Description

本発明は、本体に対しリッド等の可動体を閉位置と開位置とに回動切り換える場合に好適な可動体用開閉装置に関する。   The present invention relates to a movable body opening / closing device suitable for rotating a movable body such as a lid between a closed position and an open position with respect to a main body.

図７は特許文献１のリッド用開閉装置を、（ａ）がリッドの閉位置で、（ｂ）がリッドの開位置で示している。この開閉装置１は、本体（フレーム）２に対し回動可能に枢支されて閉位置と開位置とに切り換えられるリッドＬと、リッドＬを閉位置と開位置との間のある回動角を境として閉方向又は開方向へ反転可能に付勢する捻りコイルばね９とを備えている。リッドＬは、支持用アーム３を有し、本体２に対しアーム３の先端側が枢軸４を介して枢支される。アーム３の先端側には、ダンパー６のピニオン７と噛み合うギア５が枢軸４を中心とした円弧状に設けられている。捻りコイルばね９は、中間のコイル部９ａと、コイル部９ａの各端から延出された両側の延出部９ｂ，９ｃとを有し、一方延出部９ｂがリッド側に係止され、他方延出部９ｃが本体側に係止されている。そして、リッドＬは、（ａ）の閉位置において、捩りコイルばね９が両延出部間の内角を拡大する向きの付勢力を発揮し、その付勢力により閉位置に保持されている。この状態から、リッドＬは開方向へ捻りコイルばね９の付勢力に抗して回動操作され、ある角度を超えると、（ｂ）に示されるように捩りコイルばね９の付勢力が反転し、それ以後は、捩りコイルばね９の付勢力により開位置へ回動される。以上のような開閉装置は、リッドが開位置又は閉位置から途中まで回動操作されると、後は閉方向又は開方向へ付勢力で回動切り換えられるため操作性に優れるとともに、リッドが閉位置と開位置で共に付勢されているためラッチ機構等の保持手段を省略できる。用途は、例えば、自動車のインストルメントパネルに設けられているグローブボックスにおけるリッドの開閉機構に採用されている（特開２００５−２６３２３７号公報の図５を参照）。   FIG. 7 shows the lid opening / closing device of Patent Document 1, wherein (a) shows the lid closed position and (b) shows the lid open position. The opening / closing device 1 is pivotally supported with respect to a main body (frame) 2 so as to be switched between a closed position and an open position, and a rotation angle between the lid L between the closed position and the open position. And a torsion coil spring 9 that is urged to be reversible in the closing direction or the opening direction. The lid L has a support arm 3, and the distal end side of the arm 3 is pivotally supported with respect to the main body 2 via a pivot 4. A gear 5 that meshes with the pinion 7 of the damper 6 is provided on the distal end side of the arm 3 in an arc shape centering on the pivot 4. The torsion coil spring 9 has an intermediate coil portion 9a and extending portions 9b and 9c on both sides extending from each end of the coil portion 9a, while the extending portion 9b is locked to the lid side, The other extension 9c is locked to the main body side. The lid L exhibits the urging force in the direction in which the torsion coil spring 9 expands the inner angle between the two extending portions at the closed position (a), and is held at the closed position by the urging force. From this state, the lid L is rotated in the opening direction against the urging force of the torsion coil spring 9, and when the angle exceeds a certain angle, the urging force of the torsion coil spring 9 is reversed as shown in FIG. Thereafter, it is rotated to the open position by the urging force of the torsion coil spring 9. The opening / closing device as described above is excellent in operability because the lid is rotated by an urging force in the closing direction or the opening direction when the lid is rotated from the open position or the closed position to the middle, and the lid is closed. Since both the position and the open position are urged, the holding means such as a latch mechanism can be omitted. The application is adopted, for example, in a lid opening / closing mechanism in a glove box provided in an instrument panel of an automobile (see FIG. 5 of JP-A-2005-263237).

