この考案は保持具に関し、特にたとえば、鉄、鋼またはその他の磁性材で形成 されたワーク等の物品を磁気的に吸着して所定の位置に着脱自在に保持すること ができる、保持具に関する。 The present invention relates to a holder, and more particularly, to a holder capable of detachably holding an article such as a work made of iron, steel or other magnetic material at a predetermined position by magnetically attracting the article.

図8はこの考案の背景となる従来の搬送ジグの一例を示す断面図解図である。 この搬送ジグ1は、たとえば帽子状のホルダー3を含む。ホルダー3は、その中 央上部に平面円形の凹み部5を有する。また、ホルダー3の中央には、ピン7が 支持される。ピン7は、その軸方向の先端部7aがホルダー3の上端面から突出 するように、ホルダー3に支持される。 さらに、ホルダー3の凹み部5には、たとえば円環状のゴム磁石9が装着され る。ゴム磁石9は、その表面に磁気を具備するものであり、ゴム磁石9の孔9a にピン7の先端部7aを挿通させて、凹み部5に磁気的に吸着される。 FIG. 8 is an illustrative sectional view showing an example of a conventional transport jig as a background of the present invention. The transport jig 1 includes, for example, a hat-shaped holder 3. The holder 3 has a flat circular recess 5 at the center upper part. In the center of the holder 3, a pin 7 is supported. The pin 7 is supported by the holder 3 so that its axial tip 7a protrudes from the upper end surface of the holder 3. Further, for example, an annular rubber magnet 9 is mounted in the concave portion 5 of the holder 3. The rubber magnet 9 has magnetism on its surface. The tip 9 a of the pin 7 is inserted through the hole 9 a of the rubber magnet 9, and is magnetically attracted to the recess 5.
【0003】 このホルダー3は、その上面に、たとえばスピーカーの底部材などのワークW (被加工物)が磁気的に吸着保持され、適宜、加工作業などが施される。そして 、加工作業などが終了すれば、ゴム磁石9の吸着面から、ワークWが取り外され る。A work W (workpiece) such as a bottom member of a speaker is magnetically attracted and held on an upper surface of the holder 3, and a processing operation or the like is appropriately performed. Then, when the processing operation or the like is completed, the work W is removed from the attraction surface of the rubber magnet 9.
【0004】[0004]
しかしながら、図8に示す従来の搬送ジグでは、ゴム磁石9の磁力が大き過ぎ ると、ゴム磁石9の吸着面に残留磁気が発生し、ワークWを持ち上げて吸着面か ら取り外す時に、ワークWがピン7を介してホルダー3と共に外れてしまう恐れ があった。一方、ゴム磁石9の磁力が小さ過ぎると、ワークWを磁気的に吸着す る吸着力が低下し、ワークWへの加工作業を施す際に、ワークWが吸着面からず れてしまい、ワークWへの作業効率が低下する。 However, in the conventional transfer jig shown in FIG. 8, if the magnetic force of the rubber magnet 9 is too large, residual magnetism is generated on the attraction surface of the rubber magnet 9, and when the work W is lifted and removed from the attraction surface, the work W However, there is a danger that it will come off with the holder 3 via the pin 7. On the other hand, if the magnetic force of the rubber magnet 9 is too small, the attraction force for magnetically attracting the work W is reduced, and the work W is displaced from the attracting surface when performing a working operation on the work W. Work efficiency to W decreases.
【0005】 それゆえに、この考案の主たる目的は、簡単に被吸着物を所定の位置に磁気的 に強固に吸着して固定することができ、且つ、簡単に吸着力を解除して被吸着物 を取り外すことができる、保持具を提供することである。Therefore, a main object of the present invention is to easily and firmly magnetically adsorb and fix an object to be adsorbed at a predetermined position, and to easily release the adsorbing force to easily fix the object to be adsorbed. The object of the present invention is to provide a holder which can be detached.

