Abstract

PURPOSE: To form the border between the main body part and the knockout part thinner than both parts thereby to cleanly knockout the knockout part without producing burrs.
CONSTITUTION: The knockout part 2 is made thinner than the main body part 1 and further the border between the main body part 1 and the knockout part 2 is made thinner than the knockout part 2. Accordingly, it is possible to cleanly divide the knockout part 2 along the thinned border in both side edges of the knockout 2. Furthermore, when the knockout part is protruded outwardly from the main body part 1, it is preferable because the appearance of the molded article becomes finer.
