PROBLEM TO BE SOLVED: To provide a device for storing a plurality of hydraulic hoses for operating a segment erector device for a shield machine without making them obstacles to eliminate the occurrence of twisting and damage of hydraulic hoses completely and satisfy a request for increasing the number of storage allowable hydraulic hoses. SOLUTION: A storage space A is peripherally provided by constituting it by a storage case A2 on rotary side consisting of an erector ring grater 3 and an erector flexible wire case 22 and a storage case A1 on fixed side consisting of a shield machine ring grater 5 and a shield machine flexible wire case 23. A plurality of flat flexible wires 21a for supply are divided and arranged on each half peripheral side A3, A4 of the storage space A between the storage case A2 on rotary side and the storage case A1 on fixed side, respectively, in storage partition layer rooms 25a, 25b partitioning the storage space A into a plurality of steps by partition plates 24a, 24b on rotary side and fixed side to bring them into pressure contact and nip them by a restoration force generated in folding-back parts B1, B2. A part 21d for leading the flexible wire for supply is led from the storage space A and is connected with a supply source 20 of a hydraulic tank.
