を特徴とする作業車両の操向操作装置。 In a steering operation device for a work vehicle, in which actuators 6 and 7 for operating left and right steering clutches and brakes are moved separately by a single operation lever 9,
The steering lever 9 is divided into a first member 9a that swings about a shaft-mounted portion 10 at the lower end as a fulcrum, and a second member 9b that is rotatably mounted 11 on the upper part of the first member 9a. and the second member 9b is connected to the first member 9a.
When the rotation is prevented by the latching mechanism 13, it rotates independently, and when it reaches the stroke end position of the independent rotation, the latching mechanism 13 is released and from then on it rotates together with the first member 9a. The inner 2 of the left and right operating cables is movably provided and connected to the arm parts 23, 23 extending left and right from the boss part 19 of the second member 9b.
4 and 24 are connected to the steering clutch/brake operating tools 6 and 7, respectively, and the inners 26 and 26 of another operation cable connected to both arms 25 and 25 at the lower end of the first member 9a are connected to the steering clutch and brake actuators 6 and 7, respectively. The steering clutch/brake actuators 6, 7 are connected to the steering clutch/brake operating parts 6, 7, and the steering clutch/brake actuators 6, 7 are moved to the steering clutch disconnection position by independent rotation of the second member 9b, and the steering clutch/brake actuators 6, 7 are connected to the steering clutch/brake operating parts 6, 7 together with the first member 9a. A steering operation device for a work vehicle, characterized in that the actuating tools 6, 7 are actuated to a braking position by rotational movement.
