<P>PROBLEM TO BE SOLVED: To provide a rubber crawler including a drive engagement part having excellent durability. <P>SOLUTION: This rubber crawler 1 includes: lugs 2 formed on an outer peripheral surface; and the drive engagement part formed on an inner peripheral surface in order to transmit driving force. The rubber crawler is transmitted with the driving force by engaging a sprocket 100 with the drive engagement part. The drive engagement part includes: hard engagement members 5 buried at a constant pitch in the peripheral direction of the rubber crawler 1; and recessed parts 3 arranged in each portion between the engagement members 5 and receiving the tooth parts of the sprocket. With the rubber crawler, since the tooth parts of the sprocket are engaged with the recessed parts arranged in each portion between the hard engagement members, damage or the like to the drive engagement part is suppressed in comparison with the existing case that the tooth parts are made to abut on drive projection parts projecting on the inner peripheral surface. It is also possible to reduce contact pressure in such a manner that the shape of each of the recessed parts is appropriately changed and an engagement area with respect to the tooth part is enlarged. <P>COPYRIGHT: (C)2013,JPO&INPIT |
