The webbing 1 extends from the rear end portion of the lower surface of the seat cushion S2 that is flipped up and faces the vehicle interior, and a male buckle 2 having substantially the same structure as that of each of the above embodiments is attached to the front end thereof. On the other hand, in the pillar portion P located at the rear opening edge of the vehicle, a holder 7 that houses a female buckle 71 that can be engaged with the male buckle 2 is provided at an intermediate position in the vertical direction that can be reached from the outside of the vehicle. Is provided.

  A sectional view of the holder 7 is shown in FIG. 10, and an exploded perspective view thereof is shown in FIG. The holder 7 includes a substantially rectangular container body 72 that opens to the inside of the vehicle (downward in FIG. 10). The container body 72 is fixed to the inner panel 41 of the pillar portion P by a bolt 73 that passes through the bottom wall 721. Has been. The container body 72 is installed in an opening 421 provided in a garnish 42 as an interior member, and a substantially U-shaped insertion recess is provided on the outer edge of the opening 722 of the container body 72 at an opposite position across the opening 722. Are formed, and an opening edge 422 of a garnish 42 that is recessed inwardly in a stepped manner is inserted and locked in these locking portions 723 and 724.

  A bracket 74 is provided, and is formed into a substantially U shape in which standing wall portions 742 are formed on both sides of the substrate portion 741. The board portion 741 of the bracket 74 is located between the bottom wall 721 of the container body 72 and the inner panel 41, and is fixed to the inner panel 41 together with the container body 72 by bolts 73. The left and right standing wall portions 742 of the bracket 74 are disposed along the outer surface of the side wall of the container body 72, and mounting holes 743 (FIG. 11) provided at the tip of the standing wall portion are provided on the opposite side walls of the container body 72. It corresponds to the mounting hole 727. A shaft 76 as a shaft body is installed so as to pass through the mounting holes 743 and 727 and cross the container body 72, and the base end 711 of the female buckle 71 is rotatably attached to the shaft 76. ing.

  In the main body 711 of the female buckle 71, the male buckle 2 is received between the pair of side walls 712 and 713 located in the vehicle inside / outside direction (vertical direction in FIG. 10), and in the distal direction for locking it. An open recess 714 is formed. A locking projection 715 (FIG. 10) is formed at the tip of the outer side wall 713 of the main body 71, and the locking projection 715 enters into a locking hole 725 formed in the side wall of the container body 72, so that the female mold The buckle 72 is positioned at a retracted position in the container body 72. A locking protrusion 716 that rises in a triangular shape is formed on the base end surface of the female buckle body 711 at the left and right positions.

  A lid 75 is attached to the inner side wall 712 of the female buckle body 711 along the same. The front end edge of the lid 75 is folded back into two U-shapes to form a locking piece 751 (FIG. 11), while the inner surface of the base end 754 of the lid 75 has a locking hole 753 at the left and right positions. The standing wall 752 provided with is formed. The lid 75 is fitted with the locking hole 753 of the base end upright wall 752 in the locking protrusion 716 of the female buckle body 711 in a state where the locking piece 751 at the leading edge is locked to the thin leading edge of the inner wall 712. By doing so, it is fixed to the female buckle body 711. The lid 75 is made of the same material as the garnish 42, and the surface of the lid 75 is substantially flush with the surface of the garnish 42 as shown in FIG. 10 with the female buckle 71 retracted into the container 72. Thus, the design of the garnish 42 is not impaired. In this state, the base end 754 of the lid 75 is located on the opposite side of the general portion of the lid 75 across the shaft 76. Engaging protrusions 717 are formed on both side surfaces (one shown in FIG. 11) at the base end of the female buckle main body 711 through which the shaft 76 is inserted, and around the shaft penetrating portion on the side wall of the container body 72. An engagement hole 726 into which the engagement protrusion 717 can be fitted is formed in one place.

  When the holding device is used, when the outer surface of the base end 754 of the lid body 75 is pushed into the container body 72 as indicated by the arrow in FIG. 10, the engagement formed on the distal end of the outer wall 713 of the female buckle 71 is engaged. The stop projection 715 is withdrawn from the locking hole 725 on the side wall of the container body 72, and the main body portion 711 of the female buckle 71 rotates inward of the vehicle around the shaft 76, as shown by the chain line in FIG. The opening of the recess 714 becomes the advance position toward the inside of the vehicle. At the advanced position, the engagement protrusion 717 is fitted into the engagement hole 726, and the main body 711 is maintained in the advanced position.
