To provide a tire testing machine, by which a pitch between an upper rim and a lower rim can be changed according to a tire width while reducing the number of seal members being disposed so as to further prevent air leakage during testing than the prior art.SOLUTION: A lower spindle 21 includes a lower retaining flange 210A for retaining a lower rim 61, and a lock piece 250. An upper spindle 22 includes an upper retaining flange 221 for retaining an upper rim 62, and an upper spindle engagement part 224. An insertion amount into an inner space S of an insertion part 222 is adjusted, a plurality of lock engagement parts 250A of the lock piece 250 is engaged with a plurality of insertion engagement parts 224A of the upper spindle engagement part 224, by which a pitch between the lower rim 61 and the upper rim 62 is adjusted according to a width of a tire T.SELECTED DRAWING: Figure 11 【課題】従来よりも試験中のエア漏れを防止するために配置されるシール部材の数を減らしつつタイヤの幅に応じて上リムと下リムとの間隔を変更することが可能なタイヤ試験機を提供する。【解決手段】下スピンドル２１は下リム６１を保持する下保持フランジ２１０Ａと、ロックピース２５０とを有する。上スピンドル２２は、上リム６２を保持する上保持フランジ２２１と上スピンドル係合部２２４とを有する。挿入部２２２の内部空間Ｓへの挿入量が調整され、ロックピース２５０の複数のロック係合部２５０Ａと、上スピンドル係合部２２４の複数の挿入係合部２２４Ａとが係合することで、タイヤＴの幅に応じて下リム６１と上リム６２との間隔が調整される。【選択図】図１１
