Abstract: Provided is a work vehicle in which a positioning antenna can be installed above a roof plate of a cab at an accurate position and in a proper attitude while preventing a positioning accuracy from being decreased by vibrations. The work vehicle includes a first mount member, a second mount member and a positioning antenna. The first mount member includes a left-side member fixed on the roof beam at the left side and a right-side member fixed on the roof beam at the right side. The second mount member is disposed above the roof plate across the left-side member and the right-side member. The positioning antenna is mounted on the second mount member.

Abstract: A center pillar (3) has a pipe structure having a hollow space (3a). In the center pillar (3), a lower end opening (3c) for connecting the hollow space (3a) to an outdoor space and an upper end opening (3b) for connecting the hollow space (3a) to an indoor space (10) are formed. The lower end opening (3c) and the upper end opening (3b) are arranged at a prescribed distance from each other in a longitudinal direction of the center pillar (3). Thus, a cab for work vehicle and a work vehicle capable of preventing dust, water, or the like from entering the cab and realizing an environment in the cab comfortable for an operator are obtained.
