Claims

[Scope of utility model registration request]

In a traveling working vehicle, a hydraulic clutch 33 is disposed on a transmission shaft 32 in a transmission case 8 and is supplied with and discharged from hydraulic oil through an oil passage 44 bored in the transmission shaft 32. A cylindrical portion 45 that is integral with the mission case wall is formed on the inner surface of the transmission shaft 32 at an outer circumferential position of the transmission shaft 32 so as to protrude toward the hydraulic clutch 33, so that the oil passage 44 in the transmission shaft is positioned on the fixed position side. oil passage 51
The oil passage rotary joint portion 50 for communicating with the
An oil path forming device characterized in that an annular groove 49 formed on the outer peripheral surface of the transmission shaft 32 is sealed with an inner peripheral surface of the cylindrical portion 45.
