Abstract
A lubricating device for a rolling bearing includes a lubricating oil introduction member () that has a discharge opening () opened to a circumferential groove () provided in an end face of an inner race () of a bearing (). A slope section () is provided on an outer peripheral surface of the inner race () and guides the lubricating oil in the groove () to a raceway surface () of the inner race () by centrifugal force and surface tension acting on the lubricating oil. The introduction member () is provided with a flange-like section () that overlays the slope section () with a minute gap δ between the flange-like section () and the slope section () and that controls the flow amount of the lubricating oil flowing through the gap δ to the raceway surface ().
