Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vane seal that reduces internal leakage of a rotary actuator.SOLUTION: A vane seal for a rotary actuator includes: a slide-contact ring 11 formed in the shape of an elongated rectangular closed ring and made of low-friction resin; and an elastic rubber material 12 with an outer circumferential surface covered with a slide-contact ring 11 and having a pressure-receiving recessed groove. The vane seal for the rotary actuator is mounted on a sealing recessed groove 8 which is straight in an axial direction and formed in a vane 6 on the side of a rotary main shaft 7 or a shoe on the side of a casing, and is formed in a belt-like shape as a whole.
