When the cylinder 19 becomes inactive and the swing shaft 6 rotates clockwise from the position 60 to the position 68 and descends, the upper brush 7, which was rotating at the upper limit position (A), is moved downward (A). ), the gate-shaped traveling frame 1 starts moving forward (step S1), reaches the position (c) where the upper brush 7 contacts the front of the vehicle V, and the swing arm 5 moves to the lower limit position (c). When the swing angle detection device detects that one swing angle (an angle of about 10° from the vertical line passing through the swing axis 6) has been exceeded (step S2), the forward movement of the gate-shaped traveling frame 1 is stopped. The swing shaft 6 is rotated counterclockwise (step S3), the swing shaft 6 is raised to the upper limit position 6c, and the upper brush 7 is moved to (d).

The upper brush 7, which was rotating at the upper limit position of When the swing angle detection device detects that the swing arm 5 has reached the abutting position (wa) and has exceeded the third swing angle (approximately 30 degrees from the vertical line passing through the swing axis 6). (Step 515), the swing shaft 6 is rotated counterclockwise (Step 316), and when the swing shaft 6 rises to the intermediate position 6b and the upper brush 7 reaches the (force) position (step 517
), if the third deflection angle has not yet been exceeded (step 51B), the swing shaft 6 is stopped at that position (step 519). On the other hand, if the swing angle exceeds the third deflection angle in step 51B, the swing shaft 6 rotates further and step 520
), when the swing shaft 6 reaches the upper limit position 6c (step 52
1), its upward movement is stopped (step 522), and in this way the upper brush 7 cleans the bonnet surface of the vehicle (2). Then, when the upper brush 7 reaches the position where it contacts the windshield (event) and exceeds the second deflection angle (step 523), the second deflection angle is reached as in the case of washing the wagon type vehicle (3) described above. The same operations as Step 37 to Step Sll in Figure 6 are performed (Step 324 to Step 32B), whereby the upper brush 7 moves from the (Y) position to the (I) position to clean the windshield surface. , furthermore, after reaching the ceiling surface at the position (S), it moves along the routes (T), (N), and (S) while following the ceiling surface.

At the same time, the side brushes 40, 40 are rotated in the opposite direction to move the front side brushes 40, 40 outwardly while cleaning the front of the vehicle, and at the same time, the lower side brushes 3,53 are also moved outwardly. side brush 4
0.40 and the lower side brushes 53 and 53 reach the outer bank, the gate-shaped traveling frame 1 is returned to the starting position, and after the upper surface brush 7 is lowered, the portal-shaped traveling frame 1 is made to go back again. As shown in FIG. 17, in the process of re-traversing the gate-shaped traveling frame 1, the top brush 7 is moved to the Steps 334 to S45 in the figure
The upper surface of the vehicle body is washed while performing the following operations (step 55).
