  Further, as shown in FIG. 8, the anchor plate 30 in the present embodiment includes a curved portion 62 that is curved so that a portion disposed in the boot 40 is separated from the floor panel 16 in a side sectional view of FIG. 8. Has been. The curved portion 62 has slit-like through holes 32 and 33 formed on both sides of the top portion, and the webbing is formed in the through holes 32 and 33 so that the webbing 28 is folded back below the top portion of the curved portion 62. 28 is inserted. In the anchor plate 30, the front end side (left side in FIG. 8) of the curved portion 62 is a flat plate portion 64 disposed on the floor panel 16. As shown in FIGS. 8 and 10, the abutment surface 45 </ b> A of the front portion 340 of the boot 40 described above is abutted against the upper surface 31 of the flat plate portion 64.

  In the anchor plate 30, the front end side (left side in FIG. 8, upper side in FIG. 10) of the anchor plate 30 is grasped as a restriction wall portion 66 (broadly defined as “support means”) that is bent at a substantially right angle. Is extended). As shown in FIG. 8, the regulation wall portion 66 is in contact with a wall portion facing portion 49 that is a part of the outward surface on the base end 40 </ b> B side of the front portion 340 of the boot 40 in the fixed state of the boot 40. The wall facing portion 49 is supported. The support structure 68 in which the restriction wall portion 66 supports the wall portion facing portion 49 of the boot 40 restricts displacement of the boot 40 relative to the anchor plate 30 (displacement to the side opposite to the fixed end 30C side (left side in FIG. 8)). It constitutes the regulation means.

  Next, a boot fixing method applied to fixing the boot 40 of the buckle device 60 will be briefly described. The first step is the same as in the first embodiment. In the second step, the boot 40 is rotated in a direction to stand on the upper surface 31 side of the anchor plate 30, and the flat plate portion 64 and the regulating wall portion 66 of the anchor plate 30 are also extracted from the boot 40, and the base end 40 </ b> B of the boot 40 is extracted. The two end surfaces 46 (that is, the contact surface 44 </ b> A of the back portion 140 and the contact surface 45 </ b> A of the front portion 340) abut against the upper surface 31 of the anchor plate 30. In this second step, a plurality of locations on the base end 40B side of the boot 40 including the contact surfaces 44A and 45A are arranged at positions in contact with the anchor plate 30, and the anchor plate 30 is formed by the fitting structure 50 and the support structures 52 and 68. The displacement of the boot 40 with respect to is regulated.

  As described above, according to the buckle device 60 and the boot fixing method according to the present embodiment, the sewing of the boot 40 to the webbing 28 can be eliminated with a simple configuration.

[Supplementary explanation of the embodiment]
In the first and second embodiments (see FIGS. 2 and 7), the claw portion 36 is fitted into the fitting hole 42 and the fitting recess 56 from the inside of the boot 40 at a position away from the floor panel 16. However, the nail | claw part may be fitted by the fitting part from the outer side of boots in the position away from the floor part, for example.

  In the above embodiment, as shown in FIGS. 5 and 10, the width dimension 30L of the anchor plate 30 along the width direction (arrow 28W direction) of the webbing 28 is equal to the width direction of the webbing 28 (arrow 28W direction). The inner diameter width dimension 40L of the boot 40 is set to be smaller than that of the boot 40, and such a configuration is preferable for assembling the boot 40. However, the width dimension of the anchor member along the width direction of the webbing is, for example, that of the webbing. It may be set to the same dimension as the inner diameter width dimension of the boot along the width direction, or may be set to a dimension larger than the inner diameter width dimension of the boot along the width direction of the webbing. For example, the boot is formed in a substantially rectangular tube shape (for example, the same shape as in the above embodiment), and the width dimension of the anchor member along the width direction of the webbing is the inner diameter width dimension of the boot along the width direction of the webbing. When the size of the anchor member is set to a larger dimension, when the boot is fixed, the insertion position of the anchor member into the boot is viewed from the penetration direction of the boot (in other words, as viewed in the direction in which the anchor member passes). The posture may be inclined with respect to the inner wall plane (for example, the diagonal direction of the inner wall of the boot as viewed in the penetration direction of the boot).

  Furthermore, in the said embodiment, as FIG. 2 etc. show, although the anchor plate 30 is being fixed directly to the floor panel 16, an anchor plate (anchor member) is a floor panel (floor part) via another member. It may be fixed to.

  Furthermore, the boot is only required to maintain the standing posture with respect to the anchor member by supporting at least one portion on the other end side by the anchor member. It is not limited to examples. In addition, a supplementary description will be given of a configuration in which the other end side of the boot is supported by the anchor member at one location. For example, the boot has a contact surface in which the entire end surface of the other end is abutted against the upper surface of the anchor member. It may be a boot in which the entire end face of the end is supported by the anchor member so that the standing posture is maintained with respect to the anchor member. As another modification, the boot is formed in, for example, a substantially rectangular tube shape, and a plurality of continuous side portions (for example, the end surface at the other end of the back portion 140 in the above embodiment and the other end surface) The two sides that are substantially L-shaped, such as the end surface of the other end of the side portion 240, or the three sides that are substantially U-shaped) are abutting surfaces against the upper surface of the anchor member, A boot in which a standing posture is held with respect to the anchor member by supporting a plurality of continuous side portions (one set of places) on the end surface by the anchor member may be used.

  In the above embodiment, the connecting member is the webbing 28. However, since the sewing of the boot to the connecting member is not necessary, the connecting member may be another connecting member such as a wire.
