PROBLEM TO BE SOLVED: To provide a lubricating device of a rolling bearing having an inner ring cooling function capable of sufficiently suppressing the rise of the temperature of an inner ring. SOLUTION: A cooling oil introduction member 12 having a nozzle 16 jetting a cooling oil partly used as a lubricating oil in the bearing to the tapered surface 2b of the inner ring 2 is disposed on the rear surface of the angular ball bearing 1. A cooling oil introduction member 11 having a nozzle 13 jetting a cooling oil to a circumferential groove 6 formed in the end face of the inner ring 2 is disposed on the front side of the angular bearing 1 to cool the inner ring by the cooling oil from the axial both sides thereof. Consequently, the lubricating device can comprise the cooling function for the inner ring 2 capable of sufficiently suppressing the rise of the temperature of the inner ring 2.
