PROBLEM TO BE SOLVED: To provide an air conditioning structure of a work vehicle capable of simplifying the structure.SOLUTION: An air conditioning structure of a work vehicle comprises an air guide path for guiding air to an air conditioner, and an inside/outside air switch mechanism 100 capable of closing either an outside air introduction port or an inside air introduction port. The inside/outside air switch mechanism 100 comprises: a rotatable rotary shaft 140 in which a left side notch 141 and a right side notch 142 are formed on the outer peripheral surface; a block member 160 which is fixed to the rotary shaft 140 and can be switched between a first state which blocks the inside air introduction port and a second state which blocks the outside air introduction port in accordance with the rotation angle of the rotary shaft 140; and a restriction member 130 for restricting the rotation of the rotary shaft 140 by being engaged with the left side notch 141 when the block member 160 is switched to the first state, and restricting the rotation of the rotary shaft 140 by being engaged with the right side notch 142 when the block member 160 is switched to the second state. |
