る。FIG. 7 is a cross-sectional view showing a state where the weather strip 5 is mounted along the door frame 11. The weather strip 5 is made of a material having rubber-like elasticity, such as EPDM rubber or olefin-based heat. It is made of a foam of a plastic elastomer (TPO) and includes a mounting base 51, a hollow main seal portion 52, and a lip-shaped sub seal portion 53. The sub-seal portion 53 extends from the mounting base portion 51 at a position outside the vehicle with respect to the main seal portion 52, and the distal end side is bent in a substantially rectangular shape in a cross section toward the outside of the vehicle.

And door frame 11 along rear pillar 2B (FIG. 6)
In the vicinity of the rear vertical frame part, an unusual noise may be generated. This abnormal noise will be described with reference to the rear door 1. When the door opening operation is started, as shown in FIG. 8, the tip of the sub-seal portion 53 which contacts the outer peripheral end surface 21 of the door opening of the rear pillar 2B is caught, and However, the sub-seal portion 53 is bent without detaching from the outer peripheral end surface 21, and when the door 1 is further opened, the bent sub-seal portion 53 is rapidly separated from the end surface 21 by a repulsive force and restored to its original shape. The above noise is generated at the time of restoration.

ず、材料や工数がコスト高となる問題がある。Therefore, as a measure for preventing the sub-seal portion 53 from being caught, it has been proposed to provide a member for improving the slidability of the tip of the sub-seal portion 53 on the outer peripheral end surface 21 of the door opening (Japanese Patent Laid-Open No. 11-111). 334384). However, in this measure, a separate member must be provided, and there is a problem that materials and man-hours increase in cost.

ル部７３にも上記と同様の問題がある。FIG. 9 shows a typical example, in which a weather strip 6 integrally provided with a trim portion 60 and a hollow seal portion 61 is attached to a flange 23 at a door opening edge of a vehicle body. On the other hand, a weather strip 7 having a mounting base 72 and a lip-shaped seal 73 having a rectangular cross section is mounted on a retainer 13 formed on the outer periphery of the door frame 11.
When the door is closed, the sealing portion 61 of the weather strip 6 is pressed against the inner surface of the door frame 11, and the sealing portion 73 of the weather strip 7 is pressed against the outer peripheral end surface 21 of the door opening.
The lip-shaped sealing portion 73 of the weather strip 7 having such a structure has the same problem as described above.

口外周端面から離脱せしめるようにしたのである。According to the present invention, when the door is opened in a state where the sub-seal portion or the seal portion is hooked on the outer peripheral end surface of the door opening edge of the vehicle body, the deformation which occurs in each of the seal portions mainly occurs at the base portion thereof. It was made by paying attention to. That is, as shown in FIG. 8, when the door is opened in a state where the tip of the sub-seal portion 53 is hooked, the V-shaped tip of the sub-seal portion 53 does not reversely bend in the opposite direction. The root portion 531 of the portion 53 is bent, and the sub-seal portion 53 assumes a posture in which the sub-seal portion 53 falls down toward the vehicle interior. According to the present invention, the lip-shaped sub-seal portion or the base portion of the seal portion is formed of a hard material to give rigidity, and when the door is opened, these seal portions can be detached from the outer peripheral end surface of the door opening without falling down when the door is opened. is there.

A hollow main seal portion 52 swelling diagonally upward from the mounting base portion 51 toward the vehicle interior, and extending upward from the mounting base portion 51 at a position in contact with the base end of the main seal portion 52 on the vehicle outside. A lip-shaped sub-seal portion 53 is provided. The sub-seal portion 53 is bent in a substantially U-shaped cross section toward the outside of the vehicle at an intermediate position.

When closed, as shown by the broken lines in FIGS. 1 (A) and 1 (B),
The sub-seal portion 53 of the weather strip 5A is in a more bent posture than the original shape, and the front end thereof is pressed against the opening surface of the outer peripheral end surface 21 of the door opening edge. In the door opening operation, frictional resistance is inevitably generated between the end surface 21 and the tip of the sub seal portion 53. The friction resistance is particularly large when sand or dust adheres to the end face 21.

元運動の幅は小さいから異音を発するには至らない。The frictional resistance causes the tip of the sub-seal portion 53 to be caught, and the mounting base portion 51 tries to move outward integrally with the door 1 so that the root portion 531 of the sub-seal portion 53 moves.
Bending force in the vehicle direction is applied to it, the base portion 531 is not bent almost from being formed in the rigid non-foamed material S 1. For this reason, the tip of the sub-seal part 53 is pulled out from the outer peripheral end face 21 of the door opening with the movement of the door 1 without the sub-seal part 53 falling down inside the vehicle. Immediately after being pulled out, the sub-seal portion 53 is restored to its original shape, but does not generate abnormal noise because the width of the restoring motion is small.

By forming the base portion of such a weather strip with a material having a foaming ratio of about 20% or less and having a higher rigidity than other portions, substantially the same operation and effect as in the previous embodiment can be obtained. A weather strip having a different expansion ratio between the root portion of the sub-seal portion and other portions can also be obtained by integral extrusion.

で、異音の発生を防止することができる。There is a type of door frame of an automobile door in which a corner portion at an upper rear end has a right angle or a bent angle close thereto. In such a door frame, an extruded weather strip along the upper horizontal frame and a separately formed extruded weather strip along the rear vertical frame are connected at a molding corner. In such a door, generation of abnormal noise can be prevented by forming the base portion of the sub-seal portion of the weather strip only along the rear vertical frame portion with a hard material.

ら水がリテーナ内に侵入するのを防止する効果もある。According to the present invention, the unpleasant noise generated due to the deformation of the lip-shaped seal portion of the weather strip at the time of opening the door of the vehicle is generated along at least the rear vertical frame portion of the door frame. This can be prevented by forming the base of the sealing portion of the weather strip with a harder material than other portions. Since a weatherstrip partially made of a hard material is obtained by integral extrusion, it does not lower the productivity of the weatherstrip or increase the cost. In addition, by making the base of the seal part hard, it prevents the seal part from falling down inside the vehicle due to water pressure during high-pressure washing, and water enters the retainer from between the seal part and the outer peripheral edge of the door frame. It also has the effect of preventing the user from doing so.
