Description of the Related Art Conventionally, in order to mount a front window glass of a vehicle to a vehicle body, for example, a plastic molding having a sectional shape as shown in FIG. 9 is provided on a window glass mounting portion of a vehicle body panel. This mall 1
Is also disclosed in Japanese Utility Model Publication No. 59-51611,
It has an upper side 2a, a bridging piece 2b, and a lower side 2c and has a substantially U-shaped cross-sectional shape fitted and mounted along the periphery of the window glass so as to form an opening holding the periphery of the window glass G. The base 2 is formed to extend from the position of the upper side 2a and the lower side 2c of the base 2 in the direction opposite to the upper side 2a and the lower side 2c, ie, to the side opposite to the window glass G side. An upper lip 3 and a lower lip 4 are provided. The molding 1 configured as described above is fitted to the periphery of the window glass G as shown in FIG. 10, and further, a primer M is applied to the lower surface of the molding 1, and then the periphery of the window glass G and the opening of the vehicle body panel P. The edge P1 is bonded to the vehicle body panel P with the adhesive E. The adhesive E also bonds the lower surface of the base 2 of the molding 1 to the body panel P. Then, the lower surface of the tip of the upper lip portion 3 of the molding 1 has a surface portion P2 which is higher than the opening edge P1 of the vehicle body panel P toward the outside of the vehicle body (this portion is A
(Which is part of a pillar or a roof panel), and the tip of the lower lip portion 4 is connected to the opening edge P1 and the surface P2 of the body panel P by an opening edge P1.
And it is comprised so that it may elastically contact the side surface of the wall part P3 substantially perpendicular | vertical with respect to the surface part P2. D is the adhesive E
It is a dam member for preventing protrusion. The lower lip 4 of the molding 1 is inclined at an angle θ with respect to the surface of the window glass G as shown in FIG. In this state, the abutment is in contact with the side surface of the wall portion P3 of the vehicle body panel P with the contact force F. Therefore, a counterclockwise rotational force about the point A acts on the molding 1. When θ is not so large as shown in FIG. 10, the component Fx substantially perpendicular to the wall P3 is large and the component Fy upward is small, so that the lower lip portion 4 is
3 has sufficient system adhesion. However, when the edge of the window glass G approaches the side surface of the wall portion P3 of the vehicle body panel P due to a mounting error between the window glass G and the vehicle body panel P as shown in FIG. Along with this, the upward component force Fy of the contact force F of the lower lip portion 4 in the figure increases, and the lateral component force Fx in the figure decreases, so that the point A acts as a fulcrum and acts on the molding 1. The rotating force to be applied also increases. Therefore, the adhesive E
If vibration or the like is applied to the window glass G before the glass is hardened, the molding 1 rises upward due to the vibration, and the appearance is impaired, or the mold 1 is easily detached from the vehicle body panel P. Accordingly, the present invention provides a sufficient system force on the vehicle body panel even when the distance between the edge of the window glass and the side surface of the vehicle body panel is reduced due to an error in mounting the window glass to the vehicle body panel. It is an object of the present invention to provide a molding structure of a vehicle having the following. According to the present invention, there is provided a molding structure for a vehicle, comprising: an opening edge to which a periphery of a window glass is adhered by an adhesive; and a surface portion higher than the opening edge to the outside of the vehicle body. A molding provided on a window glass attachment portion of a vehicle body panel having a wall portion substantially perpendicular to the opening edge portion and the surface portion for connecting the opening edge portion and the surface portion. The molding has a base having a substantially U-shaped cross-sectional shape fitted along the periphery of the window glass, and extends from the upper end of the base to the side opposite to the window glass side so that the lower surface of the tip is a vehicle body. An upper lip portion elastically contacting the surface portion of the panel, and a lower lip portion extending from the lower end of the base portion to the opposite side to the window glass side and having a tip elastically contacting the side surface of the wall portion of the vehicle body panel. Be prepared In the molding structure of the vehicle, the lower lip has a V-shape bent upward, and between the lower end of the base and the base of the lower lip, the base glass and the window glass side A notch cut from the opposite surface is formed to have a cross-sectional shape interposed. According to the present invention, the lower lip has a V-shape bent upward, and the base of the lower lip is opposite to the window glass side of the base. Since it has a cross-sectional shape in which a notch cut from the surface intervenes, the ability to absorb a mounting error of the window glass to the vehicle body panel is increased. That is, even if the distance between the edge of the window glass and the side surface of the wall of the vehicle body panel where the tip of the lower lip portion elastically contacts is reduced due to the above mounting error, the lower lip portion is bent from the middle, and Not only does the frictional force of the tip of the lower lip against the side of the wall of the panel increase, but also in this case, the contact angle θ with respect to the side of the wall of the body panel can be kept small. The component force Fx of the contact force F with respect to the side surface of the portion becomes large, and a sufficient engaging force with respect to the vehicle body panel can be maintained, and the point of action of the lower lip portion can be moved away from the fulcrum of the molding, whereby The moment in the direction of engagement of the mall with the vehicle body panel is increased, so that the molding can be prevented from being lifted. Furthermore, the lower lip has a V-shaped cross section as described above, and in addition to the above, a notch is formed at the root of the lower lip.
