Claim:
An obstacle-removing device of a guided vehicle for removing obstacles on a guideway on which the vehicle is arranged to travel, said device comprising: at least one brush comprising a plurality of bundles of bristles having rigidity and arranged along a width direction of the vehicle; a brush holder holding the brush and attached to a vertically movable member; a vertical frame attached to a leading end in a traveling direction of the vehicle; a lifting/lowering mechanism attached to said vertical frame to lift and lower the brush holder by lifting and lowering the vertically movable member; a first pivoting point provided between the brush holder and the lifting/lowering mechanism for pivotally supporting a tip end of the brush holder via an intermediate connection member, such that the brush held by the brush holder is rotatable upwardly, the first pivoting point having said intermediate connection member laid in the width direction of the vehicle; and a first stopper face for restricting a rotation of the brush held by the brush holder toward the vehicle about the first pivoting point; wherein the brush holder is pivotally attached such that a contact point between the brush held by the brush holder and a running surface is positioned posterior to the intermediate connection member of the first pivoting point in the traveling direction of the vehicle so that the brush holder tilts forward when the brush held by the brush holder contacts the running surface to perform an obstacle-removing operation.
