作業車の変速操作装置。[Scope of Claim for Utility Model Registration] ■ A belt type continuously variable transmission 16 and a forward/reverse switching mechanism 17 are interposed in the traveling transmission system, of which the medal continuously variable transmission 16 is interposed.
Mechanism 2 for controlling the operation of the operating drive mechanism 26 in the increasing/decreasing direction.
7 is provided between the operating lever 29 that can be swung in a two-dimensional direction and the forward/reverse switching mechanism 17. A mechanism 30 is provided between the operating lever 29 and the control mechanism 27 to allow the operating lever 29 to be operated in opposite two-dimensional directions from the forward operating position and the reverse operating position. In conjunction,
In a speed change operation device for a work vehicle, which is provided with a mechanism 31 for operating the drive mechanism 26 from a speed change neutral state to an increasing speed side, the interlocking mechanism 31 includes the operation lever 29.
An arm 47 is connected to the control mechanism 27 and swings the same amount away from the operating shaft 46 of the control mechanism 27 in the opposite directions as the gear is shifted from the neutral position to the forward high speed side and the reverse high speed side. A speed change operating device for a work vehicle, characterized in that the arm 47 and the operating shaft 46 are pivotally connected. (2) The drive mechanism 26 and the control mechanism 27 move the drive mechanism 26 by an amount proportional to the amount of swing operation of the operation lever 29.
The speed change operation device for a work vehicle according to claim 0, which is linked via a mechanical feedback mechanism 32 that automatically switches the control mechanism 27 to an operation stop state when the control mechanism 27 is operated.
