Description

【考案の詳細な説明】【０００１】【産業状の利用分野】本考案はパチンコ機の打球発射装置の操作ダイヤルに関するものである。【０００２】【従来技術とその問題点】従来、パチンコ機の操作ダイヤルとしては、カップ状の前方握手部材とカップ状の後方握手部材とを互いに向き合せ、それらから突出しているガイドボスによって両握手部材を互いに装着可能とする一方、両握手部材の間に同軸的に円板状の操作レバーを配置し、該操作レバーには、その回転中心軸から一定の半径の所に円弧状のスリットを設け、このスリットに上記ガイドボスを貫通せしめることにより、両握手部材に対し操作レバーを回転操作可能にした構成のものが知られている。この場合、操作ダイヤル内には、操作レバーを原位置に復帰させるための復帰コイルバネが装置される。【０００３】従来の操作ダイヤルでは、比較的径の大きな渦巻バネが操作ダイヤルと同軸的に設けられていた。即ち、前方握手部材と操作レバーとの間に、比較的大きな渦巻バネを操作ダイヤルと同軸的に挿入し、その一端を操作レバーの穴に、他端を前方握手部材の穴に差し込むように引っ掛ける構造であった。このような構造では、使用する渦巻バネの径が操作ダイヤルの径に達する大きさとせざるを得ないし、操作ダイヤルを組み立てる際には、一方で渦巻バネをその大きな反発力に抗して強い方で圧縮しつつ、他方で前方握手部材のガイドボスを操作レバーのスロット内に通し、且つ、このガイドボスを後方握手部材と結合しなければならず、この点で組立作業がやりにくく、作業性に問題があった。又、渦巻バネの力は一般に伸縮のストロークが短く、渦巻の径が大きくなる程強くなるため、操作レバーの回動量が大きくなるにしたがってその反発力が急激に大きくなり、遊技者にとっては操作性が悪く違和感があって、疲れ易いものであった。本考案は、上記欠点のない操作ダイヤルの提供を目的とするものである。【０００４】【問題を解決する手段】本考案は、操作レバーを挟んで前方握手部材と後方握手部材との両握手部材を互いに向き合せ、両握手部材又はその一方め握手部材側から突出させたガイドボスによって両握手部材を互いに装着可能とし、操作レバーにはその回転中心軸から一定の半径の所に円弧状のスリットを設け、該スリットに上記ガイドボスを貫通せしめて両握手部材を固定することにより操作レバーを回転操作可能にしたパチンコ機の操作ダイヤルに於て、前記操作レバーの前方握手部材側と対向する面には第１のバネ係止部を、後方握手部材内には第２のバネ係止部を各々設け、該第２のバネ係止部は操作レバーの上記スリットを貫通して操作レバーの前方握手部材側に臨ませ、第１のバネ係止部と第２のバネ係止部との間に復帰コイルバネを掛け止めて引っ張りバネとして機能せしめ、操作レバーの前方握手部材側と対向する面には、この復帰コイルバネを操作レバーの回動方向に沿って弧状に伸縮させるための弧状ガイド部を設けた構成としたものである。【０００５】【実施例】第１図に於て、本考案の操作ダイヤル１（第４図参照）は、カップ状の後方握手部材１０と、操作レバー２０と、該操作レバー２０を挟んで後方握手部材１０に向き合せたカップ状の前方握手部材３０とから成る。後方及び前方の両握手部材１０、３０は、ほぼ同じ外形で、この実施例では空胴の円筒を２つ割りした形となっている。又、操作レバー２０もほぼ同形の円板状をしており周辺に指掛部２０Ａ、２０Ｂを有する。後方握手部材１０は、その後端面より突出させた小径の保持部１１を有し、該保持部１１の端面は、第４図に示すように、パチンコ機の前面枠２を貫通し、取付基板３にネジ止めされる。この保持部１１は完全な円筒状とせず、例えば断面半月状に形成し、その平坦部によって前面枠２に強固に止着するのが好ましい。後方握手部材１０の内部の底面１２には、その中央に、円筒形ホルダー１３が設けてあり、該ホルダー１３内には、可変抵抗器１４の円筒ケース部１４Ａが収納されている。又、当該底面１２には、可変抵抗器１４からのリード線を引き出すための貫通孔１２Ａが設けてある。図中の符号１５は、可変抵抗器１４がホルダー１３に対し回転したり離脱したりしないようにするための固定部材であり、コの字形にくぼんだ押え部１５Ｃと、取付用の外向フランジ１５Ａ、１５Ｂとを有する。押え部１５Ｃの長さは、可変抵抗器１４の長方形の端子板１４Ｃが嵌り込む長さになっている。【０００６】可変抵抗器１４は、押え部１５Ｃに設けた穴１６に可変抵抗器１４の回動軸部１４Ｂを通し、外向フランジ１５Ａ、１５Ｂを、後方握手部材１０の内部底面１２に設けた取付ボス１７に取付けることにより、第２図の如く後方握手部材１０内に取付けられる。可変抵抗器１４の回動軸部１４Ｂは、穴１６から出て後方握手部材１０の外まで長く突出し、且つ、この突出した部分は断面半円状に形成されていて、この部分には断面が多角形の係合部分１８Ａを有する連結部材１８が差し込まれている。この実施例では係合部分１８Ａは正方形断面としてある。操作レバー２０の中央には、係合部分１８Ａと相補形状の連結孔２１が設けてあり、該連結孔２１は連結部材１８の係合部分１８Ａに嵌め込まれている。従って、操作レバー２０を回すと、可変抵抗器１４の回動軸部１４Ｂが回る。【０００７】操作レバー２０には、その回動中心から一定の半径の所に、２つの円弧状のスリット２２、２３が直径方向に対向して設けてある。後方握手部材１０の内部底面１２には、ホルダー１３の周囲の領域に、一対のガイドボス１９Ａ、１９Ｂが２組互いに直径方向に対向して設けられており、一方、前方握手部材３０の内部底面にも、これらのガイドボス１９Ａ、１９Ｂと対応するガイドボス（図示せず）が設けられている。この前方握手部材３０のガイドボスは、操作レバー２０に設けた２つの円弧状スリット２２、２３を通って、後方握手部材１０内のガイドボス１９Ａ、１９Ｂに当接しており、後方握手部材１０の保持部１１側からガイドボス内に差し込まれたネジ（図示せず）により、後方握手部材１０に固定されている。【０００８】この場合、後方及び前方の両握手部材１０、３０のガイドボスの長さは、両ガイドボスを互いに連結したとき、後方及び前方の両握手部材１０、３０の間に、丁度、操作レバー２０の厚みに相当する間隙が残るように定めてある。この間隙内に位置する操作レバー２０は、その前方握手部材側と対向する面に、連結孔２１を取囲む円環２４を有しており、該円環２４は後述する復帰コイルバネ２７の胴体部を操作レバー２０の回動方向に沿って同心円状に曲げて延在させる弧状ガイド部として機能する。更に、この操作レバー２０の前方握手部材側と対向する面には、円環２４と一方のスリット２２との間の領域に、復帰コイルバネ２７の一端を止めるための第１のバネ係止部２５がピンの形に突設してある。【０００９】他方、復帰コイルバネ２７の他端を止めるための第２のバネ係止部２６は、後方握手部材１０内の底面１２にピンの形に突出してある。この第２のバネ係止部２６は、他方のスリット２３に属するガイドボス１９Ａ、１９Ｂの付近、正確にはスリット２３の幅内に設けてあり、スリット２３を貫通して操作レバー２０の前方握手部材側と対向する面に臨ませている。実施例の第１、第２のバネ係止部２５、２６は、弧状ガイド部材としての円環２４のほぼ両側に離れて突設されており、第１のバネ係止部２５と第２のバネ係止部２６との間に前記復帰コイルバネ２７が掛けられている。この場合、復帰コイルバネ２７は引っ張りバネとして機能しており、可変抵抗器１４の回動軸部１４Ｂが原位置に在る場合でも、第３図に示すように、復帰コイルバネ２７の胴体部が弧状ガイド部材たる円環２４の外周面に摺接しつつ操作レバー２０の回動方向と同心円状に曲げ延ばされた形に延在して、操作レバー２０に対し第３図で時計方向の回動習性を与えている。【００１０】図示の例では、円環２４の端面には鍔２４Ａを設け、操作レバーの回転時に、この復帰コイルバネ２７が円環２４の外周面から外れないようにしてある。尚、後方握手部材１０内には、単発打ちボタン２８を押したとき作動して、打球発射装置を停止させるマイクロスイッチ２９が設けてある。又、前方握手部材３０の端面の中央には、円形のレンズ部材３１が嵌込まれている。従来の如く、渦巻コイルバネを、操作レバー２０と前方握手部材３０とに係止させる構成では、前方握手部材３０を取付ける際、渦巻コイルバネを圧縮しつつ取付けることになる。これに対して本考案では、コイルバネを復帰バネとして採用して、操作レバー２０の片面に臨ませた第１のバネ係止部２５と第２のバネ係止部２６との間に掛けわたされており、前方握手部材３０とは係合させていないので、前方握手部材３０は、組立の最終段階に於て復帰バネの作用を受けることなく極めて簡単に取付けることができる。