図7は図3に示す防滴部材140のB−B断面拡大図である。同図及び図3,図5に示すように、防滴部材140は、弾性材(例えばラバー等)を略リング状で薄板状に成形して構成されており、その外周の一部に上下方向に肉厚な肉厚部(外周側壁)147を設けると共に、その中央に円形の開口141を設けている。防滴部材140の上面の開口141の周囲の部分には、上方向に向かって筒状に突出する当接部143が形成されている。当接部143の内径寸法(即ち開口141の内径寸法)は、前記ケース100のケース本体101の外径寸法よりも少し小さい(略同一)寸法となっている。また当接部143の外周下部からその半径方向外方に向かって張り出して広がる肉薄部分は、当接部143の外周側を覆う接続部145となっている。そして接続部145の周囲の位置(180°対向する2箇所)に円弧状で上下方向に肉厚となっている前記肉厚部147が形成されている。言い換えれば、肉厚部147は防滴部材140の外周側壁の一部を構成しており、前記接続部145と共に防滴部材140の外周を形成している。   FIG. 7 is an enlarged cross-sectional view taken along the line BB of the drip-proof member 140 shown in FIG. As shown in FIG. 3 and FIGS. 3 and 5, the drip-proof member 140 is formed by forming an elastic material (for example, rubber or the like) into a thin ring shape in a substantially ring shape, and has a part of its outer periphery in a vertical direction. A thick wall portion (outer peripheral side wall) 147 and a circular opening 141 at the center thereof. A contact portion 143 projecting upward in a cylindrical shape is formed in a portion around the opening 141 on the upper surface of the drip-proof member 140. The inner diameter of the contact portion 143 (that is, the inner diameter of the opening 141) is slightly smaller (substantially the same) than the outer diameter of the case body 101 of the case 100. In addition, a thin portion that protrudes outward from the lower part of the outer periphery of the contact portion 143 in the radial direction and extends is a connecting portion 145 that covers the outer peripheral side of the contact portion 143. The thick portion 147 that is thick in the vertical direction in an arc shape is formed at a position around the connection portion 145 (two locations facing 180 °). In other words, the thick part 147 forms a part of the outer peripheral side wall of the drip-proof member 140, and forms the outer periphery of the drip-proof member 140 together with the connection part 145.

接続部145は、図7に示すように、当接部143の下端辺から斜め下外方に向けて突出し、次に水平となるように屈曲し、さらに斜め上方向に向けて屈曲した後に、肉厚部147に接続されている。接続部145はこのように屈曲することで、当接部143の内径の拡大縮小を、弾性を持って変形・吸収できる。同時にこのように屈曲することで、接続部145の中央にリング状の凹部146を形成している。また接続部145は薄板リング状であって何ら開口等は設けられていない。防滴部材140の外周の複数位置(4か所)には、外方に半円状に突出する突出部149が形成され、各突出部149に上下に貫通する係止部151が形成されている。各係止部151は、前記ケース100の取付部119を挿入する位置に形成されている。各突出部149を含む、肉厚部147を設けていない部分は凹部153となっている。   As shown in FIG. 7, the connecting portion 145 projects obliquely downward and outward from the lower end side of the contact portion 143, then bends horizontally, and further bends obliquely upward. It is connected to the thick part 147. By bending the connection portion 145 in this manner, the expansion and contraction of the inner diameter of the contact portion 143 can be elastically deformed and absorbed. At the same time, by bending in this manner, a ring-shaped concave portion 146 is formed at the center of the connection portion 145. The connecting portion 145 has a thin ring shape and is not provided with any opening or the like. At a plurality of positions (four places) on the outer periphery of the drip-proof member 140, projecting portions 149 projecting outward in a semicircular shape are formed, and locking portions 151 penetrating vertically are formed at each projecting portion 149. I have. Each locking portion 151 is formed at a position where the mounting portion 119 of the case 100 is inserted. Portions where the thick portions 147 are not provided, including the protruding portions 149, are concave portions 153.

