As shown in FIG. 3, the mesh packing is wound in a single layer in the longitudinal direction so that the side surfaces of the mesh packing adjacent to each other on the sheath 12 are brought into close contact with each other. Press both sides of it with the presser metal fittings 36 and 38 that have been inserted in the front. Reticulated packing 3
0 is wound in a spiral shape, so the end surfaces of the presser fittings 36 and 38 (the sides that contact the mesh packing 30) are also provided with spiral cut portions 360 and 380, like a part of a square screw, to form a mesh shape. Place it tightly on the side of the patch. Then, as before,
It is compressed by the compression spring 22 and the push screw fitting 24 (Fig. 4). The cross-sectional shape of the mesh packing 30 may be circular (FIG. 5), diamond (FIG. 6), triangular (FIG. 7), etc. in addition to the above-mentioned shapes. However, in the case of a triangular shape, as shown in Figure 8, it is necessary to wrap the other wire upside down to fill the valley.
