可動体と支持体とを接続体によって接続するアクチュエータでは、支持体が外部からの力によって変形すると、接続体が変形して振動特性が変化してしまう。本願出願人は、特願２０１９－２２０１６２において、円筒形のアクチュエータを提案している。特願２０１９－２２０１６２のアクチュエータでは、支持体は、円筒形のケースと、ケースの両端を塞ぐ蓋部材と、ケースの内側に配置されるコイルホルダを備えており、可動体は、コイルホルダの内周側において軸線方向に振動する。 In an actuator in which a movable body and a supporting body are connected by a connecting body, when the supporting body is deformed by an external force, the connecting body is deformed and the vibration characteristics change. The applicant of this application has proposed a cylindrical actuator in Japanese Patent Application No. 2019-220162. In the actuator of Japanese Patent Application No. 2019-220162, the support body includes a cylindrical case, a lid member that closes both ends of the case, and a coil holder arranged inside the case, and the movable body is arranged inside the coil holder. It vibrates in the axial direction on the circumferential side.

特願２０１９－２２０１６２のアクチュエータでは、ケースにコイル線を外部へ引き出すための矩形の切欠き部が形成されている。蓋部材はケースの縁に係止されているが、接着剤や溶接により固定されてはいない。そのため、外部から支持体に荷重が加わったとき、切欠き部が拡がることを規制できず、支持体が変形してアクチュエータの特性が変化するおそれがある。 In the actuator of Japanese Patent Application No. 2019-220162, a rectangular notch is formed in the case to draw out the coil wire to the outside. The lid member is secured to the edge of the case, but is not fixed with adhesive or welding. Therefore, when a load is applied to the support from the outside, it is impossible to prevent the notch from expanding, which may deform the support and change the characteristics of the actuator.

以上の問題点に鑑みて、本発明の課題は、可動体と支持体とを接続体によって接続するアクチュエータにおいて、支持体の変形を抑制することにある。 In view of the above problems, an object of the present invention is to suppress deformation of a support in an actuator that connects a movable body and a support by a connecting body.

上記課題を解決するために、本発明に係るアクチュエータは、支持体と、可動体と、前記支持体および前記可動体に接続され、弾性および粘弾性の少なくとも一方を備えた接続体と、磁石およびコイルを備え、前記可動体を前記支持体に対して相対移動させる磁気駆動機構と、を有し、前記支持体は、前記可動体の外周側を囲む筒状のケースと、前記ケースの端部を塞ぐ蓋部材と、を備え、前記蓋部材は、前記ケースの縁を軸線方向に切り欠いた切欠き部に嵌まるカバーを備え、前記切欠き部の縁と前記カバーの縁との間に配線引き出し部が設けられ、前記カバーの周方向の両側の縁は、前記切欠き部の縁を係止する係止部を備えることを特徴とする。 In order to solve the above problems, an actuator according to the present invention includes a support body, a movable body, a connecting body connected to the support body and the movable body and having at least one of elasticity and viscoelasticity, a magnet and a magnetic drive mechanism that includes a coil and moves the movable body relative to the support body; the support body includes a cylindrical case surrounding the outer peripheral side of the movable body; and an end portion of the case; a lid member for closing the case, the lid member comprising a cover that fits into a notch cut out in the axial direction of the edge of the case, and a gap between the edge of the notch and the edge of the cover. A wire lead-out portion is provided, and both circumferential edges of the cover include locking portions that lock the edges of the notch.

本発明によれば、支持体を組み立てると、ケースを切り欠いた切欠き部の縁と切欠き部に嵌まるカバーの縁との間に配線引き出し部が形成されるとともに、カバーの周方向の両側の縁によって切欠き部の縁が係止される。従って、切欠き部の幅が拡がることを規制できるため、支持体の変形を抑制できる。よって、支持体の変形に起因する振動特性の変化を抑制できる。 According to the present invention, when the support is assembled, a wiring lead-out portion is formed between the edge of the notch cut out of the case and the edge of the cover that fits into the notch, and the wiring lead-out portion is formed in the circumferential direction of the cover. The edges of the notch are locked by the edges on both sides. Therefore, since it is possible to restrict the width of the notch from expanding, deformation of the support body can be suppressed. Therefore, changes in vibration characteristics caused by deformation of the support can be suppressed.

