2. Description of the Related Art A mounting object such as a vehicle or a ship, for example, a window glass attached to a window opening of a vehicle body panel of an automobile, is provided with a molding which serves as a seal and a decoration at a peripheral portion thereof. More specifically, an elongated gap is continuously formed from the upper portion to the side portion between the peripheral end surface of the window glass and the opening edge of the window opening of the vehicle body panel. The sealing and decoration of the gap are performed by inserting a long molding body into the gap.

[0003] As described above, moldings which are continuously mounted over different portions of an object to be mounted are often formed into a long shape by extrusion, but a general molding is such that the outer surface of the object to be mounted is formed in a belt shape. And a mounting portion that projects from the back side of the decorative portion toward the back side of the mounting target and is fitted to the mounting target.

When manufacturing moldings to be mounted on different parts of the object to be mounted, first, a plurality of moldings having shapes corresponding to different parts of the object to be mounted are individually extruded, and each of them is extruded. It is common practice that a molding body is connected to a long shape via a joint member or the like. However, there are various problems in the decoration or the function in the molding having the connection structure of the plurality of moldings. For example, joint members
When the joint is used, the joint of the joint
Along the corner in advance so that it does not peel off
It is necessary to shape the joint member in a curved shape.
Therefore, the entire molding has a large shape
It is large even if you try to accommodate it in a bent state during transportation and storage.
There is a problem that a large storage space is required. Therefore, conventionally, for example, in JP-A-63-291721 or JP-A-1-244820, a molding having a certain basic shape is first extruded in a series, and a part of the molding is further cut off. There has been proposed one that removes unnecessary portions.

[0005]

However, in such a conventional molding, the molding shape is limited to a shape that can be formed by cutting, and the moldability is limited . That is, in the conventional molding, the mounting compatibility to different parts of the mounting target is not yet sufficient.

On the other hand, Japanese Patent Application Laid-Open No. Sho 62-234814 proposes an apparatus in which the molding shape is apparently changed by adding another part. According to such a means, it is possible to form a shape that cannot be formed by the cutting process, but there is a limit to the formed shape, and the manufacturing process and the combination process for adding parts are increased. As a result, there is a problem that productivity is reduced.

Further, when a core material is provided on the molding, the core material is usually provided over the entire length of the molding. Therefore, in this case, the entire shape of the molding is formed so as to form a non- plastic shape in accordance with the shape of the object to be mounted. In addition, there is a problem that a large mold is required for molding, and a large space is required for storing and transporting the molding.

Accordingly, the present invention provides a molding excellent in compatibility with mounting to different parts of an object to be mounted, and such molding can be performed by simple means.
