A utility vehicle equipped with driving wheels attached to a chassis to run about a working area and a cover suspension connecting the chassis and a cover attached to the chassis. The cover suspension is provided with a shaft disposed to extend in gravity axis direction between the chassis and the cover with an upper portion attached to the cover and a lower portion attached to the chassis, and a converting member fastened to the shaft to convert force acting on the shaft to movement in a horizontal direction orthogonal to the gravity axis direction. In the vehicle, the shaft is made of resin, and a reinforcing member is inserted in an axial core of the shaft extending downward in the gravity axis direction in the shaft beyond a position where the converting member is fastened to.
