にしたものである。Here, in the case of this type of bearing, particularly in the case of a large size, it is quite difficult to integrally manufacture a cylindrical sliding element and fix it by shrinkage fitting, and a high load capacity is required. Due to the demand, so-called segment type bearings have been developed which divide the sliding element into a plurality of segments along the circumferential direction. In this segment type bearing, each segment obtained by dividing the stationary side sliding element along the circumferential direction is fixed to the inner peripheral surface of the bearing shell through a holding member such as a plurality of pieces extending in parallel to the axial direction. It is the one.
