Abstract:
This spindle device (10) is provided with: a rotating shaft (12) provided with a plurality of turbine blades (11) that extend in the circumferential direction; a housing (20) that houses the rotating shaft (12); and a gas bearing (40) provided on the housing (20) and that, through the supply of a gas, floats and supports the rotating shaft (12) with respect to the housing (20) in a contactless manner, wherein the rotating shaft (12) rotates due to the gas being jetted onto the plurality of turbine blades (11).