【0008】 第2の摺動ヨーク部は、平面状の磁性体で形成されることが好ましい。この場 合、第2の摺動ヨーク部は、例えば平面板に形成できるので、製造しやすいもの となる。また、第2の摺動ヨーク部は、磁性体と非磁性体とを交互に隣接して面 状に形成し、しかも、第2の摺動ヨーク部を磁力発生ヨーク部の一方主面上に対 向配置させた場合に、第2の摺動ヨーク部の磁性体が磁力発生ヨーク部の磁性体 に対して格子状に配置されるように形成することもできる。Preferably, the second sliding yoke portion is formed of a planar magnetic body. In this case, since the second sliding yoke portion can be formed, for example, on a flat plate, it is easy to manufacture. The second sliding yoke portion is formed by alternately forming a magnetic material and a non-magnetic material in a plane adjacent to each other, and furthermore, the second sliding yoke portion is formed on one main surface of the magnetic force generating yoke portion. In the case where the magnetic members of the second sliding yoke are arranged in the opposite direction, the magnetic members of the second sliding yoke may be arranged in a grid pattern with respect to the magnetic members of the magnetic force generating yoke.

【0013】[0013]
摺動部の第1の摺動ヨーク部ないし第2の摺動ヨーク部は、摺動手段で摺動自 在に変位されることによって、磁力発生ヨーク部の一方主面上に選択的に対向配 置される。 The first sliding yoke and the second sliding yoke of the sliding portion are selectively displaced by the sliding means so as to selectively oppose one main surface of the magnetic force generating yoke. Deployed.
【0014】 摺動手段によって、磁力発生ヨーク部の一方主面上に摺動部の第1の摺動ヨー ク部が対向配置されると、磁力発生ヨーク部の磁石体の磁極(N極)から出た磁 束は、磁力発生ヨーク部の磁性体から第1の摺動ヨーク部の磁性体および固定ヨ ーク部の磁性体へと通って、固定ヨーク部の他方主面側に流れ、さらに、固定ヨ ーク部の磁性体から第1の摺動ヨーク部の磁性体および磁力発生ヨーク部の磁性 体を通って磁石体の磁極(S極)に入る。そのため、固定ヨーク部の他方主面側 には、磁石体からの磁力が作用して、磁界が発生する。 したがって、固定ヨーク部の他方主面側にたとえばワークなどの被吸着物を載 置すると、磁石体の磁極(N極)から出た磁束が被吸着物の中を通って磁石体の 磁極(S極)に入るので、固定ヨーク部の他方主面側に被吸着物が磁気的に吸着 されることになる。When the first sliding yoke portion of the sliding portion is opposed to the one main surface of the magnetic force generating yoke portion by the sliding means, the magnetic pole (N pole) of the magnet body of the magnetic force generating yoke portion From the magnetic body of the magnetic force generating yoke, flows to the magnetic body of the first sliding yoke and the magnetic body of the fixed yoke, and flows to the other main surface side of the fixed yoke. Further, the magnetic material of the fixed yoke portion enters the magnetic pole (S-pole) of the magnet body through the magnetic material of the first sliding yoke portion and the magnetic material of the magnetic force generating yoke portion. Therefore, a magnetic force from the magnet body acts on the other main surface side of the fixed yoke portion, and a magnetic field is generated. Therefore, when an object to be attracted, such as a work, is placed on the other main surface side of the fixed yoke portion, the magnetic flux emitted from the magnetic pole (N pole) of the magnet passes through the object and the magnetic pole (S ), The object to be attracted is magnetically attracted to the other main surface side of the fixed yoke portion.
