Abstract
A track shoe connecting linkhas shaft holesat both end portions. In the track shoe connecting link, a plurality of insertion holesare formed between the shaft holes, and window holesare formed so as to correspond to each insertion hole. A boltis inserted through each of the insertion holesand a nutis screwed onto a distal end of the boltin each of the window holes. Accordingly, the track shoe connecting linkis fixed to a track shoe. The area of the window holethat is adjacent to the second shaft holeis greater than the area of the window hole. Accordingly, the rigidity of the track shoe connecting linkbecomes smaller toward the second shaft hole
