Claims

[Scope of utility model registration request]

The back and forth swing of the operation lever 14B is controlled by the first
A first interlocking state in which the operating lever 14B is interlocked with the valve _V3 , and the left and right swinging is linked with the second valve _V4 for the working device, and the back and forth swinging of the operating lever 14B is linked with the second valve _V4 , and , the left-right swing is the first
In order to switch to the second linked state in which the valve _V3 is linked, the first joint part 23A and the first rod 22A are connected, and the third joint part 23
C and the second rod 22B to form the first interlocking state, and the second joint portion 23B
and the first rod 22A, and the fourth
The first rod 22A is selectively fitted to the first and second joint parts 23A and 23B so that the joint part 23D and the second rod 22B are connected to form the second interlocking state. The valve operating structure for a work vehicle is provided with a valve operating structure for a working vehicle, in which the second rod 22B is attached so as to be selectively fitable and connectable to the third and fourth joint portions 23C and 23D, At least one of the first and second joint parts 23A, 23B and the first rod 22A is provided with a magnetic part 32 that attracts the other, and the third and fourth joint parts 23C, 23D and the second rod 23B are provided with a magnetic part 32 that attracts the other. A valve operation structure for a working vehicle, in which at least one of the magnetic parts 32 is provided with a magnetic part 32 that attracts the other.
