ABSTRACT:
An object of the present invention is to improve operability. Stoppers (74) are detachably mounted in a lower mold (70) of a mold. Nuts (30) are screwed down onto the stoppers (74) while being held upside down. After the mold is closed in this state and molten resin is filled into a cavity (77) and solidified therein, the mold is opened. The stoppers (74) are separated from the lower mold (70) as the mold is opened. When the stoppers (74) are separated from the nuts (30) thereafter, a casing10having no pin withdrawal hole can be obtained. Accordingly, it is not necessary to apply potting or the like to close the pin withdrawal hole.
