Patent ID: 8651742

Claim:
A sliding bearing formed cylindrically by abutting joining surfaces of a pair of half bearings to each other and pivotally supporting a rotary shaft rotatably by a sliding surface inner peripheral surface of both half bearings, wherein in an inner peripheral surface adjacent to an inner peripheral edge of each of the joining surfaces of the half bearings, a crush relief comprising a notch part is formed and a dust pocket is formed in each of the inner peripheral edges and comprises a pair of rectangular grooves which are formed in each of the inner peripheral edges of the joining surfaces and communicate with each other, and circumferentially extends from the inner peripheral edges of the joining surfaces and comprises a recess part and a foreign-substance discharge groove inclined in the axial direction relative to the axial direction of the half bearings and comprising a first linear groove extending from the dust pocket and opening in an end face in an axial direction in at least one of the half bearings and a second linear groove extending from the dust pocket and opening in an end face in an axial direction in at least one of the half bearings and located downstream of the first linear groove in a rotating direction of the rotary shaft.
