TRANSMISSION STRUCTURE OF WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To further surely avoid seizure of a bearing in a transmission case. SOLUTION: A wide gear 80 integrally rotating with a first transmission shaft 16 is equipped on one end side of the first transmission shaft 16. A transmission gear 82 integrally rotating with a second transmission shaft 62 is arranged on one end side of the second transmission shaft 62 juxtaposed in parallel to the first transmission shaft 16 so as to always mesh with the wide gear 80. A large diameter gear 84 integrally rotating with the second transmission shaft 62 is arranged on the other end side of the second transmission shaft 62. A transmission gear 85 integrally rotating with a third transmission shaft 63 is equipped on the third transmission shaft 63 juxtaposed in parallel to the first transmission shaft 16. A first shift gear 33 integrally rotating with the third transmission shaft 63 is arranged on one end side of the third transmission shaft 63 so as to be relatively slidable in a meshing position and an unmeshed position to the wide gear 80. A second shift gear 36 integrally rotating with the third transmission shaft 63 is arranged on the other end side of the third transmission shaft 63 so as to be relatively slidable in a meshing position and an unmeshed position to the large diameter gear 84.
