Title:
FLUID PRESSURE ACTUATOR
Document Type and Number:
Japanese Patent JP2023084864
Kind Code:
A
Abstract:
To provide a fluid pressure actuator improved in recyclability while using a structure caulking an actuator body portion to a sealing member using a ring-shaped restraining member.SOLUTION: A sealing mechanism of a fluid pressure actuator 10 is equipped with a sealing member into which an actuator body portion 100 is inserted, a caulking ring 230 that is provided on an outer peripheral surface of the actuator body portion 100 inserted into the sealing member and retrains the actuator body portion 100, and a locking ring 220 that locks a sleeve 120 to the sealing member. The sealing member has a body portion 212 into which a tube 110 is inserted, and a head portion 211 that is provided outside the body portion 212 in an axial direction and is separated from the body portion 212. The locking member is provided on an outer end in the axial direction of the body portion 212, and on the head portion 211 and the body portion 212, an insertion hole in the axial direction is formed. The head portion 211 and the body portion 212 are fixed by a bolt 240 inserted into the insertion hole.SELECTED DRAWING: Figure 3
