Zusammenfassung:	PROBLEM TO BE SOLVED: To secure rigidity, and also shorten a radial length.SOLUTION: In a rotary joint 10, a first circumferential groove (first compressed air supply groove 34, first pressure oil supply groove 36, first coolant supply groove 38) formed on a first slide surface 28, and a second circumferential groove (second compressed air supply groove 48, second pressure oil supply groove 50, second coolant supply groove 52) formed on a second slide surface 30 are formed oppositely in a view from a radial direction of the rotary joint 10. In this case, the opposite pair of the first circumferential groove and second circumferential groove has the same kind and use application of fluid flowing in the respective circumferential grooves.SELECTED DRAWING: Figure 1 【課題】剛性を確保しつつ、径方向の長さを短くする。【解決手段】ロータリージョイント１０において、第１摺接面２８に形成された第１円周溝（第１圧縮空気供給溝３４、第１圧油供給溝３６、第１クーラント供給溝３８）と、第２摺接面３０に形成された第２円周溝（第２圧縮空気供給溝４８、第２圧油供給溝５０、第２クーラント供給溝５２）とは、ロータリージョイント１０の径方向から見て、対向するように形成されている。この場合、対向する１組の第１円周溝及び第２円周溝は、該各円周溝の中を流れる流体の種別及び使用用途が同じである。【選択図】図１
