PROBLEM TO BE SOLVED: To provide a bearing superior in lubricant retaining force, in initial familiarity while suppressing the oozing amount of lubricant to a required minimum even when subjected to deformation due to external force, and in productivity while achieving a longer life and lower cost. SOLUTION: Grease or initial lubricant 37 as lubricating oil and foamed lubricant 38 exist in the bearing 31. The foamed lubricant 38 contains a lubricating component in a resin foamed and hardened into a porous form. In initial lubrication of the bearing 31, the initial lubricant 37 exists in a rolling portion and a sliding portion of the bearing 1. COPYRIGHT: (C)2008,JPO&INPIT
