進機の中折れ部シール装置。[Scope of Claim for Utility Model Registration] 1. Inside a shield excavator in which a part of the front body of the shield and a part of the rear body of the shield are slidably overlapped with each other via a seal to form a center folded part. In the folded part sealing device, the seal is a hollow body made of a flexible material, formed in a cross-sectional shape having a protrusion at the center of its abdomen, and attached to the seal mounting part so that the protrusion comes into contact with the seal sliding surface. A sealing device for the folded part of a shield excavator, which is characterized by: 2 A plurality of the seals having pressurized fluid injection holes into the hollow parts are attached to the seal mounting part, and the pressurized fluid injection holes are inserted into the seal mounting part through pockets provided between the seals. 2. The folded portion sealing device for a shield tunneling machine according to claim 1, wherein the sealing device is connected to a pressurized fluid supply port.
