A rice husker includes a pair of husking rolls. One of the pair of husking rolls is attached to a main shaft and the other of the pair of husking rolls is attached to an auxiliary shaft movable to be close to and away from the main shaft. The rice husker includes abnormality determination means. The abnormality determination means determines that the husking rolls fail to work normally when vibrations having a preset intensity larger than the preset intensity are successively detected by a vibration sensor until a certain time elapses. The certain time is from the start of a husking action to disappearance of distortion on a surface of the husking roll. The vibration sensor is provided on at least either of bearing units of the main shaft and the auxiliary shaft. The vibration sensor detects vibrations occurring due to the husking action by the pair of husking rolls.
