Claims

[Scope of Claim for Utility Model Registration] 1. Airtightness covering electrical mechanical parts such as an outlet main body, switch main body, or sensor main body inserted into a wiring box that is supported and fixed on the back side of an installation opening opened in a building frame. A box body made of material is formed, and a rigid abutting flange that closely contacts the installation opening periphery is installed on the periphery of the opening of the box body, and an airtight electric wire drawer that allows insertion of electric wires is provided on the bottom wall of the box body. An airtight dustproof device in a wiring box, characterized in that a means is attached thereto. 2. An airtight dust-proof device in a wiring box as set forth in claim 1 of the utility model registration claim, in which a hard material core plate is embedded in the abutting flange. 3. An airtight dust-proof device in a wiring box according to claim 1 or 2 of the utility model registration claim, wherein the wire drawing means is integrally constructed with the box body. 4. An airtight dust-proof device in a wiring box according to claim 1 or 2, wherein the wire drawing means is separate from the box body and made of the same material as the box body so as to be connectable to the box body. 5. The wire drawing means is located on the bottom wall of the box body,
A thick ring-shaped connecting annulus is raised around the penetrable thin film-like closure seal to serve as a pull-out part, and on the other hand,
An appropriate number of presser ribs are raised along the circumferential direction on the circumferential surface of the insertion tube with an inner diameter corresponding to the outer diameter of the wire, and a joint opening to be joined to the connecting ring is provided at the rear of the insertion tube, and a joint opening is provided at the front of the insertion tube. The airtight dust-proofing in the wiring box according to claim 4, which is a utility model registration, in which electric wire draw-out tubes each having an insertion opening closed with a penetrable thin film-like blocking piece are connected to the draw-out portion. Device.
