SOLUTION: Peripheral wall member locking pawls 24, 25 are arranged on a crown member 20 having a nut locked pawl to be locked to the lower end face of the fixing nut 4. A circular collar portion 32 having a cut-out portion 33 is formed at the upper part of a peripheral wall member 30. A ring 34 is arranged inside the peripheral wall member 30 in a loosely fitted condition. On a demounting tool 70, a push-down leg portion 72 is arranged which can be inserted into the cut-out portion 33 for pushing down the ring 34. The push-down leg portion 72 has a cut-in portion 72a whose lower end abuts on the lower edge of the circular collar portion 32. COPYRIGHT: (C)2006,JPO&NCIPI
