Abstract
Provided is an apparatus for testing waterproofness of a half-finished product, wherein the apparatus is configured to form a chamber space such that areas of holes and parts of the half-finished product are separated from each other, and high-pressure air is injected into the chamber space, thereby performing a waterproofness test. In addition, a sliding block is provided such that a hole blocking means blocking the holes of the half-finished product is moved forward and backward through engagement and disengagement of a body and a cover without requiring a separate power, and the apparatus includes the body, the cover, a sealing means, and a hole blocking means including a sliding block moved in a lateral direction of the half-finished product, a blocking member blocking a side hole of the holes, and a pushing member pushing the sliding block to be moved forward when the body and the cover are combined.
