Abstract
PURPOSE: To improve the bearing rigidity checking infiltration of air into an axial drain groove by means of a drain hole drilled on the second circular drain groove in such a manner as to have the lower end thereof opened at the upper most portion from a gravitational point of view and the upper end opened to the open air.
CONSTITUTION: When fed to the supply passage, the pressure fluid is supplied to a groove-shaped pocket 15 through a throttle 21 so that an even oil film is formed on the land 16, while it properly flows to an axial discharge groove 17 and circular discharge 18 and 19 through a clearance between the belt-shaped land formed around the pocket 15 and the circumference of the shaft member. The fluid flowing out to the circular discharge groove 19 provided at the center C of the shaft is discharged from the upper open end of a discharge hole 19a provided at the upper most part. Accordingly, the fluid fills the groove 17 and the groove 19 thereby preventing infiltration of air thereinto.