又、従来では、渦巻バネの作用点が、操作レバー２０の面とその面から離れた地点とにあるため、バネの復帰力が操作レバー２０の回動方向に対して斜めにズレて作用することになる。【００１１】これに対して本考案では、操作レバー２０の回動方向に対して平行に同方向に作用することになるから、操作レバー２０自体や可変抵抗器１４の回動軸部１４Ｂ等に無理な力がかからず、操作の際に違和感がなく円滑性が向上する。又、従来のように渦巻バネをひねる形式の場合には、渦巻バネの半径が比較的大きくならざるを得ず、これをセットする場合には比較的大きな力を必要とする。これに対して本考案ではコイルバネを引っ張りバネとして機能させているため、小径のバネでよく、その分だけ操作レバーを回動させる力が少なくて済み、且つ、バネの伸縮ストロークが長くなるため、操作レバー２０の回動量が大きくなっても、小さな力で操作レバー２０を楽に円滑に回動させることができる。従って又、長時間の遊戯による手首や指の疲労も軽減できる。【００１２】第４図において、前面枠２の下部分には、打球発射装置のロータリーソレノイド４が嵌込まれている。このロータリーソレノイド４又は前面枠２の裏面に固定した取付基板３に取付けられ、ロータリーソレノイド４の出力軸４’は取付基板３を貫通して裏側に突出しており、その先端部には発射杵５の基部が固定してある。発射杵５は、バネ６によって、第４図でみて常時反時計方向の回動習性を与えられており、ロータリーソレノイド４の非通電時には、第４図に示す如く、発射レール７から最も離れた待機位置にある。図中の符号８、９はこの発射杵５の待機位置及び弾発位置を規制するストッパである。発射杵５の動きを円滑にするため、ストッパ８は回動型として、また、ストッパ９は弾性部材により構成されている。【００１３】今、操作レバー２０を遊技者から見て時計方向に回動させると、可変抵抗器１４の回動軸部１４Ｂが回転され、その抵抗値が変化する。この抵抗値４は図示してない制御ユニットに伝達され、制御ユニットは、ロータリーソレノイド４をこの抵抗値に応じた電磁力で間欠的に付勢せしめる。即ち、この抵抗値に応じた電磁力により、発射杵５が、その都度バネ６に抗して、第４図で時計方向に回動する。この１回の回動毎に、発射杵５の杵先５Ａが発射レール基部７Ａの球を打撃し、打球は発射レール７を通って、遊技盤の遊技領域内に打ち込まれる。【００１４】【考案の効果】以上述べたように、本考案の操作ダイヤルは、操作レバーの前方握手部材側と対向する面に第１のバネ係止部を、後方握手部材に第２のバネ係止部を各々設け、この第２のバネ係止部は操作レバーの上記スリットを貫通して操作レバーの前方握手部材側に臨ませ、この第１のバネ係止部と第２のバネ係止部との間に復帰バネとしてのコイルバネを掛けわたして、当該コイルバネの伸縮性に富むコイルの軸方向の弾発力を引張バネとして機能せしめ、操作レバーの前方握手部材側と対向する面には、この復帰コイルバネを操作レバーの回動方向に沿って弧状に伸縮させるための弧状ガイド部を設けたものである。従って、後方握手部材と操作レバーとを組んだ状態で、復帰コイルバネをガイド部に沿って後方握手部材と操作レバーのバネ係止部材に止めることが可能となり、従来に較べて組立作業が容易となる。【００１５】又、本考案では、復帰コイルバネは操作レバーの回動操作方向に沿って伸縮性に富むコイルの軸方向に弾発力が作用するから、従来の渦巻コイルバネの巻回方向の弾発力と異なり、操作レバー自体やこれに連結される被操作部材、例えば可変抵抗器の回動軸部等に無理な力がかからず、円滑な操作が可能となるばかりか耐久性を増すことができる。又、復帰コイルバネは伸縮性に富むコイルの軸方向の弾発力が活用されているから、小径のコイルバネで十分であり、その分だけ操作レバーを回動させる力が小さくて済む。しかも、従来の渦巻バネに較べると、バネの伸縮ストロークを長くとることができるため、操作レバーの回動量が大きくなっても、小さな力で操作レバーを楽に円滑に回動させることができる。従って又、長時間の遊戯による手首や指の疲労も軽減できる。[Detailed description of the device] [0001] [Industrial use field] The present invention relates to an operation dial of a ball striking device for a pachinko machine. [0002] [Prior art and its problems] Conventionally, the operation dial of a pachinko machine has been a cup-shaped front handshake member and a cup. -Shaped rear handshake members face each other and the guide bosses projecting from them So that both handshake members can be attached to each other, while the two handshake members are coaxially disk-shaped. The operating lever is located at a certain radius from the center axis of rotation of the operating lever. Provide an arcuate slit in the and insert the guide boss into this slit. It is known that the operating lever can be rotated with respect to both handshake members. ing. In this case, in order to return the operation lever to its original position inside the operation dial. The return coil spring is installed. [0003] In the conventional operation dial, a spiral spring with a relatively large diameter is coaxial with the operation dial. Was installed in. That is, a comparatively large spiral spring is provided between the front handshake member and the operation lever. Coaxially with the lever, one end for the hole of the operating lever and the other end for the hole of the front handshake member. It was a structure that hooks like inserting. In such a structure, the diameter of the spiral spring used reaches the diameter of the operation dial. When assembling the operation dial, the spiral spring should be The boss of the front handshake member is compressed while the strong one compresses against the large repulsive force of the other. Through the slot of the operating lever and connect this guide boss with the rear handshake member. In this respect, the assembling work is difficult to perform and there is a problem in workability. In addition, the force of the