PROBLEM TO BE SOLVED: To provide a gauge wheel device configured to allow only an anti-soiling body to be easily replaced.SOLUTION: A gauge wheel device 23 is used for a farm working machine 1. The gauge wheel device 23 includes a rotating body 51 which rotates around a horizontal rotational center axis X along the horizontal direction. On the outer periphery of the rotating body 51, an anti-soiling body 55 as a cylindrical body, which is hardly soiled, is detachably provided. The rotating body 51 has a supporting part 66 for partially supporting an inner peripheral surface of the anti-soiling body 55. The size of the supporting part 66 of the rotating body 51 in a direction along the rotational center axis X is smaller than the size of the anti-soiling body 55 in the direction along the rotational center axis X.COPYRIGHT: (C)2014,JPO&INPIT【課題】土付着防止体のみを容易に交換できるゲージ輪装置を提供する。【解決手段】ゲージ輪装置23は、農作業機1に用いるものである。ゲージ輪装置23は、左右方向に沿った水平な回転中心軸線Xを中心として回転する回転体51を備える。回転体51の外周部には、土が付着しにくい円筒状の筒状体である土付着防止体55を脱着可能に設ける。回転体51は、土付着防止体55の内周面を部分的に支持する支持部66を有する。回転体51の支持部66の回転中心軸線Xに沿った方向の寸法が、土付着防止体55の回転中心軸線Xに沿った方向の寸法よりも小さい。【選択図】図1
