The respective ring members 3, 4 are arranged in concentric circle shape, and the ones adjacent at the inner and outer peripheries are fitted to each other. The plurality of ring members comprise a main ring member 3 of plate shape and an auxiliary ring member 4 arranged at least at one of the inner and outer peripheries of the main ring member 3. The auxiliary ring member 4 has a cylindrical part 4a fitted to the main ring member 3, and a collar part 4b provided at the upper part of the cylindrical part 4a so that the upper face is flush with the main ring member 3.
