1. An engagement structure of a waterproof connector comprising:a connector housing having a plurality of terminal accommodation chambers formed therein, the terminal accommodation chambers being chambers into which a terminal connected with a wire is to be inserted, the connector housing further having a plurality of rubber plug accommodation recesses formed therein, the rubber plug accommodation recesses being formed at positions opposed to the terminal accommodation chambers, the connector housing having one wall portion at an end opposed to the terminal accommodation chambers, and the one wall portion having wire insertion and passing-through holes configured to pass the wire therethrough, the rubber plug accommodation recesses being greater in cross section than the wire insertion and passing-through holes of the one wall portion; rubber plugs respectively inserted forcibly into the plurality of rubber plug accommodation recesses such that each rubber plug substantially fills each accommodation recess and each accommodation recess is separated from other accommodation recesses by separation walls, the rubber plugs being respectively formed with wire insertion and passing-through holes configured to pass the wire therethrough; and a dummy plug having a shaft portion configured to be inserted into and to seal the wire insertion and passing-through hole of the rubber plug, the dummy plug further having a flange portion and at lease one engaging protrusion protruding from the shaft portion, the flange portion being greater in cross section than the wire insertion and passing-through hole of the one wall portion and being separated from the engaging protrusion such that a portion of the one wall portion around the wire insertion and passing-through hole of the one wall portion is sandwiched between the flange portion and the engaging protrusion when the shaft portion is inserted into the wire insertion and passing-through hole of the rubber plug and the wire insertion and passing-through hole of the one wall portion.
