To provide a test device capable of performing tabletop tests of a tire under various road surface conditions by causing a carriage holding a test tire to travel along a road surface without moving the road surface during the test.SOLUTION: A tire test device according to an embodiment of the present invention includes: a road surface; one or more carriages on each of which a test tire is mounted and that rotatably holds the test tire and can travel along the road surface with the test tire in contact with the road surface; and guide mechanisms that guide movement of the carriage in the traveling direction. The guide mechanism is provided with: a rail extending in the traveling direction of the carriage; and a runner that is fixed to the carriage and capable of traveling on the rail. The runner includes: rollers that can roll on the rail and bearings that rotatably support the roller, and each bearing is a roll bearing provided with rolling elements that roll on circular raceway surfaces.SELECTED DRAWING: Figure 2

    【課題】試験中に路面を移動させずに、試験タイヤを保持したキャリッジを路面に沿って走行させることにより、タイヤの台上試験を様々な路面状態で行うことを可能とする。【解決手段】本発明の一実施形態に係るタイヤ試験装置は、路面と、試験タイヤが装着された試験タイヤを回転可能に保持し、試験タイヤを路面に接地させた状態で路面に沿って走行可能なキャリッジと、キャリッジの走行方向への移動を案内するガイド機構と、を備えている。ガイド機構は、キャリッジの走行方向に延びるレールと、キャリッジに固定され、レール上を走行可能なランナーと、を備えている。ランナーは、レール上を転動可能なローラーと、ローラーを回転可能に支持する軸受と、を備え、軸受は、円軌道上を転動する転動体を備えたころがり軸受である。【選択図】図2
