In a work vehicle as described above, a vertical plate member (an erect wall-like attaching plate 1) and a top plate member (a circumference covering body 2) projecting outwards in a direction perpendicular to the vertical plate member are provided, and the top plate member is disposed longitudinally along a front-rear direction. On the inner and outer sides of the top plate member, there are provided right and left attaching tongue portions 5, 6 having a same shape. One of these right and left attaching tongue portions 5, 6 is attached to the vertical plate member. With these, there are constituted right and left fenders 3, 4 which are configured to be right-left symmetric (see e.g. Patent Document 1).
As a tractor as an example of the work vehicle, there is known a tractor configured such that at right and left opposed areas in foot-rest regions formed by boarding steps, there are disposed operational pedals such as a brake pedal, a clutch pedal (a stopping pedal), etc. in distribution (see e.g. Patent Document 2).
