Description of the Related Art An elastic shoe for a crawler used for a construction vehicle is usually made of an iron footboard having a lug protruding from a tread side thereof in a direction perpendicular to a traveling direction of a crawler by a plurality of links. It is structured to be connected endlessly to each other via a bush and a pin. However, when traveling on a paved road surface, the road surface is significantly damaged.
A rubber shoe for protecting the road surface is integrated with the tread side of the vehicle. That is, there is known a structure in which a rubber shoe including a rubber pad and a support plate is integrated on the tread side of an iron shoe plate by using a foot plate mounting bolt of the iron shoe plate.

なる。BEST MODE FOR CARRYING OUT THE INVENTION An elastic shoe for a crawler according to the present invention.
As described above, both ends of the support plate forming the rubber shoe are specified with respect to the lug of the iron shoe plate, and further specify the relationship with the rubber pad, and together with the increase in the strength of the support plate, In addition, the strain generated in the rubber pad bonded to the tip of the support plate is reduced, and the occurrence of peeling of the two due to shearing force is reduced. By increasing the angle of inclination of both ends of the support plate with respect to the lug, the rubber pad completely covers the front end of the support plate and the amount of rubber at the front end is increased. This reduces the concentration of strain and reduces the occurrence of rubber pad cutting and adhesive peeling, thereby improving the durability of the elastic shoe for the crawler.
