HYDRAULIC ACTUATOR

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 has a sealing mechanism. The sealing mechanism...

Beschreibung
Zusammenfassung:	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 has a sealing mechanism. The sealing mechanism has a sealing member into which an actuator main portion is inserted, a crimping ring that binds the actuator main portion, and a locking ring that locks a sleeve to the sealing member. The sealing member has a body portion, a head portion, and a flange portion arranged between the body portion and the head portion. The flange portion is protruded outward in a radial direction of the actuator main portion more than the body portion.
