電気部品のクリック機構Electric component click mechanism
　この発明は回転操作される電気部品やスライド操作される電気部品において、操作時にクリック感（節度感）を発生させるためのクリック機構に関する。 The present invention relates to a click mechanism for generating a click feeling (moderation feeling) at the time of operation in an electric part that is rotated and an electric part that is operated by sliding.
　図1はこの種のクリック機構の従来例として特許文献１に記載されている構成を示したものである。図1中、１はスイッチの回転操作軸を支える軸受を示し、２は回転板を示す。 FIG. 1 shows a configuration described in Patent Document 1 as a conventional example of this type of click mechanism. In FIG. 1, reference numeral 1 denotes a bearing that supports the rotary operation shaft of the switch, and 2 denotes a rotating plate.
　軸受１は取り付け用ネジが外周に形成された取り付け部１ａと、取り付け部１ａの一端に一体に形成されたハウジング部１ｂとを備えている。取り付け部１ａには回転操作軸が挿通される軸穴が形成され、ハウジング部１ｂには軸穴が開口する凹部が形成され、この凹部の内周面に周方向に凹凸１ｃが形成されている。 The bearing 1 includes a mounting portion 1a having mounting screws formed on the outer periphery, and a housing portion 1b formed integrally with one end of the mounting portion 1a. A shaft hole through which the rotation operation shaft is inserted is formed in the attachment portion 1a, and a recess portion in which the shaft hole is opened is formed in the housing portion 1b. An unevenness 1c is formed in the circumferential direction on the inner peripheral surface of the recess portion. .
　回転板２はハウジング部１ｂに収容されており、その上面には凹部２aが形成されている。凹部２ａにはＵ字形をなすバネ３が収容配置され、さらにバネ３のＵ字の両脚部とそれぞれ対向して回転板２に形成された切り欠き２ｂに短い円柱状とされたクリック駒４がそれぞれ収容配置されている。２つのクリック駒４はバネ３の両脚部によって互いに反対方向に付勢され、ハウジング部１ｂに形成されている凹凸１ｃにそれぞれ弾接されている。 The rotating plate 2 is accommodated in the housing portion 1b, and a concave portion 2a is formed on the upper surface thereof. A U-shaped spring 3 is accommodated in the recess 2a, and a click piece 4 having a short columnar shape is formed in a notch 2b formed in the rotating plate 2 so as to face both U-shaped leg portions of the spring 3 respectively. Each is housed. The two click pieces 4 are urged in opposite directions by both leg portions of the spring 3 and elastically contact with the unevenness 1c formed on the housing portion 1b.
　回転板２の軸穴２ｃには回転操作軸が挿通され、これにより回転板２は回転操作軸と一体に回転する。この時、クリック駒４はハウジング部１ｂの凹凸１ｃに沿って移動し、これによりクリック感が発生するものとなっている。 Rotating operation shaft is inserted into the shaft hole 2c of the rotating plate 2, whereby the rotating plate 2 rotates integrally with the rotating operation shaft. At this time, the click piece 4 moves along the unevenness 1c of the housing portion 1b, thereby generating a click feeling.
　一方、図２は特許文献２に記載されているクリック機構を示したものである。図２中、５はハウジングを示し、６はロータを示す。また、７はバネ（弾性部材）を示す。 On the other hand, FIG. 2 shows a click mechanism described in Patent Document 2. In FIG. 2, 5 indicates a housing, and 6 indicates a rotor. Reference numeral 7 denotes a spring (elastic member).

A convex portion 7c is formed at the tip of the elastic arm portion 7b.
