RIM ASSEMBLY AND TIRE TESTING MACHINE

摘要

This rim assembly is provided with: a first rim at which a first reference surface is formed; a second rim at which a second reference surface is formed; a through hole that extends in a manner so as to intersect the first reference surface at the first rim and through which a threading section is threaded; a pin that is provided upright at one of either the first reference surface or the second reference surface; a protrusion formed at the other of either the first reference surface or the second reference surface; a first support member provided to the first reference surface; and a second support member provided to the second reference surface. A groove that the protrusion engages is formed around the outer peripheral surface of the pin. The first support member and the second support member contact when the protrusion is separated from the groove, and the first support member and the second support member separate when the protrusion is engaged to the groove.
