Abstract
Official abstract text for this publication.
A crawler track shoe core metal is plate shaped and is clamped and fixed by a fixing member to a moving link provided at a travelling body. The crawler track shoe core metal includes a cutout portion, a through-hole, and a raised portion. The cutout portion is formed indented in a face at the moving link side. The through-hole pierces through inside the cutout portion in a plate thickness direction and is inserted with the fixing member. The raised portion projects out from a through-hole peripheral edge of the cutout portion toward the moving link side, and has a projecting end with a height that does not reach the face at the moving link side.
First claim
Opening claim text (preview).
What is claimed is: 1. A crawler track shoe core metal that is formed in a plate shape, and that is clamped and fixed by a fixing member to a moving link provided at a travelling body, the crawler track shoe core metal comprising: a cutout portion that is formed indented in a face on a moving link side; a through-hole that pierces through inside the cutout portion in a plate thickness direction for receiving the fixing member; and a raised portion that projects out from a through-hole peripheral edge of the cutout portion toward the moving link side, the raised portion having a projecting end with a height that does not reach the face on the moving link side. 2. The crawler track shoe core metal of claim 1 , wherein a surface roughness of a face on a fixing member side is lower than a surface roughness of the face on the moving link side. 3. A resilient crawler track shoe comprising the crawler track shoe core metal of claim 1 having a face on a fixing member side covered by a resilient body.
