1. A work vehicle comprising:
a ROPS (Rollover Protection Structure) that comprises a first pipe, a second pipe, and a connection mechanism connecting ends of the first pipe and the second pipe in a longitudinal direction,
wherein the connection mechanism comprises:
a plate-shaped first joint member provided at the end of the first pipe in such a manner as to protrude from the end of the first pipe toward the second pipe;
a plate-shaped second joint member provided at the end of the second pipe in such a manner as to protrude from the end of the second pipe toward the first pipe; and
a coupling bolt coupling the first joint member and the second joint member to each other,
wherein the first joint member has, at a position exposed from the first pipe, a coupling hole into which the coupling bolt is insertable, and the second joint member has, at a position exposed from the second pipe, a coupling hole into which the coupling bolt is insertable, and
wherein the first joint member and the second joint member are coupled to each other by the coupling bolt passed through the coupling holes while plate surfaces of the first joint member and the second joint member overlap each other,
wherein the ROPS further comprises at least one cross frame connected to the first pipe and the second pipe in a direction in which the at least one cross frame intersects the first pipe and the second pipe,
wherein the at least one cross frame comprises a horizontal bridge frame connected to the first pipe and the second pipe in such a manner as to intersect the first pipe and the second pipe along a horizontal direction, and
wherein the horizontal bridge frame is channel-shaped with an opening facing downward, the horizontal bridge frame having an upward facing surface extending in the horizontal direction, and downward extending side surfaces bent downward from two sides of the upward facing surface.
