PROBLEM TO BE SOLVED: To provide a device for sterilization of a vehicle, capable of preventing waste of an antiseptic solution.SOLUTION: The device 1 for sterilization of the vehicle includes: an antiseptic solution spray means 41 which sprays the antiseptic solution toward a vehicle S; and a control means 42 which controls the antiseptic solution spray means 41. The antiseptic solution spray means 41 has an upper first nozzle group and an upper second nozzle group. The control means 42 has a discrimination unit which discriminates whether the vehicle S is large or small. When the vehicle is large, the antiseptic solution is sprayed from the first nozzle group and the second nozzle group, and when the vehicle is small, the antiseptic solution is sprayed from only the first nozzle group.【課題】消毒液の無駄を防止できる車両消毒装置を提供する。【解決手段】車両消毒装置1は、車両Sに向けて消毒液を噴射する消毒液噴射手段41と、この消毒液噴射手段41を制御する制御手段42とを備える。消毒液噴射手段41は、下側の第1ノズル群および上側の第2ノズル群を有する。制御手段42は、車両Sが大型か小型かを判別する判別部を有する。大型車両なら第1ノズル群および第2ノズル群が消毒液を噴射し、小型車両なら第1ノズル群のみが消毒液を噴射する。【選択図】図1
