摘要： PROBLEM TO BE SOLVED: To provide a rubber crawler having a rolling wheel passing surface where a core is buried through which a rolling wheel passes while coming into contact therewith, the inner peripheral surface of which is high, and in which the problem of pitting is not caused in the rolling wheel passing surface in the upper area of the portion where the core is buried even if the rubber crawler gets in sand, gravel, or mud.
SOLUTION: A groove 26 is formed at the rolling wheel passing surface 16 in the upper area of the portion of the rubber crawler 10 in which the core 12 is buried. The groove 26 is recessed from the rolling wheel passing surface 16 by an amount at which a rolling wheel 24 is not brought into contact with the bottom 26a of the groove 26 when a frame load is applied thereto. The circumferential width W1 of the groove 26 is smaller than the width of the core 12. When the groove 26 is projected on the core 12, the groove 26 is accommodated in the core 12. The bottom 26a of the groove 26 is generally the same as the surface of the inner peripheral section 18 of the rubber crawler 10 other than the rolling wheel passing surface 16. The bottom 26a of the groove 26 is tilted to the outer peripheral side laterally outward.
