Moreover, what is necessary is just to attach 3 A of to-be-adsorbed members to the inner surface of the door 6 of a box, and to attach using the attachment hole 31 with the fasteners 52, such as a screw. In this case, the attracted member 3A to the door 6 can be attracted with a relatively weak attracting force by the second long wall 14 to the second attracting surface 24 of the magnet catch 2.

従って、マグネットキャッチ２と被吸着部材３Ａを使用する場合、マグネットキャッチ２を箱体本体４に取り付ける際に、マグネットキャッチ２の向きを変えることによって、マグネットキャッチ２の吸着力を簡単に変更することができる。また、マグネットキャッチ２は、マグネットケース９にマグネット７とヨーク８とを収納した非常に簡単な構造であり、マグネットキャッチ２を安価かつ容易に製造することができる。しかも、マグネットケース９の第１吸着面２３で被吸着部材３Ａを吸着するようにマグネットケース９を取付部（箱体本体４）に取り付ける位置と、マグネットケース９の第２吸着面２４で被吸着部材３Ａを吸着するようにマグネットケース９を取付部（箱体本体４）に取り付ける位置とが同一位置となり、箱体本体４への締結具５１挿入用の取付孔は１つで済み、マグネットキャッチ２の箱体本体４への取り付け等に非常に便利である。また、マグネットケース９は帯電防止性能を有するため、帯電によってマグネットケース９の表面にほこり等が吸引されて付着するのを未然に防止することができる。 Therefore, when the magnet catch 2 and the attracted member 3A are used, when the magnet catch 2 is attached to the box body 4, the direction of the magnet catch 2 is changed to easily change the attracting force of the magnet catch 2. Can do. The magnet catch 2 has a very simple structure in which the magnet 7 and the yoke 8 are housed in the magnet case 9, and the magnet catch 2 can be manufactured at low cost and easily. In addition, the position where the magnet case 9 is attached to the attachment portion (box body 4) so that the member to be attracted 3A is attracted by the first attracting surface 23 of the magnet case 9, and the second attracting surface 24 of the magnet case 9 is attracted. The position where the magnet case 9 is attached to the attachment portion (box body 4) so as to attract the member 3A is the same position, and only one attachment hole for inserting the fastener 51 into the box body 4 is required. It is very convenient for attachment to the box body 4 of 2. In addition, since the magnet case 9 has antistatic performance, it is possible to prevent dust and the like from being attracted and attached to the surface of the magnet case 9 by charging.

