してある事を特徴とする。 In summary, the present invention provides the above-mentioned crawler traveling device in which the connecting member 4 is constituted by a bent sheet metal whose opposing portions 4a, 4a are located in the left-right direction and has an upward opening, and the upper edge of the opposing portion of the connecting member 4 The horizontal frame 3 is connected to both the opposing portions 4a, 4a, and 3a, respectively, with
4a, and the portions of the opposing portions 4a, 4a that protrude above the upper surface of the horizontal frame 3 are connected to the crawler core protrusions 12a, 1.
It is characterized in that it is positioned in contact with the side edge of the crawler 2a and is configured to also serve as a sliding guide member for the upper rotating portion of the crawler 12.