特開２００１−３３６３号公報（図１と図３）JP 2001-3363 A (FIGS. 1 and 3)

上記特許文献１のような装置構造では、例えば、略Ｕ形の捻りコイルばね９を使用しているため付勢力が反転時に過大になったり、捻りコイルばね９が一方延出部９ｂをリッド側に係止し他方延出部９ｃを本体側に係止した状態で、略Ｕ形に配置されている関係で付勢方向を反転するときに他の部材と干渉して異音を発生し易くなる。この対策としては、捻りコイルばねに代えて直線形のコイルばね（引張りコイルばね）を使用し、コイルばねの一端をリッド側に係止し、他端を本体側に係止することも考えられる。しかし、その場合は、例えば、コイルばねの他端が固定されている関係で付勢力の強弱に欠け、例えば、反転後の付勢力（リッドに対する回転トルク）が小さくなる。   In the device structure as described in Patent Document 1, for example, since a substantially U-shaped torsion coil spring 9 is used, the urging force becomes excessive at the time of reversal, or the torsion coil spring 9 has one extension portion 9b on the lid side. In the state where the other extension portion 9c is locked to the main body side, when the urging direction is reversed due to the arrangement in a substantially U shape, it is easy to generate noise due to interference with other members. Become. As a countermeasure, it may be possible to use a linear coil spring (tensile coil spring) instead of the torsion coil spring, and to lock one end of the coil spring on the lid side and the other end on the main body side. . However, in that case, for example, the biasing force lacks because the other end of the coil spring is fixed, and, for example, the biasing force after rotation (rotational torque against the lid) becomes small.

本発明は、以上のような課題を解消して、可動体を閉位置と開位置との間のある回動角を境として閉方向又は開方向へ反転可能に付勢する付勢部材を備えた構造において、直線形のコイルばね（引張りコイルばね）を用いる場合にも付勢力の強弱を増大したり反転後の付勢力を大きく確保可能にすることを目的としている。   The present invention is provided with a biasing member that solves the above-described problems and biases the movable body so as to be reversible in the closing direction or the opening direction with a certain rotation angle between the closing position and the opening position as a boundary. The purpose of this structure is to increase the strength of the biasing force even when a linear coil spring (tensile coil spring) is used, or to ensure a large biasing force after reversal.

上記した目的を達成するため本発明は、本体に対し回動可能に枢支されて閉位置と開位置とに切り換えられる可動体と、前記可動体を閉位置と開位置との間のある回動角を境として閉方向又は開方向へ反転可能に付勢する付勢部材とを備えている可動体用開閉装置において、前記本体に対し揺動可能に枢支されて前記可動体に作動連結されるローターを有しているとともに、前記付勢部材の一端側を前記可動体に係止し、前記付勢部材の他端側を前記ローターに係止していることを特徴としている。なお、以上の本体はケース、ハウジング、車室内や機器類のパネル等を含む。また、可動体としてはリッド、蓋、扉、カバー等を含む。   In order to achieve the above-described object, the present invention provides a movable body that is pivotally supported with respect to a main body and is switched between a closed position and an open position, and the movable body is rotated between a closed position and an open position. A movable body opening / closing device comprising a biasing member that biases reversibly in a closing direction or an opening direction with a moving angle as a boundary, and is pivotally supported with respect to the main body and operatively connected to the movable body And the other end side of the biasing member is locked to the rotor. The main body includes a case, a housing, a vehicle interior, a panel of equipment, and the like. The movable body includes a lid, a lid, a door, a cover, and the like.

以上の本発明は、請求項２〜５のように具体化されることが好ましい。すなわち、
（ア）前記可動体は、支持用アームを有しているとともに、前記付勢部材が直線形のコイルばねからなり、前記アームに対し前記コイルばねの一端を係止している構成である（請求項２）。
（イ）前記可動体のアームに設けられたピンと、前記ローターに設けられて前記ピンと解除可能に嵌合する凹部とを有し、前記可動体を閉位置又は開位置からそれぞれ開方向又は閉方向へ回動する過程で前記ピンと前記凹部との嵌合、更に嵌合解除を伴って前記ローターを揺動するとともに、前記付勢部材の付勢方向を反転する構成である（請求項３）。
（ウ）前記可動体のアームが円板部及び該円板部の周囲に設けられた凹部と、前記ローターに設けられて前記凹部と解除可能に嵌合する凸部とを有し、前記可動体を閉位置又は開位置からそれぞれ開方向又は閉方向へ回動する場合に前記凹部と前記凸部との嵌合、更に嵌合解除を伴って前記ローターを揺動するとともに、前記付勢部材の付勢方向を反転する構成である（請求項４）。
（エ）請求項３又は４の可動体の開閉装置において、前記ローターは、前記本体に設けられた２カ所の規制部によりその揺動範囲が規制される構成である（請求項５）。 The present invention as described above is preferably embodied as in the second to fifth aspects. That is,
(A) The movable body has a support arm, the urging member is a linear coil spring, and one end of the coil spring is locked to the arm. Claim 2).
(A) a pin provided on the arm of the movable body and a recess provided on the rotor and releasably engaged with the pin, wherein the movable body is opened or closed from the closed position or the open position, respectively; In this process, the rotor is oscillated with the engagement between the pin and the recess and the release of the engagement, and the urging direction of the urging member is reversed.
(C) The arm of the movable body has a disk part and a concave part provided around the disk part, and a convex part provided in the rotor and releasably fitted to the concave part, When the body is rotated from the closed position or the open position in the opening direction or the closing direction, respectively, the rotor is swung with the engagement between the concave portion and the convex portion, and further, the engagement is released, and the biasing member The urging direction is reversed (claim 4).
(D) In the movable body opening and closing device according to claim 3 or 4, the swing range of the rotor is restricted by two restricting portions provided on the main body (claim 5).