スペーサ部材160は薄板リング状であり、フッ素樹脂等の摺動性に優れた合成樹脂フィルムによって形成されており、ケース100の上面部107の外形と略一致する円形の外形を有し、中央に前記ケース100のつまみ挿通孔109と略同一内径の開口161を設けて構成されている。このスペーサ部材160は、回転つまみ200とケース100(上面部107)の間に設置されて回転つまみ200の回転時のケース100に対する回転摺動性を向上させると共に、ケース100及び回転つまみ200に密着してこの部分からの液体の浸入を防止するための部材である。   The spacer member 160 has a thin ring shape, is formed of a synthetic resin film having excellent slidability such as fluororesin, has a circular outer shape substantially matching the outer shape of the upper surface portion 107 of the case 100, and has a An opening 161 having substantially the same inner diameter as the knob insertion hole 109 of the case 100 is provided. The spacer member 160 is provided between the rotary knob 200 and the case 100 (upper surface portion 107) to improve the rotational sliding property of the rotary knob 200 with respect to the case 100 when the rotary knob 200 rotates, and to be in close contact with the case 100 and the rotary knob 200. This is a member for preventing liquid from entering from this portion.

第2防滴部材170は弾性材(例えばラバーやスポンジ等)を略リング状に形成して構成されている。第2防滴部材170は、外周側に設けた横断面矩形状でリング状の基部171と、基部171の内周側から内側に向かって薄板状に突出する連結部173と、連結部173の内周先端辺部分に形成した横断面矩形状でリング状の先端部175とを具備している。連結部173は、基部171の内周から突出して斜め上方に向かって筒状(円錐台形の筒状)に突出する形状に形成されている。   The second drip-proof member 170 is formed by forming an elastic material (for example, rubber or sponge) into a substantially ring shape. The second drip-proof member 170 includes a ring-shaped base 171 provided on the outer peripheral side and having a rectangular cross section, a connecting part 173 projecting inward from the inner peripheral side of the base 171, and a connecting part 173. A ring-shaped tip portion 175 having a rectangular cross section formed at the tip portion of the inner periphery is provided. The connecting portion 173 is formed in a shape projecting from the inner periphery of the base portion 171 and projecting obliquely upward in a tubular shape (a truncated conical tubular shape).

押釦つまみ180は合成樹脂の成形品であり、略円板状の本体部181と、本体部181の下面中央から下方向に向かって突出する柱状の押圧部183とを具備し、また本体部181の外周下部から薄板リング状のつば部185を突出して構成されている。押圧部183の外周側面には180°反対側から半径方向に向かって突出し上下方向に延びる突条からなる一対の回り止め係合部187が設けられている。また本体部181の下面の押圧部183の周囲を囲む部分には、リング状で凹状の防滴部材当接部189が設けられている。   The push button knob 180 is a molded product of a synthetic resin, and includes a substantially disk-shaped main body 181 and a columnar pressing part 183 protruding downward from the center of the lower surface of the main body 181. A thin plate ring-shaped flange portion 185 is projected from the lower part of the outer periphery of the main body. On the outer peripheral side surface of the pressing portion 183, a pair of detent engaging portions 187 each formed of a ridge projecting in the radial direction from the opposite side by 180 ° and extending in the vertical direction are provided. A ring-shaped concave drip-proof member contact portion 189 is provided in a portion surrounding the pressing portion 183 on the lower surface of the main body portion 181.

回転つまみ200は合成樹脂の成形品であり、略円板状の本体部201の外周から下方に向かって筒状に側壁部203を突出して構成されている。本体部201の中央には上下に貫通して前記押釦つまみ180の本体部181を挿入する内径寸法(但しつば部185の外形寸法よりも小さい内径寸法)の円形の開口部205が設けられている。本体部201の下面の開口部205の周囲には下方向に向かって突出する筒状の軸支部207が設けられている。軸支部207の内径寸法は前記押釦つまみ180のつば部185を上下動自在に収納できる寸法であり、軸支部207の外径寸法は前記ケース100のつまみ挿通孔109に挿入されて回動自在に軸支される寸法である。即ち言い換えればケース100に設けたつまみ挿通孔109内に回動自在に挿入される軸支部207中央に開口部205を設けている。   The rotary knob 200 is a molded product of a synthetic resin, and is formed by projecting the side wall 203 in a cylindrical shape downward from the outer periphery of the substantially disk-shaped main body 201. At the center of the main body 201, a circular opening 205 having an inner diameter (an inner diameter smaller than the outer diameter of the collar 185) for vertically inserting the main body 181 of the push button knob 180 is provided. . A cylindrical support 207 protruding downward is provided around the opening 205 on the lower surface of the main body 201. The inner diameter of the shaft support portion 207 is a size capable of vertically storing the collar portion 185 of the push button knob 180, and the outer diameter size of the shaft support portion 207 is inserted into the knob insertion hole 109 of the case 100 so as to be rotatable. This is the dimension supported by the shaft. That is, in other words, the opening 205 is provided at the center of the shaft support 207 that is rotatably inserted into the knob insertion hole 109 provided in the case 100.

