Claims

[Scope of utility model registration request]

In a rubber crawler that is wrapped around the running part of a tracked vehicle such as a bulldozer, a pair of left and right protrusions to prevent wheels from coming off is provided in the center of the core inside the rubber crawler body, and one step lower on both sides of the protrusions. A rolling rail of a certain length is provided on the core metal, and the rolling rail is partially shifted in either the front or rear direction with respect to the center line in the front and back direction of the core metal to form a protrusion and a recessed part, A core metal for a rubber crawler, characterized in that a protruding portion and a recessed portion maintain an engaged state between adjacent rolling rails.
