PURPOSE:To provide a surface preparation device unit which is mounted on a vehicle and can easily carry out surface preparation work even on a vertical wall face and a ceiling face. CONSTITUTION:A surface preparation device unit on a vehicle has a surface preparation device unit 4 which scrapes a vertical wall face 3a managed as a scraped face 3 and is loaded on a vehicle, and scrapes the vertical wall face 3a by the surface device unit 4 as the vehicle is run, and a supporting device 2 to movably support the surface preparation device unit 4 at a fixed position is provided on the vehicle. A base plate 15 which can move in parallel in a direction where it approaches to and separates from the scraped face 3 and energized toward the scraped face 3 is provided in the supporting device 2, and the base plate 15 and the surface preparation device unit 4 are mutually connected through an adjustable joint 7, and moreover, a coil spring 8 to energize the surface preparation device unit 4 into a posture to bring it into contact with the scraped face 3 is arranged between the supporting device 2 and the surface preparation device unit 4. |
