<p>A wear test apparatus (1) comprises: an abrasive body (2) having an endless ring shape; a pair of abrasive body rollers (3) where the abrasive body (2) is wound, at least one half of the pair being capable of rotational driving; a test piece (20) formed of an elastic material; and a test piece holding medium (4) capable of moving the test piece (20) away from or toward a flat surface portion at an outer circumferential side of the abrasive body (2), the test piece (20) being pressed at the flat surface portion of the abrasive body (2) to measure an abrasion loss of the test piece (20). A reciprocating driving means (5) displaces the test piece (20) in parallel with the flat surface portion and toward a front side or a rear side in a driving direction of the flat surface portion which presses the test piece (20) of the abrasive body (2) wound around the abrasive body roller (3) which is rotationally driven.</p> |
