Work vehicle includes an operation lever pivoting forward and backward stepwise through a plurality of operation positions; and a detent type retention mechanism holding the operation lever in each of the operation positions. The retention mechanism includes a coupling member coupled to the operation lever; and a retention member holding the operation lever via the coupling member. The operation lever and the retention mechanism are provided separately from each other, aligned in a direction intersecting with a pivot support shaft of the operation lever. The operation lever and the coupling member are reciprocally connected via a linking mechanism.

An input device includes an operating body that moves through an operation performed by an operator, a movable portion that slides in accordance with movement of the operating body, a lever including a first end portion that engages with the movable portion, a rotation center, a second end portion located on an opposite side of the rotation center from the first end portion, and a magnet provided on the second end portion, where the lever rotates in accordance with sliding of the movable portion, and a magnetic sensor disposed facing the magnet. A second length from the rotation center of the lever to the magnet is greater than a first length from the rotation center to the first end portion of the lever.