本発明において、前記切欠き部の周方向の両側の縁に前記軸線方向に延びる溝部が設けられ、前記係止部は、前記溝部に嵌まるリブであることが好ましい。このような係止構造を設けることで、切欠き部の幅が拡がることを規制できる。また、カバーを切欠き部に挿入する際に、同時に溝部にリブを挿入して切欠き部の縁を係止することができる。従って、ケースと蓋部材とを容易に組み立てることができる。 In the present invention, it is preferable that grooves extending in the axial direction are provided on both edges in the circumferential direction of the notch, and that the locking portion is a rib that fits into the groove. By providing such a locking structure, it is possible to restrict the width of the notch from increasing. Furthermore, when inserting the cover into the notch, the rib can be inserted into the groove at the same time to lock the edge of the notch. Therefore, the case and the lid member can be easily assembled.

本発明において、前記支持体は、前記切欠き部の内周側に配置されるコイルホルダを備える。このようにすると、切欠き部の縁が内周側へ変形することをコイルホルダによって規制できるため、支持体の変形を抑制できる。また、コイルホルダの外周面から引き出したコイル線や端子ピンを配線引き出し部に配置しやすい。 In the present invention, the support body includes a coil holder arranged on the inner peripheral side of the notch. In this way, the coil holder can prevent the edge of the notch from deforming inward, thereby suppressing deformation of the support. Further, it is easy to arrange the coil wires and terminal pins pulled out from the outer circumferential surface of the coil holder in the wiring pull-out portion.

本発明において、前記配線引き出し部は、前記切欠き部の縁に形成された保持溝を備え、前記コイルに接続されるコイル線もしくは端子ピンは、前記保持溝に配置されることが好ましい。このようにすると、コイル線や端子ピンを容易に位置決めできる。従って、コイル線や端子ピンを配線基板に容易に接続できる。 In the present invention, it is preferable that the wiring lead-out part includes a holding groove formed at the edge of the notch, and the coil wire or terminal pin connected to the coil is arranged in the holding groove. In this way, the coil wires and terminal pins can be easily positioned. Therefore, the coil wire and terminal pin can be easily connected to the wiring board.

本発明において、前記コイルと電気的に接続される配線基板を備え、前記ケースは、前記切欠き部に前記軸線方向で隣り合う基板固定部を備え、前記基板固定部は、前記配線基板の縁を係止する爪部を備えることが好ましい。このようにすると、配線基板を容易に固定できる。また、配線基板の縁を配線引き出し部に配置できるので、コイル線もしくは端子ピンと配線基板との接続が容易である。 In the present invention, the case includes a wiring board electrically connected to the coil, the case includes a board fixing part adjacent to the notch in the axial direction, and the board fixing part is arranged at an edge of the wiring board. It is preferable to include a claw portion for locking. In this way, the wiring board can be easily fixed. Furthermore, since the edge of the wiring board can be placed in the wiring lead-out portion, it is easy to connect the coil wire or terminal pin to the wiring board.

この場合に、前記爪部は、前記配線基板の前記軸線方向の一端および他端の２か所を係止することが好ましい。このようにすると、爪部のみで配線基板を固定することも可能であり、配線基板の固定が容易である。また、配線基板を軸線方向に位置決めできるので、配線引き出し部６０に対して配線基板を位置決めできる。従って、コイル線もしくは端子ピンと配線基板との接続が容易である。 In this case, it is preferable that the claw portion locks the wiring board at two locations, one end and the other end in the axial direction. In this way, it is possible to fix the wiring board only with the claw portions, and the wiring board can be easily fixed. Further, since the wiring board can be positioned in the axial direction, the wiring board can be positioned with respect to the wiring lead-out portion 60. Therefore, connection between the coil wire or the terminal pin and the wiring board is easy.

