Zusammenfassung:	PURPOSE:To forcedly lubricate an underwater bearing to enhance the lubrication of the bearing, by determining the dimensions and shapes of two spatters such that a difference is effected between water pressures at both ends of the underwater bearing. CONSTITUTION:When spatters 11, 11' rotate in association with the rotation of a pump shaft 1, water between the spatters and a bearing support 7 creates a swirl stream under action of radial blades 11b, 11b' of the spatters. The dimentions of the radial blades 11b, 11b' are set such as Do>Do' in outer diameter, and Di=Di' in inner diameter, and therefore, the drop in static pressure around the underwater bearing, caused by the blades 11b is larger than that by the blades 11b', that is, PX
