An electromagnetic shielding material 71 that forms an electromagnetic shield in contact with the conductive floor member 41 formed on the floor surface is formed on the bottom surface without interruption in the width direction, and the steadying wheel 63 slides. A guide groove 72 is provided.

  The operation of the electromagnetic shielding door having the above configuration will be described. First, when the sliding door body 31 is open, the sliding door body 31 is installed with the entire sliding door body 31 suspended while the wheels 66 are placed on the rails 38. The contact piece 58 is not in contact with the electromagnetic shield material 56 of the shield material mounting frame 59 attached to the Kamoi horizontal column 65, the electromagnetic shield material 71 of the sill portion is not in contact with the conductive floor member 41, and The conductive contact piece 58 is not in contact with the electromagnetic shield material 56 even at the boundary portion with the door pocket 33. Therefore, in the state where the sliding door main body 31 is open, the member used for the electromagnetic shield does not come into contact with the corresponding conductive member, and no electromagnetic shielding is performed.

  Next, when the sliding door main body 31 is closed, the driving device 42 is driven to rotate the gear 43, thereby providing the central portion of the side surface of the sliding door main body 31 through the chain 46, the gear 44, the chain 47, and the gear 45. Power is transmitted by the chain 47 to the fastening portion 49 of the connecting member 48 thus closed, and the sliding door body 31 is closed. At this time, the sliding door body 31 moves as the wheel 66 rolls on the rail 38, but each member used for the electromagnetic shield does not come into contact with the corresponding conductive member even in the closing process. When the sliding door body 31 is slid to the fully closed position, the wheel 66 sinks into the concave portion 39 on the rail 38, and the two sliding door bodies 31 are summoned. Thus, when the wheel 66 sinks into the concave portion 39 on the rail 38, the entire sliding door body 31 moves vertically downward by the depth of the concave portion 39. As a result, the conductive contact of the duck portion is achieved. The piece 58 contacts the electromagnetic shielding material 56 of the shielding material mounting frame 59 attached to the Kamoi horizontal column 65, the electromagnetic shielding material 71 of the sill portion contacts the conductive floor member 41, and the boundary portion with the door pocket 33. The conductive contact piece 58 is also in contact with the electromagnetic shield material 56 in FIG. Further, even at the portion where the two sliding door main bodies 31 are summoned, the conductive contact piece 58 provided on one sliding door main body 31 contacts the electromagnetic shield material 56 provided on the other sliding door main body 31. Therefore, when the sliding door main body 31 is completely closed, the electromagnetic shield is applied to all of the summit portion, the sill portion, the boundary portion between the door pocket 33 and the two sliding door main bodies 31 and the shield leakage. It does not occur.

  As described above, when the sliding door main body 31 is open and during the sliding operation, the member used for the electromagnetic shield does not come into contact with the corresponding conductive member, so that the electromagnetic shielding member is damaged by friction or catching. When the sliding door main body 31 is closed, the member used for the electromagnetic shield comes into contact with the corresponding conductive member, the duck portion, the sill portion, the boundary portion with the door pocket 33, and the two sliding door main bodies 31 of the summing portion. All are electromagnetically shielded.

  In the said Example, although demonstrated as an example the case where it comprised as a double-opening type using the two sliding door main bodies 31, this invention is not restricted to this, It employ | adopts also when comprised as a single-opening type. Is something that can be done. In this case, for example, by applying the configuration adopted in the summing portion of the two sliding door main bodies 31 in the first embodiment to the boundary between the single sliding door main body 31 and the indoor pillar 60, the same applies to the single-open type. It becomes possible to comprise.

  Moreover, in the said Example, as shown in FIG. 1 as an example comprised as an automatic door, although it comprised, providing the drive device 42 etc. in the wall surface of the door pocket 33, this invention is not limited to this, It may be a manual door. In this case, the pulling bar 51 is used when the sliding door main body 31 that has fallen down as a result of the wheel 36 being fitted in the recess 39 is lifted onto the rail 38.
