摘要： An operation device (100) capable of switching operation of a transmission (7) of a work vehicle (1) includes an operation lever (130) that is rotatable in a first rotation direction about a first rotation shaft (144) and rotatable in a second rotation direction about a second rotation shaft (143) non-parallel to the first rotation shaft (144), an urging portion (136) that urges the operation lever (130) to move to a predetermined initial position, a first cam portion (170) that rotates following a rotation of the operation lever (130) in the first rotation direction, a second cam portion (150) that rotates following a rotation of the operation lever (130) in the second rotation direction, a first switch portion (190) that is pressed by the first cam portion (170) and detects the pressing in a state where the first cam portion (170) is rotated to a predetermined position, and a second switch portion (200) that is pressed by the second cam portion (150) and detects the pressing in a state where the second cam portion (150) is rotated to a predetermined position. The operation lever (130) is movable to a plurality of operation positions, the operation device (100) further includes a movement holding portion (133) (136) (181) that moves the operation lever (130) to the initial position when the operation lever (130) is positioned at a first operation position among the plurality of operation positions and holds the operation lever (130) in a state where the operation lever (130) is positioned at a second operation position when the operation lever (130) is positioned at the second operation position. The movement holding portion (133) (136) (181) includes an extendable portion (133) that is provided on the operation lever (130) and is expandable, and a recess (181) that receives a tip portion of the extendable portion (133) in an extension direction. The urging portion (136) urges the extendable portion (133) to extend such that the tip portion in the extension direction abuts on the recess (181). The recess (181) includes a first inclined portion (183a) that guides the extendable portion (133) such that the operation lever (130) positioned at the first operation position is moved to the initial position, and a second inclined portion (184a) that guides the extendable portion (133) such that the operation lever (130) positioned at the second operation position is held at the second operation position.

摘要： To provide a working vehicle configured to be operated with easy speed shifting even when an operation lever for speed shifting is difficult to operate due to the operator's posture or other factors.
The working vehicle (1) includes an operator seat, an armrest (15) arranged on a side of the operator seat (10). The armrest (15) includes an upper surface (16a) on which an operation tool arrangement portion (19) is arranged, the operation tool arrangement portion (19) arranging an operation tool; and a side surface (16d) having a concave portion (15a). The concave portion (15a) is located on an area overlapping, in a front-to-back direction, with another area including the operation tool arrangement portion (19).

摘要： To provide a working vehicle configured to be operated with easy speed shifting even when an operation lever for speed shifting is difficult to operate due to the operator's posture or other factors.
A working vehicle (1) includes an operator seat (10), an armrest (15) arranged on a side of the operator seat (10), and a speed shifter to change a traveling speed. The armrest (15) includes an operation lever (21) to be swung back and forth to cause the speed shifter to perform acceleration and deceleration, and an operation switch (30, 31, 32, 34, 35) to be pressed to cause the speed shifter to perform acceleration and deceleration.

摘要： It is possible to suitably operate switching of a transmission of a work vehicle. Provided is an operation device 100 which includes: an operation lever 130 that is rotatable in a vertical rotation direction about a vertical rotation shaft and is rotatable in a front-rear rotation direction about a front-rear rotation shaft non-parallel to the vertical rotation shaft; an urging portion 136 that urges the operation lever 130 to move to a predetermined initial position; a neutral cam portion 170 that rotates following a rotation of the operation lever 130 in the vertical rotation direction; a forward/backward cam portion 150 that rotates following a rotation of the operation lever 130 in the front-rear rotation direction; a neutral switch portion 190 that is pressed by the neutral cam portion 170 and detects the pressing in a state where the neutral cam portion 170 is rotated to a neutral pressing position; and a forward/backward switch portion 200 that is pressed by the forward/backward cam portion 150 and detects the pressing in a state where the forward/backward cam portion 150 is rotated to a forward pressing position or a backward pressing position.