本発明において、前記配線基板は、前記基板固定部に接着される。このように、爪部と接着剤を併用することにより、配線基板の固定強度を高めることができる。 In the present invention, the wiring board is adhered to the board fixing part. In this way, by using the claw portion and adhesive together, the fixing strength of the wiring board can be increased.

本発明によれば、支持体は、配線引き出し部を設けるための切欠き部が形成されたケースと、切欠き部に嵌まるカバーを備えた蓋部材を有している。支持体を組み立てると、カバーの周方向の両側の縁によって切欠き部の縁が係止される。従って、切欠き部の幅が広がることを規制できるため、支持体の変形を抑制できる。よって、支持体の変形に起因する振動特性の変化を抑制できる。 According to the present invention, the support body includes a case in which a notch for providing a wiring lead-out portion is formed, and a lid member provided with a cover that fits into the notch. When the support is assembled, the edges of the notch are locked by the edges on both sides of the cover in the circumferential direction. Therefore, since it is possible to restrict the width of the notch from increasing, deformation of the support body can be suppressed. Therefore, changes in vibration characteristics caused by deformation of the support can be suppressed.

The through hole 76 is arranged between the land 74 and the winding part 75, so the lead wire 8 connected to the land 74 is passed through the through hole 76 and held between the land 74 and the winding part 75. be done. Thereby, when winding the lead wire 8 around the winding portion 75, it is possible to suppress the application of strong force to the soldered portion where the lead wire 8 is soldered to the land 74. By winding the lead wire 8 around the winding portion 75, when the lead wire 8 drawn out to the outside of the wiring board 7 is pulled, force is less likely to be transmitted to the soldered portion where the lead wire 8 is soldered to the land 74. .

第１接続体１１および第２接続体１２は、ゲル材料を成形したゲル状ダンパー部材であ
る。第１接続体１１を成形するにあたっては、治具によって第１環状部材５１および第１固定部材３６を同軸に位置決めして第１環状部材５１と第１固定部材３６との間に環状の隙間を形成し、この隙間にゲル材料を充填して熱硬化させる。これにより、ゲル状ダンパー部材自身の粘着性によって、第１接続体１１が第１環状部材５１の第１環状壁５１０、および、第１固定部材３６の外周面に接合される。なお、ゲル材料を充填する前に、第１環状部材５１の第１環状壁５１０、および第１固定部材３６の外周面にプライマーを塗布することによって、第１接続体１１と第１環状壁５１０との接合強度、および第１接続体１１と第１固定部材３６との接合強度を高めるようにしてもよい。上記プライマー以外に他の接合促進剤等を使用してもよく、別に成形したゲル状ダンパー部材を第１環状部材５１および第１固定部材３６に接着剤等で接着してもよい。第２接続体１２についても、同様に、第２環状部材５２と第２固定部材３７との間に環状の隙間を形成し、この隙間にゲル材料を充填して熱硬化させることにより成形される。これにより、ゲル状ダンパー部材自身の粘着性によって、第２接続体１２が第２環状部材５２の第２環状壁５２０、および、第２固定部材３７の外周面に接合される。 The first connecting body 11 and the second connecting body 12 are gel-like damper members made of gel material. In forming the first connecting body 11, the first annular member 51 and the first fixing member 36 are coaxially positioned using a jig to form an annular gap between the first annular member 51 and the first fixing member 36. This gap is then filled with a gel material and cured by heat. Thereby, the first connecting body 11 is joined to the first annular wall 510 of the first annular member 51 and the outer peripheral surface of the first fixing member 36 due to the adhesiveness of the gel-like damper member itself. Note that before filling the gel material, by applying a primer to the first annular wall 510 of the first annular member 51 and the outer peripheral surface of the first fixing member 36, the first connecting body 11 and the first annular wall 510 are The bonding strength between the first connecting body 11 and the first fixing member 36 may be increased. In addition to the primer described above, other adhesion promoters may be used, and a separately molded gel-like damper member may be bonded to the first annular member 51 and the first fixing member 36 with an adhesive or the like. Similarly, the second connecting body 12 is formed by forming an annular gap between the second annular member 52 and the second fixing member 37, filling this gap with gel material, and thermosetting the gel material. . Thereby, the second connecting body 12 is joined to the second annular wall 520 of the second annular member 52 and the outer peripheral surface of the second fixing member 37 due to the adhesiveness of the gel-like damper member itself.