請求項１と２の発明は、付勢部材が一端側を可動体に係止し他端側を揺動可能なローターに係止されているため、付勢部材の他端側を本体に対し位置固定している構造に比べ、例えば、請求項２のように直線形のコイルばねを用いる場合にも付勢力の強弱を増大したり、可動体を開位置や閉位置から回動したときに付勢部材の反転時期を早くしたり、反転後の付勢力を大きくするなど改善して操作感を向上できるようにする。また、請求項３と４の発明はローターが可動体に作動連結される構造として、図１〜図３の形態及び図４〜図６の形態を特定することで明瞭化し、請求項５の発明はローターの揺動範囲が本体側の規制部により規制される点を明瞭化したことに意義がある。   According to the first and second aspects of the present invention, since the biasing member is locked to the movable body with one end side locked to the movable body and the other end side can be swung, the other end side of the biasing member is fixed to the main body. Compared to the structure in which the position is fixed, for example, even when a linear coil spring is used as in claim 2, the urging force is increased or decreased or the movable body is rotated from the open position or the closed position. The feeling of operation can be improved by improving the urging force of the urging member earlier or by increasing the urging force after the inverting.

Is meaningful in that it clarifies that the swing range of the rotor is regulated by the regulating part on the main body side.

以下、本発明形態として、図１〜図３に示した第１形態と、図４〜図６に示した第２形態について説明する。この説明では、各形態に共通した全体の構造、各形態毎の要部構造及び作動の順に詳述する。なお、各形態では同じ部材か類似する部材に同一符号を付している。   Hereinafter, the first embodiment shown in FIGS. 1 to 3 and the second embodiment shown in FIGS. 4 to 6 will be described as embodiments of the present invention. In this description, the entire structure common to each form, the main part structure for each form, and operation will be described in detail. In addition, in each form, the same code | symbol is attached | subjected to the same member or a similar member.

（全体の構造）各形態例の開閉装置は、 本体１に対しリッド２を本体１の開口をほぼ全開する開位置と、開口を塞ぐ閉位置とに回動切り換える構成であり、リッド２を閉位置と開位置との間のある回動角を境として閉方向又は開方向へ反転可能に付勢する付勢部材として直線形のコイルばね（引張りコイルばね）３を有している。ここで、本体１は、概略形状が前開口した矩形立体からなり、背面１０及び両側面１１並びに上下面１２，１３などで区画されている。リッド２は、閉位置でケース本体１の前開口を塞ぐ大きさの矩形板部２０と、板部２０の左右側部にそれぞれ取り付けられたアーム２１，２１とを有している。各アーム２１は自由端側が円板部２２又は２３に形成されている。そして、リッド２は、各アーム２１がケース本体１の対応側面１１にそれぞれ配置され、円板部２２又は２３の中心がボルト等の枢軸６を介して枢支されることで回動可能に取り付けられている。本体１の各側面１１には、アーム側の円板部２２又は２３に作動連結されるローター４又は５がボルト等の枢軸７を介して揺動可能に枢支されている。コイルばね３は、一端３ａがリッド側の円板部２２又は２３に係止され、他端５ｂがローター４又は５に係止されている。 (Whole structure) The opening / closing device of each embodiment is configured to rotate and switch the lid 2 between the main body 1 between an open position where the opening of the main body 1 is substantially fully opened and a closed position where the opening is closed. A linear coil spring (tensile coil spring) 3 is provided as an urging member for urging reversible in the closing direction or the opening direction with a certain rotation angle between the position and the open position as a boundary. Here, the main body 1 is formed of a rectangular solid whose front shape is opened in front, and is partitioned by a back surface 10, both side surfaces 11, top and bottom surfaces 12, 13 and the like. The lid 2 has a rectangular plate portion 20 that is large enough to close the front opening of the case body 1 in the closed position, and arms 21 and 21 that are respectively attached to the left and right side portions of the plate portion 20. Each arm 21 is formed on the disk portion 22 or 23 on the free end side. The lid 2 is attached so that each arm 21 is arranged on the corresponding side surface 11 of the case body 1 and the center of the disk portion 22 or 23 is pivotally supported via a pivot 6 such as a bolt. It has been. On each side surface 11 of the main body 1, a rotor 4 or 5 that is operatively connected to the arm-side disk portion 22 or 23 is pivotally supported via a pivot 7 such as a bolt. One end 3 a of the coil spring 3 is locked to the disk portion 22 or 23 on the lid side, and the other end 5 b is locked to the rotor 4 or 5.