軸支部207の下端辺の所定位置(6か所)からは、下方向に向かって小突起状の固定部209が突出している。各固定部209は前記クリック板80の各取付部87に対向する位置に設けられている。また回転つまみ200の開口部205の内径寸法は、軸支部207の内径寸法よりも小さく、これによって回転つまみ200下面の開口部205の周囲につば部当接部211を形成している。また回転つまみ200の側壁部203の下部外周から外方に向けてつば部213が突出している。   From a predetermined position (six places) on the lower end side of the shaft support 207, a small protrusion-shaped fixing portion 209 protrudes downward. Each fixing portion 209 is provided at a position facing each mounting portion 87 of the click plate 80. The inner diameter of the opening 205 of the rotary knob 200 is smaller than the inner diameter of the shaft support 207, thereby forming a flange contact portion 211 around the opening 205 on the lower surface of the rotary knob 200. A collar portion 213 protrudes outward from the lower periphery of the side wall portion 203 of the rotary knob 200.

外装ケース230は合成樹脂の成形品であり、前記回転つまみ200の上面を露出する開口231を有して構成されている。開口231の内径寸法は、前記回転つまみ200の側壁部203の外径寸法よりも大きく、つば部213の外径寸法よりも小さく形成されている。   The outer case 230 is a molded product of a synthetic resin and has an opening 231 exposing the upper surface of the rotary knob 200. The inner diameter of the opening 231 is larger than the outer diameter of the side wall 203 of the rotary knob 200 and smaller than the outer diameter of the collar 213.

次に回転式電子部品1−1の組立方法を説明する。まず回転つまみ200の本体部201の下面にスペーサ部材160を設置する。このとき回転つまみ200の軸支部207をスペーサ部材160の開口161に挿入する。次に、回転つまみ200の開口部205にその下側から押釦つまみ180の本体部181を挿入し、本体部181の上面を開口部205から回転つまみ200の上面側に露出させる。このときつば部185の上面はつば部当接部211に当接する。次に押釦つまみ180の下側に第2防滴部材170を設置し、その際、押釦つまみ180の防滴部材当接部189に第2防滴部材170の先端部175を当接する。   Next, a method of assembling the rotary electronic component 1-1 will be described. First, the spacer member 160 is installed on the lower surface of the main body 201 of the rotary knob 200. At this time, the shaft support 207 of the rotary knob 200 is inserted into the opening 161 of the spacer member 160. Next, the main body 181 of the push button knob 180 is inserted into the opening 205 of the rotary knob 200 from below, and the upper surface of the main body 181 is exposed from the opening 205 to the upper surface of the rotary knob 200. At this time, the upper surface of the collar part 185 contacts the collar part contact part 211. Next, the second drip-proof member 170 is installed below the push-button knob 180, and at this time, the tip 175 of the second drip-proof member 170 abuts against the drip-proof member contact portion 189 of the push-button knob 180.

次にその下側に防滴部材140とケース100とを設置し、その際、ケース本体101を防滴部材140の開口141内に挿入(圧入)し、同時にケース100の各取付部119を防滴部材140の各突出部151に挿入し、さらに回転つまみ200の軸支部207をケース100のつまみ挿通孔109に回動自在に挿入する。このとき回転つまみ200の側壁部203の内周側にケース本体101と、このケース本体101の外周に当接する防滴部材140の当接部143が入り込む。   Next, the drip-proof member 140 and the case 100 are placed under the drip-proof member 140. At this time, the case main body 101 is inserted (press-fitted) into the opening 141 of the drip-proof member 140, and at the same time, each mounting portion 119 of the case 100 is prevented. The rotary member 200 is inserted into each of the protrusions 151 of the drop member 140, and the pivot support 207 of the rotary knob 200 is rotatably inserted into the knob insertion hole 109 of the case 100. At this time, the case main body 101 and the contact portion 143 of the drip-proof member 140 that comes into contact with the outer periphery of the case main body 101 enter the inner peripheral side of the side wall 203 of the rotary knob 200.