このように、本形態では、アクチュエータ１を組み立てる際には、予め、第１環状部材５１と第１固定部材３６とを第１接続体１１によって接続した部品を製造しておく。また、第２環状部材５２と第２固定部材３７とを第２接続体１２によって接続した部品を製造しておく。そして、支持体２を組み立てる際に、第１環状部材５１をコイルホルダ４に圧入することによってコイルホルダ４に固定し、コイルホルダ４をケース２０に圧入することによってケース２０に固定する。一方、可動体３を組み立てる際に、支軸３０に第１固定部材３６を固定する。これにより、ゲル状ダンパー部材を接着する工程を行わずに、第１接続体１１によって支持体２と可動体３とを接続することができる。同様に、支持体２を組み立てる際に、第２環状部材５２をケース２０の環状部２５に圧入することによってケース２０に固定する。一方、可動体３を組み立てる際に、支軸３０に第２固定部材３７を固定する。これにより、ゲル状ダンパー部材を接着する工程を行わずに、第２接続体１２によって支持体２と可動体３とを接続することができる。 In this manner, in this embodiment, when assembling the actuator 1, a component in which the first annular member 51 and the first fixing member 36 are connected by the first connecting body 11 is manufactured in advance. Further, a component in which the second annular member 52 and the second fixing member 37 are connected by the second connecting body 12 is manufactured in advance. When assembling the support body 2, the first annular member 51 is fixed to the coil holder 4 by being press-fitted into the coil holder 4, and the coil holder 4 is fixed to the case 20 by being press-fitted into the case 20. On the other hand, when assembling the movable body 3, the first fixing member 36 is fixed to the support shaft 30. Thereby, the support body 2 and the movable body 3 can be connected by the first connection body 11 without performing the process of bonding the gel-like damper member. Similarly, when assembling the support body 2, the second annular member 52 is fixed to the case 20 by being press-fitted into the annular portion 25 of the case 20. On the other hand, when assembling the movable body 3, the second fixing member 37 is fixed to the support shaft 30.

本形態において、第１接続体１１および第２接続体１２は粘弾性部材である。粘弾性とは、粘性と弾性の両方を合わせた性質のことであり、プラスチックやゴム等の高分子物質に顕著に見られる性質である。従って、第１接続体１１および第２接続体１２として、シリコーンゲル等からなるゲル状部材、天然ゴム、ジエン系ゴム（例えば、スチレン・ブタジエンゴム、イソプレンゴム、ブタジエンゴム、クロロプレンゴム、アクリロニトリル・ブタジエンゴム等）、非ジエン系ゴム（例えば、ブチルゴム、エチレン・プロピレンゴム、エチレン・プロピレン・ジエンゴム、ウレタンゴム、シリコーンゴム、フッ素ゴム等）、熱可塑性エラストマー等の各種ゴム材料及びそれらの変性材料を用いることができる。本形態において、第１接続体１１および第２接続体１２は、シリコーンゲル等からなるゲル状ダンパー部材である。 In this embodiment, the first connecting body 11 and the second connecting body 12 are viscoelastic members. Viscoelasticity is a property that combines both viscosity and elasticity, and is a property that is prominently seen in polymeric substances such as plastics and rubber. Therefore, as the first connecting body 11 and the second connecting body 12, a gel-like member made of silicone gel or the like, natural rubber, diene rubber (for example, styrene-butadiene rubber, isoprene rubber, butadiene rubber, chloroprene rubber, acrylonitrile-butadiene rubber, rubber, etc.), non-diene rubbers (e.g., butyl rubber, ethylene/propylene rubber, ethylene/propylene/diene rubber, urethane rubber, silicone rubber, fluororubber, etc.), thermoplastic elastomers, and other rubber materials and modified materials thereof. be able to. In this embodiment, the first connecting body 11 and the second connecting body 12 are gel-like damper members made of silicone gel or the like.

