PROBLEM TO BE SOLVED: To provide a work vehicle capable of improving durability of a fertilizer applicator.SOLUTION: A riding-type rice transplanter 1 includes a left fertilizer applicator group 100L, a right fertilizer applicator group 100R, and a feed driving force transmission mechanism 300 transmitting driving force for feeding fertilizers to the same. The feed driving force transmission mechanism has: a first fertilizing transmission rod 310 transmitting a driving force from an engine 20; a first relay member 320 relaying the driving force by the first fertilizing transmission rod to the right fertilizer applicator group 100R side; an intermediate transmission part 330; a second fertilizing transmission rod 340 transmitting the driving force by the intermediate transmission part to the right fertilizer applicator group 100R; a second relay member 350 which relays the driving force by the intermediate transmission part to the left fertilizer applicator group 100L side; and a third fertilizing transmission rod 360 transmitting the driving force by the second relay member to the left fertilizer applicator group 100L. The first relay member 320 is supported rotatably by a rotating bearing member 410 on the side connected to the first fertilizing transmission rod 310.SELECTED DRAWING: Figure 9【課題】施肥装置の耐久性を向上させることが出来る作業車両を提供すること。【解決手段】左側施肥装置群100Lと右側施肥装置群100Rとそれらに肥料を繰り出すための駆動力を伝動する繰出駆動力伝動機構300とを備えた乗用田植機1であって、繰出駆動力伝動機構は、エンシ゛ン20からの駆動力を伝動する第一施肥伝動ロット゛310と、第一施肥伝動ロット゛による駆動力を右側施肥装置群100R側に中継する第一中継部材320と、中間伝動部330と、中間伝動部による駆動力を右側施肥装置群100Rに伝動する第二施肥伝動ロット゛340と、中間伝動部による駆動力を左側施肥装置群100L側に中継する第二中継部材350と、第二中継部材による駆動力を左側施肥装置群100Lに伝動する第三施肥伝動ロット゛360とを有し、第一中継部材320は、第一施肥伝動ロット゛310と連結されている側において、転がり軸受部材410により回動可能に支持されている。【選択図】図9
