Abstract:
When a male member is inserted into a female member to connect a first joint portion of a hydraulic joint structure and a second joint portion thereof, a first open end portion of a first oil passage of the male member and a first open end portion of a first oil passage of the female member are connected at a first axial position, and a second open end portion of a second oil passage of the male member and a second open end portion of a second oil passage of the female member are connected at a second axial position. Thus, two hydraulic oil lines can be easily connected at the same time.
