The formed bag-like portion 15 is positioned (the chain double-dashed line in FIG. 3B). At this time, or in advance, the other portion of the bag-like portion 15 is internally provided with a cord body 25 having a small cross-sectional area in the flange 15b. The rope body 25 is a flexible long material such as a tape, a rope, or a wire.

  Next, the other portion of the bag-like portion 15 is inserted into the gap 14 between the left and right support members 12 and 12 with the wrinkles 15b flattened (solid line in FIG. 3B).

  Next, after connecting one end portion of the interior body 16 to one end portion of the strip body 25 outside the bag-shaped portion 15, the other end portion of the strip body 25 is pulled, The other part of the bag-like part 15 is pulled out from the wrinkle 15b. Then, the inner body 16 is inserted into the other portion 15b of the bag-like portion 15. As a result, the outer width dimension W of the cross section of the other portion 15 b of the bag-shaped portion 15 is made larger than the inner width dimension w of the gap 14. And the other part of the said bag-shaped part 15 expanded by insertion of the said interior body 16 arrange | positions the wrinkle 15b over the said left and right support materials 12 and 12 (FIG. 1, 2).

  Next, by applying tension to the film body 3, the other portion of the bag-like portion 15 inserted through the interior body 16 supports the wrinkles 15 b on the left and right support members 12 and 12. If the film body 3 is tensioned in this way, the film body 3 is stretched with respect to the stationary member 2.

  According to the above configuration, the film body 3 is arranged in parallel in the surface direction of the film body 3 between the middle part 3a of the film body 3 and the long body 9, and extends in parallel with each other along the long body 9. A pair of left and right support members 12, 12 attached to the body 9, a gap 14 formed between the left and right support members 12, 12, and a line of sight along the longitudinal direction of the long body 9 ( FIG. 1) A flexible bag having a bag shape, a part 15a in the circumferential direction being joined to the middle part 3a of the film body 3 and a part 15b in the other circumferential direction being inserted into the gap 14. And the other part of the bag-like part 15 is inserted into the flaw 15b, and the other part of the bag-like part 15 has the outer width dimension W of the cross-section of the flaw 15b. 14 and an interior body 16 that is larger than the inner width dimension w.

  For this reason, the left and right support members attached to the long body 9 during the attachment work of the middle part 3a of the film body 3 to the long body 9 of the fixed-side member 2 using the film body attachment structure 4 having the above configuration. 12, the other part of the bag-like part 15 attached to the middle part 3a of the film body 3 is inserted into the gap 15b, and then the other part of the bag-like part 15 is inserted into the jaw 15b. The inner body 16 is inserted, and the other portion of the bag-like portion 15 whose outer width W is expanded by the insertion of the inner body 16 supports the wrinkles 15b so as to straddle the left and right support members 12, 12. Just do it.

  Therefore, compared to the conventional technique in which the middle part 3a of the film body 3 is attached to the long body 9 using a rope racking or a metal fastener member, the processing to the film body 3 side is performed. As a result, the film body 3 side can be easily processed, and the middle part 3a of the film body 3 can be easily and smoothly attached to the long body 9. Further, the distance between the film body 3 and the elongate body 9 can be shortened as compared with that using the metallic fastener member described in the prior art. It is prevented that the space is unnecessarily narrowed.

  Moreover, as described above, the other end portion in the circumferential direction of the bag-like portion 15 has a flat shape in a free state in which the inner body 16 is not inserted.

  For this reason, at the time of attaching the intermediate part 3a of the film body 3 to the fixed side member 2 described above, the work of inserting the wrinkle 15b of the other part of the bag-like part 15 into the gap 14 can be made easy and smooth. it can.

  Further, as described above, when viewed from the line of sight along the longitudinal direction of the bag-like portion 15 (FIG. 3A), the bag-like portion 15 is perpendicular to the surface direction of the middle portion 3 a of the film body 3 and the bag-like portion 15. When the virtual straight line 23 passing through the portion 15a in the circumferential direction is set, in the free state of the bag-shaped portion 15 (FIG. 3A), the other portion 15b of the bag-shaped portion 15 is the virtual straight line 23. And are inclined with respect to the imaginary straight line 23.

  For this reason, at the time of attaching the middle part 3a of the film body 3 to the fixed side member 2 described above, the other part of the bag-like part 15 has a gap 15b in the gap 14 between the left and right support members 12, 12. When inserted, this other part can be easily pressed lightly against the support member 12 of at least one of the left and right support members 12, 12. And if it does in this way, the other part of the said bag-shaped part 15 can be positioned with respect to said one support material 12 so that the wrinkle 15b may be maintained in a fixed attitude | position (FIG.3 (b)).

  Therefore, after that, when the other part of the bag-like portion 15 allows the inner body 16 to be inserted into the wand 15b, the other part is connected to the ward 15b as compared to the other part 15b being in a free state. The insertion work of the inner body 16 can be facilitated, and thereby the attachment work of the middle part 3a of the film body 3 to the long body 9 can be performed more easily and smoothly.

  Further, as described above, a plurality of left and right attachment pieces 13 and 13 are provided in the longitudinal direction of the long body 9 to attach the left and right support members 12 and 12 to the long body 9, respectively. The attachment pieces 13 are arranged in a staggered manner in the longitudinal direction of the long body 9.

  Here, at the time of attaching the middle part 3a of the film body 3 to the fixed side member 2 described above, the other part of the bag-like part 15 is inserted into the gap 14 and the other part is installed in the ward 15b. When the body 16 is inserted, the space between the elongate body 9 and the left and right support members 12 and 12 becomes a work space 26 for each of the insertion operations.

  In the above case, when an operator inserts a hand or a tool from the left or right outer side to the partial area of the work space 26 in the longitudinal direction of the long body 9, Since the left and right mounting pieces 13 and 13 are arranged in a staggered manner as described above, the insertion and the insertion can be performed easily and smoothly while avoiding at least one of the left and right mounting pieces 13 and 13. Insertion work can be done. Therefore, also in this point, the attachment work of the middle part 3a of the film body 3 to the long body 9 can be performed more easily and smoothly.

  Further, as described above, the bag-like portion 15 extends in the longitudinal direction so as to constitute a portion 15 a of the bag-like portion 15, and is bonded to the middle portion 3 a of the film body 3 with the belt-like base material 20. The bag-like portion 15 extends in the longitudinal direction so that the other portion of the bag-like portion 15 constitutes the flange 15 b, and the cross-section of each portion in the longitudinal direction forms an annular shape, and a portion in the circumferential direction is fixed to the base material 20. The base body 20 and the bag-shaped part main body 21 are integrally woven into a three-dimensional fabric.

  For this reason, when forming the bag-like portion 15, if the base material 20 and the bag-like portion main body 21 are individually formed, the bag-like portion 15 is formed by combining these 20 and 21. In contrast, according to the above-described configuration, the base material 20 and the bag-shaped portion main body 21 are integrally woven to form the bag-shaped portion 15 having a high strength easily and smoothly. . Therefore, the work of attaching the middle part 3a of the film body 3 to the long body 9 can be performed more easily and smoothly.

  Further, as described above, a resin that can be welded to the film body 3 is provided on at least the surface of the outer surface of the base material 20 that is surface-bonded to the middle portion 3 a of the film body 3.

  For this reason, joining of the film body 3 and the bag-like portion 15 can be performed by heat welding. According to such heat welding, the bag-like portion 15 is more firmly attached to the film body 3. It can be firmly and integrally joined together.
