To provide a traveling vehicle body capable of changing toe angles of left and right front wheels easily and even during traveling because there exists a traveling vehicle body which can execute appropriate work for the left and right front wheels by changing the left and right front wheels to toe-in or toe-out according to conditions of a field, however, conventionally this changes the left and right front wheels to replace with each other for change to toe-in or toe-out and the toe angle change is not easy and the toe angle change cannot be executed during traveling.SOLUTION: A traveling vehicle body having rear wheels as driving wheels and left and right front wheels 7, 7 steered by a steering operation device is provided with: a Pitman arm 27 steering the left and right front wheels 7, 7 in a longitudinal direction through tie rods 32L, 32R by steering operation of the steering operation device; and toe angle change mechanisms 29L, 29R operated by an actuator changing a toe angle of the left and right front wheels 7, 7 by changing a connection position of the tie rods 32L, 32R and the Pitman arm 27.SELECTED DRAWING: Figure 2

    【課題】左右前輪を圃場の条件に応じてトーインとトーアウトに変更して適切な作業が行えるようにした走行車体がある。然しながら、左右前輪を左右入れ替えてトーインとトーアウトに変更するものであり、そのトー角変更は容易ではなく、走行中にトー角の変更を行なうことができないものであった。そこで、容易に且つ走行中でも左右前輪のトー角の変更が行える走行車体を提供する。【解決手段】駆動輪である後輪と操向操作装置にて操向される左右前輪7,7を装備した走行車体において、操向操作装置の操向操作により左右前輪7,7をタイロッド32L,32Rを介して左右方向に操向回動させるピットマンアーム27を設け、タイロッド32L,32Rとピットマンアーム27の連結位置を変更させて左右前輪7,7のトー角を変更するアクチュエータにより作動するトー角変更機構29L,29Rを設ける。【選択図】図2
