<P>PROBLEM TO BE SOLVED: To provide a shaft sealing structure which does not present a decrease in shaft sealing capability due to a bend of a shaft. <P>SOLUTION: The shaft sealing structure includes first projections 6, 7, 8, 10, 11, 12, 15 that project toward a rotation shaft from a housing 1 enclosing the rotation shaft 3 with a clearance therefrom and forms annular seal surfaces 16 perpendicular to the rotation shaft 3, second projections 5, 6, 7, 9, 10, 13, 14 that project from the housing 1 toward the shaft and form support surfaces 17 opposed to the seal surfaces 16, seal rings 18 that are arranged between the first projections 6, 7, 8, 10, 11, 12, 15 and the second projections 5, 6, 7, 9, 10, 13, 14 and have an inner diameter slightly larger than the outer diameter of the shaft, and biasing members 19 that are arranged between the seal rings 18 and the support surfaces 17 and press the seal rings 18 against the seal surfaces 16. <P>COPYRIGHT: (C)2013,JPO&INPIT |
