An operation lever of a work vehicle has the operation surface including: a connection portion; a front operation surface extending obliquely so that a height from a reference plane increases from the connection portion toward the forward side of the connection portion in a cross-sectional view including a front-rear directions and a front-side edge of the operation surface being defined as a front-side top portion; and a rear operation surface connected to the front operation surface, extending obliquely so that a height from the reference plane increases from the connection portion toward the backward side of the connection portion and a rear-side edge of the operation surface being defined as a rear-side top portion. A length in front-rear directions along the reference plane in the front operation surface is larger than a length in the front-rear directions along the reference plane in the rear operation surface.
