In a work vehicle, a through-hole in a stay includes first and second regions. When a grip is pulled in an unlocked state in which a collar is located inside the first region and a grip assembly is not locked inside the through-hole, a state is transitioned into a locked state in which a compression spring is compressed by a pin and a plain washer, a brake lever rotates, a claw moves toward a notch, and a rod is located inside the second region and the grip assembly is locked inside the through-hole. When a brake pedal is stepped on in this locked state, the claw and the notch engage with each other, and the brake pedal is locked.

A brake lever support structure includes: a brake lever movable between a working position at which a parking brake of an off-road vehicle works and a cancel position at which the parking brake is cancelled; and an interior panel defining an inner surface of a cabin of the off-road vehicle. The brake lever extends from inside of the cabin to outside of the cabin through the interior panel. The interior panel includes a stopper that contacts the brake lever at the cancel position to restrict movement of the brake lever.
