The base portion 5 is formed in an elongated and rigid plate shape having a constant width. The base portion 5 includes a flat first plate portion 6 having a fixed width on which the locking portion 2 is provided, and a second plate portion 7 having a constant width rising from the first plate portion 6 at a substantially right angle. A rib 9 extending in the longitudinal direction is preferably formed at the central portion in the width direction of the first plate portion 6 and the second plate portion 7 in order to increase the rigidity of the base portion 5. In this case, you may form so that it may become a mountain height from both edge parts toward the center of the width direction instead of the rib 9. FIG.

  In the illustrated embodiment, the attachment portion 3 includes a square head 10 having a size that can be inserted only at a predetermined angle with respect to the attachment hole formed in the square hole, and an inscribed circle of the square head 10. And a small-diameter shaft portion 11. The shape of the mounting hole in the vehicle body wall is a square hole (see FIG. 4). Correspondingly, the cross-sectional shape of the head 10 is formed in a square with a side slightly smaller than the square hole of the mounting hole (see FIG. 2 and FIG. 4). As shown in FIGS. 2 and 4, the quadrilateral cross section of the head portion 10 is the same as the square of the mounting hole when the surface of the first plate portion 6 is in a posture parallel to the vehicle body floor surface (posture in FIG. 3). Formed with a rotation angle of approximately 45 degrees. Thereby, when attaching the fastener 1 to the vehicle body wall portion, if the surface of the first plate portion 6 is inclined 45 degrees to the vehicle body floor surface and the head portion 10 of the attachment portion 3 is aligned with the attachment hole, The head 10 can be inserted into the mounting hole. After the insertion, if the surface of the first plate portion 6 is rotated in a posture parallel to the vehicle body floor surface (see FIG. 3), the head 10 cannot be removed from the mounting hole, and the fastener 1 is connected to the vehicle body wall portion. After mounting, when the surface of the first plate portion 6 of the fastener 1 is tilted to a posture rotated by 45 degrees with respect to the vehicle body floor surface, the head 10 comes out of the attachment hole, and the fastener 1 can be easily removed from the vehicle body wall portion. Can be removed.

  Between the 2nd plate part 7 and the axial part 11 of the attaching part 3, the sheet | seat part 13 contact | abutted to a vehicle body wall part is provided. As shown in FIG. 1, the seat portion 13 is formed to protrude from the surface of the second plate 9 by a certain length toward the vehicle body wall portion, and is wider than the attachment portion 3 in the vertical direction as shown in FIG. It is formed to have an area and receives a vehicle body wall. The seat portion 13 is provided with a support column 14 between the shaft portion 11 and the second plate portion 7 to maintain the rigidity of the attachment portion 3. The vehicle body wall portion can be held in the portion of the shaft portion 11 between the seat portion 13 and the head portion 10. Further, the seat portion 13 is provided with abutting ribs 15 that protrude along the head portion 10 at portions on both sides adjacent to the shaft portion 10 that are extensions of the support column 14. The abutment rib 15 abuts on the vehicle body wall portion received in the mounting portion 3, and the fastener 1 can be inclined at a certain angle with respect to the vehicle body wall portion around the abutment rib 15 (see FIGS. 9 and 10). . Further, in order to enable this inclination, the distance between the contact surface of the seat portion 13 and the lower surface of the head portion 10 is formed to be larger than the thickness of the vehicle body wall portion, and with respect to the vehicle body wall portion around the contact rib 15. Thus, the entire fastener 1 can be inclined. Thus, even if the vehicle body wall portion rises at various angles with respect to the floor surface of the vehicle body and the inclination angle differs depending on the automobile, it is possible to cope with the difference in angle. Furthermore, even when the foot of the vehicle occupant on the floor mat strongly presses the fastener 1, the mounting portion 3 can be prevented from being broken because it can be tilted from the position of FIG. 9 to the position of FIG.

  As described above, since the distance between the contact surface of the seat portion 13 and the lower surface of the head portion 10 is formed to be larger than the thickness of the vehicle body wall portion, the attachment portion 3 is not held between the vehicle body wall portion. There is a risk of looseness and rattling. As shown in FIG. 1, the shaft portion 11 is provided with one spring piece 17 that elastically contacts the vehicle body wall toward the upper side of FIG. As a result, even if the inclination angle of the vehicle body wall is different, it is held without rattling, so that it is possible to cope with the difference in inclination angle, and furthermore, the wall thickness of the vehicle body wall portion varies depending on the automobile. It can be held without any problems and can cope with the difference in thickness.