なお、発明対象の開閉装置は色々な分野に適用可能である。一例としては、上記したように、自動車のインストルメントパネルに設けられているグローブボックスを本体とし、該グローブボックス用リッドを可動体とした構成である。   Note that the opening / closing device of the invention is applicable to various fields. As an example, as described above, a glove box provided on an instrument panel of an automobile is a main body, and the glove box lid is a movable body.

（第１形態の要部）図１〜図３において、円板部２２は、アーム２１側である上側半体２２ａに対し中心部を含む下側半体２２ｂが一段低い段差つまり薄く形成されている。そして、上側半体２２ａには、コイルばね３の一端３ａがねじ等の止め具８を介して係止されている。下側半体２２ｂには外周よりにピン２４が突設されている。 (Main part of the first embodiment) In FIGS. 1 to 3, the disk part 22 is formed such that the lower half 22b including the center part is lower by one step than the upper half 22a on the arm 21 side, that is, is thin. Yes. Then, one end 3a of the coil spring 3 is locked to the upper half 22a via a stopper 8 such as a screw. A pin 24 protrudes from the outer periphery of the lower half 22b.

ローター４は、概略円盤状をなしているとともに、周囲の一部にピン２４と解除可能に嵌合する凹部４０を形成している。この凹部４０は、ローター周囲に突出部４１を設け、該突出部４１に対し外周側を底辺とし、ローター中心側を頂点とする概略三角形状の切欠部４２を形成し、該切欠部４２の狭くなった頂部に位置している。また、ローター４は、本体側面１１に対向する内端面において、中心（軸孔）側が一段厚く形成されることで、突出部４１が円板部２２の一段低い段差となっている下側半体２２ｂ上に配置可能となる。   The rotor 4 has a substantially disk shape, and a recess 40 that is releasably fitted to the pin 24 is formed in a part of the periphery. The recess 40 is provided with a protrusion 41 around the rotor, and forms a substantially triangular notch 42 with the outer peripheral side as a base and the rotor center side as a vertex with respect to the protrusion 41. Located at the top. Further, the rotor 4 is formed on the inner end surface facing the side surface 11 of the main body so that the center (shaft hole) side is formed one step thicker so that the protruding portion 41 is a step that is one step lower than the disc portion 22. It becomes possible to arrange on 22b.

以上のローター４は、本体側面１１に対し枢軸７により揺動可能に枢支される。その後、コイルばね３の他端３ｂは、ローター４の外端面のうち、凹部４０と最も離れる側、つまり枢軸６と枢軸７とを結ぶほぼ延長線上にねじ等の止め具９を介して係止されている。また、ローター４は、本体側面１１に設けられた２カ所の規制部１５，１６によりその揺動範囲が規制される。各規制部１５，１６は、枢軸６と枢軸７とを結ぶ線上を横切る枢軸６を中心とした円弧上の位置で、かつ枢軸６と枢軸７とを結ぶ線に対し上下対称の位置に設けられている。   The above rotor 4 is pivotally supported by the pivot 7 with respect to the main body side surface 11. Thereafter, the other end 3 b of the coil spring 3 is locked via a stopper 9 such as a screw on the outermost end surface of the rotor 4 on the side farthest from the recess 40, that is, substantially on the extension line connecting the pivot 6 and the pivot 7. Has been. Further, the swing range of the rotor 4 is restricted by two restricting portions 15 and 16 provided on the side surface 11 of the main body. Each of the restricting portions 15 and 16 is provided at a position on an arc centering on the pivot 6 that crosses the line connecting the pivot 6 and the pivot 7, and at a position that is vertically symmetric with respect to a line connecting the pivot 6 and the pivot 7. ing.

