The rotary tube shaft is fixed to a rear end portion of a spindle having a rotary coolant liquid flow path formed therein, and the internal rotary side flow path communicates with the rotary coolant liquid flow path, and The rear end surface of the rotary tube shaft is formed as a rotary-side sealing surface, and the floating seat is slidably supported in the axial direction by a joint body in which a fixed-side coolant liquid flow path is formed, and the floating seat is slidably supported in the axial direction by a joint body in which a fixed-side coolant liquid flow path is formed. A side flow path is communicated with the stationary side coolant liquid flow path, and a front end surface of the floating sheet is formed as a stationary side sealing surface, and the floating sheet slides forward so that the stationary side sealing surface becomes a rotating side. In a rotary joint in which a stationary side flow path and a rotating side flow path are connected by contacting a sealing surface, the rotary tube shaft is in a cantilevered state with no shaft support relative to the joint body, and the front end is attached to the spindle. A rotary joint characterized by being fixed to the rear end of the.
