Description

本発明は、操作つまみ等の移動体が移動した位置から所定の復帰位置に自動復帰する自動復帰型電子部品及びその組立方法に関するものである。   The present invention relates to an automatic return electronic component that automatically returns to a predetermined return position from a position where a moving body such as an operation knob has moved, and an assembling method thereof.

従来、電子部品、例えばスライド式電子部品の中には、その操作つまみを移動することによって電気的出力(例えばスイッチオンオフ状態や抵抗値)を変化すると共に、前記操作つまみの移動を解除することでこの操作つまみが所定の復帰位置(例えば中立位置)に自動復帰して停止する構造の自動復帰型電子部品がある。   Conventionally, in an electronic component, for example, a slide-type electronic component, an electric output (for example, a switch on / off state or a resistance value) is changed by moving the operation knob, and the movement of the operation knob is canceled. There is an automatic return type electronic component having a structure in which the operation knob automatically returns to a predetermined return position (for example, neutral position) and stops.

この種の自動復帰型電子部品は、例えば特許文献1の図2に示すように、摺動子(60)を取り付けた摺動型物(50)に設けたコイルスプリング収納部(54)内にコイルスプリング(55)を圧縮して収納し、次にこの摺動型物(50)の上に下ケース(40)を被せるように組み込み、さらに下ケース(40)の下面にフレキシブル回路基板(70)と取付部材(80)とを設置して組み立てられる。コイルスプリング収納部(54)内に収納されたコイルスプリング(55)の両端は、コイルスプリング収納部(54)の係止部(56c,56d)と、下ケース(40)に設けた当接部(49c,49d)とに当接する。そして摺動型物(50)をスライド移動すれば、摺動子(60)がフレキシブル回路基板(70)上のスイッチパターン(71)上を摺動し、そのオンオフ出力が変化する。このときコイルスプリング(55)は一方の端部が一方の当接部(49c又は49d)に当接したまま、他方の端部が他方の係止部(56d又は56c)に押圧されて圧縮されており、摺動型物(50)を中立位置に自動復帰する弾発力が付勢されている。従って摺動型物(50)の移動を解除すると、摺動型物(50)は元の中立位置に自動的に移動して停止する。   For example, as shown in FIG. 2 of Patent Document 1, this type of automatic return type electronic component is provided in a coil spring housing portion (54) provided in a sliding type object (50) to which a slider (60) is attached. The coil spring (55) is compressed and accommodated, and then the lower case (40) is put on the sliding type object (50), and the flexible circuit board (70) is placed on the lower surface of the lower case (40). ) And the mounting member (80). Both ends of the coil spring (55) housed in the coil spring housing part (54) are connected to the latching parts (56c, 56d) of the coil spring housing part (54) and the contact part provided in the lower case (40). (49c, 49d). When the sliding object (50) is slid, the slider (60) slides on the switch pattern (71) on the flexible circuit board (70), and its on / off output changes. At this time, the coil spring (55) is compressed by being pressed by the other locking portion (56d or 56c) while the other end is in contact with the one contact portion (49c or 49d). The resilient force that automatically returns the sliding object (50) to the neutral position is urged. Accordingly, when the movement of the sliding object (50) is released, the sliding object (50) automatically moves to the original neutral position and stops.

