To provide a steering device for a work vehicle, which can eliminate a failure due to the entry of foreign objects into a transmission device as quickly as possible in a case where an automatic steering device is retrofitted to a work vehicle 1 and a drive unit of the automatic steering device is externally attached so that the high versatility of the steering device is attained.SOLUTION: A drive unit of an automatic steering device includes a transmission device configured to transfer power of an electric motor 41 to a steering shaft 42 and a trapping body 70 configured to prevent foreign objects from entering into the transmission device. Even when dusts are likely to fall on the transmission device due to a manual steering operation, the trapping body 70 traps the dusts and thereby prevents the dusts from entering into the transmission device.SELECTED DRAWING: Figure 6
【課題】作業車両1に自動操舵装置を後付けする場合に、その駆動部を外付けして汎用性の高いものに構成することを前提として、その際に生ずる伝動装置への異物の侵入に伴う障害を可及的に無くすことができる作業車両の操舵装置を提供する。【解決手段】自動操舵装置の駆動部は、電動モータ41の動力をステアリングシャフト42に伝達する伝動装置と、伝動装置への異物の侵入を阻止してこれを捕らえる捕捉体70を備え、手動のステアリング操作に伴ってごみが伝動装置上に落下しようとしても、捕捉体70がこれを捕らえて伝動装置への侵入を阻止するように構成する。【選択図】図6
