Abstract: The present invention relates to a link seal for a track of a tracked vehicle, in which fine protrusions of an indefinite pattern are formed on the adhesive surface of the seating groove of the main body made of a high-strength resin and the adhesive surface of the seating part of the sub-body made of an urethane resin and then the adhesive surfaces of the seating groove and the seating part are treated roughly into surfaces of a fine concavo-convex shape to increase the adhesion between the main body and sub-body. The link seal includes: an annular main body including a seating groove, a circumferential flange portion, and an annular sleeve; an annular sub-body including a seating part; and an annular rubber ring made of a cushion material and having a through-hole 301 formed at the center thereof.
