(Prior Art) In the past, iron caterpillars have been exclusively used as the undercarriages of civil engineering working machines, whereas rubber crawlers have been used in agricultural working machines. Fig. 1 and Fig. 2 A and B both show conventional examples. Fig. 1 shows an example of the suspension of an iron caterpillar, in which the center wheel of the roller wheel 2 runs over the shew link of the iron caterpillar 1. The structure is such that the parts move while being pressed into contact with each other. Figures 2A and 2B are examples of the undercarriage of a rubber crawler. As shown in each figure, the rubber crawler 1 has core metals 3 embedded at equal pitches.
1 is supposed to be used.

In this case, 2a and 2b are rollers used in the rubber crawler, the former being an intermediate roller type and the latter an outer roller type. Note that 4 is a steel cord.

(Problem that the invention aims to solve) By the way, rubber crawlers are increasingly being used in recent civil engineering working machines, but when using rubber crawlers in civil engineering working machines,
In the outer roller type shown in Figure 2B, since the rollers are in direct contact with the rubber crawler surface, a "gouging phenomenon (athlete's foot phenomenon)" occurs on the contact surface, making it durable for long-term use. It becomes something you can't get.

On the other hand, the intermediate roller type rubber crawler does not have this problem.Since the roller running surface is the square upper surface m of the core metal 3, the distance d from the steel cord 4 is
It is necessary to increase the distance between the corners and the distance between the corners, which causes problems such as increased vibration and the rolling wheels falling due to the phenomenon of center bending.