spiral spring generally has a short expansion / contraction stroke, and the larger the spiral diameter, Since it becomes stronger, the repulsive force increases sharply as the amount of rotation of the operating lever increases. It becomes big, it is uncomfortable for the player, it feels strange, and it is easy to get tired. there were. The present invention aims to provide an operation dial that does not have the above-mentioned drawbacks. [0004] [Means for solving problems] The present invention has both the front handshake member and the rear handshake member sandwiching the operation lever. Guide arms that face each other and project from both handshake members or their first handshake member side Both handshake members can be attached to each other by the Arc-shaped slit at a certain radius from the above, and penetrate the guide boss into the slit. By inserting both hands and fixing both handshake members, the operation lever can be rotated. On the operation dial of the Chinko machine, A first spring locking portion is provided on the surface of the operation lever facing the front handshake member side, and Each of the second spring locking portions is provided in the hand member, and the second spring locking portion of the operation lever is provided. Penetrate through the slit and face the front handshake member side of the operating lever to lock the first spring. As a tension spring, a return coil spring is hooked between the spring section and the second spring locking section. This return coil bar is provided on the surface facing the front handshake member side of the operating lever. Provided with an arc-shaped guide portion for expanding and contracting the tool in an arc shape along the turning direction of the operation lever. It has a different configuration. [0005] 【Example】 Referring to FIG. 1, the operation dial 1 (see FIG. 4) of the present invention is a cup-shaped rear grip. The hand member 10, the operation lever 20, and the rear handshake member 10 with the operation lever 20 interposed therebetween. And a cup-shaped front handshake member 30 facing each other. Both the rear and front handshake members 10 and 30 have substantially the same outer shape, and are empty in this embodiment. It has a shape that divides the body cylinder into two. The operating lever 20 also has a disk shape of almost the same shape, and the finger hooks 20A and 20B are provided on the periphery. Have. The rear handshake member 10 has a small-diameter holding portion 11 protruding from the rear end surface thereof. As shown in FIG. 4, the end surface of the holding portion 11 penetrates through the front frame 2 of the pachinko machine and is removed. It is screwed to the attached substrate 3. The holding portion 11 is not formed into a perfect cylindrical shape, but is formed, for example, in a half-moon shape in cross section, It is preferable that the front frame 2 is firmly fixed to the front frame 2. A cylindrical holder 13 is provided at the center of the bottom surface 12 inside the rear handshake member 10. A cylindrical case portion 14A of the variable resistor 14 is housed in the holder 13. Has been paid. In addition, the bottom surface 12 has a through hole for drawing out the lead wire from the variable resistor 14. 