  It is preferable that a pressing rib 18 that presses and holds a carpet portion that covers a portion of the vehicle body wall portion is formed at an end portion (the upper end in FIG. 1) of the second plate portion 7. As a result, it is possible to eliminate a gap between the vehicle body wall portion and the carpet portion. Further, the second plate portion 7 has an area large enough to cover the attachment hole of the vehicle body wall portion and the cut of the carpet around the second plate portion 7 when attached to the vehicle body wall portion. As a result, the mounting hole and the cut of the carpet are hidden by the second plate portion 7 (and eventually the fastener 1), so that the design looks good.

  FIG. 3 shows a state in which the fastener 1 is attached to the vehicle body wall portion 19 and the floor mat 21 is fixed. In FIG. 3, the vehicle body wall portion 19 is in a posture of rising at an angle of 90 degrees with respect to the vehicle body floor surface 22. A panel 23 is provided on the vehicle body floor surface 22, and a carpet 25 is laid thereon. The carpet 25 extends to the vehicle body wall portion 19 and covers that portion. After the carpet 25 is laid, the floor mat 21 is arranged on the carpet 25 and fixed so as not to be displaced by the fastener 1 connected to the vehicle body wall portion 19. A mounting hole 26 for connecting the fastener 1 is formed in the vehicle body wall portion 19. The carpet 25 is cut out around the attachment hole 26 to expose the attachment hole 26. After the leading end 25 </ b> A of the cut-out carpet 25 is pushed into a position adjacent to the vehicle body wall portion 19, the fastener 1 is attached to the vehicle body wall portion 19.

  As shown in FIGS. 4A and 4B, the mounting hole 26 of the vehicle body wall portion 19 is formed as a square hole. Moreover, when the cross-sectional shape of the head 10 of the attachment part 3 of the fastener 1 is formed in a square slightly smaller than the square hole of the attachment hole, the surface of the first plate part 6 is in a posture parallel to the vehicle body floor surface 22 ( The posture of FIG. 3 is formed with a rotation angle of approximately 45 degrees with respect to the square of the mounting hole. When the fastener 1 is attached to the vehicle body wall portion 19, the surface of the first plate portion 6 is inclined to the posture rotated 45 degrees with respect to the vehicle body floor surface (FIG. 4A), and the head portion 10 of the attachment portion 3 is attached to the attachment hole. 26, the head 10 is inserted into the mounting hole as it is. By this insertion, the seat portion 13 (the contact rib 15 thereof) contacts the vehicle body wall portion 19. After the contact, if the surface of the first plate portion 6 is rotated to a posture parallel to the vehicle body floor surface 22 (see FIGS. 3 and 4B), the head 10 cannot be removed from the mounting hole, and the fastener 1 is It is connected to the vehicle body wall portion 19.

  The fastener 1 is connected to the vehicle body wall portion 19 with the vehicle body wall portion 19 between the seat portion 13 and the head portion 10, and the spring piece 17 abuts against the vehicle body wall portion 19 to bend the base portion 5 of the flexible fastener 1. The first plate portion 6 is pressed against the carpet 25 to prevent rattling after the fastener 1 is connected, and the fastener 1 is fixed to the vehicle body wall portion 19. After fixing, the floor mat 21 is placed on the carpet 25 by passing the locking holes 27 of the floor mat 21 through the locking portion 2. Thus, the fastener 1 holds the floor mat 21 so as not to be displaced on the carpet 25.

  FIG. 5 shows a state in which the second plate portion 7 covers a notch 29 around the attachment hole 26 formed in the carpet 25 extending to the vehicle body wall portion 19. The area of the second plate portion 7 has an area large enough to cover the mounting hole 26 of the vehicle body wall portion 19 and the carpet cut 29 around the mounting hole 26. Since the notch 29 is hidden, the appearance of the design is improved. At this time, as shown in FIG. 3, the pressing rib 18 presses and holds the upper end portion of the cut 29 of the carpet 25 to improve the appearance and protect the carpet terminal portion while protecting it.

  FIG. 6 shows the relationship between the portion of the carpet 25 having the notch 29 and the second plate portion 7 when the fastener 1 is attached to the vehicle body wall portion 19. When attaching the fastener 1, the second plate portion 7 is disposed in a posture rotated by 45 degrees with respect to the mounting hole 26 and the notch 29, and then rotated 45 degrees counterclockwise. A hatched portion 30 in FIG. 6 indicates a portion where the second plate portion 7 interferes with a portion of the carpet 25 on the vehicle body floor surface. The fastener 1 can be connected to the vehicle body wall portion 19 by rotating 90 degrees instead of 45 degrees. However, in this case, not only does the rotation angle increase, but the second plate portion 7 The portion that interferes with the carpet 25 portion on the floor of the vehicle body is larger than the shaded portion in FIG. 6, and the operation for connection becomes more troublesome than that of 45 degrees. After the attachment, when the surface of the first plate portion 6 of the fastener 1 is tilted to a posture rotated 45 degrees with respect to the vehicle body floor surface, the head 10 comes out of the attachment hole, and the fastener 1 is removed from the vehicle body wall portion. Easy to remove.

