A car washing machine is provided to reduce noise generated from a branch unit by arranging a first parallel pipe unit in parallel to a second parallel pipe unit. A car washing machine includes a branch pipe(51a), an inlet(57), first and second outlets(58,59), first and second duct hoses(61a,62a), and first and second parallel pipe units(64a,65a). The branch pipe branches air exhausted from a blower into a top nozzle and side nozzles. The inlet and the first and second outlets are formed at the branch unit. One end of the first duct hose is connected to the first inlet and the other end of the first duct hose is connected to the top nozzle. One end of the second duct hose is connected to the second outlet and the other end of the second duct hose is connected to the side nozzle. The first parallel pipe unit is installed in a connection part of the first duct hose and the first outlet. The second parallel pipe unit is installed in a connection part of the second duct hose and the second outlet. |
