A link seal for a caterpillar track is provided to reduce noise of a whole caterpillar and improve durability by preventing deformation of grease injected between a bushing and a pin. A link seal for a caterpillar track includes a first body(110), a second body(120), a third body(130), and a first supporting protrusion(140). The first body has a shape of a ring. The second body is arranged at an outer side of the first body to be separated by a predetermined distance from the first body. The third body connects the first body and a bottom of the second body, and has a first protrusion of which a center has a lower height than top surfaces of the first and second bodies. The first supporting protrusion is extended by a predetermined length to face each other from upper ends of the first body and the second body, and is formed along the upper ends of the first body and the second body so that end portions thereof are separated from each other. |
