PROBLEM TO BE SOLVED: To enable a rapid temperature rise of a lubricating oil supplied to a sliding bearing 1 when an engine is warmed up.SOLUTION: A sliding bearing 1 is formed like a cylinder with a pair of upper and lower half bearings 2 put together. In both axial ends of the half bearing 2, an arcuate seal member 5 is provided over the entire region thereof in a circumferential direction. The seal member 5 is formed with a bimetallic material made of metal with a thermal expansion coefficient larger than that of the half bearing 2. At low-and-medium temperature during a warming-up operation of an engine, an edge part 5D of the seal member 5 is reduced in diameter so that opening parts 2E', 2E' of a crush relief part 2E are closed, thereby inhibiting a lubricating oil from flowing out of a sliding surface 2A. |
