PROBLEM TO BE SOLVED: To provide a closing-up device for closing up apertures for wiring formed at a dustproof type casing for housing electric parts, which is capable of closing up the apertures for wiring formed at the dustproof type casing for housing electric parts with a sufficient hermetic degree regardless of the external diameter and the number of wires of the wiring and the sectional shapes of the bundles of the wiring. SOLUTION: The closing-up device has box-shaped cover members 46 and 64 which are mounted to cover the apertures on the outside surface of the dustproof type casing having the apertures 40H and 52A formed and soft packing materials 50 and 62 which are arranged within the recessed parts of the cover members. The closing-up device is so constituted that the packing materials 50 and 62 hermetically close the circumferences of the wiring 44 and 58.
