<P>PROBLEM TO BE SOLVED: To achieve a structure which improves stability of a connection state between a thrust roller bearing 2b and a radial roller bearing 1b, while reducing the number of components and improving assembly workability. <P>SOLUTION: The axial one end of the inner peripheral surface of an outer ring 26a constituting the radial roller bearing 1b is provided with an engaging part 29 radially protruding from the inner peripheral surface. At least a circumferential part in the tip of a cylindrical part 31 provided at the radial inner end of a thrust retainer 16b constituting the thrust roller bearing 2b is provided with an elastic deformation part 32 radially elastically deformed only when the engaging part 29 passes through from the axial one side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