しかしながら上記従来の自動復帰型電子部品においては前述のように、摺動型物(50)に設けたコイルスプリング収納部(54)内にコイルスプリング(55)を収納した上で、この摺動型物(50)の上に下ケース(40)を被せるように取り付ける際、コイルスプリング(55)の端部に下ケース(40)の当接部(49c又は49d)が当接するなどして、圧縮しているコイルスプリング(55)がコイルスプリング収納部(54)から飛び出してしまったり、コイルスプリング(55)の端部が損傷・変形したりして組み込み不良が生じる場合があった。またこの現象を防止するため、コイルスプリング(55)を収納した摺動型物(50)を下ケース(40)に組み込む際、コイルスプリング(55)の両端を別途用意した特殊な治具によって少し圧縮しておき、この状態で下ケース(40)に摺動型物(50)を組み込む方法もある。しかしながらこの方法の場合、特殊な治具が必要になるばかりか、下ケース(40)への摺動型物(50)の組込作業が煩雑になってしまう。
特開2007−53018号公報
However, in the conventional automatic return type electronic component, as described above, the coil spring (55) is accommodated in the coil spring accommodating portion (54) provided in the slide type object (50), and then this sliding type is used. When mounting the object (50) so that the lower case (40) is covered, the abutting part (49c or 49d) of the lower case (40) comes into contact with the end of the coil spring (55), and compression is performed. In some cases, the coil spring (55) is popped out of the coil spring housing part (54), or the end of the coil spring (55) is damaged or deformed, resulting in poor assembly. In order to prevent this phenomenon, when the sliding type object (50) containing the coil spring (55) is assembled into the lower case (40), the coil spring (55) is slightly affixed with a special jig separately prepared at both ends. There is also a method in which the sliding type object (50) is incorporated in the lower case (40) in a compressed state. However, in this method, not only a special jig is required, but also the work of assembling the sliding object (50) into the lower case (40) becomes complicated.

そして摺動子70を取り付けた移動体40を、ケース10の移動体収納部11内に収納する。この収納は、移動体40の両係止部挿入部51を設けた側の辺をケース10側に近づけるように傾けた状態で移動体40をケース10の移動体収納部11内に挿入してゆき、移動体40の係止部挿入部51にケース10の両係止部17を挿入しながら、徐々に移動体40の両係止部挿入部51を設けた反対側の辺を持ち上げてゆき、最終的に移動体40全体を移動体収納部11内に挿入する。このときの状態を図6に示す。同図に示すように、ケース10に移動体40を組み込んだ状態で弾発部材挿入口47は下面側に露出している。そしてケース10に対して移動体40を中立位置(即ち移動体40の両当接部53と、ケース10の両係止部17の対向する内側辺とを略一致させた状態)に位置させ、コイルバネ90を所定寸法圧縮した状態で外部(下方)から弾発部材挿入口47を通して移動体40の弾発部材収納部49に挿入・収納し、図7に示す状態とする。これによってコイルバネ90の両端がケース10の両係止部17と移動体40の両当接部53に係止された状態で、コイルバネ90は弾発部材収納部49内に保持される。   Then, the moving body 40 to which the slider 70 is attached is stored in the moving body storage portion 11 of the case 10. In this storage, the mobile body 40 is inserted into the mobile body storage portion 11 of the case 10 in a state where the side of the mobile body 40 on which the both locking portion insertion portions 51 are provided is inclined so as to approach the case 10 side. Then, while inserting the both locking portions 17 of the case 10 into the locking portion insertion portion 51 of the moving body 40, gradually lift the opposite side where the both locking portion insertion portions 51 of the moving body 40 are provided. Finally, the entire moving body 40 is inserted into the moving body storage unit 11. The state at this time is shown in FIG. As shown in the figure, the elastic member insertion port 47 is exposed on the lower surface side in a state in which the moving body 40 is incorporated in the case 10. Then, the moving body 40 is positioned in a neutral position with respect to the case 10 (that is, the state where both the abutting portions 53 of the moving body 40 and the opposite inner sides of the both locking portions 17 of the case 10 are substantially matched), With the coil spring 90 compressed to a predetermined size, the coil spring 90 is inserted and housed from the outside (below) through the resilient member insertion port 47 into the resilient member housing portion 49 of the moving body 40 to obtain the state shown in FIG. Accordingly, the coil spring 90 is held in the elastic member housing portion 49 in a state where both ends of the coil spring 90 are locked to both the locking portions 17 of the case 10 and both the contact portions 53 of the moving body 40.