　ロータ６の基部６ａにはコ字状の溝６ｂが形成されており、この溝６ｂに屈曲部７ａが圧入されてバネ７がロータ６に取り付けられている。バネ７の凸部７ｃはハウジング５の内部に形成されている凹凸面５ａに弾接し、これによりロータ６の回転に伴うクリック感が得られるものとなっている。 A U-shaped groove 6 b is formed in the base 6 a of the rotor 6, and a bent portion 7 a is press-fitted into the groove 6 b so that the spring 7 is attached to the rotor 6. The convex portion 7 c of the spring 7 is in elastic contact with the concave-convex surface 5 a formed inside the housing 5, whereby a click feeling associated with the rotation of the rotor 6 is obtained.

　カバー１１０は中間板７０と同一形状とされ、中間板７０と同様、軸穴１１１、２つの位置決め穴１１２ａ、２つの固定穴１１２ｂ及び２つの位置決め突起１１３を備えている。カバー１１０は例えば樹脂製とされる。 The cover 110 has the same shape as the intermediate plate 70, and includes a shaft hole 111, two positioning holes 112 a, two fixing holes 112 b, and two positioning protrusions 113, as with the intermediate plate 70. The cover 110 is made of resin, for example.
　各部の組み立ては以下のように行われる。 The assembly of each part is performed as follows.
　回転操作軸１０は軸受２０に挿通され、その保持部１２の先端側に形成されている環状溝１２ａにリング３０を装着することにより抜け止めされる。 The rotation operation shaft 10 is inserted into the bearing 20 and is prevented from coming off by attaching a ring 30 to the annular groove 12a formed on the front end side of the holding portion 12.
　回転板４０はその軸部４４の軸穴４５及びそれと連通する軸穴４６に回転操作軸１０の駆動部１３が挿通されて軸受２０のハウジング部２２の凹部２４に収容される。そして、この状態でバネ５０が回転板４０の凹部４１に収容配置される（後で説明する図６Ａ,６Ｂ参照）。この際、バネ５０の両端部を例えばピンセットで挟み込み、Ｕ字を狭めることによって容易に凹部４１に入れ込むことができる。回転板４０の切り欠き４３はピンセットの逃げとなる。バネ５０の２箇所の凸部５０ａは回転板４０の２つの切り欠き４２にそれぞれ位置される。 The rotating plate 40 is accommodated in the recess 24 of the housing portion 22 of the bearing 20 through the shaft portion 45 of the shaft portion 44 and the shaft hole 46 communicating with the shaft portion 44 through which the drive portion 13 of the rotary operation shaft 10 is inserted. In this state, the spring 50 is accommodated in the recess 41 of the rotating plate 40 (see FIGS. 6A and 6B described later). At this time, both ends of the spring 50 can be easily inserted into the recess 41 by sandwiching the both ends with tweezers and narrowing the U-shape. The notch 43 of the rotating plate 40 is a tweezer escape. The two convex portions 50 a of the spring 50 are respectively positioned in the two notches 42 of the rotating plate 40.
　中間板７０はその軸穴７１に駆動部１３を挿通させ、回転板４０を収容したハウジング部の凹部２４を上から塞いでハウジング部２２の上面に取り付けられる。この時、中間板７０の位置決め突起７３はハウジング部２２の位置決め穴２２ａに嵌合される。
中間板７０の位置決め穴７２ａに下側接触子ホルダ８０の位置決め突起８６が嵌合され、中間板７０の上に下側接触子ホルダ８０が位置決め固定される。その上から下側接触子ホルダ８０の回転子収容凹部８１内に回転子９０のディスク部９２のほぼ下半分を配置するように、回転子９０の軸穴９４に回転操作軸１０の駆動部１３を挿通させつつ、回転軸９１の下端部を中間板７０の軸穴７１を通して回転板４０の軸穴４５に挿入係合させる。 The intermediate plate 70 is attached to the upper surface of the housing portion 22 by inserting the driving portion 13 through the shaft hole 71 and closing the concave portion 24 of the housing portion containing the rotating plate 40 from above. At this time, the positioning protrusion 73 of the intermediate plate 70 is fitted into the positioning hole 22 a of the housing portion 22.
