In order to prevent vehicle body of a truck-loader type from causing undesirable vibrations and noises during its running, improvement is effected on its construction, so as to reduce and absorb vibrations and noises. For solving such problem, a truck-roller 1 to be pivotally supported on the truck frame b which is mounted on both left and right sides of the vehicle body a of the truck-loader type vehicle is shaped individually and separately in its inner wheel 1 a and outer wheel 1 b; then, these inner wheel 1 a and outer wheel 1 b are formed in a spacer D between an outer peripheral surface of the inner wheel 1 a and an inner peripheral surface of the outer wheel 1 b, to thereby be assembled into the truck-roller 1 . In this way, undesirable vibrations are absorbed by the elastic material 2 filled in the spacer D.
