本発明は、螺旋状のコイル部とこのコイル部の両端部から接線方向に延びる２つの腕部とを有するねじりばねを２つの部材間に取り付ける構造に関する。 The present invention relates to a structure in which a torsion spring having a helical coil portion and two arm portions extending tangentially from both ends of the coil portion is attached between two members.

従来、２つの部材間にねじりばねを架設することで、その操作性を向上させるようにしたものがある。具体的には、開閉ドアや開閉蓋においては、これらを支持する部材との間にねじりばねが架設されることにより、これらドアまたは蓋が開く方向や閉じる方向に付勢されるようにした構造が採用されている。 Conventionally, there is one in which a torsion spring is installed between two members to improve its operability. Specifically, in the open / close door and the open / close lid, a structure in which a torsion spring is installed between the open / close door and the member that supports the open / close door and the door or the cover is urged in the opening direction or the closing direction. Is adopted.

例えば、特許文献１に記載される車両用灰皿は、上部が開口する灰皿のアウターケースと、このアウターケースに取り付けられた支持軸に対して回動してアウターケースの開口を開閉するリッドとを備えている。そして、このリッドに形成される装着孔とアウターケースに形成される装着軸との間にコイルスプリング（ねじりばね）が架設されており、これによりこのリッドは開く方向にも閉じる方向にも付勢されるように構成されている。 For example, an ashtray for a vehicle described in Patent Document 1 includes an outer case of an ashtray having an upper opening, and a lid that rotates with respect to a support shaft attached to the outer case to open and close the opening of the outer case. I have. A coil spring (torsion spring) is installed between the mounting hole formed in the lid and the mounting shaft formed in the outer case, so that the lid is biased in both the opening direction and the closing direction. It is configured to be.

図７は、このコイルスプリング１００とアウターケース１１０における装着軸１１５の周辺の構成とを示している。図７に示すように、このコイルスプリング１００は、針金状のばね材がコイル状に巻かれてなるコイル部１０１と、このコイル部１０１の一端から接線方向に引き出された第１の腕部１０２と、同コイル部１０１の他端から接線方向に引き出された第２の腕部１０３とを備え、全体として「Ｖ」字状に形成されている。また、第２の腕部１０３の端部には、リング部１０５が形成されるとともに、アウターケース１１０にはこのリング部１０５が遊嵌される装着軸１１５が形成されている。さらに、アウターケース１１０には、この装着軸１１５に遊嵌されたリング部１０５が付勢された時に係合する係合溝１１６が形成されている。このような構成により、このコイルスプリング１００は、第１の腕部１０２の端部がリッドの装着孔に係止された状態で、第２の腕部のリング部１０５を装着軸１１５に遊嵌させると、リング部１０５が係合溝１１６に係合して抜け止めされるようになっている。
特開２００３−２４０３９号公報 FIG. 7 shows the coil spring 100 and the configuration around the mounting shaft 115 in the outer case 110. As shown in FIG. 7, the coil spring 100 includes a coil portion 101 in which a wire-like spring material is wound in a coil shape, and a first arm portion 102 that is drawn tangentially from one end of the coil portion 101. And a second arm portion 103 drawn in a tangential direction from the other end of the coil portion 101, and is formed in a “V” shape as a whole. In addition, a ring portion 105 is formed at the end of the second arm portion 103, and a mounting shaft 115 on which the ring portion 105 is loosely fitted is formed in the outer case 110. Further, the outer case 110 is formed with an engaging groove 116 that engages when the ring portion 105 loosely fitted to the mounting shaft 115 is urged. With this configuration, the coil spring 100 is loosely fitted to the mounting shaft 115 with the ring portion 105 of the second arm portion in a state where the end portion of the first arm portion 102 is locked in the mounting hole of the lid. As a result, the ring portion 105 is engaged with the engagement groove 116 to be prevented from coming off.

