To provide a construction machine capable of easily and reliably regulating rotation of a tip part of an axle and capable of preventing losing of a fixing member for regulating the rotation of the tip part even with a crawler frame removed.SOLUTION: A construction machine of the present invention is a construction machine having a lower travel body, and the lower travel body includes a track frame having a plurality of axels extending in a lateral direction relative to a traveling direction of the lower travel body, and at least a pair of left and right crawler frames connected to the plurality of axels. A tip part of the axle is configured to be rotatable in the horizontal direction relative to a body part of the axle, and has a fixing member installed between the tip part and the body part and regulating rotation of the tip part. A position at which rotation of the tip part is regulated includes a straight position where the tip part extends straight from the body part and a bending position where the tip part vertically bends from the body part.SELECTED DRAWING: Figure 4

    【課題】本発明は、クローラフレームを取り外した状態であっても、容易かつ確実にアクスルの先端部の回転を規制でき、かつ上記先端部の回転を規制する固定部材を紛失することを防止できる建設機械を提供することを課題とする。【解決手段】本発明に係る建設機械は、下部走行体を備える建設機械であって、上記下部走行体が、走行する向きに対して左右の方向に延びる複数のアクスルを有するトラックフレームと、上記トラックフレームの上記複数のアクスルに連結される少なくとも左右一対のクローラフレームとを備え、上記アクスルの先端部が上記アクスルの本体部に対して水平方向に回転可能に構成され、上記先端部と上記本体部との間に装着されて上記先端部の回転を規制する固定部材を有し、上記先端部の回転を規制する位置が、上記本体部から上記先端部が真直に延びる真直位置と、上記本体部から上記先端部が垂直に屈曲する屈曲位置とを含む。【選択図】図4
