These fitting projections 8 are arranged at equal intervals in the circumferential direction, and project in the axial direction from the sealing surface of the sealing surface member 5. In addition, a space between these fitting projections 8 is formed as a fitting recess 7, and when these joint bodies la and lb are abutted in the axial direction, one of the joint bodies The fitting projection 8 of 1a fits into the fitting recess 7 of the other fitting body 1b, and the fitting projection 8 of the other fitting body 1b fits the other fitting body 1a. It fits in the recess 7 and fits each other in a phase catching manner.
- the width of the fitting recess 7 is formed slightly wider than the width of the fitting projection 8. Therefore, the fitting projections 8 are fitted in the fitting recesses 7 in the axial direction, and are also rotatable by a predetermined amount in the circumferential direction.

Therefore, when these fitting projections 8 are fitted into the mating recesses 7 on the mating side as shown in FIG. 3, the steel balls 15 come into contact with each other and urge against each other. The other side surfaces of the fitting projections 8 are urged to move away from each other. As a result, one side surface of the fitting projections 8 is urged to approach each other, and as described above, The locking hooks 9 on one side are biased to engage with each other.