次にケース100のつまみ挿通孔109の下側に露出した回転つまみ200の軸支部207の下面にクリック板80と摺動子70とを重ね合わせて設置し、その際軸支部207に設けた各固定部209をクリック板80の各取付部87と摺動子70の各取付固定部73に挿入し、挿入した各固定部209の先端を熱カシメして固定する。このときクリック板80(本体部81)はケース100の下面のつまみ挿通孔109の周囲の部分に当接する。これによってケース100に対して回転つまみ200とクリック板80と摺動子70が一体に回転自在になる。またこのとき、第2防滴部材170の基部171はクリック板80(本体部81)上に当接し、先端部175は押釦つまみ180の防滴部材当接部189に当接して少し押し潰され、これによって両者間が弾発されることで押釦つまみ180が押し上げられる。同時に第2防滴部材170によって、その内側の空間が封止される。   Next, the click plate 80 and the slider 70 are superposed and installed on the lower surface of the pivot support 207 of the rotary knob 200 exposed below the knob insertion hole 109 of the case 100. The fixing part 209 is inserted into each mounting part 87 of the click plate 80 and each mounting fixing part 73 of the slider 70, and the tip of each inserted fixing part 209 is fixed by heat caulking. At this time, the click plate 80 (the main body portion 81) comes into contact with a portion around the knob insertion hole 109 on the lower surface of the case 100. As a result, the rotary knob 200, the click plate 80, and the slider 70 become freely rotatable integrally with the case 100. At this time, the base 171 of the second drip-proof member 170 abuts on the click plate 80 (the main body 81), and the tip 175 abuts on the drip-proof member abutment 189 of the push button knob 180 and is slightly crushed. As a result, the push button knob 180 is pushed up by being repelled between them. At the same time, the space inside the second drip-proof member 170 is sealed.

次にその下側に第1回路基板30と基台40とを設置し、その際、ケース100の各取付用突部113を第1回路基板30の各挿通部33と基台40の各挿入部47に挿入し、さらに押釦つまみ180の押圧部183を基台40の押圧部挿通部45に挿入する。そして基台40の下面から突出するケース100の各取付用突部113の先端を熱カシメする。これによって、摺動子70の摺動接点77が第1回路基板30の摺接パターン35に弾接する。   Next, the first circuit board 30 and the base 40 are installed under the lower surface thereof. At this time, the mounting projections 113 of the case 100 are inserted into the respective insertion portions 33 of the first circuit board 30 and the respective insertions of the base 40. The pressing portion 183 of the push button knob 180 is further inserted into the pressing portion insertion portion 45 of the base 40. Then, the tip of each mounting projection 113 of the case 100 projecting from the lower surface of the base 40 is caulked. Thereby, the sliding contact 77 of the slider 70 elastically contacts the sliding contact pattern 35 of the first circuit board 30.

そして前記組立体の下側に、第2回路基板20と取付板10を配置し、その際、基台40の各取付部117を第2回路基板20の各取付部27と取付板10の各取付部11に挿入する。そして取付板10の下面から突出する各取付部117の先端を熱カシメによって固定する。なお、上記取付板10までの組み立ては、回転つまみ200を下側に向けて(上下逆転させて)、その他の部品を順番に上から積層していくことで組み立てることができるため、自動機による組み立てを行い易い。自動機による組み立てを行うことで人件費を削減でき、製造コストの削減を図ることができる。次に、前記組立体の上側に外装ケース230を配置し、図示しない位置で、外装ケース230と取付板10間を固定する。このとき外装ケース230の開口231から回転つまみ200の上部の部分が露出する。これによって、回転式電子部品1−1の組み立てが完了する。なお上記組立手順はその一例であり、他の各種異なる組立手順を用いて組み立てても良いことはいうまでもない。   Then, the second circuit board 20 and the mounting plate 10 are arranged below the assembly, and at this time, each mounting portion 117 of the base 40 is connected to each mounting portion 27 of the second circuit board 20 and each mounting plate 10. Insert it into the mounting part 11. Then, the tip of each mounting portion 117 protruding from the lower surface of the mounting plate 10 is fixed by thermal caulking. The assembly up to the mounting plate 10 can be performed by turning the rotary knob 200 downward (inverting upside down) and stacking other components in order from the top, so that an automatic machine is used. Easy to assemble. By assembling with an automatic machine, labor costs can be reduced and manufacturing costs can be reduced. Next, an outer case 230 is arranged above the assembly, and the outer case 230 and the mounting plate 10 are fixed at a position (not shown). At this time, the upper part of the rotary knob 200 is exposed from the opening 231 of the outer case 230. Thus, the assembly of the rotary electronic component 1-1 is completed. Note that the above assembling procedure is one example, and it goes without saying that the assembling may be performed using other various assembling procedures.

