Claims

[Claims for Utility Model Registration] (1) A bearing, a fixed part that fits and holds the bearing on the inner circumferential side, a rotating shaft located on the inner circumferential side of the bearing, and the bearing among the rotating shafts. The oil hole is formed at a position that opens on one side, and the oil flow that is located on one side of the bearing on the outer circumferential side of the oil hole and jets out from the oil hole in the approximately radial direction of the rotating shaft is described above. A lubrication structure for a bearing, comprising an oil guide having a guide surface that directs the flow toward the bearing. (2) The oil guide is an annular piece that is formed integrally with the fixed part and extends from the part that holds the bearing to a position that covers the opening of the oil hole on one side of the bearing, The bearing lubrication structure according to claim 1, wherein the guide surface is formed on the inner surface of the annular piece facing the bearing. (3) The bearing has a structure in which rolling elements are arranged between an outer ring and an inner ring, and the guide surface extends from the inner periphery of one side of the outer ring to guide oil between the outer ring and the inner ring. The lubrication structure for a bearing according to claim 1, characterized in that the structure is an inclined surface extending at a predetermined angle with respect to the axial direction.