【0015】 また、摺動手段によって、磁力発生ヨーク部の一方主面上に摺動部の第2の摺 動ヨーク部が対向配置されると、磁石体の磁極(N極)から出た磁束は、磁力発 生ヨーク部の磁性体から第2の摺動ヨーク部の磁性体を通って、再び、磁力発生 ヨーク部の磁性体に流れ、磁石体の磁極(S極)に入る。この場合、磁束の流れ は、磁力発生ヨーク部および第2の摺動ヨーク部内に閉鎖されるため、固定ヨー ク部の他方主面側には、磁化力が働かない。Further, when the second sliding yoke portion of the sliding portion is opposed to the one main surface of the magnetic force generating yoke portion by the sliding means, the magnetic flux emitted from the magnetic pole (N pole) of the magnet body. Flows from the magnetic material of the magnetic force generating yoke to the magnetic material of the magnetic force generating yoke through the magnetic material of the second sliding yoke, and enters the magnetic pole (S pole) of the magnet. In this case, since the flow of the magnetic flux is closed in the magnetic force generating yoke portion and the second sliding yoke portion, no magnetizing force acts on the other main surface side of the fixed yoke portion.
【0016】 位置決め手段は、第1の摺動ヨーク部ないし第2の摺動ヨーク部の中心位置が 磁力発生ヨーク部の中心位置と重なり合うように、第1の摺動ヨーク部ないし第 2の摺動ヨーク部を磁力発生ヨーク部の一方主面上に位置決めする。そのため、 摺動部の第1の摺動ヨーク部ないし第2の摺動ヨーク部を簡単に且つ正確に磁力 発生ヨーク部の一方主面上に対向配置させることができる。The positioning means is arranged so that the center position of the first sliding yoke portion or the second sliding yoke portion overlaps the center position of the magnetic force generating yoke portion. The moving yoke is positioned on one main surface of the magnetic force generating yoke. Therefore, the first and second sliding yoke portions of the sliding portion can be simply and accurately opposed to one main surface of the magnetic force generating yoke portion.
【0017】 磁力発生ヨーク部と第2の摺動ヨーク部との間に間隙部を形成すると、磁力発 生ヨーク部と第2の摺動ヨーク部との間に空気層が形成される。この場合、磁力 発生ヨーク部の磁石体の磁極からでた磁束は、この空気層を通って第2の摺動ヨ ーク部の磁性体へと流れ、再び、この空気層を通って磁力発生ヨーク部の磁石体 の磁極へと流れるが、空気中には磁束が通りにくいため、摺動部の第2の摺動ヨ ーク部に作用する磁力発生ヨーク部の磁気的吸引力が小さくなる。そのため、磁 力発生ヨーク部の一方主面上に第2の摺動ヨーク部を対向配置したときの摺動部 の摺動が容易になる。When a gap is formed between the magnetic force generating yoke and the second sliding yoke, an air layer is formed between the magnetic force generating yoke and the second sliding yoke. In this case, the magnetic flux from the magnetic pole of the magnet body of the magnetic force generating yoke portion flows through the air layer to the magnetic material of the second sliding yoke portion, and again passes through the air layer to generate the magnetic force. Although it flows to the magnetic poles of the magnet body of the yoke, the magnetic flux does not easily pass through the air, so the magnetic attraction of the magnetic force generating yoke acting on the second sliding yoke of the sliding part is reduced. . Therefore, sliding of the sliding portion when the second sliding yoke portion is opposed to one main surface of the magnetic force generating yoke portion is facilitated.