そして上記回転式電子部品1−1の回転つまみ200を回転操作すると、つまみ挿通孔109を介して電気的機能部収納空間A1内に配置されたクリック板80及び摺動子70がこれと一体に回転し、これによってクリック板80のクリック弾接部91がケース100のクリック係合部115に弾接係合してクリック感触が生じると共に、摺動子70の摺動接点77が第1回路基板30の摺接パターン35上を摺動して摺接パターン35の検出出力が変化する。なお回転つまみ200を回転した際、押釦つまみ180はその押圧部183の回り止め係合部187が基台40の押圧部挿通部45に係合しているので回転しない。また回転つまみ200を回転した際の回転抵抗(回転トルク)には、回転つまみ200と一体に回転する第2防滴部材170の先端部175が、静止している押釦つまみ180の防滴部材当接部189上を摺動する抵抗が含まれるが、この回転抵抗は小さい。一方、静止側の部材である防滴部材140の当接部143は、静止側のケース100に当接しているので、回転つまみ200の回転が防滴部材140によって阻害されることは全くなく、その回転抵抗の増加はなく、スムーズに回転させることができる。   When the rotary knob 200 of the rotary electronic component 1-1 is rotated, the click plate 80 and the slider 70 disposed in the electrical function unit storage space A1 via the knob insertion hole 109 are integrally formed therewith. As a result, the click elastic contact portion 91 of the click plate 80 elastically engages with the click engaging portion 115 of the case 100 to generate a click feeling, and the sliding contact 77 of the slider 70 moves to the first circuit board. The detection output of the sliding contact pattern 35 changes by sliding on the 30 sliding contact patterns 35. When the rotary knob 200 is rotated, the push button knob 180 does not rotate because the rotation preventing engagement portion 187 of the pressing portion 183 is engaged with the pressing portion insertion portion 45 of the base 40. The rotation resistance (rotation torque) when rotating the rotary knob 200 includes the tip 175 of the second drip-proof member 170 that rotates integrally with the rotary knob 200, and the tip of the stationary push-button knob 180 against the drip-proof member. A resistance that slides on the contact portion 189 is included, but the rotation resistance is small. On the other hand, since the contact portion 143 of the drip-proof member 140, which is a stationary member, is in contact with the stationary-side case 100, the rotation of the rotary knob 200 is not hindered by the drip-proof member 140 at all. The rotation can be smoothly performed without increasing the rotation resistance.

一方、押釦つまみ180の本体部181の上面を押圧すると、押釦つまみ180が下降してその押圧部183が中央スイッチ21の反転板を押圧して反転させ、これによって中央スイッチ21がオンする。押釦つまみ180への押圧を解除すれば、前記反転板及び第2防滴部材170は元の形状に自動復帰し、押釦つまみ180は押し上げられて中央スイッチ21はオフする。   On the other hand, when the upper surface of the main body portion 181 of the push button knob 180 is pressed, the push button knob 180 is lowered, and the pressing portion 183 presses the reversing plate of the central switch 21 to invert, thereby turning on the central switch 21. When the pressing on the push button knob 180 is released, the reversing plate and the second drip-proof member 170 automatically return to the original shape, the push button knob 180 is pushed up, and the central switch 21 is turned off.

