Work vehicle

A work vehicle comprising:

• a brake pedal;
• a notch structure attached to the brake pedal and including a notch;
• a stay including a through-hole;
• a grip assembly inserted into the through-hole;
• and
• a brake lever including a claw at one end;
• wherein
• the grip assembly includes:
• a rod with a circular cross-section and a linear shape;
• a grip at a first end of the rod;
• a collar at or adjacent to the first end of the rod so as to cover an outer periphery of the rod;
• a plain washer at a second end of the rod;
• a pin that covers an outer periphery of the rod, is slidable with respect to the rod, and is fastened at or adjacent to the second end of the brake pedal;
• and
• a compression spring that interconnects the plain washer and the pin and that covers the outer periphery of the rod;
• the through-hole includes a first region in which the collar is slidable, and a second region with a length in a width direction that is shorter than an outer diameter of the collar and longer than an outer diameter of the rod;
• when the grip is pulled in an unlocked state in which the collar is located inside the first region and the grip assembly is not locked inside the through-hole, a state is transitioned into a locked state in which the compression spring is compressed by the pin and the plain washer, the brake lever rotates, the claw moves toward the notch, and the rod is located inside the second region and the grip assembly is locked inside the through-hole;
• and
• when the brake pedal is stepped on in the locked state, the claw and the notch engage with each other, and the brake pedal is locked.
