The invention relates to a working vehicle which can improve a workability of a maintenance, inspection and the like with respect to a portion around an engine, and can tilt up a rear hood together with a tilt-up floor. An upper side of an engine (not shown) can be covered in a rear end portion side of a floor (35). A hinge mechanism (38) is arranged between a front end portion of the floor (35) and a rev-frame (25), and the floor (35) can be tilted up via the hinge mechanism (38). A rear hood (32) is coupled by hinge to a first support column (15) of a mounting bracket (4) supporting the floor (35), and is structured so as to be freely opened and closed. It is possible to tilt up the floor (35) in a state of attaching the rear hood (32), by canceling a fixed state of the mounting bracket (4) to a supporting and fixing member such as a counter weight (2) or the like.
