  • the locking tooth 49 closest to the tip end side of the band portion 40 is inserted into the insertion passage 25 of the lock portion 20.
  • the locking piece 30 is flexed and deformed by contacting the locking claw 32 that is away from the bending fulcrum P1 of the locking piece 30. Therefore, it is possible to secure a long distance L between the fulcrum P1 of the locking piece 30 at the time of flexural deformation and the action point P3 of the locking claw 32 to which the pressing force is applied from the most distal locking tooth 51. Therefore, the locking piece 30 can be easily bent, and the insertion force of the band portion 40 can be reduced even after the most distal locking teeth 51 have passed.
  • the most distal locking teeth 51 are the first inclined surface 59 located on the tip end 43 side in the extending direction of the band portion 40 and the extending direction of the band portion 40 with respect to the first inclined surface 59.
  • a stepwise protruding portion is provided via the first inclined surface 59 and the second inclined surface 61.
  • the amount of protrusion of the shelf surface 63 provided between the first slope 59 and the second slope 61 from the one surface 45 of the band portion 40 is constant. Therefore, the band portion 40 can be temporarily held in a stable manner.
  • the length C of the shelf surface 63 along the extending direction of the band portion 40 is the length C of the band portion 40 of the most distal locking tooth 51.
  • the apex portion 54 having a constant amount of protrusion from the one surface 45, or the inclined portion 54a inclined from the apex portion 54 of the most distal locking tooth 51 toward the distal end 43 side in the extending direction of the band portion 40 see FIG.
  • the length C of the shelf surface 63 is ensured to be long because it is formed so as to be larger than the length D along the extending direction of the band portion 40 (see the chain double-dashed line in the partial enlarged view of b)). Therefore, the band portion 40 can be temporarily held more stably.
  • a pair of projecting support portions 27, 27 is provided inside the insertion passage 25 of the lock portion 20 (see FIG. 7), and is orthogonal to the extending direction of the band portion 40.
  • a pair of ribs 47, 47 supported by the pair of projecting support portions 27, 27 are provided on both side portions in the width direction.
  • the structure is such that the stop teeth 51 are arranged (see FIG. 3A). Therefore, when the band portion 40 is inserted into the insertion passage 25 of the lock portion 20, the pair of ribs 47, 47 is supported by the pair of projecting support portions 27, 27, and the band portion 40 is prevented from rattling and the band portion 40 is suppressed.
  • the locking piece 40 can be aligned in the direction away from the locking piece 30, and the inclined surface of the most advanced locking tooth 51 can be easily brought into contact with the middle portion of the locking claw 31 of the locking piece 30 in the protruding direction. (As shown in FIGS. 4A and 4B, the first inclined surface 59 and the second inclined surface 61 of the most distal locking tooth 51 can be easily brought into contact with the tapered surface 31a of the locking claw 31.) Therefore, it is possible to more appropriately reduce the insertion force of the band portion 40.
  • the present invention is not limited to the above-described embodiments, and various modified embodiments are possible within the scope of the gist of the present invention, and such embodiments are also included in the scope of the present invention. ..

Abstract

L'invention concerne un collier à bande qui peut réduire une force d'insertion d'une partie de bande dans un passage d'insertion d'une partie de verrouillage. Ce collier à bande (10) dispose d'une partie de verrouillage (20) et d'une partie de bande (40), la partie de verrouillage (20) dispose d'un passage d'insertion (25) et d'une pièce de verrouillage (30) ayant des griffes de verrouillage (31) et (32), et la partie de bande (40) dispose d'une pluralité de dents de verrouillage. Lorsque la longueur, d'une partie de bord (53) à une partie supérieure (54), d'une dent de verrouillage la plus en avant (51) située sur un côté le plus en avant de la partie de bande est A, et la longueur, de la partie de bord (53) à la partie supérieure (54), d'une dent de verrouillage (49) adjacente à la dent de verrouillage la plus en avant est B, a est supérieur à B, et la dent de verrouillage la plus en avant (51) est disposée entre la partie de bord (53) et la partie supérieure (54) de façon à faire saillie avec une pente intermittente.
