In FIG. 1, a rear weather strip 2 is attached to the periphery of a vehicle body opening to which a rear door 1 of a hard top vehicle is attached, and a front weather strip 4 is attached to a vehicle body opening periphery to which a front door 3 is attached. The basic configuration such as the points described above is the same as the above-mentioned conventional one. The rear weather strip 2 constitutes one weather strip, and the front weather strip 4 constitutes the other weather strip.

Here, the front end 8 of the rear weather strip 2 is formed with a thin fitting hole 18, and a grommet 11 as shown in FIG. 2 is attached therethrough. Note that the grommet 11 is not hatched for convenience of illustration.

The grommet 11 is made of resin and has a rectangular head 11a and a truncated cone-shaped tip 11b.
The head 11a is fitted to the rear weather strip 2, and the tip 11b is inserted into the mounting hole 10 formed in the outer panel 7 of the center pillar 5.

Here, the head portion 11a of the grommet 11 is
Is thicker than the thickness of the end portion 8 of the rear weather strip 2.

On the other hand, the terminal 9 at the rear portion of the front weather strip 4 is superposed on the terminal 8 at the front portion of the rear weather strip 2, and the thickness of the entire superposed portion is approximately the same as the thickness of the general portion of the rear weather strip 2. They are formed so as to be equal to each other, and a core metal 13 is installed in the middle part.

A concave portion 19 is formed on the side where the core metal 13 is arranged and which faces the grommet 11 (inside the vehicle compartment), and the core metal 13 is exposed to expose the head 1 of the grommet 11.
It is designed to receive 1a.

The core metal 13 is also exposed outside the vehicle compartment, and a recess 20 for accommodating a head portion 15a of a screw 15 described later is formed in this portion, and a screw hole 21 is provided.

Next, the operation will be described.

First, the terminal 8 of the rear weather strip 2
The head portion 11a of the grommet 11 is inserted into the fitting hole 18 of.

The tip 11b of the grommet 11 is attached to the outer panel 7 of the center pillar 5 through a mounting hole 1
Insert at 0. This allows the rear weather strip 2
Is accurately and easily positioned with respect to the center pillar 5.

Next, the end 9 of the front weather strip 4 is aligned with the recessed portion 19 of the end 9 on the vehicle interior side of the head 11a of the grommet 11, and the core metal 13 is brought into contact with the grommet 11 to form the rear weather strip. 2 terminal 8 is polymerized.

As a result, the end 9 of the front weather strip 4 can also be accurately and easily positioned on the grommet 11, that is, the end 8 of the rear weather strip 2.

Then, a screw 15 is inserted into the screw hole 21 of the front weather strip 4 and fastened to the grommet 11, and the terminals 9 and 8 of the front weather strip 4 and the rear weather strip 2 are fastened to the center pillar 5.

Therefore, since the front weather strip 4 tightened by the screws 15 has a structure in which the core metal 13 is pressed against the grommet 11, the front weather strip 4 and the rear weather strip 2
The elastic body portion of is not deformed and can be attached at the position as set.

The shape of the grommet 11 is, for example, as shown in FIG. 3, a head portion 11a having a wall portion 11c formed on the side edge thereof toward the inside of the vehicle, and as shown in FIG. 4, the head portion 11a. It is possible to employ the one in which another wall portion 11d extending from the side edge wall portion 11c to the tip 11b is provided.

Further, even in the case of the structure in which the front weather strip 4 and the rear weather strip 2 are integrally molded as shown in FIG. 5, the grommet 11 can be used for easy and accurate mounting.

Then, as shown in FIG. 6, the grommet 1
A peripheral groove 11e is formed on the outer periphery of the head portion 11a of No. 1 and when the head portion 11a is inserted into the fitting hole 18 of the terminal 8 of the rear weather strip 2, the inner periphery of the fitting hole 18 is fitted into the peripheral groove 11e. It is also possible to adopt a structure in which the positioning and the attachment of the both are performed more reliably by combining them.

The present invention is not limited to the above-described embodiments, but the end of the rear weather strip may be superposed on the end of the front weather strip.

[0029]

As described above, according to the present invention, one weatherstrip can be positioned and attached via the grommet, and the core metal of the other weatherstrip can be brought into contact with this grommet for positioning. There is an effect that the number of assembling steps is small and the mounting can be performed accurately.

Further, when the other weather strip is tightened, since the core metal of the other weather strip is in contact with the grommet, the other weather strip or the like is not deformed by the tightening force. There is an effect that the weather strip can be attached at an accurate position.
