大変であつた。[Problems to be Solved by the Invention] Although the above-mentioned conventional molding is lightweight due to the presence of the hollow part 8' of the molding, when the upper part of the molding that forms the design surface is pressed, the molding is removed with a slight force. There is a problem that the deing is deformed. For this reason, if a rib is formed inside the portion forming the designed surface to increase the mechanical strength, there is a problem that the formation of the rib causes molding defects to shrink on the designed surface, resulting in poor appearance. Further, since the longitudinal center portion of the molding was formed by extrusion molding, end treatment was required. Separate molding of this terminal portion was expensive and required equipment. In addition, it was difficult to align the terminal parts in order to improve the appearance of the parting part of the terminal part.
本発明は、上記欠点を克服するものであり製造
容易で軽量でかつ見栄えの良いモールデイングを
提供することを目的とする。 The present invention overcomes the above-mentioned drawbacks and aims to provide a molding that is easy to manufacture, lightweight, and has a good appearance.

中空部を持つため軽量である。[Effects of the Invention] In the molding of the present invention, the tips of the ribs protruding from the inner peripheral surface of the base come into contact with the inner peripheral surface of the lid to support the lid. This increases the mechanical strength of the lid. On the other hand, since the ribs are not formed on the inner peripheral surface of the lid, molding defects such as shrinkage do not occur on the design surface of the lid, and the appearance is good. Furthermore, the molding is lightweight because it has a hollow part.

A hinge part 3 that integrally connects one side end and can be bent inward; a set of first engaging parts 4 provided at the other end of the lid part 1 and the other end of the base part 2, respectively; It consists of a second engaging portion 5 and two ribs 10, 10 protruding from the inner circumferential surface side of the base portion 2. The first engaging portion 4 is a convex portion, and the second engaging portion 5 is a concave groove that fits into the convex portion. Note that this molding material is made of polyvinyl chloride. Further, the first engaging portion 4 and the second engaging portion 5 are bonded via an adhesive layer 7 using a urethane adhesive. Further, a shiny member 9 made of metal (stainless steel) is fixedly held on the surface of the lower right end portion of the lid portion 1. The tips of the ribs 10, 10 are the lid part 1.
The cover 1 is in contact with the inner circumferential surface of the cover 1 and supports the cover 1 from the inside.
