RIM ASSEMBLY AND TIRE TESTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a rim assembly in which even when an upper rim is pressed into a lower rim side, pressing force is suppressed from acting on a pin.SOLUTION: A rim assembly 10 includes: a through hole 23 extended so as to cross with a first reference surface S1 set on a first rim 20; a pin 27 erected on either one of the first reference surface S1 and a second reference surface S2 to be set on a second rim 40 and on which a groove part 29 is formed; a projection part 51 formed on the other of the first reference surface S1 and the second reference surface S2 and can be engaged with the groove part 29 of the pin 27 when the first rim 20 is rotated around an axial line C1 of the first rim relative to the second rim 40; a first support member 28 formed on the first reference surface S1; and a second support member 47 formed on the second reference surface S2, abuts on the first support member 28 when the first reference surface S1 and the second reference surface S2 approach each other and the projection part 51 is separated from both side faces of the groove part 29, and when the first reference surface S1 and the second reference surface S2 are separated from each other and the projection part 51 is engaged with the side face of the groove part 29, separates from the first support member 28.