また、マグネットキャッチ２のマグネット７及びヨーク８はマグネットケース９に収納され、マグネットケース９の開口１７を蓋体１８で塞ぐことにより、マグネット７及びヨーク８はマグネットケース９で密封され、マグネット７がマグネットケース９を介して被吸着部材３Ｂと衝当乃至接当するため、マグネット７が直接相手側の被吸着部材３Ｂと衝当乃至接当するようなことがなくなり、連続使用等で起こる金属粉の発生を防ぐことができる。
次に、マグネットキャッチ２と被吸着部材３Ｂとを使用して、箱体本体４に対して扉６を吸着するようにする場合、図２３及び図２４に示すように、マグネットケース９の第１長壁１３（第１吸着面２３）を箱体の扉６に向けて、一対の第２取付片２２をビス等の締付具５１で箱体本体４の天板部５の下面に取り付け、また、被吸着部材３Ｂをマグネットキャッチ２に対応させて箱体の扉６の内面に添わしてビス等の締結具５３により取付孔４６を利用して取り付ければよい。この場合、マグネットキャッチ２の第１長壁１３（第１吸着面２３）で被吸着部材３Ｂ乃至扉６を吸着することができ、マグネットキャッチ２のマグネット７の吸着力と被吸着部材３Ｂのマグネット板３６の吸着力とを重畳させた強い吸着力で吸着することができる。しかも、マグネットキャッチ２のマグネット７及びヨーク８はマグネットケース９に収納され、マグネットケース９の開口１７を蓋体１８で塞ぐことにより、マグネット７及びヨーク８はマグネットケース９で密封され、また、被吸着部材３Ｂのマグネット板３６及びヨーク板３７は被吸着ケース３５に収納され、被吸着ケース３５の開口４１を蓋体４２で塞ぐことにより、マグネット板３６及びヨーク板３７は被吸着ケース３５で密封されており、マグネットキャッチ２と被吸着部材３Ｂとはマグネットケース９の第１長壁（第１吸着壁）１３と被吸着ケース３５の被吸着壁３９とを介して衝当乃至接当するため、金属板が直接相手側と衝当乃至接当するようなことがなくなり、金属粉の発生を確実に防止することができ、クリーンルームでの使用に十分に耐えることができる。また、マグネットケース９及び被吸着ケース３５は帯電防止性能を有するため、帯電によってマグネットケース９及び被吸着ケース３５の表面にほこり等が吸引されて付着するのを未然に防止することができ、この点からもクリーンルームでの使用に適したものになる。 Further, the magnet 7 and the yoke 8 of the magnet catch 2 are accommodated in the magnet case 9, and the magnet 17 and the yoke 8 are sealed by the magnet case 9 by closing the opening 17 of the magnet case 9 with the lid 18. Since the magnet 7 is abutted or contacted with the attracted member 3B via the magnet case 9, the magnet 7 is not directly abutted or brought into contact with the attracted member 3B on the other side. Can be prevented.
Next, when the magnet 6 is attracted to the box body 4 using the magnet catch 2 and the attracted member 3B, as shown in FIG. 23 and FIG. The long wall 13 (first suction surface 23) faces the door 6 of the box, and the pair of second attachment pieces 22 are attached to the lower surface of the top plate portion 5 of the box body 4 with a fastening tool 51 such as a screw. The attracting member 3B may be attached to the inner surface of the box door 6 so as to correspond to the magnet catch 2 and attached using the attachment hole 46 with a fastener 53 such as a screw. In this case, the attracted member 3B to the door 6 can be attracted by the first long wall 13 (first attracting surface 23) of the magnet catch 2, and the attracting force of the magnet 7 of the magnet catch 2 and the magnet plate of the attracted member 3B. Adsorption can be performed with a strong adsorbing force superposed on the adsorbing force of 36. In addition, the magnet 7 and the yoke 8 of the magnet catch 2 are housed in the magnet case 9, and the magnet 17 and the yoke 8 are sealed with the magnet case 9 by closing the opening 17 of the magnet case 9 with the lid 18. The magnet plate 36 and the yoke plate 37 of the attracting member 3B are housed in the attracted case 35, and the magnet plate 36 and the yoke plate 37 are sealed by the attracted case 35 by closing the opening 41 of the attracted case 35 with the lid 42. Since the magnet catch 2 and the attracted member 3B are abutted or contacted via the first long wall (first attracting wall) 13 of the magnet case 9 and the attracted wall 39 of the attracted case 35, The metal plate is not directly in contact with or touching the other side, and the generation of metal powder can be surely prevented. It can sufficiently withstand the use of. In addition, since the magnet case 9 and the attracted case 35 have antistatic performance, it is possible to prevent dust and the like from being attracted and adhered to the surfaces of the magnet case 9 and the attracted case 35 due to charging. From the point of view, it is suitable for use in a clean room.

また、マグネットキャッチ２と被吸着部材３Ｃとを使用して、箱体本体４に対して扉６を吸着するようにする場合、箱体本体４に対して扉６を強い力で吸着する必要があるときには、図２５に示すように、マグネットケース９の第１長壁１３及び第１吸着面２３を箱体の扉６に向けて、一対の第２取付片２２をビス等の締付具５１で箱体本体４の天板部５の下面に取り付け、また、被吸着部材３Ｃをマグネットキャッチ２に対応させて箱体の扉６の内面に添わしてビス等の締結具５４により取付孔４６を利用して取り付ければよい。この場合、マグネットキャッチ２の第１長壁１３（第１吸着面２３）で被吸着部材３Ｃ乃至扉６を強い力で吸着することができる。 Further, when the magnet catch 2 and the attracted member 3C are used to attract the door 6 to the box body 4, it is necessary to attract the door 6 to the box body 4 with a strong force. In some cases, as shown in FIG. 25, the first long wall 13 and the first attracting surface 23 of the magnet case 9 are directed toward the door 6 of the box body, and the pair of second mounting pieces 22 are fastened with a fastening tool 51 such as a screw. The mounting body 46 is attached to the lower surface of the top plate portion 5 of the box body 4, and the attachment member 46 is attached to the inner surface of the door 6 of the box body with the attracted member 3 C corresponding to the magnet catch 2 by a fastener 54 such as a screw. Use and install. In this case, the to-be-adsorbed member 3C thru | or the door 6 can be adsorb | sucked with a strong force with the 1st long wall 13 (1st adsorption | suction surface 23) of the magnet catch 2. FIG.
