Abstract
A tired roller, which permits widening the field of view on both the left and right sides of an operator's section and is convenient for steering. In a tired roller with an operator's section arranged close to a right-hand side wall of a tired roller main body and with an ingress-egress step arranged on the tired roller main body , a space for the arrangement of the ingress-egress step is formed on the tired roller main body at a position between a left-hand side wall and the operator's section. In the arrangement space , the ingress-egress step which is provided with plural treads is arranged extending aslant from the operator's section toward a lower part of the left-hand side wall, so that an operator can look down at a road surface on the left side from the operator's section through a space above the treads . When the operator looks down at the road surface on the left side, conventional tired rollers allow him to see only a point Y significantly remote from the tired roller main body . This invention however makes it possible to see a point Z which is a point adjacent to the tired roller main body 11, whereby the field of view has been substantially enlarged on the left side.