ところで、上記特許文献１に記載の車両用灰皿において、第２の腕部１０３のリング部１０５を装着軸１１５と遊嵌させる際には、このコイルスプリング１００において、第１の腕部１０２と第２の腕部１０３とがなす「Ｖ」字が閉じられるように、コイル部１０１を中心として第２の腕部１０３を回動させる。そして、この状態で、コイルスプリング１００の第２の腕部１０３のリング部１０５がアウターケース１１０側に押し付けられる。つまり、第２の腕部１０３のリング部１０５を、コイルスプリング１００の「Ｖ」字の開閉方向とコイル部１０１の軸方向との２方向においてその位置を規制しながら装着軸１１５に遊嵌させなければならず、その作業性に問題を残すものとなっている。 By the way, in the vehicle ashtray described in Patent Document 1, when the ring portion 105 of the second arm portion 103 is loosely fitted to the mounting shaft 115, the coil arm 100 has the first arm portion 102 and the second ashtray. The second arm portion 103 is rotated around the coil portion 101 so that the “V” shape formed by the second arm portion 103 is closed. In this state, the ring portion 105 of the second arm portion 103 of the coil spring 100 is pressed against the outer case 110 side. That is, the ring portion 105 of the second arm portion 103 is loosely fitted to the mounting shaft 115 while restricting its position in the two directions of the “V” -shaped opening / closing direction of the coil spring 100 and the axial direction of the coil portion 101. It has to leave a problem in its workability.

本発明は、こうした実情に鑑みてなされたものであり、その目的は、第１の部材と第２の部材との間でねじりばねを架設するにあたり、このねじりばねを容易に取り付けることができるねじりばねの取り付け構造を提供することにある。 The present invention has been made in view of such circumstances, and its purpose is to provide a torsion that can be easily attached to the torsion spring when the torsion spring is installed between the first member and the second member. It is to provide a spring mounting structure.

上記の目的を達成するために、請求項１に記載の発明は、螺旋状のコイル部と、該コイル部の一端から接線方向に延びる第１の腕部と、前記コイル部の他端から接線方向に延びるとともに端部が前記コイル部の略軸線方向に屈曲する第２の腕部とを有するねじりばねと、前記第１の腕部の端部を回動可能に係止する係止部を有する第１の部材と、前記第１の腕部の端部が前記係止された状態において、前記第２の腕部の端部と遊嵌して前記コイル部を中心とした前記第２の腕部の回動を規制する切り欠き部を有する第２の部材と、前記第１の腕部の端部が前記係止された状態で前記第２の腕部の端部を前記切り欠き部に遊嵌させる際に、前記第２の腕部の端部が前記コイル部の軸線方向の一方に変位することを規制する第１の規制面と、前記切り欠き部の入口から延設されて前記コイル部を中心とした前記第２の腕部の一方向の回動を規制する第２の規制面とを有するガイド部とを備えていることを要旨とする。 In order to achieve the above object, the invention according to claim 1 includes a spiral coil portion, a first arm portion extending in a tangential direction from one end of the coil portion, and a tangent line from the other end of the coil portion. A torsion spring having a second arm portion extending in a direction and having an end portion bent in a substantially axial direction of the coil portion, and a locking portion for rotatably locking the end portion of the first arm portion. In the state where the first member having the end portion of the first arm portion is locked, the second member centering on the coil portion by loosely fitting with the end portion of the second arm portion. A second member having a notch for restricting the rotation of the arm, and the end of the second arm in the state where the end of the first arm is locked. A first restricting surface that restricts the end of the second arm portion from being displaced in one of the axial directions of the coil portion when loosely fitting to the coil portion; And a guide portion that extends from the entrance of the notch portion and has a second restriction surface that restricts rotation of the second arm portion in one direction around the coil portion. And

