の範囲第１項記載の電波暗室用ドア。[Scope of Claim for Utility Model Registration] (1) In a door for an anechoic chamber that opens and closes an opening formed in a wall that constitutes an anechoic chamber by arranging a radio wave absorber on the inner surface of a metal outer wall, one side is covered with a metal plate. The door outer panel has a box-shaped door outer panel having an open surface, and a radio wave absorber provided inside the door outer panel and having unevenness facing the open surface, and the door outer panel has: The whole is formed larger than the opening, and is provided at a different level from the wall so that its open surface faces the opening and overlaps with the wall via the contact part, and 1. A door for a radio anechoic chamber, characterized in that a protective plate having radio wave transparency is provided on the open surface so as to cover the open surface. (2) The contact portion includes a plurality of first protruding plates protruding outward from the metal outer wall, and a plurality of second protruding plates protruding from the door outer plate toward the wall.
and a first projecting plate formed between the first projecting plates so as to mesh with each other alternately.
Utility model registration claim 1, characterized in that a conductive buffer member is fitted into each of the groove portion and the second groove portion formed between the second protruding plate. Door for the anechoic chamber described.
