Zusammenfassung:	To provide a hydraulic actuator capable of firmly preventing malfunction caused by dropping off of a tube and a sleeve from a sealing member in a case in which high pressure is applied such as a case in which oil pressure driving is adopted. The hydraulic actuator 10 has a sealing mechanism 200. The sealing mechanism 200 has a sealing member 210 into which an actuator main portion 100 is inserted, a crimping ring 230 that binds the actuator main portion 100, and a locking ring 220 that locks a sleeve 120 to the sealing member 210. The sealing member 210 has a body portion 212, a head portion 211, and a flange portion arranged between the body portion 212 and the head portion 211. The flange portion 214 is protruded outward in a radial direction of the actuator main portion 100 more than the body portion 212.
