Title: Dynamic pressure bearing
Inventor: SHIMURA SHOICHI
IPC: F16C17/02
Filed: 2001-05-23
Abstract: PROBLEM TO BE SOLVED: To solve the problem that an oil interposed in a fine gap of a dynamic pressure bearing is leaked out and a desired characteristic cannot be obtained in the case where the oil having a low viscosity is generally used as the oil of the dynamic pressure bearing, particularly in the case where the dynamic pressure bearing is used in an inclineded condition.