さらに回転つまみ200の本体部201上面の、前記基台40の何れかの押圧部49に対応する部分を下方向に押圧すると、ケース100のヒンジ部105が撓むことで、基台40上に設置されている各構成部品(ケース本体101や回転つまみ200等)が基台40と一体に押圧された方向に傾いて揺動し、下降した側の押圧部49がこれに対向する押圧スイッチ23の反転板を押圧して反転させてその押圧スイッチ23をオンする。前記回転つまみ200への押圧を解除すれば、前記反転板及びヒンジ部105の自動復帰力で基台40及びその上の回転つまみ200を含む各構成部品が一体に元の位置に自動復帰し、押圧スイッチ23はオフする。   Further, when a portion of the upper surface of the main body 201 of the rotary knob 200 corresponding to any of the pressing portions 49 of the base 40 is pressed downward, the hinge portion 105 of the case 100 bends, and Each of the installed components (the case body 101, the rotary knob 200, and the like) is tilted and swung in a direction pressed integrally with the base 40, and the pressing portion 49 on the lowered side is pressed by the pressing switch 23 opposed thereto. Is pressed and turned over to turn on the pressing switch 23. When the pressing on the rotary knob 200 is released, the base 40 and the respective components including the rotary knob 200 thereon automatically return to the original position automatically by the automatic return force of the reversing plate and the hinge portion 105, The press switch 23 turns off.

次にこの回転式電子部品1−1の防滴機能について説明する。液体は、外装ケース230の開口231と回転つまみ200の外周の間の隙間S1(図2参照)の部分と、回転つまみ200の開口部205と押釦つまみ180の本体部181の間の隙間S2の部分とから浸入する。隙間S2から浸入する液体は、第2防滴部材170によって、その内部への浸入が阻止される。   Next, the drip-proof function of the rotary electronic component 1-1 will be described. The liquid is formed in a gap S1 (see FIG. 2) between the opening 231 of the outer case 230 and the outer periphery of the rotary knob 200, and a gap S2 between the opening 205 of the rotary knob 200 and the main body 181 of the push button knob 180. Infiltrate from the part and from. The liquid that penetrates from the gap S2 is prevented from penetrating into the inside by the second drip-proof member 170.

一方、隙間S1から浸入する液体は、防滴部材140の接続部145の上面に落ちる。ここで図6は図1に示す回転式電子部品1−1から、外装ケース230、回転つまみ200、押釦つまみ180、第2防滴部材170、スペーサ部材160を取り除いて示す斜視図である。同図にも示すように、ケース100(ケース本体101)の外周側面を囲むように弾性を有する防滴部材140の当接部143を当接(弾接)させて密閉しているので、前記隙間S1から浸入した液体が、ケース100(ケース本体101)の外周側面を伝ってケース100(ケース本体101)の下側からその内側、即ち電気的機能部収納空間A1内に浸入することは阻止される。   On the other hand, the liquid that enters from the gap S1 falls on the upper surface of the connection portion 145 of the drip-proof member 140. Here, FIG. 6 is a perspective view of the rotary electronic component 1-1 shown in FIG. 1 with the outer case 230, the rotary knob 200, the push button knob 180, the second drip-proof member 170, and the spacer member 160 removed. As shown in the figure, the contact portion 143 of the elastic drip-proof member 140 is brought into contact (elastic contact) so as to surround the outer peripheral side surface of the case 100 (the case main body 101), so that the case 100 is sealed. The liquid that has entered through the gap S1 is prevented from traveling along the outer peripheral side surface of the case 100 (the case main body 101) from the lower side of the case 100 (the case main body 101) to the inside, that is, into the electrical function unit storage space A1. Is done.

