To have a strength against an eccentric load, fixedly hold a shock absorbing member including a sliding piece against a bearing shell, not producing any co-rotating or dropping of their members even for a use of long period of time and further enable a predetermined bearing performance to be assured.

Inner diameter sides of both axial ends of a shock absorbing member 2 for use in supporting a plurality of sliding pieces 1 made of hard material such as ceramics divided into segments... at a bearing shell 3 are formed with annular tapered surfaces 2b having larger diameters as they approach axial outer sides, and a pair of annular pressor plates 7, 7 having an annular tapered receiving surface 7b extending along the annular tapered surface 2b are fixed to both axial ends of the bearing shell 3.