The positioning protrusions 86 of the lower contact holder 80 are fitted into the positioning holes 72 a of the intermediate plate 70, and the lower contact holder 80 is positioned and fixed on the intermediate plate 70. The drive unit 13 of the rotary operation shaft 10 is inserted into the shaft hole 94 of the rotor 90 so that the substantially lower half of the disk portion 92 of the rotor 90 is disposed in the rotor receiving recess 81 of the lower contact holder 80 from above. The lower end portion of the rotating shaft 91 is inserted into and engaged with the shaft hole 45 of the rotating plate 40 through the shaft hole 71 of the intermediate plate 70.
　その回転子９０のディスク部９２のほぼ上半分を上側接触子ホルダ１００の回転子収容凹部１０１に収容するように、回転子９０の上から上側接触子ホルダ１００を被せ、下側接触子ホルダ８０に重ねて固定する。この時、上側接触子ホルダ１００の係合凸部１０３と係合凹部１０４が下側接触子ホルダ８０の係合凸部８３と係合凹部８４にそれぞれ嵌合し、互いに位置決めされる。 The upper contact holder 100 is covered from above the rotor 90 so that the upper half of the disk portion 92 of the rotor 90 is accommodated in the rotor accommodating recess 101 of the upper contact holder 100, and the lower contact holder 80. Overlay and fix. At this time, the engaging convex portion 103 and the engaging concave portion 104 of the upper contact holder 100 are fitted into the engaging convex portion 83 and the engaging concave portion 84 of the lower contact holder 80, respectively, and are positioned relative to each other.
　さらに、カバー１１０の軸穴１１１に回転子９０の回転軸９１の上端部を挿入させて上側接触子ホルダ１００の上にカバー１１０を重ねて位置決め突起１１３を位置決め穴１０５ａに嵌合し、位置決め穴１１２ａに位置決め突起１０６を嵌合する。これにより下側接触子ホルダ８０の接触子８７ａ，８８ａ，８９ａは回転子９０のディスク部９２の下面と弾接され、上側接触子ホルダ１００の接触子１０７ａ，１０８ａ，１０９ａは回転子９０のディスク部９２の上面と弾接される。 Further, the upper end portion of the rotating shaft 91 of the rotor 90 is inserted into the shaft hole 111 of the cover 110, the cover 110 is overlaid on the upper contact holder 100, and the positioning protrusion 113 is fitted into the positioning hole 105a. The positioning protrusion 106 is fitted to 112a. As a result, the contacts 87 a, 88 a, 89 a of the lower contact holder 80 are brought into elastic contact with the lower surface of the disk portion 92 of the rotor 90, and the contacts 107 a, 108 a, 109 a of the upper contact holder 100 are It is elastically contacted with the upper surface of the portion 92.
　このようにして各部を合体した状態で、カバー１１０の固定穴１１２ｂ、上側接触子ホルダ１００の固定穴１０５ｂ、下側接触子ホルダ８０の固定穴８５ｂ、中間板７０の固定穴７２ｂ、軸受２０の固定穴２２ｂに２本のリベット１２０を挿通してリベット１２０の先端をかしめることにより、各部が互いに固定一体化され、スイッチが完成する。 In a state where the respective parts are combined in this manner, the fixing hole 112b of the cover 110, the fixing hole 105b of the upper contact holder 100, the fixing hole 85b of the lower contact holder 80, the fixing hole 72b of the intermediate plate 70, and the bearing 20 By inserting the two rivets 120 into the fixing hole 22b and caulking the tip of the rivet 120, the respective parts are fixedly integrated with each other, and the switch is completed.