12A is provided. Reference numeral 15 in the drawing indicates that the variable resistor 14 is rotated or separated from the holder 13. It is a fixing member to prevent the , And mounting outward flanges 15A and 15B. The length of the pressing portion 15C is the length into which the rectangular terminal plate 14C of the variable resistor 14 is fitted. It has become. [0006] The variable resistor 14 has a rotating shaft portion of the variable resistor 14 in a hole 16 provided in the holding portion 15C. 14B, and the outward flanges 15A and 15B to the inner bottom surface 1 of the rear handshake member 10. As shown in FIG. 2, the rear handshake member 10 can be mounted by attaching to the mounting boss 17 provided in FIG. Mounted inside. The rotary shaft portion 14B of the variable resistor 14 extends from the hole 16 to the outside of the rear handshake member 10. It has a long protrusion, and this protrusion has a semicircular cross section. A connecting member 18 having an engaging portion 18A having a polygonal cross section is inserted into It In this embodiment, the engaging portion 18A has a square cross section. A connecting hole 21 having a shape complementary to the engaging portion 18A is provided in the center of the operating lever 20. The connecting hole 21 is fitted in the engaging portion 18A of the connecting member 18. Therefore, when the operation lever 20 is turned, the turning shaft portion 14B of the variable resistor 14 turns. [0007] The operating lever 20 has two arc-shaped spaces at a certain radius from the center of rotation. Lits 22 and 23 are provided to face each other in the diametrical direction. On the inner bottom surface 12 of the rear handshake member 10, in the area around the holder 13, a pair of Two sets of guide bosses 19A and 19B are provided to face each other in the diametrical direction. On the other hand, on the inner bottom surface of the front handshake member 30, the guide bosses 19A and 19B are paired. A corresponding guide boss (not shown) is provided. This front handshake member 30 The id boss passes through the two arcuate slits 22 and 23 provided on the operation lever 20. , The rear handshake member 10 is in contact with the guide bosses 19A and 19B in the rear handshake member 10. With a screw (not shown) inserted into the guide boss from the holding portion 11 side of the material 10. It is fixed to the rear handshake member 10. [0008] In this case, the lengths of the guide bosses of the rear and front handshake members 10 and 30 are both When the id bosses are connected to each other, between the rear and front handshake members 10 and 30, It is set so that a gap corresponding to the thickness of the operating lever 20 remains. The operation lever 20 located in this gap is provided on the surface facing the front handshake member side. , A ring 24 surrounding the connecting hole 21. The ring 24 is a return coil described later. The body portion of the spring 27 is bent concentrically along the rotation direction of the operation lever 20 and extends. It functions as an arcuate guide part. Further, on the surface of the operating lever 20 facing the front handshake member side, a ring 24 and In the area between the first slit 22 and the second slit 22, a first coil for stopping one end of the return coil spring 27 is formed. The spring locking portion 25 of No. 1 is projected in the shape of a pin. [0009] On the other hand, the second spring locking portion 26 for stopping the other end of the return coil spring 27 is It projects in the shape of a pin on the bottom surface 12 inside the handshake member 10. The second spring locking portion 26 has a guide boss 19A belonging to the other slit 23, It is provided near 19B, to be precise within the width of the slit 23, and penetrates the slit 23. And faces the front handshake member side of the operating lever 20. The first and second spring locking portions 25 and 26 of the embodiment are annular rings as arc-shaped guide members. The first spring engaging portion 25 and the second spring engaging portion are provided so as to