  • Patent number: 11926363
    Abstract: A work vehicle according to the present invention includes left and right axle cases of a rigid axle type, and left and right suspension mechanisms movable in the up-down direction relative to body frames and separately supporting the left and right axle cases, respectively. The work vehicle also includes (i) a first projection projecting downward from the left or right one of the body frames, (ii) a second projection projecting upward from that position on either the left and right axle cases or a frame body integrated with the axle cases which is opposite to the first projection in the left-right direction, and (iii) a lateral rod having a first end connected with the first projection and a second end connected with the second projection.
