A foil type dynamic pressure gas bearing capable of providing excellent bearing performance by using a spring foil easily manufacturable and having excellent productivity and a dynamic pressure gas bearing capable of eliminating a restriction in a rotating direction by using an easily installable top foil fixing structure. The spring foil (12) formed of an elastic thin flat plate having a plurality of slits (16) is fitted to the inside wall of a bearing housing (11), a top foil (13) is disposed on the inside of the spring foil, and a rotating shaft (14) is disposed on the inside of the top foil. The spring foil (12) is bent at the positions of the slits (16) to form a large number of elastic beams in contact with the inside of the inside wall, and the rotating shaft (14) is elastically supported by the elastic beams. |
