たことを特徴とする回転体軸受装置。 A rotating body such as an idler pulley that is rotatably supported on the shaft via a bearing, a grease pocket within the rotating body that is limited by the shaft, the bearing, and the rotating body, and a grease pocket provided within the shaft and at one end thereof. a grease supply passage provided with a grease nipple and an escape valve at the other end; an oil hole provided within the shaft that communicates the grease pocket with the grease supply passage; and a grease between the grease nipple and the oil hole. A flow rate adjustment section formed in the supply passage is provided, and passage resistance when the grease flows from the grease supply passage through the oil hole into the grease pocket and passage resistance when the grease passes through the flow rate adjustment section are approximately equal to each other. A rotating body bearing device characterized in that it is set to be equivalent.