be spaced apart from each other substantially on both sides of the first spring engaging portion 25. The return coil spring 27 is hooked between the stopper portion 26 and the stopper portion 26. In this case, the return coil spring 27 functions as a tension spring, and the variable resistor Even when the rotating shaft portion 14B of 14 is in the original position, as shown in FIG. While the body of the spring 27 is in sliding contact with the outer peripheral surface of the ring 24, which is an arc-shaped guide member, The operation lever 20 extends in a shape that is bent and extended concentrically with the rotation direction of the bar 20. On the other hand, the habit of clockwise rotation is given in FIG. [0010] In the illustrated example, a collar 24A is provided on the end surface of the annular ring 24, and when the operation lever is rotated, The return coil spring 27 is prevented from coming off the outer peripheral surface of the annular ring 24. In the rear handshake member 10, when the single shot button 28 is pressed, it is operated and hit. A microswitch 29 is provided to stop the ball launching device. A circular lens member 31 is fitted in the center of the end surface of the front handshake member 30. It As before, the spiral coil spring is locked to the operating lever 20 and the front handshake member 30. In this configuration, when the front handshake member 30 is attached, the spiral coil spring is compressed Will be installed. On the other hand, in the present invention, the coil spring is adopted as the return spring. The first spring engaging portion 25 and the second spring engaging portion that are exposed to one side of the operating lever 20. It is hung between the stop 26 and not engaged with the front handshake member 30. Therefore, the front handshake member 30 is subject to the action of the return spring at the final stage of assembly. It is extremely easy to install without. Further, in the past, the action point of the spiral spring was separated from the surface of the operation lever 20 and the surface thereof. Since the spring is located at the point, the restoring force of the spring is slanted with respect to the rotating direction of the operation lever 20. It will work. [0011] On the other hand, in the present invention, the operation lever 20 is rotated in the same direction in parallel with the rotation direction. Therefore, the operating lever 20 itself and the rotary shaft portion 14 of the variable resistor 14 are operated. No unreasonable force is applied to B, etc., and there is no discomfort during operation, and smoothness is improved. Also, in the case of the conventional spiral spring type, the spiral spring has a relatively small radius. Inevitably becomes large, and relatively large force is required when setting this . On the other hand, in the present invention, since the coil spring is made to function as a tension spring, A small diameter spring is enough, and the force to rotate the operating lever is correspondingly small, and Since the expansion and contraction stroke of the spring becomes long, the rotation amount of the operation lever 20 becomes large. However, the operation lever 20 can be easily and smoothly rotated with a small force. Therefore, it is also possible to reduce the fatigue of the wrists and fingers caused by playing for a long time. [0012] In FIG. 4, in the lower part of the front frame 2, a rotary solenoid of the ball-striking launcher is installed. Do 4 is inserted. This rotary solenoid 4 or the mounting board 3 fixed on the back of the front frame 2 The output shaft 4'of the rotary solenoid 4 penetrates the mounting substrate 3 and projects to the