PURPOSE: A roller couple of a stand for testing a roller is provided to efficiently support a vehicle by controlling clearance between rollers and to maintain a distance of the roller from a shaft by simplifying driving structure. CONSTITUTION: A roller couple of a stand for testing a roller comprises a frame(44) supporting an electric driving motor(46); a bearing block(50) having a driving pulley or a gear wheel(52) by being mounted on an output shaft(48) of the electric driving motor; main shaft arms(62,64) received by bearing contained in the frame; shafts(54,56) supporting the pulley or the gear wheel by being mounted on the roller; rotational shafts(66,68) unifying to the main shaft by being mounted on gears(74,76); a lever fixed on a shaft(90) of the frame by having arms(92a,92b). Thereby, the roller couple of the stand for testing the roller efficiently supports a vehicle by controlling clearance between rollers. Moreover, the roller couple of the stand for testing the roller maintains distance of the rollers from the shaft by simplifying driving structure.