【0018】[0018]
この考案にかかる保持具では、簡単に被吸着物を所定の位置に磁気的に強固に 吸着して固定することができ、且つ、簡単に吸着力を解除して被吸着物を取り外 すことができる。特に、この考案にかかる保持具では、摺動部を摺動手段により 摺動変位させ、第2の摺動ヨーク部を磁力発生ヨーク部上に対向配置させた場合 、磁力発生ヨーク部と第2の摺動ヨーク部との間で、磁気回路が閉ループを構成 するため、被吸着物を磁気的に吸着して保持する保持面には、磁力発生ヨーク部 からの磁束の流れがほぼ完全に遮断される。すなわち、この考案にかかる保持具 では、従来品と比較して、被吸着物保持面に残留する残留磁束密度を極端に少な くすることができるので、被吸着物保持面からの被吸着物の取り外しが至極簡単 に行われる。 With the holder according to the present invention, the object to be adsorbed can be easily magnetically firmly attracted to a predetermined position and fixed, and the object to be attracted can be easily removed by releasing the attraction force. Can be. In particular, in the holder according to the present invention, when the sliding portion is slid and displaced by the sliding means and the second sliding yoke portion is disposed opposite to the magnetic force generating yoke portion, the magnetic force generating yoke portion and the second sliding yoke portion can be displaced. Since the magnetic circuit forms a closed loop with the sliding yoke, the magnetic flux from the magnetic force generating yoke is almost completely blocked on the holding surface that magnetically attracts and holds the object to be attracted. Is done. That is, in the holder according to the present invention, the residual magnetic flux density remaining on the object-holding surface can be extremely reduced as compared with the conventional product. Removal is extremely easy.

The magnetic members 64a to 64f of the yoke portion 60 pass through the magnetic members 44a to 44f of the first sliding yoke portion 40 and the magnetic members 32a to 32f of the magnetic force generating yoke portion 22 to pass through each of the magnets 28a to 28e. Enter the pole. Therefore, the magnetic force from the magnet bodies 28a to 28e acts on the upper surface side of the fixed yoke portion 60, and a magnetic field is generated. Therefore, when an object W such as a work is placed on the upper surface side of the fixed yoke portion 60, the magnetic fluxes emitted from the respective N poles of the magnets 28a to 28e pass through the object W and pass through the object W. Since it enters the magnetic pole (S pole), the object W 2 is magnetically attracted to the upper surface of the fixed yoke portion 60.
【0041】 この考案の実施の形態例で示した保持具10では、磁力発生ヨーク部22の磁 性部材32b〜32eを間に挟んで隣合う5つの磁石体28a〜28eの磁極が 同じ極性であるため、磁石体28a〜28eの各N極から出る磁束のほとんど全 部を有効的に固定ヨーク部60の上面に作用させることができ、つまり、磁束密 度を大きくして、磁気的な吸着力を高めることができる。 そのため、固定ヨーク部60の上面に載置されたワークなどの被吸着物Wは、 磁気的に強固に吸着される。In the holder 10 shown in the embodiment of the present invention, the magnetic poles of the five magnet bodies 28 a to 28 e adjacent to each other with the magnetic members 32 b to 32 e of the magnetic force generating yoke portion 22 interposed therebetween have the same polarity. Therefore, almost all of the magnetic flux emitted from each of the N poles of the magnet bodies 28a to 28e can be effectively applied to the upper surface of the fixed yoke portion 60. That is, the magnetic flux density is increased and the magnetic attraction is increased. Power can be increased. Therefore, the object W to be attracted such as a work placed on the upper surface of the fixed yoke portion 60 is strongly attracted magnetically.
【0042】 また、この考案の実施の形態例で示した保持具10では、固定ヨーク部60の 上面から被吸着物Wを取り外す場合、たとえば図1および図5(B)などに示す ように、摺動板34の操作部38aないし38bを操作して、第2の摺動ヨーク 部48を摺動通路14aの長さ方向の他方から一方へ摺動変位させることによっ て、基台12の磁力発生ヨーク部22の上面に摺動板34の第2の摺動ヨーク部 48を対向配置させた状態にする。すなわち、磁力発生ヨーク部22の中心位置 と第2の摺動ヨーク部48の中心位置とが重なり合う状態になる。また、磁力発 生ヨーク部22の磁性部材32a〜32fおよび非磁性部材30a〜30eの上 端面全面と第2の摺動ヨーク部48の下端面全面との間には、摺動板34の段差 部50によって、空気層としての間隙部68が形成される。In the holder 10 shown in the embodiment of the present invention, when the object W is removed from the upper surface of the fixed yoke portion 60, for example, as shown in FIG. 1 and FIG. By operating the operating portions 38a and 38b of the sliding plate 34 to displace the second sliding yoke portion 48 from the other side in the longitudinal direction of the sliding passage 14a to one side, the base 12 The second sliding yoke portion 48 of the sliding plate 34 is arranged to face the upper surface of the magnetic force generating yoke portion 22. That is, the center position of the magnetic force generating yoke portion 22 and the center position of the second sliding yoke portion 48 overlap each other. Also, a step of the sliding plate 34 is provided between the entire upper end surfaces of the magnetic members 32a to 32f and the nonmagnetic members 30a to 30e of the magnetic force generating yoke portion 22 and the entire lower end surfaces of the second sliding yoke portions 48. The part 50 forms a gap part 68 as an air layer.