一方、防滴部材140の外周上面(接続部145の外周上面であり、挟持される肉厚部147の上面を含む)は、図2に示すように、外装ケース230下面の開口231の全周囲に密着しているので、隙間S1から浸入した液体が、前記外周上面を越えてその外側から第2回路基板20側に浸入することは確実に阻止される。また防滴部材140の接続部145は、ケース100のヒンジ部105の上部全体を覆っているので、ケース本体101とヒンジ部105(さらには固定部103)との間に生じる開口a1(図4,図5参照)の部分は容易且つ確実に塞がれ、この開口a1から第2回路基板20側への液体の浸入が確実に阻止される。また接続部145には、凹部146が設けられているので、隙間S1から浸入した液体はこの凹部146に溜まり、当接部143や肉厚部147側に移動しにくく、この点からも防滴効果を高めることができる。また、取付板10と基台40の間には、ケース本体101と共に揺動する基台40によって操作される第2電気的機能部(中央スイッチ21と押圧スイッチ23)が設置されているが、上記のような防滴効果を有するため、この第2電気的機能部への液体の浸入も、これを確実に防止することができる。   On the other hand, the outer peripheral upper surface of the drip-proof member 140 (the outer peripheral upper surface of the connection portion 145 and the upper surface of the thick portion 147 to be sandwiched) is, as shown in FIG. Therefore, the liquid that has entered through the gap S1 is reliably prevented from entering the second circuit board 20 from outside beyond the outer peripheral upper surface. Further, since the connecting portion 145 of the drip-proof member 140 covers the entire upper portion of the hinge portion 105 of the case 100, the opening a1 formed between the case main body 101 and the hinge portion 105 (further, the fixing portion 103) (FIG. 4). , FIG. 5) is easily and reliably closed, and the intrusion of the liquid from the opening a1 to the second circuit board 20 is reliably prevented. Further, since the connection portion 145 is provided with the concave portion 146, the liquid that has entered through the gap S1 accumulates in the concave portion 146, and is difficult to move to the contact portion 143 or the thick portion 147 side. The effect can be enhanced. In addition, between the mounting plate 10 and the base 40, a second electrical function unit (the center switch 21 and the pressing switch 23) operated by the base 40 that swings together with the case main body 101 is installed. Since it has the above-described drip-proof effect, it is possible to reliably prevent the liquid from entering the second electrical functional unit.

さらに上記回転式電子部品1−1においては、防滴部材140の当接部143が、回転つまみ200の側壁部203の内周側に位置しているので、回転つまみ200の外周側の隙間S1から浸入してくる液体が、側壁部203の下端辺よりも高い位置にある当接部143に付着しにくくなり、この点からも、電気的機能部収納空間A1内への液体の浸入を効果的に防止することができるばかりか、回転式電子部品1−1の高さ寸法を小さくすることができる。   Further, in the rotary electronic component 1-1, since the contact portion 143 of the drip-proof member 140 is located on the inner peripheral side of the side wall 203 of the rotary knob 200, the clearance S1 on the outer peripheral side of the rotary knob 200 is provided. This makes it difficult for the liquid that has entered from above to adhere to the contact portion 143 located at a position higher than the lower end side of the side wall portion 203. This also prevents the liquid from entering the electrical function unit storage space A1. Not only can be prevented, but also the height of the rotary electronic component 1-1 can be reduced.