（アクチュエータの動作）
アクチュエータ１は、コイル６２に通電することにより、磁気駆動機構６が、可動体３を軸線Ｌ方向に駆動する駆動力を発生させる。コイル６２への通電を切ると、可動体３は、接続体１０の復帰力によって原点位置へ戻る。従って、コイル６２への通電を断続的に行うことにより、可動体３は、軸線Ｌ方向で振動する。また、コイル６２に印加する交流波形を調整することで、可動体３が軸線Ｌ方向の一方側Ｌ１に移動する加速度と、可動体３が軸線Ｌ方向の他方側Ｌ２に移動する加速度を異なるものとすることができる。それ故、アクチュエータ１を触覚デバイスとして取り付けた機器を手にした者は、軸線Ｌ方向において方向性を有する振動を体感することができる。また、アクチュエータ１を利用してスピーカを構成することもできる。 (Actuator operation)
In the actuator 1, by energizing the coil 62, the magnetic drive mechanism 6 generates a driving force that drives the movable body 3 in the axis L direction. When the coil 62 is de-energized, the movable body 3 returns to its original position by the return force of the connecting body 10. Therefore, by intermittently energizing the coil 62, the movable body 3 vibrates in the direction of the axis L. Furthermore, by adjusting the AC waveform applied to the coil 62, the acceleration at which the movable body 3 moves to one side L1 in the direction of the axis L and the acceleration at which the movable body 3 moves to the other side L2 in the direction of the axis L can be made different. It can be done. Therefore, a person who holds a device to which the actuator 1 is attached as a tactile device can experience vibrations having directionality in the direction of the axis L. Furthermore, the actuator 1 can also be used to configure a speaker.

また、可動体３が支持体２に対して軸線Ｌ方向に振動する際、第１接続体１１および第２接続体１２は、可動体３の振動に追従してせん断方向に変形する。ここで、シリコーンゲル等のゲル状ダンパー部材は、その伸縮方向によって、線形あるいは非線形の伸縮特性を備える。例えば、ゲル状ダンパー部材は、その厚さ方向に押圧されて圧縮変形する際は、線形の成分よりも非線形の成分が大きい伸縮特性を備える一方、厚さ方向に引っ張られて伸びる場合は、非線形の成分よりも線形の成分が大きい伸縮特性を備える。また、厚さ方向と交差する周方向または軸線Ｌ方向（せん断方向）に変形する場合も、非線形の成分よりも線形の成分が大きい変形特性を持つ。本形態においては、可動体３が振動した際、第１接続体１１および第２接続体１２（ゲル状ダンパー部材）は、可動体３の振動に追従してせん断方向に変形する。従って、第１接続体１１および第２接続体１２は、線形性が高い範囲で変形するので、リニアリティが良好な振動特性を得ることができる。 Further, when the movable body 3 vibrates in the direction of the axis L relative to the support body 2, the first connecting body 11 and the second connecting body 12 deform in the shearing direction following the vibration of the movable body 3. Here, a gel-like damper member such as silicone gel has linear or non-linear expansion and contraction characteristics depending on the direction of expansion and contraction. For example, when a gel-like damper member is compressed and deformed by being pressed in the thickness direction, the nonlinear component is larger than the linear component, but when it is stretched by being pulled in the thickness direction, it has a nonlinear It has an elastic property in which the linear component is larger than the component. Furthermore, when deforming in the circumferential direction or the axis L direction (shear direction) that intersects the thickness direction, the deformation characteristic is such that the linear component is larger than the nonlinear component. In this embodiment, when the movable body 3 vibrates, the first connecting body 11 and the second connecting body 12 (gel-like damper members) follow the vibration of the movable body 3 and deform in the shearing direction. Therefore, the first connecting body 11 and the second connecting body 12 are deformed within a range with high linearity, so that vibration characteristics with good linearity can be obtained.