上記の構成では、第１の腕部の端部が係止部に係止された状態で、第２の腕部をガイド部の第１の規制面と当接させることにより、第２の腕部の端部コイル部の軸線方向の一方に変位することを規制し、このコイル部の軸線方向において第２の腕部の端部を切り欠き部に対して位置決めする。また、第２の腕部の端部を、ガイド部の第２の規制面と当接させることにより、コイル部を中心とした第２の腕部の一方向の回動を規制する。そして、第２の腕部を第１及び第２の各規制面に当接させた状態で切り欠き部に向ってスライドさせると、コイル部を中心とした第２の腕部の一方向の回動が第２の規制面によって規制された状態で、コイル部と第２の腕部とが相対回動する。そして、切り欠き部の入口から延設された第２の規制面によって第２の腕部の端部が切り欠き部の入口に導かれた後、コイル部が第２の腕部を回動させる復元力によって第２の腕部の端部が切り欠き部の位置する方向に付勢され、これにより第２の腕部の端部と切り欠き部とが遊嵌することとなる。つまり、ねじりばねを取り付ける際に、第２の腕部をガイド部の第１及び第２の各規制面に当接させれば、このねじりばねに対して第２の腕部を切り欠き部に向ってスライドさせる一方向の力のみを作用させるだけで、第２の腕部の端部と切り欠き部とが遊嵌する。 In the above configuration, the second arm is brought into contact with the first restriction surface of the guide portion in a state where the end portion of the first arm portion is locked to the locking portion. Displacement in one axial direction of the end coil portion of the portion is restricted, and the end portion of the second arm portion is positioned with respect to the notch portion in the axial direction of the coil portion. Further, the end of the second arm portion is brought into contact with the second restriction surface of the guide portion, thereby restricting the one-way rotation of the second arm portion around the coil portion. Then, when the second arm portion is slid toward the notch in a state where the second arm portion is in contact with the first and second regulating surfaces, the rotation of the second arm portion in one direction around the coil portion is performed. In a state where the movement is restricted by the second restriction surface, the coil portion and the second arm portion rotate relative to each other. And after the edge part of a 2nd arm part is guide | induced to the entrance of a notch part by the 2nd control surface extended from the entrance of a notch part, a coil part rotates a 2nd arm part. The end of the second arm is biased in the direction in which the notch is located by the restoring force, and the end of the second arm and the notch are loosely fitted. In other words, when the torsion spring is attached, if the second arm portion is brought into contact with the first and second regulating surfaces of the guide portion, the second arm portion becomes a notch portion with respect to the torsion spring. The end of the second arm and the notch are loosely fitted only by applying a force in one direction that slides in the direction.

このようにして、ねじりばねを第１の部材の係止部に係止させた状態で、第２の腕部の端部の２方向の位置規制を容易に行うことができるため、第２の腕部を上記各規制面に当接させてスライドさせるといった簡素な方法で、第２の腕部の端部と切り欠き部とを容易に遊嵌させることができる。 In this manner, the position of the end of the second arm can be easily regulated in the two directions with the torsion spring locked to the locking portion of the first member. The end portion of the second arm portion and the notch portion can be easily loosely fitted by a simple method in which the arm portion is brought into contact with the respective regulating surfaces and slid.

請求項２に記載の発明は、請求項１に記載の発明において、前記ガイド部は、前記第２の腕部の端部と前記切り欠き部とが遊嵌する状態において、前記コイル部を中心とした前記第２の腕部の一方向の回動を規制する第３の規制面を備えていることを要旨とする。 According to a second aspect of the present invention, in the first aspect of the present invention, the guide portion is centered on the coil portion in a state in which the end portion of the second arm portion and the notch portion are loosely fitted. The gist of the present invention is that a third restricting surface for restricting the rotation of the second arm portion in one direction is provided.

上記の構成では、第３の規制面によって、前記第２の腕部の一方向の回動が規制されるため、第２の腕部が切り欠き部と遊嵌している状態において、切り欠き部以外の部分で第２の腕部の一方向の回動を規制することができるため、ねじりばねの姿勢が安定する。なお、この第３の規制面は、例えば切り欠き部の輪郭をなす壁面に連続して形成するようにしてもよい。 In the above configuration, the third restriction surface restricts the rotation of the second arm part in one direction, so that the notch part is loosely fitted with the notch part. Since the rotation of the second arm portion in one direction can be restricted by a portion other than the portion, the posture of the torsion spring is stabilized. In addition, you may make it form this 3rd control surface continuously on the wall surface which makes the outline of a notch part, for example.

