Abstract
Provided is a rubber wear resistance evaluation method including compressing and bonding a test sample of rubber with additional force to a circular circumferential surface of a rotation body rotated by a drive motor at a predetermined fixed position, holding the test sample in a state where movement of the test sample in a direction opposite to the addition force is always allowed, performing a wear test in which the test sample is worn, and using, at the time of evaluating wear resistance, an index based on at least one item out of two items including power required for driving and rotating the drive motor and a temperature of the test sample during the wear test, in addition to an amount of wear of the test sample.