なお、可動体３が径方向に移動する場合には、第１接続体１１および第２接続体１２が潰れる方向に変形する。ここで、ゲル状部材が潰れる方向に変形する場合のバネ定数は、ゲル状部材がせん断方向に変形する場合のバネ定数の３倍程度である。このため、可動体３が振動方向（軸線Ｌ方向）とは異なる方向に移動することを抑制できる。よって、可動体３が意図しない方向へ動くことを抑制でき、可動体３と支持体２との衝突を抑制できる。 Note that when the movable body 3 moves in the radial direction, the first connecting body 11 and the second connecting body 12 are deformed in a direction in which they are crushed. Here, the spring constant when the gel-like member is deformed in the crushing direction is about three times the spring constant when the gel-like member is deformed in the shearing direction. Therefore, it is possible to suppress the movable body 3 from moving in a direction different from the vibration direction (axis L direction). Therefore, the movable body 3 can be prevented from moving in an unintended direction, and the collision between the movable body 3 and the support body 2 can be suppressed.

As described above, the actuator 1 of the present embodiment includes a support 2, a movable body 3, a connecting body 10 connected to the support 2 and the movable body 3 and having at least one of elasticity and viscoelasticity, and a magnet. 61 and a coil 62, and a magnetic drive mechanism 6 that moves the movable body 3 relative to the support body 2. The support body 2 includes a cylindrical case 20 that surrounds the outer peripheral side of the movable body 3 and a first lid member 21 (lid member) that closes an end of the case 20. A cover 66 is provided that fits into a notch 65 formed by cutting out the edge of the cover in the direction of the axis L. A wiring lead-out portion 60 is provided between the edge of the notch portion 65 and the edge of the cover 66, and both circumferential edges of the cover 66 are provided with locking portions 68 that lock the edges of the notch portion 65. .

このように、本形態では、支持体２を組み立てると、ケース２０を切り欠いた切欠き部６５の縁と切欠き部６５に嵌まるカバー６６の縁との間に配線引き出し部６０が形成されるとともに、カバー６６の周方向の両側の縁によって切欠き部６５の縁が係止される。従って、切欠き部６５の幅が拡がることを規制できるため、支持体２の変形を抑制できる。よって、支持体２の変形に起因する振動特性の変化を抑制できる。 In this manner, in this embodiment, when the support body 2 is assembled, the wiring lead-out portion 60 is formed between the edge of the notch portion 65 cut out in the case 20 and the edge of the cover 66 that fits into the notch portion 65. At the same time, the edges of the notch 65 are locked by the edges on both sides of the cover 66 in the circumferential direction. Therefore, since it is possible to restrict the width of the notch portion 65 from expanding, deformation of the support body 2 can be suppressed. Therefore, changes in vibration characteristics caused by deformation of the support body 2 can be suppressed.

本形態では、切欠き部６５の周方向の両側の縁に軸線Ｌ方向に延びる溝部６７が設けられ、係止部６８は、溝部６７に嵌まるリブである。このような係止構造を設けることにより、切欠き部６５の幅が拡がることを規制できる。また、カバー６６を切欠き部６５に挿入する際に、同時に溝部６７にリブ（係止部６８）を挿入して切欠き部６５の縁を係止できる。従って、ケース２０と第１蓋部材２１とを容易に組み立てることができる。 In this embodiment, grooves 67 extending in the direction of the axis L are provided on both edges of the notch 65 in the circumferential direction, and the locking portions 68 are ribs that fit into the grooves 67 . By providing such a locking structure, it is possible to restrict the width of the cutout portion 65 from expanding. Furthermore, when inserting the cover 66 into the notch 65, a rib (locking part 68) can be inserted into the groove 67 at the same time to lock the edge of the notch 65. Therefore, the case 20 and the first lid member 21 can be easily assembled.