請求項３に記載の発明は、請求項１又は２に記載の発明において、前記第２の規制面には、前記第１の規制面寄りの部位に前記切り欠き部の入口に近づくにつれて***する傾斜面が形成されている要旨とする。 According to a third aspect of the present invention, in the first or second aspect of the present invention, the second restricting surface rises as it approaches the entrance of the notch at a portion near the first restricting surface. The gist is that the inclined surface is formed.

上記の構成では、第２の腕部を第２の規制面に当接させてスライドさせる際に、第２の腕部の端部と第２の規制面との間で発生する摩擦力と、この第２の腕部をスライドさせる力とがねじりばねに作用するため、このねじりばね全体が傾くことがある。この点、上記の構成によれば、切り欠き部の入口に近くでは、第２の腕部の端部の第１の規制面寄りの部位が、この傾斜面によって第２の規制面よりも相対的に持ち上げられるために、このような傾きの発生が抑制される。また、このような***する傾斜面を備えていることから、第２の腕部の端部が切り欠き部と遊嵌した状態で、第２の腕部が切り欠き部から外れにくくなるといった付随的な効果をも奏することができる。 In the above configuration, when the second arm portion is brought into contact with the second restriction surface and slid, the frictional force generated between the end portion of the second arm portion and the second restriction surface; Since the force for sliding the second arm portion acts on the torsion spring, the entire torsion spring may be inclined. In this regard, according to the above configuration, near the entrance of the notch, the portion of the end of the second arm portion near the first restriction surface is more relative to the second restriction surface than the second restriction surface. Therefore, the occurrence of such inclination is suppressed. In addition, since such an inclined surface is provided, the second arm portion is unlikely to be detached from the notch in a state where the end of the second arm is loosely fitted with the notch. Effects can also be achieved.

請求項４に記載の発明は、請求項１〜３の何れかに記載の発明において、前記ガイド部と前記第２の部材とは一体成形されていることを要旨とする。
このように、第２の部材とガイド部とを一体成形すれば、部品点数の削減できるとともに、第２の部材へガイド部に固定する工程を省略することができる。 The gist of the invention according to claim 4 is that, in the invention according to any one of claims 1 to 3, the guide portion and the second member are integrally formed.
As described above, if the second member and the guide portion are integrally formed, the number of parts can be reduced, and the step of fixing the guide member to the second member can be omitted.

請求項５に記載の発明は、請求項１〜４の何れかに記載の発明において、前記第２の部材は、開口を備える筐体で構成され、前記第１の部材は、前記筐体に対して回動軸を介して回動自在に支持されて前記開口を開閉する蓋で構成されることを要旨とする。 The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the second member is configured by a housing having an opening, and the first member is mounted on the housing. On the other hand, the gist of the invention is that the cover is configured to be pivotably supported via a pivot shaft and to open and close the opening.

上記の構成では、筐体を有する第２の部材と蓋との間にねじりばねを取り付けることにより、この蓋の開閉をねじりばねによって付勢する。
請求項６に記載の発明は、請求項１〜４の何れかに記載の発明において、前記第２の部材は、開口を有する筐体を備え、前記第１の部材は、前記筐体に対して回動軸を介して互いに反対方向に回動することにより前記開口を開閉する２つの蓋で構成され、前記筐体と前記各蓋との間には、前記各ねじりばねが略同一の方向で架設されることを要旨とする。 In the above configuration, the torsion spring is attached between the second member having the housing and the lid, and the opening and closing of the lid is urged by the torsion spring.
The invention according to claim 6 is the invention according to any one of claims 1 to 4, wherein the second member includes a housing having an opening, and the first member is And two lids that open and close the opening by pivoting in opposite directions via a pivot shaft, and the torsion springs are substantially in the same direction between the housing and the lids. The main point is that

上記の構成では、各蓋体に対してねじりばねを略同一の方向で架設しているため、同一のねじりばねを用いることができる。 In said structure, since the torsion spring is constructed in the substantially the same direction with respect to each cover body, the same torsion spring can be used.

