PROBLEM TO BE SOLVED: To provide a link for an endless track capable of releasing stress concentration, and improving workability in assembling. SOLUTION: A reinforcing part (7) is formed in an area where a stress is concentrated in a window hole (5), extends in the direction separating from a cover plate, and includes an extension part of a through-hole (natural through-hole having a smooth inner surface), in which a bolt for coupling the cover plate is inserted. A male screw (9) engaged with the bolt for coupling the cover plate is formed on the extension part of the through-hole (8). COPYRIGHT: (C)2008,JPO&INPIT
