PROBLEM TO BE SOLVED: To provide a fluid feeding rotary joint in which hermetically-sealing performance can be improved, a high-speed revolution can be accepted and further a footprint can be decreased. SOLUTION: The fluid feeding rotary joint includes an outer race spacer member 31 which is arranged between two bearings for supporting outer and inner members in a relatively rotatable fashion and is fixed to the outer member and further is sandwiched between bearing outer rings 37, an inner race spacer member 33 which is fixed to the inner member and is arranged between the bearing inner rings 39 and with a gap provided radially in relation to the outer race spacer member 31, and a flexible ring-plate-shaped sealing member 35 which is sandwiched between the inner race spacer member 33 and the bearing inner rings 39 and whose peripheral portion is arranged with a gap provided radially in relation to the bearing outer race 37. The inner race spacer member 33 and the outer race spacer member 31 are provided with flow paths 43, 45, 49, 51, 53 penetrating radially to allow a fluid to flow, respectively.
