SOLUTION: Firstly, a tire is deflated and a wheel rim and a rod 25 are inserted into a hub 240 while a bead having a smaller diameter is upwardly directed. Next, a roller 19 is contacted with a bead of the tire utilizing a cylinder piston unit 23. At this time, a groove into which a usual lever is inserted is formed in order to draw one portion of the bead from the wheel rim by forcing an edge of the bead with the roller 19. Further, when a wheel is reversed, the roller 19 contacts with a side wall of the tire, an interlocking device 3 rotates and the bead is moved over a relief edge. At this time, the tire is left from the wheel.</p> |
