Abstract

A rotary actuator 1 is driven in rotation by pressurized gas supplied by a gas generator 2 and drives a belt take-up reel (R9, Fig 2). A partition wall 112 that separates the pressure section 102A of the operating chamber 102 from the exhaust section 102B receives a seal member 13, which is resiliently urged by a spring 14 into engagement with the body portion (122, Fig 3) of rotor 12. The seal member prevents gas from leaking past the partition wall from the pressure section to the exhaust section. <IMAGE>
