Accordingly, the vertical washing brush 20 is rotated by moving to the side of the vehicle by the operation of the left and right rotating frame 40. In the state where the vertical washing brush 20 is in close proximity to the vehicle, When the rotation is achieved, a load is generated in the vertical motor 21 due to the friction force, and the load of the vertical motor 21 is applied to the controller 70 as a constant signal through the load detection sensor 71.

Subsequently, the controller 70 outputs a signal for stopping the operation of the actuator 50 when the applied load detection value is high compared with a preset value, and as a result, the forward movement of the rod 52 results. Is stopped.

Therefore, the pair of vertical washing brush 20 is moved in one body and the body 10 while rotating in a state positioned at an appropriate interval on the side of the vehicle.

On the other hand, when the side width of the vehicle is not constant as shown in Figs. 6 to 7 and there is a bend, the vertical driving brush 20 when the main body 10 is moved along the rail 15 The load amount of the motor 21 is changed, and this load change value is applied to the controller 70 through the load detection sensor 71. Therefore, the controller 70 controls the operation of the actuator 50 in real time according to the load variation so that the vertical cleaning brush 20 can always maintain a proper distance with respect to the side of the vehicle.

In addition, through the adjustment of the spacing between the vertical washing brush 20 as described above, the car wash according to the present invention is able to perform a general car wash operation for vehicles of different widths, for example a large bus or a small bus or a van. .

The car wash constructed and operated as described above is able to adjust the gap between the vertical washing brushes installed to the left and right through the gap adjusting device, so that when the side of the vehicle is curved or the car washes having different vehicle widths can be universally washed. It can be effective.
