<p>PURPOSE:To provide a motive power taking-out transmission structure having excellent operability and safety in a simple structure. CONSTITUTION:In a transmission structure for an agricultural work vehicle, a transmission system is constituted so that motive power from an engine can be supplied to a motive power taking-out shaft through a friction type hydraulic clutch 14 which is energized to the clutch releasing side and on which clutch throwing-in operation is carried out by supplying operating oil, and a gear shift type speed changing mechanism is provided on the downstream side of transmission of the hydraulic clutch 14. The transmission structure has a brake mechanism B constituted in such a way that when a hydraulic piston 28 in the hydraulic clutch 14 is returned/operated to a clutch releasing position, a braking operation part 39 interlocking with it is brought into pressure contact with a fixed side braking member 40 by clutch releasing energizing force, and braking is applied, and the fixed side braking member 40 is supported with a transmission case side fixing pin 41 so as to be capable of making relative rotation freely within a prescribed small range.</p> |
