PURPOSE: To facilitate the adjustment to a running device by incorporating measuring rollers on which all wheels of an automobile are loaded, measuring all errors in a suspension of the running device while these rollers are rotated and constituting the device so as to eliminate errors. CONSTITUTION: Rollers 13 to 16 in pairs, each having a horizontal axis are provided to a frame 12 formed of a high strength beam, and accordingly, front and rear wheels of a vehicle such as a bus can be set on the rollers 13, 17. The pairs of the rollers 13, 14 and 15, 16 are journalled to rotatable bases 17, 18 and 22, 23, respectively. The basses 17, 18 and 22, 23 are carried on rails 20, 21 and 25, 26 which are formed in the frame 12. Further, measuring rollers 27, 28 are provided on the bases 22, 23, and forces exerted to the rollers 27, 28 can be measured by a measuring device 29 through the intermediary of a lever. Meanwhile, the bases 17, 18 are locked to the frame 12 through the intermediary of a dynamometer 30. |