【0043】 この場合、磁力発生部22の磁石体28a〜28eの各N極から出た磁束は、 磁力発生ヨーク部22の磁性部材32a〜32fから、間隙部68を介して、第 2の摺動ヨーク部48へと流れ、再び、間隙部68を介して、磁力発生ヨーク部 22の磁性部材32a〜32fに流れ、磁石体の28a〜28eの各S極へと入 る。このとき、磁束の流れは、磁力発生ヨーク部22および第2の摺動ヨーク部 48内に閉鎖されるため、固定ヨーク部60の上面側には磁化力が働かない。つ まり、固定ヨーク部60の上面側に作用していた磁化力を零にして、磁気的な吸 着力を解放することができる。したがって、摺動板34を操作するだけで、簡単 に、固定ヨーク部60の上面に吸着している被吸着物Wを取り外すことができる 。In this case, the magnetic flux emitted from each of the N poles of the magnet bodies 28 a to 28 e of the magnetic force generating part 22 is transferred from the magnetic members 32 a to 32 f of the magnetic force generating yoke part 22 via the gap 68 via the second sliding member. It flows to the moving yoke portion 48, flows again through the gap portion 68 to the magnetic members 32a to 32f of the magnetic force generating yoke portion 22, and enters the respective south poles of the magnet bodies 28a to 28e. At this time, since the flow of the magnetic flux is closed in the magnetic force generating yoke portion 22 and the second sliding yoke portion 48, no magnetizing force acts on the upper surface side of the fixed yoke portion 60. In other words, the magnetic force acting on the upper surface side of the fixed yoke portion 60 can be reduced to zero to release the magnetic attraction force. Therefore, only by operating the slide plate 34, the object W to be sucked on the upper surface of the fixed yoke portion 60 can be easily removed.
【0044】 この考案の実施の形態例で示した保持具10では、特に、磁力発生ヨーク部2 2と第2の摺動ヨーク部48との間に間隙部68が形成されているため、磁力発 生ヨーク部22と第2の摺動ヨーク部48との間に空気層が形成される。この場 合、磁力発生ヨーク部22の磁石体28a〜28eのN極からでた磁束は、この 空気層を通って第2の摺動ヨーク部48へと流れ、再び、この空気層を通って磁 力発生ヨーク部22の磁石体28a〜28eのS極へと流れるが、空気中には磁 束が通りにくいため、第2の摺動ヨーク部48に作用する磁力発生ヨーク部22 の磁気的吸引力が小さくなる。そのため、磁力発生ヨーク部22の上面に第2の 摺動ヨーク部48を配置したときの摺動板34の摺動が容易になる。In the holder 10 shown in the embodiment of the present invention, in particular, since the gap 68 is formed between the magnetic force generating yoke portion 22 and the second sliding yoke portion 48, the magnetic force An air layer is formed between the generating yoke part 22 and the second sliding yoke part 48. In this case, the magnetic flux generated from the N poles of the magnets 28a to 28e of the magnetic force generating yoke portion 22 flows through the air layer to the second sliding yoke portion 48, and again passes through the air layer. Although it flows to the S poles of the magnet bodies 28a to 28e of the magnetic force generating yoke 22, the magnetic flux hardly passes through the air, so that the magnetic force of the magnetic force generating yoke 22 acting on the second sliding yoke 48 is reduced. The suction force decreases. Therefore, the sliding of the sliding plate 34 when the second sliding yoke portion 48 is disposed on the upper surface of the magnetic force generating yoke portion 22 becomes easy.
