Claims

[Claims for Utility Model Registration] 1. On the peripheral surface of one end of the power shift shaft on which the plurality of hydraulic clutches are mounted, a plurality of oil passages bored in the power shift shaft communicate with the plurality of hydraulic clutches. A plurality of annular grooves are formed, and the open ends of the plurality of annular grooves are sealed with a fixed seal body fitted onto one end of the power shift shaft, so that the plurality of hydraulic pressures are formed on one end of the power shift shaft. An oil passage forming device for a hydraulic clutch type transmission, which forms a plurality of oil distribution chambers for clutches, the fixed seal body being supported by a support that supports one end side of the power shift shaft via a bearing. An oil passage forming device characterized in that it is constituted by a wall and another seal mounted on the outer surface of the supporting wall. 2 Utility model registration The oil passage forming device according to claim 1, in which one oil distribution chamber of the plurality of oil distribution chambers is connected to the support wall body and another seal body. The oil path forming device is characterized by being arranged at the mating surface position.
