し、この段カットは非常に手間のかかる作業であった。In other words, if the decorative covering 56 is present up to the connection end face of the extruded part 51, the decorative covering 56 is grasped and melted when the connecting end of the extruded part 51 is grasped by the mold. However, melting marks and gripping marks are left. Therefore, as shown by a two-dot chain line in FIG. 5, the decorative covering 56x at the connection end is partly attached to the mounting portion 52 and the design lip portion 54.
At the same time, the decorative coating 56 was prevented from being melted by step cutting and removing the connection end portion after the removal by a mold. However, this step cutting was very time-consuming.

Therefore, it is necessary to remove these traces by buffing and hide them. This buffing is also a time-consuming operation, and the decorative covering 56 provided with a grain pattern is also required.
In the case of (1), there is a problem that the grain pattern disappears, and in the case of the decorative covering 56 made of fabric, buffing cannot be performed.

In addition to preventing melting traces and gripping traces from being formed, the load required for elastic deformation of the hollow seal portion of the molded portion is reduced by applying the load of the hollow seal portion of the extruded portion extruded with sponge rubber or sponge TPE. To approach the load.

Therefore, in the present embodiment, the decorative covering 56 at the connection end is left up to the connection end face without being stepped. Therefore, the decorative coating 16 is gripped when the connection end of the extruded portion 11 is gripped by the mold, but since the decorative coating 16 does not have a melting mark or a grip mark, buffing is unnecessary. .
