Abstract

(57) [Summary] [Structure] The blinding plate is installed in such a manner that the upper part of the blinding plate is connected to the corner piece main body by a snap coupling means, and the lower part of the blinding plate has a plurality of locking protrusions. In addition, a bag-like engagement portion with an upward opening is formed on the corner piece main body corresponding to the locking protrusion, and the locking protrusion is inserted into the bag-like engagement portion to be coupled. In the corner piece for an automobile configured as described above, the front face portion of the bag-shaped engaging portion is provided with a notch portion extending from the upper end side. [Operation/Effect] Even if a convex portion (undercut) is formed to shape the hole of the bag-like engaging portion in the car-inside shape split mold, forceful removal is possible. Therefore, during molding, there is no need to form a convex portion on the outer side of the corner piece mold to form a through hole communicating with the hole of the bag-like engagement portion. Therefore, a through hole that communicates with the hole of the bag-shaped engaging portion is not formed in the corner piece, and there is no need to consider the intrusion of wind noise through the through hole when the vehicle is running at high speed.

[Problem that the idea aims to solve]

However, the hole 27 of the bag-like engaging portion 25 of the conventional configuration is directed toward the outside of the vehicle as shown in the figure. It was configured to have a communicating through hole 28.

[0006] That is, the corner piece main body 7 is formed using a mold 31 for shaping the inside of the vehicle and a mold 3 for shaping the outside of the vehicle. 3. The shape of the hole 27 of the bag-shaped engaging portion 25 is shown in FIG. As shown in FIG. At the same time, a shaped mold 31 is formed on the inside of the vehicle at the upper stage of the hole shaped protrusion 35. This is because this was done by rubbing the bag-like engagement portion with the shaped concave portion 31a.

[0007] Due to the presence of the through hole 28, air flows between the outside and inside of the vehicle, allowing the vehicle to travel at high speeds. When driving, wind noise easily penetrated into the interior of the car.

[0008] Further, after molding, burrs are likely to be formed at the opening of the bag-like engaging portion 25, and It was necessary to remove the

[0009] In order to solve the problem, in Utility Model Application Publication No. 2-60016, a bag-like engagement Actively form an obturator membrane at the opening of the tube, and sharpen the tip of the obturator membrane.

0010 However, with the above configuration, it is not possible to completely prevent wind noise from entering the inside of the vehicle. It was difficult. In particular, when replacing the door mirror, the blind plate must be removed. If the hole is broken and then reinstalled, the hole tends to become larger and wind noise may be intrusive. The effect of preventing entry is reduced.

[0011] In view of the above, this invention forms a through hole in the bag-like engagement part that conducts from the outside of the vehicle. There is no need to form a hole in the hole, and consideration should be given to the intrusion of wind noise through the through hole. The purpose of the present invention is to provide a corner piece for an automobile that does not require the use of a corner piece.

0012

[Means to solve the problem] In order to solve the above problems, the inventor of the present invention, in the course of earnestly developing the bag-like engagement part, Focusing on the fact that it is made of elastomer, we created the following configuration that allows for easy release during mold release. I came up with this idea and completed this idea.
