TECHNICAL FIELD The present invention relates to side brush tilting equipment of car wash system. More specifically, the present invention cleans (washes) the rear surface of a vehicle by sweeping the area where an unwashed band is generated in the middle due to interference between the circular brushes, while the brushes are tilted as if sweeping with a broom. This invention relates to a side brush tilting device for an automatic car wash machine, which is equipped with a reverse tilting means that can wash parts.

Generally, automatic car wash machines are classified into two types, gate type and tunnel type, depending on their functions.

In gate-type automatic car wash machines, the car to be washed is stopped at a designated position, and the car wash machine moves back and forth along the rails, spraying water and detergent onto the surface of the car to be washed, using brushes. This corresponds to a vehicle stop type car washing means that cleans the surface of the vehicle by washing the surface of the vehicle by washing the vehicle and spraying high-pressure air to dry the water on the surface of the vehicle.

Tunnel-type automatic car wash machines spray water and detergent onto the surface of the car being washed as it passes through the fixedly installed car wash body using a conveyor-like conveyor. This falls under the category of mobile car washing means, which uses water to clean the vehicle and sprays high-pressure air to dry the water on the surface of the vehicle.

In the tunnel-type automatic car wash machine described above, when cleaning the rear surface, an unwashed band was generated in the middle due to interference between the circular brushes. For this reason, conventionally, in order to clean the unwashed area, it has been necessary to additionally install a separate brush or to have a large space in which the brush can move back and forth.
