を特徴とする作業車の走行変速装置。 A hydraulic clutch 4 is disposed on the transmission side of the gear transmission mechanism 9 that is manually operated, and this hydraulic clutch 4
The control valve mechanism V, which controls the supply and discharge of pressure oil to and from the hydraulic clutch 4, is composed of a manually operated gear shift member 27 and a fixed side member 28 that slidably supports the shift member 27, and is equipped with the hydraulic clutch 4. A hydraulic pump 23 is connected to the shaft end of the constantly rotating shaft 2, and this hydraulic pump 2
3 is connected to the oil passage 2 in the constantly rotating shaft 2.
2 to the hydraulic clutch 4, and
The control valve mechanism V is connected to the discharge port 24 through an oil passage 26 formed along the side wall of the mission case 1.
is configured to allow and block the flow of pressure oil from the oil passage 26 into the transmission case 1 as the speed change shift member 27 shifts, and the speed change shift member 27 is positioned at each speed change position. A travel transmission device for a work vehicle, characterized in that the control valve mechanism V is configured so that the hydraulic clutch 4 is in an engaged state at one time, and is in a disengaged state when the hydraulic clutch 4 is disengaged from each shift position. .
