(Installation instructions)
Next, attachment of the fastener 12 will be described.
As shown in FIG. 6, the back surface 1402 of the substrate portion 14 of the fastener 12 is attached to the window glass 4 with a double-sided adhesive tape or the like. In this case, the adhesive S is applied over the entire circumference of the window glass 4.
Then, the window glass 4 faces the vehicle body panel 8, and the hook 16 and the guide piece 22 of the fastener 12 are inserted into the holes 8002 of the vehicle body panel 8.
When the hook 16 is inserted into the hole 8002, as shown in FIG. 7, the locking portion 1602 gets over the edge of the hole 8002, and each guide piece 22 comes into contact with the edge of the hole 8002. Vertical and horizontal positioning is performed.
The elastic piece 18 elastically contacts the vehicle body panel 8 and urges the window glass 4 in a direction away from the vehicle body panel 8, and the locking portion 1602 is locked to 8 positions on the vehicle body panel around the hole 8002.
Accordingly, the window glass 4 is locked and held in a state in which the window glass 4 is positioned away from the vehicle body panel 8, and the window glass 4 is attached to the vehicle body panel 8 by the curing of the adhesive S.
In FIG. 8, reference numeral 24 denotes a windshield molding that seals the gap between the window glass 4 and the vehicle body panel 8.

According to the present embodiment, the elastic piece 18 of the fastener 12 has the base portion 1802 connected to the substrate portion 14. When the substrate portion 14 is viewed from the thickness direction of the substrate portion 14, the base portion 1802 is excluded. An opening 20 sized to accommodate the remaining elastic piece 18 is provided in the substrate portion 14 for each elastic piece 28. The elastic piece 18 is cantilevered and the tip of the elastic piece 18 in the protruding direction is the substrate portion. 14 is disconnected.
Therefore, a mold that slides in the thickness direction of the substrate section 14 is sufficient as a mold for molding the fastener 12, and a mold that slides in a direction orthogonal to the thickness direction of the substrate section 14 is not necessary.
Therefore, the mold can be simplified, and the mold can be easily designed and manufactured, which is advantageous in reducing the cost.
In addition, for example, when the size of the elastic piece is changed according to the vehicle type, such as when the distance between the window glass 4 and the vehicle body panel 8 is to be changed, the length of the elastic piece 18 needs to be adjusted. Since the structure of the mold is simplified, it is not necessary to re-create the mold from the beginning as in the prior art, and adjustment of the mold can be facilitated, which is advantageous in reducing the manufacturing cost of the mold.
In addition, since the elastic piece 18 is cantilevered and the tip of the elastic piece 18 in the protruding direction is separated from the substrate portion 14, by securing the length of the elastic piece 18, the shape and size of the vehicle body panel 8 can be reduced. This is advantageous in absorbing variations.
Particularly, since the elastic piece 18 is a cantilever type as compared with the conventional case where an annular structure is used as the elastic piece, the elasticity of the elastic piece 18 does not become too strong, and the shape of the vehicle body panel 8 is reduced. It is even more advantageous in absorbing variations in dimensions.
Further, since a gap with a certain size is formed in the thickness direction of the window glass 4 between the vehicle body panel 8 and the space between the window glass 4 and other parts is too large, This is advantageous in reliably preventing the parts from coming close to each other and interfering with each other.
Further, since the adhesive S is cured in a state in which a gap having a certain dimension is formed in the thickness direction of the window glass 4 between the window glass 4 and the vehicle body panel 8, the adhesion interposed between the window glass 4 and the vehicle body panel 8 is performed. Since the thickness of the agent S can be kept constant, it is advantageous in securing the sealing performance by the adhesive S, and the adhesive S partially breaks between the window glass S and the vehicle body panel 8 to cause a seal failure. This is advantageous in reliably preventing this.
