Abstract

There is disclosed a work vehicle having an openable/closable hood for covering an engine and a radiator mounted on a vehicle body frame, an air cleaner having an intake pipe and an elastic body for closing a gap present around the intake pipe. The elastic body includes a radiator side first elastic portion, a hood side second elastic portion and an engaging portion for engaging and retaining the second elastic portion to the first elastic portion. Under a closed state of the hood, the engaging portion maintains the second elastic portion under the engaged state, and the elastic body maintains the intake pipe at a predetermined position and closes the gap.