　上記のような構成とされたスイッチでは回転操作軸１０の回転により回転板４０及び回転子９０が一体に回転し、回転子９０の上側及び下側接触片９３ａ，９３ｂと、上側及び下側接触子ホルダ１００，８０の各接触子１０７ａ，１０８ａ，１０９ａ及び８７ａ，８８ａ，８９ａとの間で回転角度に応じた接離が行われ、所要のスイッチ開閉信号が得られる。 In the switch configured as described above, the rotating plate 40 and the rotor 90 are integrally rotated by the rotation of the rotary operation shaft 10, and the upper and lower contact pieces 93 a and 93 b of the rotor 90 and the upper and lower contacts are contacted. Contact with each contact 107a, 108a, 109a and 87a, 88a, 89a of the child holders 100, 80 is performed according to the rotation angle, and a required switch open / close signal is obtained.
　一方、回転板４０の外周部の切り欠き４２に位置し、外周部から突出しているバネ５０の凸部５０ａは、Ｕ字形をなすバネ５０のＵ字の両脚部によって互いに反対方向に付勢され、軸受２０のフランジ部２２の凹部２４の内周面に形成された凹凸２５に、その周面部分が押し付けられ、弾接されている。図６Ａ,６Ｂはこの様子を示したものであり、回転操作軸１０の図示は省略している。 On the other hand, the convex portions 50a of the spring 50 located at the notch 42 on the outer peripheral portion of the rotating plate 40 and projecting from the outer peripheral portion are urged in opposite directions by the U-shaped leg portions of the U-shaped spring 50. The peripheral surface portion is pressed against and elastically contacted with the irregularities 25 formed on the inner peripheral surface of the concave portion 24 of the flange portion 22 of the bearing 20. 6A and 6B show this state, and the rotation operation shaft 10 is not shown.
　以下、図６Ａ,６Ｂを参照して、このスイッチにおけるクリック機構を説明する。 Hereinafter, the click mechanism in this switch will be described with reference to FIGS. 6A and 6B.
　回転操作軸１０の回転に伴い、回転板４０が回転すると、バネ５０も回転板４０と共に回転する。この時、軸受２０のハウジング部２２の凹部２４の内周面に形成されている凹凸２５に沿って凸部５０ａが移動し、回転板４０から出入りする方向に動作するため、クリック感が発生する。 When the rotary plate 40 is rotated along with the rotation of the rotary operation shaft 10, the spring 50 is also rotated together with the rotary plate 40. At this time, the convex portion 50a moves along the concave and convex portions 25 formed on the inner peripheral surface of the concave portion 24 of the housing portion 22 of the bearing 20 and moves in and out of the rotating plate 40, so that a click feeling is generated. .
　上述したように、この例ではＵ字形をなすバネ５０のＵ字の両脚部に、ハウジング部２２に形成されている凹凸２５と弾接する凸部５０ａを一体形成したものとなっており、よって図1に示したバネ３と別体のクリック駒４を用いる従来のクリック機構に比し、部品点数の削減を図ることができる。 As described above, in this example, both the U-shaped leg portions of the U-shaped spring 50 are integrally formed with the convex portions 50a that are elastically contacted with the concave and convex portions 25 formed on the housing portion 22. Compared to the conventional click mechanism using the click piece 4 separately from the spring 3 shown in FIG. 1, the number of parts can be reduced.
　また、バネ５０はＵ字形とされているため、両凸部５０ａ間の領域全てをバネの腕として使用することができ、つまり凸部５０ａに弾接力を与える弾性変形領域として両凸部５０ａ間の領域全てを使用することができる。これにより、図２に示した従来のＷ字形状をなすバネ７と比べて、バネの腕の長さを長くすることができ、言い換えればバネの長さを有効に利用することができる。よって、高いステップトルクを容易に得ることができ、耐久性に優れたクリック機構を実現することができる。 Further, since the spring 50 is U-shaped, the entire region between the two convex portions 50a can be used as the arm of the spring, that is, between the two convex portions 50a as an elastic deformation region that gives elastic force to the convex portion 50a. All of these areas can be used. This makes it possible to increase the length of the spring arm as compared to the conventional W-shaped spring 7 shown in FIG. 2, in other words, to effectively use the length of the spring. Therefore, a high step torque can be easily obtained, and a click mechanism with excellent durability can be realized.
