PURPOSE:To remove mud clinging to the circumference of a tire and a lower surface of a door, etc., without fail as well as to make the whole car body washable clean to perfection, by installing plural shower nozzles whose injection water quantity per body unit area becomes larger in proportion as it goes down to the lower part of the car body. CONSTITUTION:In this car washing device, there are provided with plural shower nozzles 4A-4C as being set up in a feed water pipe 3 jetting washing water, inside a portal frame body. In this case, each of shower nozzles 4A-4C is set up so as to make an injection water quantity per body unit area larger in proportion as it goes down to the lower part A of a car body. For example, if an injection angle in each of these shower nozzles 4A-4C is set down to theta1-theta3 and the injection water quantity to Q1- Q3 respectively, it is set so as to become such relations of theta1<theta2<theta3 and Q1>Q2>Q3. Therefore, the injection water quantity per unit arear at the body lower part A grows larger than that at a body middle part B, and furthermore that at the body middle part B grows larger than that at a body upper part C. With this constitution, the injection water quantity is made as much as larger in proportion as going down to the body lower part where smudges are serious, thus the desired end comes to fruition. |
