Abstract:
1. A sliding bearing formed into a half shape two of which are combined with each other to construct a cylindrical shape, with a plurality of groove portions formed on an inner peripheral surface along a circumferential direction thereof with a predetermined distance between the grooves and a predetermined depth dimension, wherein crownings for preventing interference with a shaft are each formed into an inclined shape toward an outer peripheral surface from an inner peripheral surface, at end parts in an axial direction, of the inner peripheral surface, and a depth dimension c of the groove portions and a depth dimension b of the crownings have the following relationships (A) to (C) in a mainly loaded part which is in a predetermined range, in the circumferential direction with a central crown portion of the sliding bearing interposed therein and which mainly receives load when a shaft rotates and a secondary loaded part which receives smaller load than the load received by the mainly loaded part: (A) 1≦b/c in the mainly loaded part≦200, (B) 0.1≦b/c in the secondary loaded part≦20, and (C) b/c in the secondary loaded part<b/c in the mainly loaded part; and wherein the value of b in the mainly loaded part is greater than the value of b in the secondary loaded part.