　加えて、バネ５０の凸部５０ａはこの例ではハウジング部２２の凹凸２５と線接触（線当たり）するため、安定したクリック感を得ることができ、またハウジング部２２の磨耗を低減することができる。 In addition, since the convex portion 50a of the spring 50 is in line contact (per line) with the irregularities 25 of the housing portion 22 in this example, a stable click feeling can be obtained, and wear of the housing portion 22 can be reduced. it can.
　上述した例ではバネ５０に板材を用いているが、これに限らず、線材を用いることもできる。図７Ａに示したバネ５１はバネ５０と同様の形状を線材を曲げて形成したものである。図７Ａ中、５１ａは凸部を示す。バネ５０に替えて、このような線材よりなるバネ５１を用いる場合、用いる個数は１個に限らず、複数個用いることもできる。バネ５１を複数個（例えば２～３個）重ねて用いるようにすれば、その分、バネ圧を高めることができ、高いステップトルクを得ることができる。 In the example described above, a plate material is used for the spring 50, but the present invention is not limited to this, and a wire material can also be used. A spring 51 shown in FIG. 7A is formed by bending a wire in the same shape as the spring 50. In FIG. 7A, 51a shows a convex part. When the springs 51 made of such a wire material are used instead of the springs 50, the number used is not limited to one, and a plurality of springs can be used. If a plurality (for example, 2 to 3) of springs 51 are used in an overlapping manner, the spring pressure can be increased correspondingly, and a high step torque can be obtained.
　一方、図７Ｂはハウジング部２２の凹凸２５と弾接する凸部を樹脂製としたものであり、この例では凸部５２ａはＵ字形をなす板バネ５２ｂに一体成形されて形成されている。凹凸２５と弾接する凸部５２ａの先端面は半円筒面とされている。バネ５０や５１に替え、このような構成のバネ５２を用いることもできる。なお、凸部５０ａ，５１ａ及び５２ａはいずれもＵ字形状をなすものとされているが、これに限らず、例えば半円形状等、他の形状とすることもできる。 On the other hand, in FIG. 7B, a convex portion that elastically contacts the concave and convex portion 25 of the housing portion 22 is made of resin. In this example, the convex portion 52a is integrally formed with a U-shaped leaf spring 52b. The front end surface of the convex portion 52a that elastically contacts the unevenness 25 is a semi-cylindrical surface. Instead of the springs 50 and 51, the spring 52 having such a configuration can also be used. In addition, although all the convex parts 50a, 51a, and 52a shall be U-shaped, it is not restricted to this, For example, it can also be set as other shapes, such as a semicircle shape.
　図８Ａ～図８Ｄはバネの他の形状例を示したものであり、図８Ａ～図８ＤではバネはＵ字形ではなく、一箇所が切り欠かれた円環状をなすものとされている。 8A to 8D show other examples of the shape of the spring. In FIGS. 8A to 8D, the spring is not U-shaped but has an annular shape with one portion cut out.
　図８Ａに示したバネ５３は板材よりなり、切り欠きを挟む円環の各半部に互いに外向きに突出して凸部５３ａが一体形成されている。なお、バネ５３は強いトルクを発生させるべく、両凸部５３ａ間の領域が幅広とされている。 The spring 53 shown in FIG. 8A is made of a plate material, and projecting portions 53a are integrally formed projecting outward from each half of the circular ring sandwiching the notch. In addition, the area | region between both the convex parts 53a is made wide so that the spring 53 may generate | occur | produce a strong torque.
　図８Ｂに示したバネ５４は図８Ａに示したバネ５３に対し、幅広部分をなしとしたものである。図８Ｂ中、５４ａは凸部を示す。 The spring 54 shown in FIG. 8B has a wider portion than the spring 53 shown in FIG. 8A. In FIG. 8B, 54a shows a convex part.