back side. The base of the firing pestle 5 is fixed to its tip. The launching pestle 5 is provided with a habit of always rotating counterclockwise as viewed in FIG. When the rotary solenoid 4 is not energized, as shown in FIG. It is in the standby position farthest from the rule 7. Reference numerals 8 and 9 in the figure are stoppers that regulate the standby position and the elastic position of the launching punch 5. Is. In order to make the movement of the launching pestle 5 smooth, the stopper 8 is a rotating type and 9 is composed of an elastic member. [0013] Now, when the operation lever 20 is rotated clockwise as seen from the player, the variable resistor 1 The rotating shaft portion 14B of No. 4 is rotated and the resistance value thereof is changed. This resistance value 4 is transmitted to a control unit (not shown), and the control unit The re-solenoid 4 is intermittently biased by an electromagnetic force corresponding to the resistance value. That is, the firing pestle 5 resists the spring 6 each time by the electromagnetic force corresponding to the resistance value. , Rotate clockwise in FIG. With each rotation, the tip 5A of the launching punch 5 strikes the ball of the launch rail base 7A, The hit ball passes through the launch rail 7 and is hit into the game area of the game board. [0014] [Effect of the device] As described above, the operation dial of the present invention is provided on the front handshake member side of the operation lever. The first spring locking portion is provided on the facing surface, and the second spring locking portion is provided on the rear handshake member. , The second spring locking portion penetrates the slit of the operation lever and is located in front of the operation lever. Facing the handshake member side and returning between the first spring locking portion and the second spring locking portion Apply a coil spring as a spring to make the coil spring highly elastic. The elastic force in the axial direction of the On the opposite surface, this return coil spring is extended in an arc shape along the turning direction of the operating lever. An arc-shaped guide portion for contracting is provided. Therefore, with the rear handshake member and the operating lever assembled, set the return coil spring It is possible to stop along the rear part with the rear handshake member and the spring locking member of the operating lever. As a result, the assembly work is easier than in the past. [0015] Also, in the present invention, the return coil spring is stretchable along the direction in which the operation lever is rotated. Since the elastic force acts in the axial direction of the rich coil, the conventional spiral coil spring can be wound. Unlike the elastic force in the opposite direction, the operating lever itself or the operated member connected to it, for example, Not only is the turning shaft of the variable resistor unreasonable force, but smooth operation is possible. Durability can be increased. In addition, the return coil spring utilizes the elastic force of the coil, which is highly elastic, in the axial direction. Therefore, a coil spring with a small diameter is sufficient, and the force to rotate the operating lever is correspondingly increased. It can be small. Moreover, compared to the conventional spiral spring, the expansion and contraction stroke of the spring can be made longer. Therefore, even if the amount of rotation of the operating lever increases, the operating lever can be easily operated with a small force. It can be rotated smoothly. Therefore, it is also possible to reduce the fatigue of the wrists and fingers caused by playing for a long time.
