１項に記載の作業車のミツシヨン構造。[Scope of Claim for Utility Model Registration] 1. A front wheel transmission 6, a hydrostatic continuously variable transmission 7, and a gear transmission are arranged in order from the front in a transmission case 5 disposed at the rear of the fuselage, and an engine 3
The power from the hydrostatic continuously variable transmission 7 is transmitted to the rear wheels 2 via the hydrostatic continuously variable transmission 7 and the gear transmission, and the power branched from the gear transmission is transmitted from the gear transmission through the hydrostatic continuously variable transmission 7. The transmission is transmitted to the front wheel transmission 6 via the transmission shaft 14, and the front wheel transmission 6
In addition, a partition wall 21 is provided to surround the transmission shaft 14 portion of the hydrostatic continuously variable transmission 7 to prevent lubrication within the case of the front wheel transmission 6 and the transmission case 5. A transmission structure for a work vehicle configured to allow oil to flow through a gap formed between the partition wall 21 and the transmission shaft 14. 2 The partition wall 21 is a hydrostatic continuously variable transmission 7
A transmission structure for a work vehicle according to claim 1, which is constructed of a pipe member concentrically inserted into a transmission shaft 14 portion within the transmission shaft 14.