　図８Ｃに示したバネ５５はバネ５４と同様の形状を線材を曲げて形成したものである。図８Ｃ中、５５ａは凸部を示す。 The spring 55 shown in FIG. 8C is formed by bending a wire in the same shape as the spring 54. In FIG. 8C, 55a shows a convex part.
　図８Ｄに示したバネ５６は前述の図７Ｂに示したバネ５２と同様、凸部５６ａを樹脂製としたものであり、凸部５６ａは一箇所が切り欠かれた円環状をなす板バネ５６ｂに一体成形されて形成されている。凸部５６ａの先端面は半円筒面とされている。 The spring 56 shown in FIG. 8D has a convex portion 56a made of resin, similar to the spring 52 shown in FIG. 7B, and the convex portion 56a is an annular leaf spring 56b cut out at one place. It is integrally formed with. The front end surface of the convex portion 56a is a semi-cylindrical surface.
　図８Ｅは図８Ａ～図８Ｄに示したバネ５３～５６が収容配置される回転板４０’の形状を示したものであり、この例では回転板４０’はバネを収容する円環状の凹部４１’とバネの凸部が位置される２つの切り欠き４２を備えており、さらに凹部４１’と連通して回転板４０’の外周面に至るもう一つの切り欠き４９が設けられている。 FIG. 8E shows the shape of the rotating plate 40 ′ in which the springs 53 to 56 shown in FIGS. 8A to 8D are accommodated. In this example, the rotating plate 40 ′ has an annular recess 41 for accommodating the spring. 'And two notches 42 in which the protrusions of the springs are located, and another notch 49 that communicates with the recess 41' and reaches the outer peripheral surface of the rotating plate 40 'is provided.
　この切り欠き４９にはバネ５３～５６の切り欠かれた部分において、外側に向かって突出延長されている延長部５３ｂ，５４ｂ，５５ｂ，５６ｃが位置される。バネ５３（５４，５５，５６）を回転板４０’に組み込む際には例えばピンセットで一対の延長部５３ｂ（５４ｂ，５５ｂ，５６ｃ）を挟み込み、円環を狭めることによって容易に凹部４１’に入れ込むことができ、切り欠き４９はこの際のピンセットに対する逃げとなる。これらバネ５３～５６を用いる場合は円環の切り欠きを挟む各半部によって凸部５３ａ～５６ａは互いに反対方向に付勢される。なお、バネ５３を用いる場合は幅広部分に対応する溝が凹部４１’の底面に形成される。 In the notch 49, extended portions 53b, 54b, 55b, and 56c that are projected and extended outward are located at the notched portions of the springs 53 to 56. When assembling the spring 53 (54, 55, 56) into the rotating plate 40 ', for example, a pair of extension portions 53b (54b, 55b, 56c) are sandwiched between tweezers, and the ring is narrowed so that it can be easily put into the recess 41'. The notch 49 is an escape to the tweezers at this time. When these springs 53 to 56 are used, the convex portions 53a to 56a are urged in opposite directions by the respective half portions sandwiching the notch of the ring. When the spring 53 is used, a groove corresponding to the wide portion is formed on the bottom surface of the recess 41 '.
　以上、回転操作軸を有する電気部品のクリック機構について説明したが、この発明によるクリック機構はスライド操作つまみを有する直動タイプの電気部品にも適用することができる。図９Ａ,９Ｂはその構成を示したものであり、図９Ａ,９Ｂ中、３１０はスライド操作つまみを示し、３２０はハウジングを示す。 As described above, the click mechanism of the electric component having the rotation operation shaft has been described, but the click mechanism according to the present invention can also be applied to a linear motion type electric component having a slide operation knob. 9A and 9B show the configuration. In FIGS. 9A and 9B, 310 indicates a slide operation knob, and 320 indicates a housing.