本形態の支持体２は、切欠き部６５の内周側に配置されるコイルホルダ４を備えるため、切欠き部６５の縁が内周側へ変形することをコイルホルダ４によって規制でき。従って、支持体２の変形を抑制できる。また、コイルホルダ４の外周面から引き出したコイル線６３や端子ピン６４を配線引き出し部６０に配置しやすい。 Since the support body 2 of this embodiment includes the coil holder 4 disposed on the inner circumferential side of the notch portion 65, the coil holder 4 can prevent the edge of the notch portion 65 from deforming toward the inner circumferential side. Therefore, deformation of the support body 2 can be suppressed. Further, the coil wire 63 and the terminal pin 64 drawn out from the outer circumferential surface of the coil holder 4 can be easily arranged in the wiring drawing part 60.

本形態の配線引き出し部６０は、切欠き部６５の縁に形成された保持溝７１を備えるため、コイル６２に接続されるコイル線６３もしくは端子ピン６４を保持溝７１に配置できる。従って、コイル線６３もしくは端子ピン６４を容易に位置決めできるので、コイル線６３もしくは端子ピン６４を配線基板７に容易に接続できる。 Since the wiring lead-out portion 60 of this embodiment includes the holding groove 71 formed at the edge of the notch portion 65, the coil wire 63 or the terminal pin 64 connected to the coil 62 can be placed in the holding groove 71. Therefore, since the coil wire 63 or the terminal pin 64 can be easily positioned, the coil wire 63 or the terminal pin 64 can be easily connected to the wiring board 7.

本形態のケース２０は、切欠き部６５に軸線Ｌ方向で隣り合う基板固定部６９を備え、基板固定部６９は、コイル６２と電気的に接続される配線基板７の縁を係止する爪部６９１を備える。このようにすると、配線基板７を容易に固定できる。また、配線基板７の縁を配線引き出し部６０に配置できるので、コイル線６３もしくは端子ピン６４と配線基板７との接続が容易である。 The case 20 of this embodiment includes a board fixing part 69 adjacent to the notch part 65 in the direction of the axis L, and the board fixing part 69 has a claw that locks the edge of the wiring board 7 that is electrically connected to the coil 62. 691. In this way, the wiring board 7 can be easily fixed. Further, since the edge of the wiring board 7 can be arranged in the wiring lead-out portion 60, the connection between the coil wire 63 or the terminal pin 64 and the wiring board 7 is easy.

例えば、本形態では、爪部６９１は、配線基板７の軸線Ｌ方向の一端および他端の２か所を係止するため、配線基板７を軸線Ｌ方向に位置決めでき、配線引き出し部６０に対して配線基板７を位置決めできる。従って、コイル線６３もしくは端子ピン６４と配線基板７との接続が容易である。 For example, in this embodiment, the claw portion 691 locks two places, one end and the other end of the wiring board 7 in the direction of the axis L, so that the wiring board 7 can be positioned in the direction of the axis L, and The wiring board 7 can be positioned by Therefore, connection between the coil wire 63 or the terminal pin 64 and the wiring board 7 is easy.

本形態では、配線基板７は、基板固定部６９に接着されており、爪部６９１と接着剤を併用して固定される。従って、配線基板７の固定強度が高い。なお、接着剤を使用せずに、爪部６９１のみで配線基板７を固定する構造を採用してもよい。この場合には、配線基板７を容易に固定できる。 In this embodiment, the wiring board 7 is adhered to the board fixing part 69, and is fixed using a combination of the claw parts 691 and an adhesive. Therefore, the fixing strength of the wiring board 7 is high. Note that a structure may be adopted in which the wiring board 7 is fixed only by the claw portions 691 without using adhesive. In this case, the wiring board 7 can be easily fixed.
