In the case where only one small protrusion is provided, the attracted plate is supported by the other member at one point by the small protrusion and can swing in all directions. When provided individually, the attracted plate will be supported on the other member at two points by the hemispherical small protrusions,
It is possible to swing in one predetermined direction around these two points, that is, with the straight line connecting these two points as the swing axis. Therefore, even if the accuracy of assembling the other member with respect to one member is poor,
The attracted plate can always be positioned parallel to the surface of the permanent magnet of the attracting member, and a high attracting force can be obtained.
（実施例） 以下、本考案の実施例を添付図面について詳細に説明
する。(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
第１図〜第３図に示すように、永久磁石11の両側に一
対の吸着板12,12を吸着させてなる吸着部材13が設けら
れている。As shown in FIGS. 1 to 3, attraction members 13 formed by attracting a pair of attraction plates 12, 12 are provided on both sides of the permanent magnet 11.
該吸着部材13は、一方部材（例えば第７図の凹部7b参
照）に取付けられる。The suction member 13 is attached to one member (for example, see the recess 7b in FIG. 7).
該吸着部材13に吸着される被吸着板14は、略Ｕ字状に
湾曲された形状でなり、一方の脚部14aには、吸着部材1
3に吸着される平面状の被吸着部14bと、該被吸着部14b
の両端から段状にそれぞれ立下った段部14c,14cとが形
成されている。The attracted plate 14 to be attracted by the attracting member 13 has a substantially U-shaped curved shape, and the attracting member 1 is attached to one leg portion 14a.
The attracted portion 14b having a planar shape that is attracted by 3 and the attracted portion 14b
Stepped portions 14c, 14c are formed so as to fall in a stepwise manner from both ends.
また、被吸着板14の他方の脚部14dには、上記被吸着
部14bの長手方向及び幅方向のほぼ中間で、被吸着部14b
方向へ半球状の打出された小突起14eが形成されてい
る。Further, the other leg portion 14d of the attracted plate 14 is attached to the attracted portion 14b at approximately the middle in the longitudinal direction and the width direction of the attracted portion 14b.
Hemispherical small projections 14e are formed in the direction.
該被吸着板14を取付ける他方の部材（例えば第７図の
トレー８参照）18には、上記被吸着板14の被吸着部14b
の外形状によりやや大き目の開口18aを有する段落部18b
が形成され、該段落部18bの長手方向の両側には切欠き1
8c,18cがそれぞれ形成されている。The other member (for example, the tray 8 in FIG. 7) 18 to which the attracted plate 14 is attached has an attracted portion 14b of the attracted plate 14 described above.
18b having a slightly larger opening 18a due to the outer shape of the
Is formed, and notches 1 are formed on both sides in the longitudinal direction of the paragraph 18b.
8c and 18c are formed respectively.
上記のような構成であれば、他方の部材18に被吸着板
14を取付けるには、被吸着板14の両脚部14a,14dを、一
方の切欠き18cから段落部18bを挟み込むように側方から
差込み、一方の脚部14aを段落部18bの上面側に臨ませ、
他方の脚部14dを段落部18bの背面側に臨ませる。With the above-mentioned configuration, the attracted plate is attached to the other member 18.
To install 14, both legs 14a, 14d of the attracted plate 14 are inserted from the side so that the notch 18c sandwiches the paragraph 18b, and one leg 14a faces the upper surface of the paragraph 18b. No,
The other leg 14d faces the back side of the paragraph 18b.
上記段落部18bの上面にクッション19を設けて、被吸
着板14を上方に付勢すると共に、開口18aの内周面にも
クッション20を設けて、上方に付勢された被吸着板14を
当て止める。A cushion 19 is provided on the upper surface of the paragraph 18b to urge the attracted plate 14 upward, and a cushion 20 is also provided on the inner peripheral surface of the opening 18a so that the attracted plate 14 urged upward. I guess.
上記被吸着板14が上方に付勢されることにより、他方
の脚部14dの小突起14eが段落部18bの背面に接触する。When the attracted plate 14 is biased upward, the small protrusion 14e of the other leg 14d contacts the back surface of the paragraph 18b.
つまり、被吸着板14は他方の部材18に小突起14で一点
支持されることになり、小突起14eを中心にしてあらゆ
る方向に自由に揺動できるようになる。That is, the attracted plate 14 is supported by the other member 18 at one point by the small protrusions 14, and can freely swing in any direction around the small protrusions 14e.
この結果、一方の部材（凹部7b）に対する他方の部材
（トレー８）の組付け精度が悪くても、吸着部材13の永
久磁石11の面と常に平行に被吸着板14の被吸着部14bが
位置するようになるので、高い吸着力が得られるのであ
る。As a result, the attracted portion 14b of the attracted plate 14 is always parallel to the surface of the permanent magnet 11 of the attracting member 13 even if the assembling accuracy of the other member (the tray 8) to the one member (recess 7b) is poor. Since it is located, a high suction force can be obtained.
一方、第４図及び第５図に示す被吸着板24は、平面状
の被吸着部24bと、該被吸着部24bの両端から段状にそれ
ぞれ立下った段部24c,24cとが形成されると共に、各段
部24c,24cには、被吸着部24b方向へ半球状に打出された
小突起24eが形成されている。そして、被吸着板24の一
方の段部24cを、他方の部材18の開口18aから一方の切欠
き18cに差込み、ついで他方の段部24cを他方の切欠き18
cに差込む。On the other hand, the attracted plate 24 shown in FIGS. 4 and 5 has a planar attracted portion 24b and stepped portions 24c, 24c which are stepwise fallen from both ends of the attracted portion 24b. At the same time, each of the stepped portions 24c, 24c is formed with a small protrusion 24e that is hemispherically ejected toward the attracted portion 24b. Then, one step portion 24c of the attracted plate 24 is inserted into the one cutout 18c from the opening 18a of the other member 18, and then the other step portion 24c is inserted into the other cutout 18c.
Insert into c.
上記段落部18bの上面にクッション19を設けて、被吸
着板14を上方に付勢し、各段部24c,24cの小突起24e,24e
を他方の部材18の背面に接触させる。A cushion 19 is provided on the upper surface of the paragraph 18b to urge the attracted plate 14 upward, and the small protrusions 24e, 24e of the step portions 24c, 24c.
Is brought into contact with the back surface of the other member 18.
つまり、被吸着板24は、他方の部材18に小突起24e,24
eで二点支持されることになり、小突起24e,24eを中心に
して幅方向に自由に揺動できるようになる。That is, the attracted plate 24 has small projections 24e, 24 on the other member 18.
Since it is supported by e at two points, it becomes possible to freely swing in the width direction around the small protrusions 24e, 24e.
