<p>Motors are disposed inward in radial directions of rollers 109, 109 on which wheels T, T of a vehicle V are placed, thereby enabling torsion rigidity of a rotation system to be increased owing to a box-shaped high rigidity structure constructed of a torque meter 108 and a rotary proximal portion 106 and a rotational balance to be improved by concentrating heavy loads in a way that saves a space. Further, since a vehicle load can be applied from outward in the radial direction to conical bearings 104, 105 that bear the rollers 109, flexural moment does not act unlike a case of supporting a rotary shaft as by a conventional technology, and a long life-span of the conical bearing can be ensured. Moreover, the motor is provided inwardly of the rollers 109, and hence a distance between the rollers 109, 109 can be arbitrarily set. Accordingly, the chassis dynamometers 100, 100 can be installed in adjustment to positions of the individual wheels T, T of the vehicle V, whereby a width of the roller 109 can be reduced, an inertial mass can be restrained small, and consequently a test for a low µ path can be reenacted on a bench while saving the space.</p> |
