Since the vibration is large, the amplitude is large and causes intense vibration. A crawler that takes this vibration countermeasure into consideration is a technology that uses a modified arrangement of the core metal and the grounding lug (Jikkoi 2-35032
There is a technique in which the shape of the core metal itself is modified (see Japanese Utility Model Application Publication No. 129683/1983, hereinafter referred to as conventional example 2).

There is a problem in that the difference in rigidity between the crawler and other parts becomes extreme, causing severe vibrations in a crawler having a so-called center wheel that rolls on the part having the engagement hole.

剛性差があり、振動が発生することがある。[0004] In the conventional example 2, the vertical width between the opposing corners for preventing wheel derailment inside the core bar is formed to be larger than the vertical width of the other wing parts, so that in the crawler having the above-mentioned center wheel, , vibration can be suppressed more than in conventional example 1. However, there are cases in which the core metals adjacent in the longitudinal direction of the band have only a substantially rubber portion, and in this case, there is still a difference in rigidity and vibrations may occur.

Another object of the present invention is to provide a crawler in which bending at the winding portion can be guaranteed.