即ちこの実施形態によれば、ケース10に移動体40を組み込んだ状態(ケース10に組み込んだ移動体40を取り外すこともできる仮組み込み状態)で移動体40の弾発部材収納部49に外部からコイルバネ90を挿入して収納できるので、コイルバネ90を収納した際に同時にコイルバネ90の両端をケース10の両係止部17に係止させることができる。従って従来のように予めコイルバネを収納した移動体をケースに組み込む際に生じるコイルバネの弾発部材収納部からの飛び出しや、組み込み不良の恐れが生じなくなる。即ちコイルバネ90を用いた自動復帰機構を有する自動復帰型電子部品1−1の組み立てが容易且つ確実に行なえるようになる。   That is, according to this embodiment, in the state where the moving body 40 is incorporated in the case 10 (temporarily assembled state in which the moving body 40 incorporated in the case 10 can be removed), the elastic member storing portion 49 of the moving body 40 is externally provided. Since the coil spring 90 can be inserted and stored, both ends of the coil spring 90 can be simultaneously locked to the both locking portions 17 of the case 10 when the coil spring 90 is stored. Accordingly, there is no possibility of the coil spring jumping out from the elastic member housing portion or the failure of the assembly that occurs when the moving body that stores the coil spring in advance is incorporated into the case as in the prior art. That is, the automatic return electronic component 1-1 having the automatic return mechanism using the coil spring 90 can be easily and reliably assembled.

そして前記ケース10の下面側にフレキシブル回路基板100と取付板130とを設置し、その際ケース10の各取付部15をフレキシブル回路基板100の各取付部挿通部105と取付板130の各挿通部131に挿入し、各取付部15の先端を取付板130の下面に折り曲げて各部材を一体化する。これによって自動復帰型電子部品1−1が完成する。   Then, the flexible circuit board 100 and the attachment plate 130 are installed on the lower surface side of the case 10, and each attachment portion 15 of the case 10 is replaced with each attachment portion insertion portion 105 of the flexible circuit board 100 and each insertion portion of the attachment plate 130. It inserts in 131, the front-end | tip of each attaching part 15 is bend | folded to the lower surface of the attachment board 130, and each member is integrated. Thus, the automatic return type electronic component 1-1 is completed.

このとき図3に示すようにコイルバネ90は弾発部材収納部49内に収納保持され、コイルバネ90の両端はケース10の両係止部17(対向する両内側辺)と移動体40の両当接部53に係止されている。そして移動体40の操作部41を操作することで移動体40をスライド移動方向Aにスライド移動すれば、摺動子70の一対のパターン当接部75が摺接パターン103上を摺動し、その電気的出力を変化する。移動体40を中立位置からスライド移動した際、図4に示すように、コイルバネ90の一方の端部(図4の左側の端部)はケース10の一方の係止部17に係止されたまま、他方の端部は移動体40の他方の当接部53によって押圧されて他方の係止部17から離れてゆき、コイルバネ90は圧縮される。これによって移動体40には元の復帰位置(中立位置)への自動復帰力が生じる。従って移動体40の移動を解除すれば、移動体40は元の中立位置に自動復帰する。   At this time, as shown in FIG. 3, the coil spring 90 is housed and held in the elastic member housing portion 49, and both ends of the coil spring 90 are both the two locking portions 17 (both opposite inner sides) of the case 10 and the movable body 40. Locked to the contact portion 53. Then, if the moving body 40 is slid in the slide movement direction A by operating the operation unit 41 of the moving body 40, the pair of pattern contact portions 75 of the slider 70 slide on the sliding contact pattern 103, Change its electrical output. When the moving body 40 is slid from the neutral position, one end (the left end in FIG. 4) of the coil spring 90 is locked to one locking portion 17 of the case 10 as shown in FIG. The other end portion is pressed by the other contact portion 53 of the moving body 40 and moves away from the other locking portion 17, and the coil spring 90 is compressed. As a result, the moving body 40 has an automatic return force to the original return position (neutral position). Therefore, when the movement of the moving body 40 is released, the moving body 40 automatically returns to the original neutral position.

