PROBLEM TO BE SOLVED: To provide a vehicle disinfection device capable of properly disinfecting a vehicle.SOLUTION: A vehicle disinfection device 1 includes vertical piping 3 arranged on the lateral side of a vehicle movement area 2. First lateral nozzles 11 are installed on the vertical piping 3 so that their injection port 11a opens toward a first direction orthogonal to a traveling direction in a plan view. Second lateral nozzles 12 are installed on the vertical piping 3 so that their injection port 12a opens toward a second direction inclined to the front side of the traveling direction with respect to the first direction in a plan view. Third lateral nozzles 13 are installed on the vertical piping 3 so that their injection port 13a opens toward a third direction inclined to the rear side of the traveling direction with respect to the first direction in a plan view.SELECTED DRAWING: Figure 1