  FIG. 7 shows a cross section of the shaft portion 11, and is a cross-sectional view taken along the line VII-VII of FIG. The shaft portion 11 may simply have a circular cross section having a smaller diameter than the inscribed circle of the square head, but as shown in FIG. 7, the shaft portion 11 may be formed in an octagonal cross section having a smaller diameter than the inscribed circle of the square head. preferable. In that case, in FIG. 7, each corner of the quadrangle is cut off to form an octagon, and the relationship between the length a of one side of the quadrangle and the diagonal length b of the cut-off is: a <b It is preferable to be determined so that As a result, when a rotation of 45 degrees or more is attempted, a sense of resistance is transmitted to the finger or hand, which helps the operator to perform the assembly work.

  8 is the same as the attachment state of the fastener 1 of FIG. 3, but the vehicle body wall portion 19 is inclined by 7 degrees with respect to the vehicle body floor surface 22 instead of 90 degrees (that is, the vehicle body floor surface). It stands up at an angle of 83 degrees with respect to. Even in this case, the fastener 1 is connected to the vehicle body wall portion 19 without any trouble, and fixes the floor mat 21 so as not to be displaced with respect to the carpet 25. FIG. 9 shows the posture that the fastener 1 takes in a state where the vehicle body wall portion 19 is at a position of 90 degrees (A) and a case where the vehicle body wall section 19 is inclined by 7 degrees (B). FIG. 10 shows that the fastener 1 can be tilted even when the foot of the vehicle occupant on the floor mat strongly presses the fastener 1 in the direction of the arrow 31. The fastener 1 can be inclined at a certain angle with respect to the vehicle body wall portion 19 around the contact rib 15, and the distance between the contact surface of the seat portion 13 and the lower surface of the head portion 10 is formed larger than the thickness of the vehicle body wall portion. Thus, the entire fastener 1 can be inclined with respect to the vehicle body wall portion around the abutment rib 15. Thus, even if the vehicle body wall portion 19 rises at various angles with respect to the vehicle body floor surface 22 and the inclination angle differs depending on the vehicle, the vehicle occupant in the floor mat can cope with the difference in the angle. Even when the foot is strongly holding the fastener 1, it can be inclined from the position of FIG. 9 to the position of FIG. 10, and there is no possibility that the mounting portion 3 is broken.

  In the above-described embodiment, the mounting hole is formed as a square square hole. However, the shape of the mounting hole may be formed as a long hole such as a rectangle or an ellipse. When the attachment hole is formed as a long hole, the cross-sectional shape of the head portion 10 of the attachment portion 3 is preferably a rectangular shape with a slightly smaller side than the short side of the long hole. Further, as shown in FIGS. 4A and 4B, the quadrilateral shape of the head 10 is formed so as to be shifted by a rotation angle of 45 degrees with respect to the attachment hole of the elongated hole. Accordingly, the surface of the first plate portion 6 is tilted to a posture rotated by 45 degrees with respect to the vehicle body floor surface (FIG. 4A), and the head portion 10 of the attachment portion 3 is inserted into the attachment hole. If the surface of the 1 plate portion 6 is rotated in a posture parallel to the vehicle body floor surface 22 (see FIGS. 3 and 4B), the head 10 cannot be removed from the mounting hole, and the fastener 1 is attached to the vehicle body wall portion 19. Connected. Further, the shape of the mounting hole and the cross-sectional shape of the head cannot be removed from the mounting hole when the first plate portion 6 is in a posture parallel to the vehicle body floor surface 22, but a predetermined angle (for example, 45) with respect to the mounting hole. As long as it is in a relationship that allows it to escape, it can be formed into an arbitrary shape. For example, the mounting hole may be formed in a non-perfect circle (such as an ellipse or a square), and the head may be formed in a similar non-perfect circle slightly smaller than that.

  FIGS. 11 to 15 show a fastener 33 for an automobile floor mat according to the second embodiment. The fastener 33 has almost the same configuration as the fastener 1, but differs in the following points.