以上説明したように自動復帰型電子部品1−1は、コイルバネ90と、規定のスライド移動方向Aに移動し、コイルバネ90を収納する弾発部材収納部49を有すると共に弾発部材収納部49のスライド移動方向Aに沿った両端にコイルバネ90の両端を当接する当接部53を設けた移動体40と、移動体40をスライド移動自在に組み込むと共に組み込んだ移動体40の両当接部53近傍位置においてコイルバネ90の両端を当接する係止部17を設けたケース10と、移動体40のスライド移動によって電気的出力を変化する摺動子70及び摺接パターン103からなる電気的機能部とを具備しており、弾発部材収納部49にコイルバネ90を収納してコイルバネ90の両端をケース10の両係止部17に係止させることで移動体40を移動した位置から復帰位置へ自動復帰させる構成となっている。そしてケース10に移動体40を組み込んだ状態で移動体40の弾発部材収納部49に外部からコイルバネ90を挿入する弾発部材挿入口47を設けることで、前述のようにコイルバネ90を弾発部材収納部49に収納した際に同時にコイルバネ90の両端をケース10の両係止部17に係止させることができ、従ってコイルバネ90の弾発部材収納部49からの飛び出しや、組み込み不良の恐れが生じなくなり、自動復帰型電子部品1−1の組み立てが容易且つ確実に行なえるようになる。またこの自動復帰型電子部品1−1の場合、弾発部材挿入口47を移動体40のケース10に覆われる反対側の面に設けたので、ケース10の上面を、移動体40の操作部41をケース10の上面から突出する等、他の用途に有効に利用でき、好適である。   As described above, the automatic return electronic component 1-1 includes the coil spring 90 and the elastic member storage portion 49 that moves in the specified slide movement direction A and stores the coil spring 90, and the elastic member storage portion 49 includes A moving body 40 provided with abutting portions 53 that abut both ends of the coil spring 90 at both ends along the slide movement direction A, and the vicinity of both abutting portions 53 of the moving body 40 in which the moving body 40 is slidably incorporated. The case 10 provided with the locking portion 17 that contacts both ends of the coil spring 90 at the position, and the electrical functional portion including the slider 70 and the sliding contact pattern 103 that change the electrical output by the sliding movement of the moving body 40. The moving body 40 is accommodated by housing the coil spring 90 in the elastic member housing portion 49 and locking both ends of the coil spring 90 to the both locking portions 17 of the case 10. And it has a configuration to automatically return from the dynamic position to the return position. In the state where the moving body 40 is incorporated in the case 10, the elastic member accommodating portion 49 of the moving body 40 is provided with the elastic member insertion port 47 for inserting the coil spring 90 from the outside. Both ends of the coil spring 90 can be simultaneously locked to the both locking portions 17 of the case 10 when the coil spring 90 is stored in the member storage portion 49, so that the coil spring 90 may jump out of the elastic member storage portion 49 or may be poorly assembled. As a result, the automatic return type electronic component 1-1 can be easily and reliably assembled. Further, in the case of the automatic return type electronic component 1-1, since the elastic member insertion port 47 is provided on the opposite surface of the moving body 40 covered by the case 10, the upper surface of the case 10 is placed on the operation unit of the moving body 40. 41 can protrude effectively from the upper surface of the case 10 and can be effectively used for other purposes.

またこの自動復帰型電子部品1−1においては、移動体40のスライド移動方向Aに対して左右両側の面の内の何れか一方の側面に、ケース10の係止部17を挿入してコイルバネ90の両端に係止させる係止部挿入部51を設けているので、ケース10の係止部17を移動体40の側面から挿入でき、自動復帰型電子部品1−1の薄型化が図れる。   Further, in this automatic return type electronic component 1-1, the engaging portion 17 of the case 10 is inserted into either one of the left and right sides of the moving body 40 in the slide movement direction A, and the coil spring is inserted. Since the locking portion insertion portions 51 to be locked at both ends of the 90 are provided, the locking portion 17 of the case 10 can be inserted from the side surface of the movable body 40, and the automatic return electronic component 1-1 can be thinned.

