ABSTRACT:
An apparatus for testing the waterproofness of a casing having divided casing elements which are connected to each other at opposite end surfaces thereof, includes a dummy casing made from liquid rubber material which has been cured, after a connecting end surface of one of the divided casing elements has been inserted therein, to form a recessed groove corresponding to the connecting end surface. A connecting end surface of one of the divided casing elements is then depressed against the recessed groove of the dummy casing to form a sealed assembly. The waterproofness of the casing can then be determined by determining the waterproofness of the assembly.
