To provide a traveling body that is able to easily position a traveling unit and an axle when the traveling body is extended in width, a traveling body for a construction machine that is able to easily fix the traveling unit and the axle, and a construction machine that is able to easily extend the traveling body in width.SOLUTION: An embodiment of the present invention is a traveling body for a construction machine including a pair of left and right traveling units and an axle supporting the pair of left and right traveling units such that a width therebetween can be extended/shortened. In the traveling body, the traveling units respectively have frames in which the axle is inserted and mounted. The axle has: an axle body that obtains a shortened width of the pair of traveling units by inserting and mounting both ends of the axle into the respective frames; and extension portions provided so as to be extendable from both the ends of the axle body and that obtain an extended width of the pair of traveling units by their being inserted and mounted in the frames. This traveling body includes cylinder units respectively disposed between the frames and the extension portions in order to fix the axle and the traveling units.SELECTED DRAWING: Figure 3
【課題】本発明は、走行体を拡幅した際に、走行部とアクスルとを容易に位置決めすることができる走行体、及び走行部とアクスルとを容易に固定することができる建設機械の走行体と、走行体を容易に拡幅することができる建設機械とを提供することを課題とする。【解決手段】本発明の一態様は、左右一対の走行部と、この左右一対の走行部の幅を拡縮可能に支持するアクスルとを備える建設機械の走行体であって、上記走行部が、上記アクスルが挿入着されるフレームを有し、上記アクスルが、両端部が上記フレームに挿入着されることで上記一対の走行部の縮幅状態を得るアクスル本体と、このアクスル本体の両端部から延出可能に設けられると共に上記フレームに挿入着されることで上記一対の走行部の拡幅状態を得る延長部とを有し、上記拡幅状態で、上記アクスルと上記走行部とを固定するために、上記フレームと上記延長部との間に配されるシリンダユニットを備える。【選択図】図3