〔第2実施形態〕

[Second Embodiment]
FIG. 8 is an exploded perspective view of the automatic return electronic component 1-2 according to the second embodiment of the present invention as viewed from above, and FIG. 9 is an exploded perspective view as viewed from below. In the automatic return type electronic component 1-2 shown in these drawings, the same or corresponding parts as those in the automatic return type electronic component 1-1 according to the embodiment shown in FIGS. Note that matters other than those described below are the same as those in the embodiment shown in FIGS. As shown in these drawings, the automatic return type electronic component 1-2 also includes a case 10 that is a fixed member, a moving body 40 that is housed in the case 10, and an electrical functional unit that is attached to the moving body 40. These are a slider 70, a resilient member (hereinafter referred to as “coil spring”) 90 accommodated in a resilient member accommodating portion 49 provided on the moving body 40, and a fixed-side member installed on the lower surface side of the case 10. The circuit board (hereinafter, referred to as “flexible circuit board”) 100 and a mounting plate 130 that is a fixed member installed on the lower surface side of the flexible circuit board 100 are provided.

この実施形態において前記実施形態と相違する点は、ケース10と移動体40の形状のみである。即ちこの実施形態にかかるケース10において前記第1実施形態にかかるケース10と相違する点は、一対の係止部17を設けた側面の両係止部17の間の部分の側面を切り欠いて上面からの高さ寸法を短くしてその下側部分の空間を第1弾発部材挿入口19とした点のみである。   In this embodiment, the only difference from the previous embodiment is the shape of the case 10 and the moving body 40. That is, the case 10 according to this embodiment is different from the case 10 according to the first embodiment in that the side surface of the portion between the two locking portions 17 on the side surface provided with the pair of locking portions 17 is notched. The only difference is that the height dimension from the upper surface is shortened, and the space in the lower part is used as the first elastic member insertion port 19.

またこの実施形態にかかる移動体40において前記第1実施形態にかかる移動体40と相違する点は、第1実施形態で設けていた移動体40下面の弾発部材挿入口47をなくし、その代りに移動体40のスライド移動方向Aに平行な一方の側面(前記ケース10の係止部17に対向する側の側面)に第2弾発部材挿入口47−2を設けた点のみである(なお移動体40下面の弾発部材挿入口47はそのまま設けておいても良い)。第2弾発部材挿入口47−2はその内部の弾発部材収納部49に連通している。なお弾発部材収納部49の両端には第1実施形態と同様に当接部53が設けられている。また弾発部材挿入口47−2はその両側に設けられている一対の係止部挿入部51と連通し、一体のスリット状の穴となっている。   Further, the moving body 40 according to this embodiment differs from the moving body 40 according to the first embodiment in that the elastic member insertion port 47 provided on the lower surface of the moving body 40 provided in the first embodiment is eliminated, and instead. The second elastic member insertion port 47-2 is only provided on one side surface (the side surface facing the locking portion 17 of the case 10) parallel to the slide movement direction A of the movable body 40 ( Note that the elastic member insertion port 47 on the lower surface of the moving body 40 may be provided as it is). The second elastic member insertion port 47-2 communicates with the internal elastic member housing portion 49. In addition, the contact part 53 is provided in the both ends of the elastic member accommodating part 49 similarly to 1st Embodiment. The elastic member insertion port 47-2 communicates with a pair of locking portion insertion portions 51 provided on both sides thereof, and is an integral slit-like hole.

そして自動復帰型電子部品1−2を組み立てるには、第1実施形態と同様にまず予め移動体40に摺動子70を取り付ける。次に第1実施形態と同様に摺動子70を取り付けた移動体40を、ケース10の移動体収納部11内に収納する。このときの状態を図10に示す。同図に示すように、ケース10に移動体40を組み込んだ状態(仮組立状態)で第1弾発部材挿入口19の位置と第2弾発部材挿入口47−2の位置とが一致し、1つの弾発部材挿入口50が形成される。これによって弾発部材挿入口50は、移動体40のスライド移動方向Aに対して左右両側の面の内の何れか一つの面に設けられる。   In order to assemble the automatic return type electronic component 1-2, the slider 70 is first attached to the moving body 40 in advance as in the first embodiment. Next, the moving body 40 to which the slider 70 is attached is stored in the moving body storage portion 11 of the case 10 as in the first embodiment. The state at this time is shown in FIG. As shown in the figure, the position of the first projecting member insertion port 19 and the position of the second projecting member insertion port 47-2 coincide with each other when the moving body 40 is incorporated in the case 10 (temporary assembly state). One elastic member insertion port 50 is formed. Accordingly, the elastic member insertion port 50 is provided on any one of the left and right surfaces with respect to the slide movement direction A of the moving body 40.