（作動）以上の開閉装置は、特に、コイルばね３がその反転時期及び付勢力の大きさ等に自由度を得られるようにするため、アーム２１に設けられたピン２４と、ローター４に設けられた凹部４０とがリッド２を閉位置又は開位置からそれぞれ開方向又は閉方向へ回動する過程で嵌合し、更に嵌合解除を伴ってローター４を揺動し、コイルばね３の付勢方向を反転するようにしたものである。 (Operation) The above opening / closing device is provided in the rotor 24 and the pin 24 provided in the arm 21 so that the coil spring 3 can obtain a degree of freedom in the reversal timing, the magnitude of the biasing force, and the like. The recessed portion 40 is fitted in the process of rotating the lid 2 in the opening direction or the closing direction from the closed position or the open position, respectively, and further, the rotor 4 is swung with the release of the fitting, and the coil spring 3 is attached. The power direction is reversed.

すなわち、図１（ａ）はリッド２が閉位置に配置された状態である。この状態では、ローター４が上側の規制部１５に突出部４１の対応側面を当接して揺動規制され、リッド２がコイルばね３の付勢力を受けて閉位置に保持されている。なお、ピン２４は切欠部３２の対応辺部に非接触となっている。   That is, FIG. 1A shows a state in which the lid 2 is disposed at the closed position. In this state, the rotor 4 is controlled to swing by contacting the corresponding side surface of the protruding portion 41 with the upper restricting portion 15, and the lid 2 is held in the closed position by receiving the urging force of the coil spring 3. The pin 24 is not in contact with the corresponding side portion of the notch 32.

図１（ｂ）はリッド２が閉位置から開方向へ回動操作された初期段階を示している。この回動操作では、リッド２がコイルばね３の付勢力に抗して（付勢力を増大しながら）回動され、ピン２４がその回動に伴って凹部４０に近づく。図２（ａ）はリッド２が更に開方向へ回動操作されてピン２４と凹部４０とが嵌合した直前を示している。ローター４は、ピン２４が凹部４０と嵌合すると同時に、逆時計回りに揺動されて突出部４１を両規制部１５，１６に対し非接触の状態となる。   FIG. 1B shows an initial stage in which the lid 2 is rotated from the closed position to the open direction. In this rotation operation, the lid 2 is rotated against the urging force of the coil spring 3 (while increasing the urging force), and the pin 24 approaches the recess 40 as the rotation occurs. FIG. 2A shows the state immediately before the lid 2 is further rotated in the opening direction and the pin 24 and the recess 40 are fitted. The rotor 4 is swung counterclockwise at the same time that the pin 24 engages with the recess 40, and the protruding portion 41 is not in contact with both the restricting portions 15 and 16.

図２（ｂ）はリッド２が更に開方向へ回動されてピン２４が凹部４０から完全に嵌合解除された状態を示している。ローター４は、嵌合解除と同時に下側の規制部１６に突出部４１の対応側面を当接して揺動規制される。リッド２は、嵌合解除と同時にコイルばね３に蓄えられた付勢力によって図３（ａ）の開位置まで自動的に回動される。そして、リッド２は、開位置においてコイルばね３の付勢力を受けて保持される。なお、ピン２４は、リッド２の回動に伴って凹部４０から離れるべく切欠部４２の対応下辺部に沿って非接触で移動される。   FIG. 2B shows a state in which the lid 2 is further rotated in the opening direction and the pin 24 is completely released from the recess 40. The rotor 4 is restricted from swinging when the corresponding side surface of the protrusion 41 is brought into contact with the lower restricting portion 16 simultaneously with the release of the fitting. The lid 2 is automatically rotated to the open position in FIG. 3A by the urging force stored in the coil spring 3 simultaneously with the release of the fitting. The lid 2 is held by receiving the urging force of the coil spring 3 in the open position. The pin 24 is moved in a non-contact manner along the corresponding lower side portion of the notch portion 42 so as to be separated from the concave portion 40 as the lid 2 rotates.