【0045】 この考案にかかる保持具10では、簡単に被吸着物Wを所定の位置に磁気的に 強固に吸着して固定することができ、且つ、簡単に吸着力を解除して被吸着物W を取り外すことができる。特に、この考案にかかる保持具10では、摺動板34 を摺動変位させ、第2の摺動ヨーク部48を磁力発生ヨーク部22上に配置させ た場合、磁力発生ヨーク部22と第2の摺動ヨーク部48との間で、磁気回路が 閉ループを構成するため、被吸着物Wを磁気的に吸着して保持する固定ヨーク部 60上面には、磁力発生ヨーク部22からの磁束の流れがほぼ完全に遮断される 。この場合、固定ヨーク部60上面に残留する残留磁束密度を極端に少なくする ことができるので、固定ヨーク部60上面からの被吸着物Wの取り外しが至極簡 単に行われる。In the holder 10 according to the present invention, the object W can be easily magnetically and firmly attracted and fixed at a predetermined position, and the attracting force can be easily released and the object W can be easily released. W can be removed. In particular, in the holder 10 according to the present invention, when the sliding plate 34 is slid and displaced and the second sliding yoke portion 48 is disposed on the magnetic force generating yoke portion 22, the magnetic force generating yoke portion 22 and the second Since the magnetic circuit forms a closed loop with the sliding yoke part 48, the fixed yoke part 60 that magnetically attracts and holds the object W to be attracted is provided on the upper surface of the fixed yoke part 60 with the magnetic flux from the magnetic force generating yoke part 22. The flow is almost completely shut off. In this case, since the residual magnetic flux density remaining on the upper surface of the fixed yoke portion 60 can be extremely reduced, the removal of the object W from the upper surface of the fixed yoke portion 60 can be performed extremely easily.
【0046】 図6は、この考案の他の実施の形態の例を示す要部拡大分解斜視図である。図 6に示す保持具10では、図1〜図5に示す保持具10と比べて、特に、摺動板 34の第2の摺動ヨーク部48の構成が相違するものである。図1〜図5に示す 保持具10では、第2の摺動ヨーク部48が磁性体で平面状に形成されたが、図 6に示す保持具10では、第2の摺動ヨーク部70が磁性体と非磁性体とが交互 に隣接して縞状に形成されている。 すなわち、図6に示す保持具10では、第2の摺動ヨーク部70が、たとえば 矩形の6つの磁性体からなる磁性部材72a,72b,72c,72d,72e および72fと、たとえば矩形の5つの非磁性体からなる非磁性部材74a,7 4b,74c,74dおよび74eとで構成される。6つの磁性部材72a〜7 2fと5つの非磁性部材74a〜74eとは、その幅方向に交互に隣接して縞状 に配設される。この第2の摺動ヨーク部70は、その磁性部材72a〜72fお よび非磁性部材74a〜74eが、磁力発生ヨーク部22の磁性部材32a〜3 2fおよび非磁性部材30a〜30eに対して、平面的に見て、格子状に配置さ れるように形成される。FIG. 6 is an enlarged exploded perspective view of a main part showing an example of another embodiment of the present invention. The holder 10 shown in FIG. 6 differs from the holder 10 shown in FIGS. 1 to 5 particularly in the configuration of the second sliding yoke portion 48 of the sliding plate 34. In the holder 10 shown in FIGS. 1 to 5, the second sliding yoke part 48 is formed of a magnetic material in a planar shape. However, in the holder 10 shown in FIG. The magnetic material and the non-magnetic material are alternately adjacently formed in stripes. That is, in the holding tool 10 shown in FIG. 6, the second sliding yoke portion 70 includes, for example, five rectangular magnetic members 72a, 72b, 72c, 72d, 72e, and 72f, and five rectangular It is composed of non-magnetic members 74a, 74b, 74c, 74d and 74e made of non-magnetic material. The six magnetic members 72a to 72f and the five non-magnetic members 74a to 74e are arranged alternately and adjacently in the width direction in a stripe shape. The second sliding yoke portion 70 is such that the magnetic members 72a to 72f and the non-magnetic members 74a to 74e are different from the magnetic members 32a to 32f and the non-magnetic members 30a to 30e of the magnetic force generating yoke portion 22. It is formed so as to be arranged in a grid when viewed in plan.
