Abstract:
To allow a differential mechanism to deeply get into a lubricant in low speed traveling and to allow the differential mechanism to shallowly get into the lubricant in high speed traveling though in a lubrication device of a simple structure, in a work vehicle including a mission case for housing the differential mechanism.SOLUTION: A first space portion A1 in which a differential mechanism 22 in a mission case is positioned and a second space portion A2 adjacent to the first space portion A1 are partitioned by a partition wall 75. An upper space 76 for allowing a lubricant scraped up from the first space portion A1 by rotation of a ring gear 22b to flow into the second space portion A2 is disposed at an upper side with respect to the partition wall 75. An outflow passage 86 for allowing the lubricant in the second space portion A1 to flow out to the first space portion A1 is disposed at a lower side with respect to the upper space 76.
