Fluid Pressure Type Actuator

摘要

In order to improve its durability, a fluid pressure type actuator is comprises an expansible/contractible body having opposite ends sealed by plug members and expands/contracts when fluid is supplied to and discharged from the body; a wrapping body for wrapping the outer peripheral surface of the expansible/contractible body and having its opposite ends fastened and fixed to the plug members; an inlet/outlet for fluid formed in the plug members; and an auxiliary member for preventing or suppressing local deformation in which the wrapping body expands outward when the fluid is supplied to the expansible/contractible body.
