SUMMARY OF THE INVENTION Therefore, according to the present invention, a retainer having a substantially U-shaped cross section and fixed to the opening edge of a vehicle body with a screw and an opening of the retainer are formed so as to cover the retainer. A hollow seal part for sealing the edge of the windshield, and the hollow seal part is formed integrally with the retainer, and only the end of the hollow seal part on the vehicle interior side side is connected to the core metal. In a weather strip for an automobile configured such that the other end portion is engaged and held, a locking piece for locking the tip end portion of the hollow seal portion is provided on the bottom portion of the retainer having a substantially U-shape, It is characterized in that the hollow seal portion is configured to be temporarily fixed while being deformed inward.

[0006]

In the state where the hollow seal portion is pushed into the retainer, the tip of the hollow seal portion is held by the locking piece, and a predetermined temporary fixing state is established. In this state, since the opening of the retainer is opened, the retainer can be screwed as it is. Then, if the hollow seal portion is disengaged from the locking piece after the retainer is screwed, the hollow seal portion has a desired posture to cover the opening portion of the retainer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a weather strip 1 according to the present invention attached to a roof side rail 2 on the side of an automobile.

The weather strip 1 is formed by integrally extruding a metallic retainer 3 having a substantially U-shaped cross section and a rubber portion such as a hollow seal portion 4, and the retainer 3 is a roof side. A mounting base portion 3a in contact with the panel surface of the rail 2, a leg portion 3b on the vehicle interior side formed by bending a side edge of the attachment base portion 3a on the vehicle interior side, and a side edge on the outside of the vehicle compartment are formed by bending. It has a leg portion 3c outside the vehicle compartment. A glass guide 5 made of hard rubber is provided at the tip of the leg portion 3c on the outside of the vehicle compartment, and the leg portion 3c is provided.
On the inner surface of the sub-seal 6
Are formed. The hollow sub-seal portion 6 is made of sponge rubber. Also, the mounting base 3a
Have through holes 7 at appropriate intervals and are fixed to the roof side rail 2 by screws 8 using the through holes 7.

The hollow seal portion 4 has a loosely curved base portion 9 made of solid rubber and a sponge rubber seal portion 10 which bulges outside thereof, and the end portion 9a of the base portion 9 on the vehicle interior side. Is bent upward and is fixed to the leg portion 3b of the retainer 3 on the vehicle interior side. That is, the hollow seal portion 4 is connected to the leg portion 3b so as to be bent and deformable inward of the retainer 3. A protruding portion 11 bent in a loose hook shape is extendedly formed at the tip of the base portion 9 and is in a state of being substantially in contact with the surface of the mounting base portion 3a of the retainer 3. Further, the vehicle exterior side portion of the seal portion 10 is engaged with the glass guide 5 from the inside, whereby the outward projection is prevented and the hollow sub seal portion 6 is in a substantially contact state. That is,
In the mounted state as shown in FIG. 1, the hollow seal portion 4 is shaped so as to cover the opening of the retainer 3, and the edge of the window glass 12 of the sashless door can be sealed by the hollow seal portion 4. it can. When the hollow seal portion 4 is deformed upward in the figure, it comes into contact with the hollow sub-seal portion 6 and supports the hollow seal portion 4 from behind, so that a sufficiently high seal reaction force can be obtained.

On the other hand, a locking piece 13 made of solid rubber is projected from the inner surface of the mounting base 3a of the retainer 3, more specifically, closer to the passenger compartment than the through hole 7. This locking piece 1
Reference numeral 3 indicates a hook-shaped curve that is loosely curved toward the vehicle interior side, and is provided at a position where it can engage with the protrusion 11 of the hollow seal portion 4. The locking piece 13 is also extrusion-molded at the same time as the hollow seal portion 4 and the like.

The molding 14 provided on the outer side surface of the retainer 3 is welded after the weather strip 1 is formed. Reference numeral 15 is a decorative lip that covers the end of the roof liner 16.

As shown in FIG. 2, the weather strip 1 constructed as described above is carried into the vehicle body outfitting line after the hollow seal portion 4 has been pushed into the retainer 3 to be temporarily fixed. That is, by pushing the hollow seal portion 4 inward in advance, the protrusion portion 1 at the tip of the hollow seal portion 4 is pushed.
1 engages with the locking piece 13, and the hollow seal portion 4 retains the retainer 3
It will be a shape that falls inside the. At this time, a string 16 having sufficient strength is previously arranged between the hollow seal portion 4 and the leg portion 3b. In this temporarily fixed state, the opening of the retainer 3 is opened, so that the retainer 3 can be fixed by inserting the screw 8 through the gap as shown in the drawing. That is, it is not necessary to hold the hollow seal portion 4 with fingers, and the screwing operation can be performed very easily.

After the screwing work is completed, the string 16 is pulled out toward the opening portion side of the retainer 3 through the space between the projection 11 and the locking piece 13, and the projection 11 is sequentially locked.
Since the hollow seal portion 4 tries to return to the opening side of the retainer 3 due to its own elasticity, it is possible to finally obtain the mounting state shown in FIG.

[0015]

As is apparent from the above description, according to the weather strip for an automobile of the present invention, the hollow seal portion is integrally formed with the retainer, and when the retainer is screwed, the hollow seal portion is applied to the fingers. There is no need to hold it down, and the screwing work can be done very easily. Therefore, it is possible to improve the work efficiency in the fitting line of the vehicle body.
