ABSTRACT:
Disclosed is an automotive rolling machine having a main frame section and a lengthy roller equipped to at least one side of the main frame section. The roller is tapered at the outer peripheries of its end portions, whereby, at the time of changing the advancing direction of the roller, the paved surface is not damaged by the outer peripheral angular portions of the roller. The main frame section has a frame at the front and rear end portions of which slider guides are laterally equipped in such a manner that sliders are slidably fitted into the slider guides. At the central portions of the sides of the frame, center pins are vertically supported. And to the underside of the center pins are fixed the central portions of lower frame members supporting the rollers as viewed in the longitudinal direction. The front and rear end portions of the lower frame members are connected to the sliders so that the lower frame members may be movable with respect to the sliders. Thus, the machine has high steerability. In addition, the frame of the main frame section is constructed in the form of a water tank, whereby the machine load is uniformly distributed to enhance the rolling effect.
