的に当接しうるようわん曲して形成されている。 Further, tapered protrusions 4, 4 each having a chevron-shaped cross section are formed at both ends of the shield door 2 on the surfaces facing the frame 1. Further, on the side of the frame 1 facing the protrusion 4, a recess 5 having a chevron-shaped cross section is formed into which the protrusion 4 is loosely fitted. On both inner side surfaces 6, 6 of this recess 5, blocking members 7, 7 made of, for example, copper plates are provided facing each other. Further, the blocking member 7 is formed in a curved manner so that both outer surfaces 8, 8 of the protrusion 4 can resiliently abut against each other.
さらに、第２図に示すようにシールド扉２に設

形成してある。 FIGS. 4 to 6 are schematic diagrams in which the present invention is applied to a double-sided shield door 2'. In this embodiment, as shown in FIG. 4, a recess 5' is formed at the outer edge of the shield door 2', and a protrusion 4 that is loosely fitted into the recess 5' is formed on the frame 1 facing the recess 5'. ' is formed.
なお、前記凹部５′の両内側面６，６には突部
４′の外側面８に密接しうる遮断部材７，７を取
付けておくものとする。 Incidentally, blocking members 7, 7 which can come into close contact with the outer surface 8 of the projection 4' are attached to both inner surfaces 6, 6 of the recess 5'.
