It is stated in the No. The louver piece 1 of this louver is generally made of synthetic resin, and its cross-sectional shape is shaped like a letter 7 with a pair of leg pieces joined at the lower end and an open upper part. The wall thickness at this joint portion has a dimension that is the sum of the thickness of the pair of leg portions. That is, the thickness of the joint portion is twice that of the leg portion.

目的しする。(Problem to be Solved by the Invention) However, such a louver piece has a problem in that whiskers often appear on the surface. This kind of sink mark occurs when there is a large change in wall thickness during molding, and as mentioned above, there is a difference in thickness of 2 times, so I tried changing the molding conditions, but it cannot be easily prevented. could not. When such whiskers are used for lighting purposes, there is a problem in that when the lamp is turned on, the whiskers partially shine, spoiling the appearance. The present invention has been made to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a lighting louver that eliminates shrinkage during molding.

厚は徐々に変化するように形成されている。(Example) An example of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes louver pieces combined in a grid pattern. This louver piece 1 is formed into a noodles with a pair of leg pieces 2 joined at the lower end and open at the upper end. Thickness 11 at the upper end of each leg piece 2 and wall thickness 1 at the lower end of the joint 3
2 are formed so as to be spaced apart from each other. Further, the wall thickness 13 at the upper end of the joint 3 is less than twice the thickness 12 of one leg piece 2, and the wall thickness between the upper end of each leg 2 and the upper end of the joint 3 and this joint The wall thickness between the upper end and the lower end of this joint is formed so as to gradually change.
つぎに上記実施例についてざらに詳述すると、たとえば
、脚片２の肉厚寸法は２ｍｍ、接合部３の上端部の肉厚
寸法は３ｍｍまたはそれ以下、接合部３下端の肉厚寸法

である。Next, to explain the above embodiment in detail, for example, the wall thickness of the leg piece 2 is 2 mm, the wall thickness of the upper end of the joint 3 is 3 mm or less, and the wall thickness of the lower end of the joint 3 is 2 mm. It is.
つぎに上記実施例の作用を説明する。接合部３上端部の

たか目立たなくなり、外観が向上する。Next, the operation of the above embodiment will be explained. The thickness dimension 13 of the upper end of the joint 3 is less than twice the thickness I3 of the upper end of one of the leg pieces 2, and the thickness 13 of the lower end of the joint 3
Since 2 is the wall thickness dimension of the upper end of the leg piece 2 and the distance between the legs, the change in wall thickness from the pair of leg pieces 2 to the joint part 3 is gradual.
Therefore, in the molding process, the generation of whiskers is suppressed, and when the lamp is turned on, the lamp does not glow partially or shines less conspicuously, and the appearance is improved.
