摘要

PROBLEM TO BE SOLVED: To provide a halved slide bearing in which a foreign matter is hard to be accumulated on a slide surface and lubricant is hard to be leaked from a joint part.SOLUTION: A slide bearing 1 includes a first bearing member 10 and a second bearing member 50 that are a pair of members constituting a halved bearing. A groove 15 extending in a slide direction is included on a slide surface 12 of the first bearing member 10. The width of the groove 15 becomes a maximum value at a position between two joint parts 13 joining the first bearing member and the second bearing member, and is continuously reduced as approaching the joint parts 13.
