Claims

[Scope of utility model registration request]

A driver's seat 3 that can be switched forward and backward is provided with rollers 6 that allow it to be moved back and forth, and the above-described operation is carried out between a lower front position A for forward-facing work and an upper rear position B for backward-facing work. The movement of the seat 3 is guided by the rolling motion of the rollers 6.
In a work vehicle equipped with a guide 7 that guides along an inclined path F on the front side that is located upward toward the rear and a horizontal path R on the rear side that is connected to the slope path F on the front side, a pair of front and rear waist bending link mechanisms 8 and 9 are The front link 8A of the rear side hip-folding link mechanism 8 and the rear link 9B of the rear side hip-folding link mechanism 9 are pivotally supported on the vehicle body side, and
The rear link 8B of the front hip-folding link mechanism 8 and the front link 9A of the rear hip-folding link mechanism 9 are pivotally supported on the pivot portion of the roller 6 on the side of the driver's seat 3. and the vehicle body, and these pair of front and rear hip folding link mechanisms 8 and 9 are arranged so that when the driver's seat 3 is in the lower front position A, the rear hip folding link mechanism 9 is in an extended state. When the driver's seat 3 is in the rear upper position B, the front side hip-folding link mechanism 8 is folded in a posture substantially along the inclined path F. The waist-folding link mechanism 8 is arranged in an extended state and the rear waist-folding link mechanism 9 is arranged in a folded state in a posture substantially along the horizontal path R, and the driver's seat 3 is in a lower position A on the front side. At a certain time, when the front stopper 10A prevents rearward rotation of the front hip-folding link mechanism 8 in the hip-folding state, and when the driver's seat 3 is in the rear upper position B,
Rear stopper 10B that prevents downward rotation of the rear hip-folding link mechanism 9 in the hip-folding state.
A driver seat mounting structure for a work vehicle equipped with
