In an utility vehicle equipped with a cover displaceably attached to a chassis through a suspension mechanism, each suspension mechanism includes a shaft installed between the chassis and cover, a guide member having a plate member provided on lower half of the shaft and multiple plates (first plate and second plate) installed above and below the plate member to be contactable with the plate member and respectively formed at their centers with the through holes for passage of the shaft, a compression spring of roughly frustoconical shape for biasing the cover toward the chassis whose upper seating edge is attached to upper half of the shaft and lower seating edge is attached to periphery of the through hole of the cover, and an elastic member of roughly frustoconical shape formed at its center with a through hole to pass the shaft therethrough, wherein the cover is configured to be formed in roughly frustoconical shape similar to the elastic member.
