Claims

[Scope of utility model registration request]

A top brush is rotatably provided at one end of an arm supported in a swingable manner, and a lifting cylinder connected to the arm to swing the arm is provided, and pressure is communicated with one working chamber of the lifting cylinder. A liquid tank is provided which has a chamber and a release chamber that communicates with the other working chamber, and the release chamber of this liquid tank is opened to the atmosphere, and a compressed air supply pipe is connected to the pressure chamber, and the compressed air supply pipe is connected to the pressure chamber. Starting from the upper side of the supply pipe, a switching valve that switches between supply and discharge, a shutoff valve, and a rising air intake pipe with a check valve that allows inflow only to the compressed air supply pipe side are installed, and the vehicle height is increased. 1. A top brush position control device for a car wash machine, comprising a control section that operates the switching valve and the cutoff valve based on a signal.
