Abstract
A seal for an endless track has a cross section having a centerline parallel to an axis of the seal and a configuration symmetric with respect to the centerline of the cross section. The seal can include an elastically deformably configured portion having a cross section like alphabetical letter X, and a protrusion extending from an intersection of legs of letter X in a bushing-side direction further than a plane connecting bushing-side end portions of the legs of letter X. The protrusion has an end surface where the protrusion contacts the bushing. The seal can further include an embedding portion embedded in a space between legs of letter X, on a bushing-side of the intersection of the legs of letter X.
