Claims

[Claims for Utility Model Registration] A shaft body in which a plurality of fluid passages are formed; an annular body that is fitted to the outer periphery of the shaft body so as to be relatively rotatable and in which a plurality of fluid passages are formed; a plurality of circumferential grooves formed between the annular bodies to be spaced apart in the axial direction and communicating the fluid passages of the corresponding shaft bodies and the fluid passages of the annular body, and through the circumferential grooves; In the relative rotating body structure in which fluid movement is performed between both the fluid passages, a sealing member between the shaft body and the annular body is spaced apart in the axial direction between the circumferential grooves that are adjacent to each other. A passage arrangement structure between relative rotating bodies, characterized in that a pair of seal members are provided, and a drain passage is formed between the pair of seal members.
