Claims

[Scope of utility model registration request]

The inner diameter side of the outside body fixed to the cutter face side of the rotary joint for discharging stable liquid from the front side of the cutter face, which is arranged on the back side of the cutter face, or the outer diameter side of the inside body fixed to the shield body side. A local stable liquid passage groove is provided at a predetermined location on the side circumferential surface to communicate with the stable liquid discharge port of the cutter face, and as the cutter face rotates, the stable liquid passage groove is disposed on the inside body. A shield type tunnel excavator characterized in that a stabilizing liquid is supplied to a stabilizing liquid supply port of a cutter face only when communicating with a stabilizing liquid supply hole provided in the cutter face.
