A crawler track where damage on drive lugs is reduced. Grooves (26) in the circumferential direction of the crawler track (10) are arranged at the roots of the drive lugs (24). By this, tensile strain or compressive strain occurring in the roots of the drive lugs (24) when the crawler track (10) is wrapped over a wheel (14) etc. can be relaxed. Also, when the crawler track (10) meanders, a lateral load causes lateral pressure from the wheel (14) to a drive lug (24), producing tensile strain in the root of the drive lug (24). However, such tensile strain can be relaxed because the wheel (14) does not come into contact with the drive lugs (24)in the meandering movement.
