Claims

[Claims for Utility Model Registration] A resin crawler IA is provided with core metals 7 at approximately constant intervals in its longitudinal direction, and rolling wheels 12a and 12b for guiding the ground-contacting side portion of the crawler 1A are arranged in parallel in the front-rear direction. In this crawler traveling device, the wheels 12a are adjacent to each other in the front and back at the front and rear portions of the crawler grounding side portion of the wheels 12a. 12a, 12b, and 12b are interlocked and connected so that they can move up and down backwards, and a pair of rolling wheels 1 on the front side can be moved up and down backwards.
2a, 12a, and the pair of wheels 12b on the rear side that can be raised and lowered against each other. The center distance Lb of each of the core bars 7 is set to be the same as or approximately the same as the sum of an integral multiple of the installation pitch P of the core metal 7 and 172 times the installation pitch P, and the front side is vertically movable. A virtual center point A of the pair of wheels 12a, 12a in the front-rear direction and a pair of wheels 12b, 12b on the rear side that can be raised and lowered in reverse.
A crawler traveling device characterized in that a distance H from a virtual center point B in the front-rear direction is the same as or approximately the same as a dimension that is an integral multiple of the core metal installation pitch P.
