<p><P>PROBLEM TO BE SOLVED: To provide an air dynamic pressure bearing and an air blower of using this air dynamic pressure bearing, that can provide sufficient bearing rigidity, and can efficiently check the occurrence of inconvenience of influence by condensed moisture, by discharging the moisture of condensation generated in a herringbone type dynamic pressure generating groove from a straight type condensation preventive groove. <P>SOLUTION: This air dynamic pressure bearing forms the herringbone type dynamic pressure generating groove in a shaft or a sleeve. The air dynamic pressure bearing is constituted by forming at least one or more of straight type condensation preventive grooves on the side for increasing pressure of the herringbone type dynamic pressure generating groove and forming the dynamic pressure generating groove in the vicinity of an air-easily-condensing part. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
