されたり、浮いたりするという欠点があった。As shown in (B) and (C), a positioning abutment 3.3' is formed on the core holder to hold the core element 1 in a predetermined position. This contact part is formed on a protruding cylinder, and the corners 3a and 3'a are rounded as shown in FIGS. 1(B) and (C), so that the core element 1 is When it comes into contact with the parts 3a and 3'a, the first
As shown in Figure (C), there was a drawback that the core element 1 was positioned bent or floated.
［目 的］
従って本発明はこのような従来の欠点を除去すると同時

ルダ２に対し正しく位置決めすることができる。Other embodiments are illustrated in FIGS. 3 and 4.
In the embodiments of Figures (A), (B) and (C), the perforation grooves 6, 6'
has a semicircular shape, and Fig. 4 (A), (B), '
In the embodiment (C), it is formed into a rectangular shape. In either embodiment, the core element 1 can be correctly positioned with respect to the core holder 2 as in FIG. 2.
以上水した実施例の他に逃し溝の形状は六角形状のよう
