To provide a wheel structure of an agricultural work machine which suppresses carrying-about of adhered mud by an outside wheel cap and an inside wheel cap and eliminates the fall of clods to a steering arm and so on when travelling in a muddy field, and can prevent trouble due to mud accumulation.SOLUTION: A wheel structure of an agricultural work machine comprises an outside wheel cap 21 which is detachably attached to a tire 20 of a spoke type wheel supported by a wheel support device 15 of a travel airframe 2 and covers an outer side face of a tire part 20a. In the wheel structure, an inside wheel cap 22, which covers a middle part side of a spoke 19 from an inner side face of the tire part 20a of the tire 20, is detachably attached, and the inside wheel cap 22 is configured in such a manner that a tire contact part 22c, which makes a circular arc on an outer peripheral side and is brought into contact with the tire part 20a, and an inclined plane part 27, which enters to a rim part 18a side from the tire contact part 22c and covers the spoke 19, are provided thereon.SELECTED DRAWING: Figure 2

    【課題】泥土質の圃場を走行するとき、外側ホイールキャップと内側ホイールキャップとによって付着泥土の持ち回りを抑制すると共に、操舵アーム等への土塊落下を無くし土溜まりによるトラブルを防ぐことができることができる農用作業機の車輪構造を提供する。【解決手段】走行機体2の車輪支持装置15に軸支されるスポーク型車輪のタイヤ20に、着脱自在に取付けられてタイヤ部20aの外方側面を覆う外側ホイールキャップ21を備える農用作業機の車輪構造であって、前記タイヤ20のタイヤ部20aの内方側面からスポーク19の中途部側を覆う内側ホイールキャップ22を着脱自在に取付けると共に、該内側ホイールキャップ22を、外周側に円弧状をなしてタイヤ部20aに接当させるタイヤ接当部22cと、該タイヤ接当部22cからリム部18a側に入り込ませてスポーク19を覆う傾斜面部27とを設けて構成する。【選択図】図2
