れている。2. Description of the Related Art A crawler shoe used for a construction vehicle usually has an iron footplate having a lug protruding in a direction perpendicular to a traveling direction of a crawler on a tread side of the crawler shoe. And endlessly connected to each other via a pin. However, when traveling on a pavement road surface, the road surface is significantly damaged. Recently, an elastic body for protecting the road surface has been integrated with the tread side of each shoe. That is, there is known a structure in which an elastic body such as a rubber pad is detachably integrated on the tread side of an iron shoe plate via a support plate, using a foot plate mounting bolt of the iron shoe plate in common.

ゴムにクラックが発生しにくい。The present invention has the above-mentioned structure,
It has the following features. (1) By lowering the height of both ends of the support plate from the height of both end lugs of the iron shoe plate, distortion generated in the rubber bonded to the front end of the support plate is reduced, and adhesion peeling due to shearing force is reduced. . (2) The lower end of the support plate is lower than the starting point of the curved portion at both ends of the lugs, and the upper end of the support plate is 1.5 m from the ends of both ends of the lugs.
It is more effective if the distance is not less than m. (3) Since the top surfaces of both ends of the lugs are covered with rubber pads, even when stepping on a stone or the like, the distortion and stress of the rubber at the tip of the support plate are relieved (because the rubber sandwiched between them is thick) Therefore, cracks are less likely to occur in the rubber.
