摘要： A working vehicle, wherein a steering wheel for steerably operating a running part is installed on an operation part through a steering wheel pivot shaft, a steering link mechanism incorporated in a link box is interlockingly connected to the steering wheel pivot shaft, and the trunnion arm of a continuously driving transmission for swing increasing and decreasing the rotating speed of a swing power transmission system is interlockingly connected to the steering link mechanism so as to interlock the counterclockwise and clockwise rotating operations of the steering wheel with the forward and reverse rotating operations of the continuously variable transmission for swing, whereby the operating performance can be assured satisfactorily.

摘要： One operating lever is provided for moving a traveling vehicle with a working machine back and forth and the working machine vertically and operating a sub-transmission, and a sub-transmission switch (37) is provided in a recessed portion (30b) formed in a grip (30a) of a back-and-forth operating lever (30) so that a quick operation can be effected by a single hand without any mistake. In addition, the working machine vertically moving lever (32) is constructed so as to interlock with a spool of a vertical motion control valve via a motor so that the speed of the motor is gradually reduced when the working machine vertically moving lever (32) is in a lowering operation, whereby a drastic lowering is prevented.

摘要： A pump operating unit (40) is provided in an operating section for controlling the steering and speed change of travelling sections (1L, 1R) connected interlockingly to a pair of variable flow rate control pumps (PL, PR) via link mechanisms (NL, NR) for a spool, and operated by a steering mechanism (33) and a speed changing mechanism (37). Accordingly, the natural vibration occurring in the variable flow rate control pumps (PL, PR) is absorbed by the link mechanisms (NL, NR), and hence the vibration transmitted to the pump operating unit (40) is attenuated. The propagation of the vibration to the steering mechanism (33) and speed changing mechanism (37), which are interlockingly connected to the pump operating unit (40), is prevented.
