The seal mechanism 130 comprises a fixed ring 131 fit to the protruding end 112a of the bush 112, and an annular elastic lip member 132 fixed to the fixed ring 131. The elastic member 132 has a lip that abuts on the internal face of the outer plate 121 so as to surround the protruding end 112a of the bush 112. COPYRIGHT: (C)2007,JPO&INPIT
