ABSTRACT:
A lubricating device for a rolling bearing includes a lubricating oil introduction member (7) that has a discharge opening (8) opened to a circumferential groove (6) provided in an end face of an inner race (2) of a bearing (1). A slope section (2b) is provided on an outer peripheral surface of the inner race (2) and guides the lubricating oil in the groove (6) to a raceway surface (2a) of the inner race (2) by centrifugal force and surface tension acting on the lubricating oil. The introduction member (7) is provided with a flange-like section (10) that overlays the slope section (2b) with a minute gap δ between the flange-like section (10) and the slope section (2b) and that controls the flow amount of the lubricating oil flowing through the gap δ to the raceway surface (2a).
