When a male member (132) is inserted into a female member (304) to connect a first joint portion (C1) of a hydraulic joint structure and a second joint portion (C2) thereof, a first open end portion (114a) of a first oil passage (114) of the male member and a first open end portion (306a) of a first oil passage (306) of the female member are connected at a first axial position, and a second open end portion (116a) of a second oil passage (116) of the male member and a second open end portion (308a) of a second oil passage (308) of the female member are connected at a second axial position. Thus, two hydraulic oil lines can be easily connected at the same time.
