Claims

[Scope of utility model registration request]

At least two screws are inserted closely into each other through a rotating shaft to which an actuator, etc. is fixed, and are fixed with a key.
It consists of a thick disk and a plate of the same thickness having a circular hole that is fitted on the outer periphery of each of the disks and is slidable in the circumferential direction. Two circumferential grooves are provided along the circumference, and a passage hole is provided at the intersection of a radius located equiangularly around the center of the end face and two concentric circles, and the passage hole on one radius is provided. have their other ends communicated with the circumferential grooves, passage holes on other radii are penetrated in the thickness direction of the disc, and two connection holes are opened on the outer periphery of each plate, The other end penetrates to the inner surface of the circular hole and communicates with the circumferential groove, and each plate is fixed to a bearing of the rotating shaft with a bolt, and depending on the combination of the relative positions of the discs, A rotary joint for piping, characterized in that a connecting passage for air, oil, etc. is formed of a passage hole, the circumferential groove, and the connection hole.
