It descends by its own weight while balancing weight with 10W and 11W.

  As shown in FIG. 1, the upper surface brush rotation is performed in a state where the gate-type car wash machine body 1 is located at the start position (standby position) in front of the vehicle to be cleaned V, which is stopped between the traveling rails 5 and 5. When the motor 17 is driven to rotate the upper surface brush 16 in the direction of arrow a, and the driving motor 6 is driven to move the portal car wash machine body 1 in the direction of arrow b in FIG. 1, the outer periphery of the rotating upper surface brush 16 is rotated. When the surface comes into contact with the upper surface of the vehicle body, the swing arm 10 is swung around the support shafts 9 and 9 to brush and clean the upper surface of the vehicle body. As the portal-type car wash machine body 1 continues to travel, the upper surface brush 16 swings around the support shafts 9 and 9 so as to follow and contact the upper surface of the vehicle body with an appropriate contact surface pressure, thereby brushing and cleaning those vehicle body surfaces. To do.

  After completion of the cleaning process, the upper surface brush device TB is held in the upper storage position indicated by the solid line in FIG.

  By the way, as shown in FIG. 4, when the vehicle upper surface of the vehicle V to be cleaned having the projection E such as an emblem attached to the upper surface of the vehicle body is cleaned, the upper surface brush 16 is raised to avoid the projection E. The upper surface brush 16 bounces when the upper surface brush 16 is lowered and brought into contact with the upper surface of the vehicle body after the upper surface brush 16 passes through the protrusion E and is brought into contact with the upper surface of the vehicle body. 16 may occur, and if the strength of the support shafts 9 and 9 is small, the torsion acting on the support shafts 9 and 9 is increased to cause a swing angle shift in the left and right swing arms 10 and 10.

  In such a case, the swing arm balance weights 10W and 10W of the balance weight device BW reduce the twist generated between the swing arms 10 and 10 and the weight arms 11 and 11 of the support shafts 9 and 9. As compared with the conventional one in which the swing arm balance weights 10W and 10W are not provided, the swing angle deviation of the left and right swing arms 10 and 10 is generated even if the strength of the support shafts 9 and 9 is reduced. Can be prevented.

  Further, by reducing the strength of the support shafts 9 and 9, the peripheral members such as the bearings B1 and B2 that support the support shafts 9 and 9 can be reduced, thereby reducing the size of the gate-type car wash machine itself. The weight can be reduced, and the cost can be greatly reduced.

  As mentioned above, although the Example of this invention was described, this invention is not limited to the Example, A various Example is possible within the scope of the present invention.

  For example, “cleaning” in the above-described embodiment includes “cleaning process” using a detergent and other processes such as “rinsing process” and “polish process” by rotating the brush.
