Claims

[Scope of Claim for Utility Model Registration] (1) An end-shaped segment crawler track of a predetermined length is constructed by embedding a tension-retaining cord and a core bar in a crawler body formed of an elastic material, and In addition to connecting both core metals in a bendable manner,
An elastic crawler track characterized in that the endless elastic crawler track is constructed by sequentially connecting the connecting means. (2) At the connection part of each segment crawler track mentioned above,
The core metals at both ends of the segment crawler belt are connected by a hinge, and an elastic bushing and a shaft pin having a polygonal cross section that matches a polygonal cross-sectional hole formed in the axial center of the elastic bushing are inserted into the hinge part. The elastic track according to claim (1), characterized in that: (3) At the connection part of each segment crawler track mentioned above,
2. The elastic crawler according to claim 1, wherein core metals at both ends of the segment crawler are bendably connected by a metal plate.
