Patent ID: 8714823

Claim:
A cylindrical sliding bearing comprising a pair of half bearings having abutment surfaces abutting against each other to form the cylindrical sliding bearing, the half bearings having inner circumferential surfaces formed as sliding surfaces, crush reliefs are formed on the inner circumferential surfaces of the half bearings at positions adjoining the abutment surfaces, so that lubricating oil is supplied to the sliding surfaces, the depth and length of the crush reliefs being set such that a relative angle formed by the crush reliefs and the sliding surfaces at positions adjoining the crush reliefs is at least 0.69 degrees, and a dust pocket for housing foreign substances provided inside the crush reliefs in a circumferential direction and configured by notched portions formed from inside the crush reliefs to an axial middle side of the abutment surfaces, wherein the axial size of the notched portions forming the dust pocket is set at 30-70% of the axial size of the abutment surfaces, the depth of the notched portions being set at a value at least equal to a maximum size of foreign substances mixed in the lubricating oil, foreign substances that are smaller than the depth of the crush reliefs are discharged to outside the sliding bearing through the crush reliefs and foreign substances larger than the depth of the crush reliefs mixed in the lubricating oil are housed in the dust pocket.
