ABSTRACT:
Disclosed is a dynamic pressure gas bearing device in a rotational unit in which a rotational member put on a cantilevered fixed shaft is designed such that an operating gas generated by a dynamic pressure groove formed between the fixed shaft and the rotational member is directed into a pressure chamber between the fixed shaft and the rotational member and supports the rotational member in the thrust direction and that the pressure in the pressure chamber is adjusted by a hole formed in the fixed shaft or the rotational member.