There is an advantage that compliance of the lower lip portion is increased, insertion of the molding into the vehicle body panel is facilitated, and assemblability is improved. Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is a cross-sectional view corresponding to FIG. 9 of a vehicle molding structure according to the present invention. Mall 11 shown in FIG.
In this case, the structure of the conventional molding 1 shown in FIG. 9 is the same as that of the conventional molding 1 shown in FIG. 9 except that the structure of the lower lip 14 is different and the notch 15 is formed at the base of the lower lip 14. Have. Therefore, the same components as those in FIG. 9 are denoted by the same reference numerals, and the duplicate description will be omitted.
The lower lip portion 14 of the molding 11 shown in FIG. 4 includes a first portion 14a on the base side extending obliquely downward from the lower end of the base 2 and a second portion 14b on the tip side bent upward from a predetermined intermediate position. It is formed to have a shallow V-shaped cross section. In addition, since the notch 15 is formed at the base of the first portion 14a, the length of the lower lip portion 14 is increased, and the lower lip portion 14 is easily bent upward. FIGS. 2 and 3 show the mounting state of the molding 11 in correspondence with FIGS. 10 and 11, respectively. As is apparent from FIG.
The point at which the tip of the second portion 14b of 14 contacts the wall P3 of the vehicle body panel P) is located below the point of action on the lower lip 4 of the conventional molding 1 shown in FIG.
Accordingly, the point of action can be moved away from the fulcrum of the molding 11 (point corresponding to the point A in FIG. 10), whereby the moment in the engaging direction of the molding 11 with respect to the vehicle body panel P increases, and the molding 11 rises. Can be prevented.
As is apparent from FIG. 3 in particular, when the edge of the window glass G approaches the side surface of the wall portion P3 of the vehicle body panel P, the second portion 14b on the tip side of the lower lip portion 14 adheres to the side surface of the wall portion P3. And the contact angle θ of the first portion 14a on the base side to the side surface of the wall portion P3 is kept at a small value, so that the component Fx of the contact force F to the wall portion P3 increases, It is clear that the system applied force to the wall portion P3 is larger than that of the conventional molding 1. Since the notch 15 is formed at the base of the lower lip portion 14, even when the edge of the window glass G and the side surface of the wall portion P3 of the vehicle body panel P are further closer than in FIG. The first portion 14a of the portion 14 can be bent further upward to absorb the mounting error, and the moment in the direction of engagement of the molding with the vehicle body panel can be increased to prevent the molding from floating. In this embodiment, prior to bonding the window glass G to the vehicle body panel P with the adhesive E, the primer M is not only placed on the lower surface of the molding 11 but also on the molding 11.
Is applied continuously to the upper surface of the lower piece 2c in contact with the window glass G of the base 2 and the side surface of the bridging piece 2b.
The reason is as follows. That is, when the window glass G is bonded to the vehicle body panel P, the adhesive E

b, but hardens in about 1 hour (adhesive E
Much shorter than the cure time of the other parts of
Therefore, if primer M is applied to this part,
This is because the molding 11 can be fixed to the window glass G at an early stage. FIG. 4 is an exploded perspective view of the case where the window glass G is mounted on the vehicle body panel P using the molding 11 according to the present invention. The lower molding 16 is attached to the lower edge of the window glass G. As shown in FIG. 5, a part of the lower lip portion 14 is cut out in a portion indicated by reference numeral V at a center of a portion fitted to the upper edge of the window glass G of the molding 11, and an attachment reference is provided there. Mark portion 17 is provided. Then, the molding 11 is attached to the window glass G in such a positional relation that the mark portion 17 coincides with the mark 18 provided at the center of the upper edge of the window glass G.
Conventionally, this mark was applied to the mall by paint or the like, so that there was a drawback that the mark became unclear or disappeared. However, the above drawback can be avoided by providing the mark portion 17 as shown in FIG. In addition, at the corners of the molding 11 indicated by the reference numeral VI in FIG. 4, appropriate slits 19 and cuts 20 as shown in FIG. ing. Further, FIG.
Also at the end of the molding 11 indicated by the symbol VII,
A plurality of cuts 21 as shown in FIG. 7 are provided in the lower lip portion 14 to enhance the compliance of this portion and facilitate insertion into the vehicle body panel P. According to the present invention, since the lower lip portion 14 of the molding 11 has a shallow V-shaped cross-sectional shape, the problem that the lower lip portion 14 comes off is almost eliminated.
When using for mounting the windshield, etc.
In some cases, it is necessary to further improve the reliability. In that case, a protector having a sectional shape as shown in FIG.
22 may be used. That is, the protector 22 is disposed along the vehicle body panel P so as to extend from the wall portion P3 of the vehicle body panel P to the lower surface of the lower rib portion 14 of the molding 11, and has a plurality of locking members. Hook 23 is mall 11
It protrudes toward the side and with a vertical interval. The molding 11 is mounted such that the tip of the lower lip portion 14 is locked below the hook 23. Thereby, the mounting strength of the molding is sufficiently ensured, and the reliability can be improved.
