To provide an automatic door structure using a magnet easy to assemble and easy to remove a door.SOLUTION: A plurality of fixed side magnets 3 are fixed to a door frame 1 with one magnetic poles arranged toward an opening 13 side of the door frame 1. A plurality of door side magnets 4 are fixed to an edge part 21 of a door material 2, and attracted by magnetic forces to the magnetic poles of the respective fixed side magnets 3 so as to be openably/closably held at a position where the door material 2 is closed. Each of the fixed side magnets 3 and each of the door side magnets 4 are composed of spheres of the same size. The door material 2 and the door frame 1 have a shaft material 7 and a bearing rotatable with each other on an upper surface and a lower surface, respectively. The rotation center line of each of the shaft member 7 and the bearing passes through the center of each door side magnet 4.SELECTED DRAWING: Figure 1
【課題】組立て容易でかつドアの取外しが容易な磁石利用自動ドア構造を提供する。【解決手段】複数の固定側磁石３が一方の磁極をドア枠１の開口１３側に向けて配置してドア枠１に固定される。複数の各ドア側磁石４がドア材２の縁部２１に固定され、ドア材２を閉じる位置で開閉可能に保持するようそれぞれ各固定側磁石３の磁極に磁力で吸引されている。各固定側磁石３および各ドア側磁石４はそれぞれ同一の大きさの球体から成る。ドア材２およびドア枠１は、それぞれ上面および下面に、互いに回転可能な軸材７および軸受けを有する。軸材７および軸受けの回転中心線は各ドア側磁石４の中心を通る。【選択図】図１