そしてケース10に対して移動体40を中立位置に位置させ、所定寸法圧縮した状態のコイルバネ90を外部から弾発部材挿入口50を通して移動体40の弾発部材収納部49内に挿入・収納する。これによってコイルバネ90の両端がケース10の両係止部17と移動体40の両当接部53に係止された状態で、コイルバネ90は弾発部材収納部49に保持される。コイルバネ90を弾発部材挿入口50に挿入する際は、係止部17の厚み寸法が係止部挿入部51内部の上下寸法よりも小さいので、その寸法の違い分だけ移動体40を係止部17に対して下降することで第2弾発部材挿入口47−2の位置を下げ、これによって弾発部材挿入口50の高さ寸法を大きくした状態でコイルバネ90を挿入し、挿入後は移動体40を正規の位置まで上昇して第2弾発部材挿入口47−2の位置を上げ、これによって弾発部材挿入口50の高さ寸法を小さくしてコイルバネ90の外部への抜けを防止する。   Then, the movable body 40 is positioned at the neutral position with respect to the case 10, and the coil spring 90 in a state of being compressed by a predetermined size is inserted / stored from the outside into the resilient member housing portion 49 of the movable body 40 through the resilient member insertion port 50. . As a result, the coil spring 90 is held in the elastic member housing portion 49 in a state where both ends of the coil spring 90 are locked to both the locking portions 17 of the case 10 and both the contact portions 53 of the moving body 40. When the coil spring 90 is inserted into the resilient member insertion port 50, the thickness dimension of the latching portion 17 is smaller than the vertical dimension inside the latching portion insertion portion 51, so the movable body 40 is latched by the difference in dimension. The coil spring 90 is inserted in a state in which the height of the resilient member insertion port 50 is increased by lowering the position of the second resilient member insertion port 47-2 by being lowered with respect to the portion 17, and after the insertion, The movable body 40 is raised to the normal position to raise the position of the second elastic member insertion port 47-2, thereby reducing the height dimension of the elastic member insertion port 50 and removing the coil spring 90 to the outside. To prevent.

そしてこの実施形態の場合も、ケース10に移動体40を組み込んだ状態で移動体40の弾発部材収納部49に外部からコイルバネ90を挿入して収納できるので、コイルバネ90を収納した際に同時にコイルバネ90の両端をケース10の両係止部17に係止させることができる。従って従来のように予めコイルバネを収納した移動体をケースに組み込む際に生じるコイルバネの弾発部材収納部からの飛び出しや、組み込み不良の恐れが生じなくなる。即ちコイルバネ90を用いた自動復帰機構を有する自動復帰型電子部品1−2の組み立てが容易且つ確実に行なえるようになる。   Also in this embodiment, since the coil spring 90 can be inserted and stored from the outside in the elastic member storage portion 49 of the moving body 40 with the moving body 40 incorporated in the case 10, the coil spring 90 is simultaneously stored. Both ends of the coil spring 90 can be locked to both locking portions 17 of the case 10. Accordingly, there is no possibility of the coil spring jumping out from the elastic member housing portion or the failure of the assembly that occurs when the moving body that stores the coil spring in advance is incorporated into the case as in the prior art. That is, the automatic return electronic component 1-2 having the automatic return mechanism using the coil spring 90 can be easily and reliably assembled.

そして前記ケース10の下面側に第1実施形態の場合と同様にしてフレキシブル回路基板100と取付板130とを取り付けて各部材を一体化すれば、自動復帰型電子部品1−2が完成する。この自動復帰型電子部品1−2の動作は、第1実施形態の動作と同一なので、その説明は省略する。   If the flexible circuit board 100 and the mounting plate 130 are attached to the lower surface side of the case 10 in the same manner as in the first embodiment and the respective members are integrated, the automatic return type electronic component 1-2 is completed. Since the operation of the automatic return type electronic component 1-2 is the same as that of the first embodiment, the description thereof is omitted.

