure 1 【課題】 車輪試験装置の電力消費量を低減する。【解決手段】 本発明の一実施形態によれば、軌条輪を回転可能に支持する軌条輪支持部と、試験輪を軌条輪に接触した状態で回転可能に支持する車輪支持部と、軌条輪及び試験輪を回転させる第１電動機と、試験輪に与えるトルクを発生するトルク発生装置と、を備え、トルク発生装置が、回転駆動装置によって回転駆動される回転フレームと、回転フレームに取り付けられた第２電動機と、を備え、軌条輪及び試験輪の少なくとも一方が、トルク発生装置を介して第１電動機に接続された、車輪試験装置が提供される。【選択図】図１
