Abstract
Provided is a slide bearing capable of sustaining sliding performance over long period. A slide bearing has an upper case () configured to be attached to an upper support for attachment of a suspension to a vehicle body, a lower case () rotatably combined with the upper case () to form an annular space (); and an annular center plate () and an annular sliding sheet () both placed within the annular space (). The center plate () includes a bearing surface () slidable with the sliding sheet () and an annular groove () formed on the bearing surface () so as to hold lubricant. The annular groove () has an inner circumferential surface () inclining down from the opening section toward the groove bottom section as it goes outwardly in the radial direction and an outer circumferential surface () inclining down from the opening section toward the groove bottom section as it goes inwardly in the radial direction. A line P of intersection between the inner circumferential surface () and the outer circumferential surface () is located closer to the bearing surface () than to a back face () of the center plate ().
