  • the hidden slide fastener 1 has a gap formed between the U-shaped bent portions 2 c of the left and right fastener tapes 2 even when a lateral pulling force is applied to the left and right fastener tapes 2. Since it can be made significantly smaller than the conventional hidden slide fastener 1 or the formation of the same gap can be prevented, excellent concealability can be stably maintained.

  • a concave groove 34 is formed on the element facing surface 12b disposed in the front-rear direction so as to face the adjacent fastener element 32, and the first leg facing surface. It is formed continuously from the second sewing thread holding groove 15 of 12a.
  • each fastener element 32 of the third embodiment has the second sewing for accommodating and holding the second looper thread 9b by forming the concave grooves 34 in both the front and rear element facing surfaces 12b.
  • the dimension of the thread holding groove 15 in the tape length direction is shorter than the dimension of the meshing head 13 in the tape length direction. For this reason, the space
  • the second looper thread is formed by forming the concave groove 34 in the element facing surface 12b of the fastener element 32 as described above and increasing the interval between the second sewing thread holding grooves 15 of the adjacent fastener elements 32.

  • the interference with the meshing head 13 can be further reduced.
  • the left and right element rows 3 can be meshed firmly and stably, and the concealing property of the hidden slide fastener 21 can be further improved.
  • the fastener element 32 of the third embodiment protrudes in the front-rear direction (tape length direction) on the element facing surfaces 11b, 12b at the meshing head side ends of the first and second leg portions 11, 12.
  • a portion 33 is provided.
  • the protrusion 33 has a rectangular shape when the fastener element 32 is viewed from the front-rear direction (tape longitudinal direction). Since each fastener element 32 has such a protrusion 33, the position of the second looper thread 9b can be more reliably prevented from shifting to the meshing head side.
  • the fastener tape 2 receives a lateral pulling force, and the fastener element 32 becomes a U-shaped bent portion of the fastener tape 2. Even if the fastener element 32 collides with the protruding portion 33 on the meshing counterpart side even when trying to rotate in a direction to return 2c straight, it is possible to prevent the fastener element 32 from rotating. For this reason, the clearance gap formed between the U-shaped bending parts 2c of the right and left fastener tape 2 can be made smaller, and the concealment property of the hidden slide fastener 21 can be further improved.
  • FIG. 13 is a main part external view showing the element row in the engaged state in the hidden slide fastener of the fourth embodiment
  • FIG. 14 is a cross-sectional view showing the engaged state of the hidden slide fastener.
  • the hidden slide fastener 41 of the fourth embodiment is similar to the hidden slide fastener 31 of the third embodiment in that the element-facing surface of the engagement head side end portions of the first and second leg portions 11 and 12 of each fastener element 42. 11b, 12b has a protruding portion 43 protruding in the front-rear direction (tape length direction).
  • the shape of the protruding portion 43 is different from that of the third embodiment, and when the fastener element 42 is viewed from the tape length direction, the shape of the protruding portion 43 is the first leg portion 11 (or the second leg portion 12). ) From the outer surface to the second leg-facing surface (or the first leg-facing surface 12a), the one surface on the side of the meshing head 13 is on the opposite side (the leg extending end). It is formed in a substantially trapezoidal shape inclined with respect to the other surface.
  • the hidden slide fastener 41 of the fourth embodiment is basically the same as the hidden slide fastener 31 of the third embodiment, except for the configuration of the protruding portion 43.
  • the fastener tape 2 exerts a lateral pulling force. Even if it receives, it can suppress that the fastener element 42 rotates so that the U-shaped bending part 2c of the fastener tape 2 may be returned straight.
  • the hidden slide fastener 41 of the fourth embodiment is formed so that the protruding portion 43 has a substantially trapezoidal shape as described above when viewed from the tape length direction.
  • the meshing head 13 on the meshing partner side can be appropriately collided with one surface of the projecting portion 43 on the side of the meshing head 13 inclined. For this reason, rotation of the fastener element 42 can be more reliably suppressed, and the gap formed between the U-shaped bent portions 2c of the left and right fastener tapes 2 can be further reduced.
  • FIG. 15 is a perspective view of the main part showing only the fastener element in the hidden slide fastener of the fifth embodiment.
  • a plurality of single fastener elements 10 in the hidden slide fastener 1 of the first embodiment are continuously formed in a zigzag shape instead of being sewn to the element mounting portion 2b.

  • 52 has a connecting portion 64 connected to the first leg portion 61 or the second leg portion 62, the second leg portion 62 is in contact with the element mounting portion 2 b of the fastener tape 2, and the first leg portion 61 is sewn to the element mounting portion 2b in a posture separated from the fastener tape 2.
  • a concave second sewing thread for accommodating and holding the second sewing thread 9 at a position on the side of the meshing head 63 of the first leg portion facing surface 62a of the second leg portion 62 in each fastener element 52.
  • a holding groove 65 is formed.
  • the second sewing thread holding groove 65 is formed so that the groove width is wider than the sectional diameter of three looper threads and the groove depth is larger than the sectional diameter of one looper thread.
  • first sewing thread 8 for sewing the fastener element 52 is arranged on the outer surface side of the first needle thread 8a and the first leg 61, and is formed at a position between the fastener elements 52 while forming a loop.
  • the connecting portion side of the first and second leg portions 61 and 62 of 52 is sewn to the element mounting portion 2b.
  • the second sewing thread 9 is disposed on the second leg thread 9a and the first leg facing surface 62a side of the second leg 62, and the second needle 9 is formed at a position between the fastener elements 52 while forming a loop.
