PROBLEM TO BE SOLVED: To provide a traveling body capable of carrying out the regulation of toe angles in the nearly same manner before and after the turning around when wheel-supporting arms for supporting wheels are attached to the traveling machine body by inverting the right and the left to change the treads.SOLUTION: The traveling body is constituted so that the toe angles may be regulated around a turning central axis (d) at the same angle (g) based on the line (f) in the front and rear direction at the same height position of the wheels 17 before and after the turning around when the attaching parts 22 of the wheel-supporting arms 19 are attached to the traveling machine body 13 by inverting the right and the left.COPYRIGHT: (C)2010,JPO&INPIT【課題】 トレッドを変更すべく、車輪を支持する車輪支持アームを左右反転させて走行機体に取り付けた場合に、反転前と反転後において、トー角の調整を同じように行うことができる走行体を提供する。【解決手段】 車輪支持アーム19の取付部22を左右反転させて走行機体13に取り付けたときに、反転前と反転後とにおいて、車輪17が同じ高さ位置で、前後方向の線fに対して同じ角度gの回動軸芯d回りにトー角の調整が可能となるように構成する。【選択図】図1
