Abstract: An endless track link that is able to reduce stress concentrations and to improve efficiency of an assembling process of the endless track link is detailed. A stress reinforcing part is formed in the region in which stress concentrations are generated in a window area. The reinforcing part extends in a direction apart from a track shoe and includes an extended part of a through-hole into which a track shoe connecting bolt is inserted. A female thread for engaging with the track shoe connecting bolt is formed at the extended part of the through-hole.

Abstract: An object of the present invention is to provide an endless track link being able to reduce stress concentrations and to improve efficiency of an assembling process of the endless track link. The present invention is characterized in that: a reinforcing part (7) is formed in the region in which concentrates are generated in a window area (5); the reinforcing part (7) extends in a direction apart from a track shoe and includes an extended part of a through-hole (a plain through-hole 8 having a smooth inner surface) into which a track shoe connecting bolt is inserted; and a female thread (9) for engaging with the track shoe connecting bolt is formed at the extended part of the through-hole (8).
