<P>PROBLEM TO BE SOLVED: To provide an oblique-motion prevention mechanism for a car washing device that achieves the alignment of parallelism of a pair of right and left traveling wheels of a moving frame, moved along traveling rails installed above a vehicle to be cleaned, by a simpler configuration in a car washing device which has the moving frame and washes a vehicle by using injection nozzles installed in the moving frame. <P>SOLUTION: The oblique-motion prevention mechanism having a simple configuration is configured as follows. A first traveling wheel 3 is fixed to one end of a drive shaft 2, provided in a moving frame 10, with a key interposed in between. A second traveling wheel 4 is rotatably mounted to the other end of the drive shaft 2, with a slide bearing member 11 interposed in between. <P>COPYRIGHT: (C)2012,JPO&INPIT |