これに対し、図３（ｂ）はリッド２が開位置から閉方向へ回動操作されて、ピン２４がその回動に伴って図２（ｂ）と同様に凹部４０に嵌合された後、該嵌合解除される直前を示している。リッド２は、この係合解除状態から、ローター４が揺動されて上側の規制部１５に突出部４１の対応側面を当接して揺動規制されるとともに、コイルばね３の付勢力で閉位置まで自動的に回動される。   On the other hand, in FIG. 3B, the lid 2 is rotated from the open position to the closing direction, and the pin 24 is fitted in the recess 40 in the same manner as in FIG. , Just before the mating is released. From this disengaged state, the lid 2 is controlled to swing while the rotor 4 is swung so that the upper restricting portion 15 abuts the corresponding side surface of the protruding portion 41, and the lid 2 is closed by the biasing force of the coil spring 3. Is automatically rotated.

（第２形態の要部）図４〜図６において、円板部２３には凹部２５，２６が外周の２カ所に所定角度を保って形成されている。そして、円板部２３には、コイルばね３の一端３ａがねじ等の止め具８を介して係止されている。これに対し、ローター５は、概略円盤状の基体５０と、基体５０の外周に突出されている腕部５１とからなる。基体５０には凸部５２が外周に突設されている。凸部５２は、円板部２３の凹部２５，２６に選択的かつ解除可能に嵌合される。 (Main part of the second embodiment) In FIGS. 4 to 6, the disk part 23 is formed with recesses 25 and 26 at two positions on the outer periphery at a predetermined angle. Then, one end 3a of the coil spring 3 is locked to the disc portion 23 via a stopper 8 such as a screw. On the other hand, the rotor 5 includes a substantially disc-shaped base body 50 and arm portions 51 that protrude from the outer periphery of the base body 50. A convex portion 52 is provided on the outer periphery of the base 50. The convex portion 52 is selectively and releasably fitted into the concave portions 25 and 26 of the disc portion 23.

以上のローター５は、基体５０が本体側面１１に対し枢軸７により揺動可能に枢支される。その後、コイルばね３の他端３ｂは、ローター５の腕部５１にねじ等の止め具９を介して係止されている。また、ローター５は、本体側面１１に設けられた２カ所の規制部１７，１８によりその揺動範囲が規制される。各規制部１７，１８は、枢軸６と枢軸７とを結ぶ線上を横切る枢軸７を中心とした円弧上の位置で、かつ枢軸６と枢軸７とを結ぶ線に対し上下対称の位置に設けられている。   The rotor 5 is pivotally supported by the pivot 7 so that the base body 50 can swing with respect to the main body side surface 11. Thereafter, the other end 3 b of the coil spring 3 is locked to the arm portion 51 of the rotor 5 via a stopper 9 such as a screw. Further, the swing range of the rotor 5 is restricted by two restricting portions 17 and 18 provided on the side surface 11 of the main body. Each restricting portion 17, 18 is provided at a position on an arc centering on the pivot 7 that crosses the line connecting the pivot 6 and the pivot 7, and at a position vertically symmetrical with respect to a line connecting the pivot 6 and the pivot 7. ing.

（作動）以上の開閉装置は、特に、コイルばね３がその反転時期及び付勢力の大きさ等に自由度を得られるようにするため、アーム２１に設けられた凹部２５，２６と、ローター５に設けられた凸部５２とがリッド２を閉位置又は開位置からそれぞれ開方向又は閉方向へ回動する場合に凹部２５，２６の一方と凸部５２との嵌合、更に嵌合解除を伴ってローター５を揺動するとともに、コイルばね３の付勢方向を反転するようにしたものである。 (Operation) In the above opening / closing apparatus, in particular, the coil spring 3 is provided with the recesses 25 and 26 provided in the arm 21 and the rotor 5 so that the coil spring 3 can obtain a degree of freedom in the reversal timing, the magnitude of the biasing force, and the like. When the lid 52 rotates the lid 2 in the opening direction or the closing direction from the closed position or the open position, respectively, the fitting of one of the recesses 25 and 26 and the protruding part 52 is further released. Accordingly, the rotor 5 is swung, and the urging direction of the coil spring 3 is reversed.