以上説明したように自動復帰型電子部品1−2は、コイルバネ90と、規定のスライド移動方向Aに移動し、コイルバネ90を収納する弾発部材収納部49を有すると共に弾発部材収納部49のスライド移動方向Aに沿った両端にコイルバネ90の両端を当接する当接部53を設けた移動体40と、移動体40をスライド移動自在に組み込むと共に組み込んだ移動体40の両当接部53近傍位置においてコイルバネ90の両端を当接する係止部17を設けたケース10と、移動体40のスライド移動によって電気的出力を変化する摺動子70及び摺接パターン103からなる電気的機能部とを具備しており、弾発部材収納部49にコイルバネ90を収納してコイルバネ90の両端をケース10の両係止部17に係止させることで移動体40を移動した位置から復帰位置へ自動復帰させる構成となっている。そしてケース10に移動体40を組み込んだ状態で移動体40の弾発部材収納部49に外部からコイルバネ90を挿入する弾発部材挿入口50(第1,第2弾発部材挿入口19,47−2)を設けることで、前述のようにコイルバネ90を弾発部材収納部49に収納した際に同時にコイルバネ90の両端をケース10の両係止部17(及び当接部53)に係止させることができ、従ってコイルバネ90の弾発部材収納部49からの飛び出しや、組み込み不良の恐れが生じなくなり、自動復帰型電子部品1−2の組み立てが容易且つ確実に行なえるようになる。またこの自動復帰型電子部品1−2の場合、弾発部材挿入口50を、移動体40のスライド移動方向Aに対して左右両側の面の内の何れか一つの面に設けたので、第1実施形態の場合と同様に、ケース10の上面を他の用途(例えば移動体40に設けた操作部41をケース10の上面から突出する等)に有効に利用でき、好適である。   As described above, the automatic return type electronic component 1-2 has the coil spring 90 and the elastic member storage portion 49 that moves in the predetermined sliding movement direction A and stores the coil spring 90, and the elastic member storage portion 49 includes A moving body 40 provided with abutting portions 53 that abut both ends of the coil spring 90 at both ends along the slide movement direction A, and the vicinity of both abutting portions 53 of the moving body 40 in which the moving body 40 is slidably incorporated. The case 10 provided with the locking portion 17 that contacts both ends of the coil spring 90 at the position, and the electrical functional portion including the slider 70 and the sliding contact pattern 103 that change the electrical output by the sliding movement of the moving body 40. The moving body 40 is accommodated by housing the coil spring 90 in the elastic member housing portion 49 and locking both ends of the coil spring 90 to the both locking portions 17 of the case 10. And it has a configuration to automatically return from the dynamic position to the return position. The elastic member insertion port 50 (first and second elastic member insertion ports 19 and 47 for inserting the coil spring 90 from the outside into the elastic member housing portion 49 of the movable body 40 in a state in which the movable body 40 is incorporated in the case 10. -2), when the coil spring 90 is housed in the elastic member housing portion 49 as described above, both ends of the coil spring 90 are simultaneously locked to the both locking portions 17 (and the contact portion 53) of the case 10. Therefore, there is no possibility of the coil spring 90 jumping out from the elastic member housing portion 49 and the possibility of poor assembly, and the automatic return electronic component 1-2 can be easily and reliably assembled. In the case of this automatic return type electronic component 1-2, the elastic member insertion port 50 is provided on any one of the left and right sides with respect to the slide movement direction A of the moving body 40. As in the case of the first embodiment, the upper surface of the case 10 can be effectively used for other purposes (for example, the operation unit 41 provided on the moving body 40 protrudes from the upper surface of the case 10).

またこの自動復帰型電子部品1−2においても、移動体40のスライド移動方向Aに対して左右両側の面の内の何れか一方の側面に、ケース10の係止部17を挿入してコイルバネ90の両端に係止させる係止部挿入部51を設けているので、自動復帰型電子部品1−2の薄型化が図れる。   Also in this automatic return type electronic component 1-2, a coil spring is formed by inserting the engaging portion 17 of the case 10 into either one of the left and right sides of the sliding movement direction A of the moving body 40. Since the locking portion insertion portions 51 to be locked at both ends of the 90 are provided, the automatic return electronic component 1-2 can be thinned.
