[0002]

2. Description of the Related Art A conventional roof molding for a vehicle is formed, for example, in a U-shaped concave groove 910 formed at a joint portion between a roof panel 90 and a side structure 80 as shown in FIG. It is designed to be mounted via a plurality of clips 50 provided along the longitudinal direction. More specifically, first, a plurality of clips 50 each having a return portion 550 are provided along the longitudinal direction of the concave groove 910 at the bottom of the concave groove 910, and on the other hand, a roof molding for a vehicle is provided. 10
Is constituted by a roof-like lid 110 formed so as to cover the whole of the concave groove 910 and a hook 120 formed to extend downward from the lid 110. The vehicle roof molding 10 is mounted on the roof panel 90 at the concave groove 910 by engaging the hook portion 120 of the roof molding 10 with the return portion 550 of the clip 50. Things. As described above, in the related art, when mounting the roof molding 10 for a vehicle, a plurality of clips 50 must be installed in the concave grooves 910 on the roof.
However, there is a problem that the installation work and the like must be complicated.

[0003]

In order to solve such a problem relating to the installation of the clip, a so-called clipless type in which the above-mentioned clip is eliminated has been developed. For example, Japanese Utility Model Publication No. 7-8313. It is already publicly known in a gazette or the like. By the way, in this vehicle, an engaging member such as an engaging hook or the like is provided at both ends in the longitudinal direction of the roof molding for a vehicle, and the engaging member is engaged with a member on the vehicle body side. For example, as shown in FIG. 6, a lip 150 that is elastically deformed is provided so as to be engaged with the vertical wall 990 of the concave groove 910 by frictional force. Therefore, for the sake of adopting such a configuration, the vertical wall 990 has a tapered shape. That is, the width (D) of the upper opening portion is smaller than the width (D ′) of the bottom portion of the concave groove 910. With such a configuration, in recent vehicles, a roof rail serving as a base for mounting a roof carrier is mounted on the roof panel. In mounting such a roof rail, there is a demand to increase a surface area of a base portion serving as a mounting base of the roof rail in order to obtain the mounting stability. In order to mount the roof rail base having such a large surface area in the concave groove 910, it is necessary to ensure a sufficient width (D) of the opening. That is, it is desired to make D ≒ D '. However, the groove 9 in such a state of D ≒ D ′
If the tenth is formed, there is a possibility that the vehicle roof molding installed (mounted) jumps out of the concave groove 910 in a part of its longitudinal direction and escapes. In order to solve such a problem, even when the opening groove width is sufficiently set, the vehicle roof molding ensures that the vehicle roof molding is securely engaged in the concave groove. The purpose (problem) of the present invention is to provide molding.
It is.

The lip is easily inverted even if a force is applied to pull the roof molding out of the groove because it is also provided so as to protrude from the upper part of the base part in a branch shape. No, and therefore, does not escape from the groove. That is, one of the lips, which is provided so as to protrude toward the side wall from the base portion of the base portion, is installed at the deepest portion of the concave groove, so that the tip portion does not reverse, Therefore, it does not come out of the concave groove. Also, the other lip, which is provided so as to project from the upper side of the base portion, is supported from below by a rigid base portion from the base portion to the middle portion, and therefore, the lip is provided. The tip comes into wedge-like engagement (engagement) with the side wall of the groove. As a result, the roof molding does not easily come out of the groove (see FIG. 2). As described above, in the device of the present invention, by installing the left and right lips in a stepped manner in the vertical direction, the mounting in the concave groove is easily performed. As a result, the roof molding is securely held in the concave groove.

Next, the invention according to claim 3 will be described. This is also basically the same as the first and second aspects. A feature of the present invention is that in the roof molding for vehicles according to claim 1 or 2, both ends thereof and a base portion made of a hard plastic material have a predetermined length in a longitudinal direction thereof. In addition to the notch, a clip part made of a hard plastic material and engaging with a stud provided in a concave groove of the roof is integrated with the notched base part by injection molding means. It was decided to adopt a configuration that was provided in an appropriate manner.

By employing such a configuration, the present invention has the following effects.
