PROBLEM TO BE SOLVED: To provide a structure for a rubber crawler using a specific material and further exhibiting the effect of the maximum limit. SOLUTION: A high hard rubber layer 10 (in this example, the rubber having hardness of 90°JIS-A is used) is arranged on a traveling surface on which a rolling wheel 20 is rolled, is uniformly vulcanized/adhered with a rubber material forming a base body of the rubber crawler, and is projected to a slightly inner peripheral side than an inner peripheral surface of the rubber crawler. Thereby, generation of athlete's foot phenomenon on the traveling surface of the rolling wheel is suppressed. COPYRIGHT: (C)2010,JPO&INPIT