すなわち、図４（ａ）はリッド２が閉位置に配置された状態である。この状態では、ローター５が下側の規制部１８に腕部５１の対応側面を当接して揺動規制され、リッド２がコイルばね３の付勢力を受けて閉位置に保持されている。なお、凸部５２は凹部２６の上内端部に嵌合している。   That is, FIG. 4A shows a state in which the lid 2 is disposed at the closed position. In this state, the rotor 5 is controlled to swing by contacting the corresponding side surface of the arm portion 51 with the lower regulating portion 18, and the lid 2 is held in the closed position by receiving the urging force of the coil spring 3. The convex portion 52 is fitted to the upper inner end portion of the concave portion 26.

図４（ｂ）はリッド２が閉位置から開方向へ回動操作された初期段階を示している。この回動操作では、凸部５２と凹部２６との嵌合を保って、リッド２がコイルばね３の付勢力に抗して（付勢力を増大しながら）回動されるとともに、ローター５がリッド２の回動と連動して逆時計回りに揺動される。この結果、腕部５１は下側の規制部１８から離れる。   FIG. 4B shows an initial stage in which the lid 2 is rotated from the closed position to the open direction. In this turning operation, the lid 2 is rotated against the urging force of the coil spring 3 (while increasing the urging force) while keeping the fitting of the convex portion 52 and the concave portion 26, and the rotor 5 is rotated. It is swung counterclockwise in conjunction with the rotation of the lid 2. As a result, the arm portion 51 is separated from the lower regulating portion 18.

図５（ａ）はリッド２が更に開方向へ回動操作されて、ローター５が上側の規制部１７に腕部５１の対応側面を当接して揺動規制されるとともに、凸部５２が凹部２６から嵌合解除した直前を示している。リッド２は、この嵌合解除と同時にコイルばね３に蓄えられた付勢力によって図５（ｂ）の開位置まで自動的に回動される。そして、リッド２は、開位置においてコイルばね３の付勢力を受けて保持される。なお、凸部５２は、リッド２の回動に伴って次の凹部２５と対向する位置まで移動される。   In FIG. 5A, the lid 2 is further rotated in the opening direction so that the rotor 5 is restricted from swinging by contacting the corresponding side surface of the arm 51 to the upper restricting portion 17, and the convex portion 52 is recessed. 26 shows a state immediately before the mating is released from 26. The lid 2 is automatically rotated to the open position in FIG. 5B by the urging force stored in the coil spring 3 simultaneously with the release of the fitting. The lid 2 is held by receiving the urging force of the coil spring 3 in the open position. The convex portion 52 is moved to a position facing the next concave portion 25 as the lid 2 rotates.

これに対し、図６（ａ）はリッド２が開位置から閉方向へ回動操作されて、ローター５が凸部５２を凹部２５の下内端部に嵌合した状態で時計回りに若干回動された状態である。図６（ｂ）はリッド２が更に閉方向へ回動操作されて、ローター５が下側の規制部１８に腕部５１の対応側面を当接して揺動規制されるとともに、凸部５２が凹部２５から嵌合解除した直前を示している。リッド２は、この嵌合解除から更に若干回動されると、以後はコイルばね３に蓄えられた付勢力によって図４（ａ）の閉位置まで自動的に回動される。そして、リッド２は閉位置においてコイルばね３の付勢力で保持される。   On the other hand, in FIG. 6A, the lid 2 is rotated from the open position to the closing direction, and the rotor 5 is slightly rotated clockwise with the convex portion 52 fitted to the lower inner end portion of the concave portion 25. It has been moved. In FIG. 6B, the lid 2 is further rotated in the closing direction so that the rotor 5 is restricted from swinging by contacting the corresponding side surface of the arm 51 to the lower restricting portion 18, and the convex portion 52 is A state immediately before the fitting is released from the recess 25 is shown. When the lid 2 is further rotated slightly after the fitting is released, thereafter, the lid 2 is automatically rotated to the closed position shown in FIG. 4A by the urging force stored in the coil spring 3. The lid 2 is held by the biasing force of the coil spring 3 in the closed position.