　両脚部に凸部３４１が形成されたＵ字形のバネ３４０は可動体３５０に配置される。可動体３５０はスライド操作つまみ３１０に一体形成され、スライド操作つまみ３１０と一体にスライドする。可動体３５０はこの例では円板状とされ、その一面に凹部３５１が形成され、その凹部３５１から外周面に至る切り欠き３５２が径方向互いに反対側に形成されている。 A U-shaped spring 340 having convex portions 341 formed on both leg portions is disposed on the movable body 350. The movable body 350 is integrally formed with the slide operation knob 310 and slides integrally with the slide operation knob 310. In this example, the movable body 350 has a disk shape, and a concave portion 351 is formed on one surface thereof, and notches 352 extending from the concave portion 351 to the outer peripheral surface are formed on opposite sides in the radial direction.
　バネ３４０は可動体３５０の凹部３５１に収容配置され、２つの凸部３４１は周縁部の切り欠き３５２にそれぞれ位置される。凸部３４１は可動体３５０の周縁部から突出されている。 The spring 340 is accommodated and disposed in the concave portion 351 of the movable body 350, and the two convex portions 341 are respectively positioned in the notches 352 in the peripheral portion. The convex part 341 protrudes from the peripheral part of the movable body 350.
　ハウジング３２０には可動体３５０をスライド自在に収容する矩形形状の凹部３２１が形成され、さらにハウジング３２０の凹部３２１が形成されている面と隣接する面に凹部３２１の底面側と連通する細長形状の開口３２２が形成されている。可動体３５０は凹部３２１に配置され、スライド操作つまみ３１０は開口３２２から外部に突出され、開口３２２の長手方向にスライド可能とされている。 The housing 320 is formed with a rectangular recess 321 that slidably accommodates the movable body 350, and has an elongated shape that communicates with the bottom surface of the recess 321 on the surface adjacent to the surface of the housing 320 where the recess 321 is formed. An opening 322 is formed. The movable body 350 is disposed in the recess 321, and the slide operation knob 310 protrudes to the outside from the opening 322 so that it can slide in the longitudinal direction of the opening 322.
　スライド操作つまみ３１０と共にスライドする可動体３５０のスライド方向に沿う凹部３２１の内壁面には、山谷形状をなす凹凸３２３がスライド方向に配列されてそれぞれ形成されており、２つの凸部３４１はバネ３４０によって互いに反対方向に付勢されてこれら凹凸３２３にそれぞれ弾接されている。 On the inner wall surface of the concave portion 321 along the slide direction of the movable body 350 that slides together with the slide operation knob 310, concave and convex portions 323 having a valley shape are arranged in the slide direction, and the two convex portions 341 are springs 340. Are urged in opposite directions to be elastically contacted with these irregularities 323, respectively.
　この例ではこのような構造により、スライド操作つまみ３１０のスライド操作に伴い、クリック感が得られるものとなっている。なお、図９Ａ,９Ｂでは図示を省略しているが、スライド操作つまみ３１０の操作に伴い、動作されるスイッチや可変抵抗器等はハウジング３２０の凹部３２１が形成されている面側に配置され、その可動部分は可動体３５０と一体にスライドするように構成される。 In this example, with such a structure, a click feeling can be obtained with the slide operation of the slide operation knob 310. Although not shown in FIGS. 9A and 9B, the switch, variable resistor, and the like that are operated in accordance with the operation of the slide operation knob 310 are arranged on the surface side where the recess 321 of the housing 320 is formed, The movable part is configured to slide integrally with the movable body 350.
　図１０Ａ,１０Ｂは図９Ａ,９Ｂに示した構成に対し、スライド操作つまみ３１０が外部に突出する向きを変えた例を示したものであり、このような構成を採用することもできる。なお、図９Ａ,９Ｂと対応する部分には同一符号を付してある。 10A and 10B show an example in which the direction in which the slide operation knob 310 protrudes to the outside is changed with respect to the configuration shown in FIGS. 9A and 9B, and such a configuration can also be adopted. In addition, the same code | symbol is attached | subjected to the part corresponding to FIG. 9A, 9B.
