ACTUATOR AND BODY ASSISTANCE DEVICE

摘要

[Problem] To provide a McKibben actuator with which it is possible to generate similar or greater contractive force with less pressure than prior actuators. [Solution] A McKibben actuator (10) configured from an inner tube (11) that expands when pressurized, and an outer sleeve (12) that covers the outer surface of the inner tube (11) and restricts the expansion of the inner tube (11), the diametral expansion of the inner tube (11) being converted to lengthwise contraction by the outer sleeve (12); wherein the inner tube (11) is formed from an elastic material having an elongation percentage of 100% or more.
