Abstract: A static pressure-type generating non-contact gas seal in which a diameter d2 of a second outer circumferential portion (42) of a stationary seal ring (4) in contact with a second O-ring (62) is made smaller than the diameter d1 of a first outer circumferential portion (41) of the stationary seal ring (4) in contact with a first O-ring (62). Because of d1>d2, the pressure of a seal gas (8) led to a first closed space (71) produces a force thrusting the stationary seal ring (4) toward a rotary seal ring (2). A second closed space (72) communicates with an inside region (F) through a back pressure lead-in path (45). The inside gas pressure in the second closed space (72) acts as back pressure on the stationary seal ring (4). The groove width b of static pressure generating grooves (9) formed on the seal end face of the stationary seal ring (4) is decided so that a ratio of the groove width d to the radial width, that is, the seal face width B of the stationary seal ring end face (40), i.e. b/B, is 0.05.
