本発明は、自動車のエンジンルームやトランクルームに
設けられるフード（リッド）の軽量化技術に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a technology for reducing the weight of a hood (lid) provided in an engine room or trunk room of an automobile.
（従来の技術）
従来の自動車用フードとしては、例えば特開昭６０−２
１９１６５号公報に記載されたものが知られている。(Prior art) As a conventional automobile hood, for example, Japanese Patent Application Laid-Open No. 60-2
The one described in Japanese Patent No. 19165 is known.

設した構造となっていた。As a means of reducing the weight of automobiles, this conventional product is made by molding the automobile hood, which is generally rectangular in overall shape, from a plastic plate instead of a steel plate. The hinge attachment formed at both ends of the circumferential edge rib and the bottom edge of the plastic plate had a structure in which V-shaped ribs were integrally molded and protruded along the line connecting the parts.
（発明が解決しようとする問題点）
しかしながら、上述の従来品では、第４図に示すように

すると、十分な補強強度を得るためにはリブの数を増さ
なければならず、これでは成形時の型抜きが難かしくな
るという問題が生じる。(Problems to be Solved by the Invention) However, in the conventional product described above, as shown in FIG. There are dents (sink marks) 10 on the surface of the plastic plate 100 at certain points.
4 may occur, and if this occurs, it will be necessary to apply putty or the like during surface finishing to repair it.In order to prevent the above-mentioned dents 104, reducing the width of the ribs will allow sufficient In order to obtain reinforcement strength, it is necessary to increase the number of ribs, which causes the problem that it becomes difficult to cut out the mold during molding.
又、射出成形等により成形したプラスチック板を用いる