図8〜図12はそれぞれ、防滴部材140の接続部145の外周部分(肉厚部の部分を含む)を取付板10と外装ケース230によって挟持する構造の他の例を示す要部拡大断面図である。図8に示す例においては、肉厚部を設けず、接続部145の外周部分を屈曲させてその上面を外装ケース230の下面に当接し、一方接続部145の外周部分の下面を取付板10上に突設させた凸部15の上端面に当接し、これによって上記接続部145の外周部分をその上下から挟持する構成としている。また図9に示す例においては、肉厚部を設けず、接続部145の外周部分を屈曲させてその下面を取付板10(その上の第2回路基板20)の上面に当接し、一方接続部145の外周部分の上面を外装ケース230の下面から突設させた凸部233の下端面に当接し、これによって上記接続部145の外周部分をその上下から挟持する構成としている。また図10に示す例においては、肉厚部147Aの高さ寸法を短く形成すると共に、取付板10上に凸部15Aを突設させ、これによって、肉厚部147Aを、外装ケース230の下面と凸部15Aの上端面とで挟持する構成としている。また図11に示す例においては、肉厚部147Bの高さ寸法を短く形成すると共に、外装ケース230の下面から凸部233Bを突設させ、これによって、肉厚部147Bを、凸部233Bの下端面と取付板10(その上の第2回路基板20)の上面とで挟持する構成としている。また図12に示す例においては、肉厚部147Cの高さ寸法を短く形成すると共に、外装ケース230の下面から凸部233Cを突設させ、且つ取付板10上に凸部15Cを突設させ、これによって、肉厚部147Cを、凸部233Cの下端面と凸部15Cの上端面とで挟持する構成としている。即ち、防滴部材140の接続部145の外周部分(肉厚部の部分を含む)の、取付板10と外装ケース230による挟持構造には種々の変形が可能であり、肉厚部は必ずしも必要ない。   8 to 12 are enlarged cross-sectional views of a main part showing another example of a structure in which an outer peripheral portion (including a thick portion) of the connection portion 145 of the drip-proof member 140 is sandwiched between the mounting plate 10 and the outer case 230. FIG. In the example shown in FIG. 8, the thick portion is not provided, and the outer peripheral portion of the connection portion 145 is bent so that the upper surface thereof is in contact with the lower surface of the outer case 230, while the lower surface of the outer peripheral portion of the connection portion 145 is connected to the mounting plate 10. It comes into contact with the upper end surface of the convex portion 15 projecting upward, whereby the outer peripheral portion of the connection portion 145 is sandwiched from above and below. In the example shown in FIG. 9, the thick portion is not provided, the outer peripheral portion of the connection portion 145 is bent, and the lower surface thereof is in contact with the upper surface of the mounting plate 10 (the second circuit board 20 thereon), and the one-side connection is performed. The upper surface of the outer peripheral portion of the portion 145 abuts on the lower end surface of the convex portion 233 protruding from the lower surface of the outer case 230, thereby holding the outer peripheral portion of the connection portion 145 from above and below. In the example shown in FIG. 10, the height of the thick portion 147A is reduced, and the convex portion 15A protrudes from the mounting plate 10, whereby the thick portion 147A is formed on the lower surface of the outer case 230. And the upper end surface of the projection 15A. In the example shown in FIG. 11, the height of the thick portion 147B is formed to be short, and the convex portion 233B is protruded from the lower surface of the outer case 230, so that the thick portion 147B is formed in the convex portion 233B. It is configured to be sandwiched between the lower end surface and the upper surface of the mounting plate 10 (the second circuit board 20 thereon). In the example shown in FIG. 12, the height of the thick portion 147 </ b> C is made shorter, the protrusion 233 </ b> C protrudes from the lower surface of the outer case 230, and the protrusion 15 </ b> C protrudes on the mounting plate 10. Thus, the thick portion 147C is sandwiched between the lower end surface of the projection 233C and the upper end surface of the projection 15C. That is, the outer peripheral portion (including the thick portion) of the connecting portion 145 of the drip-proof member 140 can be variously deformed in the structure for holding the mounting plate 10 and the outer case 230, and the thick portion is not necessarily required. Absent.

また取付板10の形状・寸法等の関係で、防滴部材140の肉厚部147と対向する位置に取付板10が設けられていない部分があり、その部分の肉厚部147を部分的に省略している(凹部153を設けた部分)が、前記省略して肉薄になった部分(接続部145の外周部分)は、取付板10以外の図示しない他の部品と外装ケース230によって挟持するように構成しても良い。また上記回転式電子部品1−1では、防滴部材140の肉厚部147中に、ケース100の固定部103を避けるためにも前記凹部153を設けているが、前記肉厚部147を前記固定部103の外周側を囲むように形成してもよく、さらに肉厚部147をケース100の固定部103とヒンジ部105の全周を囲むように全周に設けても良い。   Also, due to the shape and dimensions of the mounting plate 10, there is a portion where the mounting plate 10 is not provided at a position facing the thick portion 147 of the drip-proof member 140, and the thick portion 147 of that portion is partially removed. The omitted portion (the portion provided with the concave portion 153), but the omitted portion (the outer peripheral portion of the connection portion 145) is sandwiched by other components (not shown) other than the mounting plate 10 by the exterior case 230. It may be configured as follows. In the rotary electronic component 1-1, the concave portion 153 is provided in the thick portion 147 of the drip-proof member 140 in order to avoid the fixing portion 103 of the case 100. The fixing portion 103 may be formed so as to surround the outer peripheral side, and the thick portion 147 may be provided all around the fixing portion 103 and the hinge portion 105 of the case 100 so as to surround the entire periphery.
