To prevent leakage of a grout material from end portions of a bag body even if an internal pressure of the bag body is increased.
A pinching member 11 and a pinching member 12 constituting a bag body fixture 6 have core material insertion holes 17 and 20 individually formed on respective bottom portions 16 and 19 while being constituted of cylindrical walls 15 and 18 and the bottom portions 16 and 19 provided inside one ends thereof. On a wall cross section of the cylindrical wall 18, female screw holes 21 into which leading ends of bolts 14 are screwed along an axis of a member of the cylindrical wall 18 are formed while bolt insertion holes 26 through which the bolts 14 are inserted along an axis of a member of the cylindrical wall 15 are being formed on a wall cross section of the cylindrical wall 15. The bolts 14 are configured so as to be able to pinch each end portion peripheral 61 of a bag body 3 between the pinching member 11 and one end of an annular member 13 and between the other end of the annular member 13 and the pinching member 12, respectively, while relatively drawing each pinching member 11 and each pinching member 12 along an axis of a member of a core material 2.
