<P>PROBLEM TO BE SOLVED: To provide a rubber crawler forming a lug part so as not to reduce driving force or braking force, in driving or braking of the rubber crawler. Ž<P>SOLUTION: This rubber crawler has a rubber crawler body part 11 formed in an endless shape and the lug part 10 projectingly formed from a flat part 28 of the rubber crawler body part 11, and is arranged in a traveling machine body, An undercut shape is formed on a front side wall 10b of the lug part 10. Thus, when the driving force or the braking force is impressed on the lug part 10, the lug part 10 is deformed by receiving a load, but since the deformed lug part 10 maintains a substantially vertical state to a surface of the crawler body part 11, grip force is excellently maintained to the ground surface, and reduction in the driving force or the braking force can be prevented.