【0047】 図6に示す保持具10では、固定ヨーク部60の上面に被吸着物Wを磁気的に 吸着保持する場合には、たとえば図1および図5(A)などで示したように、図 1〜図5に示す実施の形態例と同様の作用効果を有するものである。 また、図6に示す保持具10において、固定ヨーク部60の上面から被吸着物 Wを取り外す場合には、図6および図7に示すように、摺動板34の操作部38 aないし38bを操作して、第2の摺動ヨーク部70を基台12の磁力発生ヨー ク部22の上面に対向配置させた状態にするものである。すなわち、磁力発生ヨ ーク部22の中心位置と第2の摺動ヨーク部48の中心位置とが重なり合う状態 となり、このとき、第2の摺動ヨーク部70の磁性部材72a〜72fおよび非 磁性部材74a〜74eは、磁力発生ヨーク部22の磁性部材32a〜32fお よび非磁性部材30a〜30eに対して、平面的に見て、格子状に配置される。In the holder 10 shown in FIG. 6, when the object W is magnetically attracted and held on the upper surface of the fixed yoke portion 60, for example, as shown in FIG. 1 and FIG. It has the same function and effect as the embodiment shown in FIGS. In the holder 10 shown in FIG. 6, when the object W is detached from the upper surface of the fixed yoke portion 60, as shown in FIGS. 6 and 7, the operating portions 38a and 38b of the sliding plate 34 are moved. By operation, the second sliding yoke portion 70 is placed in a state of being opposed to the upper surface of the magnetic force generating yoke portion 22 of the base 12. That is, the center position of the magnetic force generating yoke portion 22 and the center position of the second sliding yoke portion 48 overlap each other. At this time, the magnetic members 72a to 72f and the non-magnetic The members 74a to 74e are arranged in a lattice shape with respect to the magnetic members 32a to 32f and the non-magnetic members 30a to 30e of the magnetic force generating yoke portion 22 when viewed in plan.
【0048】 この場合、磁力発生ヨーク部22の磁石体28a〜28eの各N極から出た磁 束は、特に、図7の2点鎖線で示すように、それぞれ、磁力発生ヨーク部22の 各磁性部材32a〜32fから、間隙部68を介して、第2の摺動ヨーク部70 の各磁性部材72a〜72fへ流れ、再び、間隙部68を介して、磁力発生ヨー ク部22の各磁性部材32a〜32fを通って、磁石体28a〜28e各S極へ 入る。そのため、磁力発生ヨーク部22で発生した磁力は、固定ヨーク部60の 上面には作用することがない。In this case, the magnetic flux emitted from each of the N poles of the magnet bodies 28 a to 28 e of the magnetic force generating yoke part 22 is, in particular, as shown by a two-dot chain line in FIG. From the magnetic members 32a to 32f, the gap flows through the gaps 68 to the respective magnetic members 72a to 72f of the second sliding yoke portion 70. The magnets 28a to 28e enter the respective south poles through the members 32a to 32f. Therefore, the magnetic force generated by the magnetic force generating yoke portion 22 does not act on the upper surface of the fixed yoke portion 60.