本発明のねじりばねの取り付け構造によれば、ねじりばねを第１の部材の係止部に係止させた状態で、ガイド部の各規制面により第２の腕部の端部の２方向の位置規制を容易に行うことができるため、第２の腕部の端部を切り欠き部と容易に遊嵌させることができる。 According to the torsion spring mounting structure of the present invention, in the state where the torsion spring is locked to the locking portion of the first member, the two arm portions of the end portion of the second arm portion are moved by the respective restricting surfaces of the guide portion. Since the position can be easily regulated, the end portion of the second arm portion can be easily loosely fitted to the notch portion.

次に、このカップホルダ２０における各蓋４１，４２の開閉動作について説明する。図２に示すようにこのカップホルダ２０の蓋４１，４２が閉じられた状態で、乗員がこのカップホルダ２０を利用する際には、まず、乗員の操作によって例えば前側蓋４１に図２の矢印Ａの方向に向って回動する力が加えられ、この前側蓋４１が回動軸３７ａ，３７ｃを介して筐体２１に対して回動する。この際、側板４３ａの貫通孔４８も、回動軸３７ａを回動中心として図の矢印ａに示すように後方に向って回動し、これに伴ってねじりばね８０の第１の腕部８２もこの貫通孔４８とともに移動する。このような乗員の操作によって、ねじりばね８０は第１の腕部８２と第２の腕部８３とがなす「Ｖ」字が閉じられるように第１の腕部８２及び第２の腕部８３がコイル部８１を中心に回動する。そして、乗員がこの前側蓋４１をある程度の状態まで開くと、その後は乗員によって蓋４１を開く力が加えられなくても、ねじりばね８０の「Ｖ」字を開いて通常の状態に戻ろうとする復元力によって前側蓋４１が開く方向に付勢される。同様に、乗員の操作によって後側蓋４２が図２の矢印Ｂの方向に向って回動する力が加えられると、この後側蓋４２が回動軸３７ｂ，３７ｄを回動中心として回動するとともに、側板４４ａの貫通孔４９は、回動軸３７ｂを回動中心として図の矢印ｂに示すように回動して前方へ移動し、図３に示す状態となる。そして、この際にも、乗員がこの後側蓋４２をある程度の状態まで開くと、その後は乗員による蓋４２を開く力が加えられなくても、ねじりばね９０の復元力によって後側蓋４２が開く方向に付勢される。また、カップホルダ２０の蓋４１，４２が図３に示すように開いた状態で乗員がこのカップホルダ２０を利用しなくなった場合にも、同様の原理によって、乗員が蓋４１，４２をある程度の状態まで閉じると、その後は、ねじりばね８０，９０の復元力によって蓋４１，４２は閉じる方向へと付勢される。 Next, the opening / closing operation | movement of each lid | cover 41 and 42 in this cup holder 20 is demonstrated. When the occupant uses the cup holder 20 with the lids 41 and 42 of the cup holder 20 closed as shown in FIG. 2, first, for example, the arrow on the front lid 41 is applied to the front lid 41 by the operation of the occupant. A force rotating in the direction of A is applied, and the front lid 41 rotates with respect to the casing 21 via the rotation shafts 37a and 37c. At this time, the through hole 48 of the side plate 43a is also rotated backward as indicated by an arrow a in the drawing with the rotation shaft 37a as the rotation center, and accordingly, the first arm portion 82 of the torsion spring 80 is rotated. Also moves with the through hole 48. By such an occupant's operation, the torsion spring 80 has the first arm portion 82 and the second arm portion 83 so that the “V” shape formed by the first arm portion 82 and the second arm portion 83 is closed. Rotates around the coil portion 81. When the occupant opens the front lid 41 to a certain state, the "V" shape of the torsion spring 80 is opened to return to the normal state even if the occupant does not apply a force to open the lid 41 thereafter. The restoring force urges the front lid 41 in the opening direction. Similarly, when a force is applied to rotate the rear lid 42 in the direction of arrow B in FIG. 2 by the operation of the occupant, the rear lid 42 rotates about the rotation shafts 37b and 37d. At the same time, the through hole 49 of the side plate 44a rotates about the rotation shaft 37b as the center of rotation as indicated by the arrow b in the figure, and moves forward, resulting in the state shown in FIG. Also in this case, when the occupant opens the rear lid 42 to a certain state, the rear lid 42 is moved by the restoring force of the torsion spring 90 even if no force is applied to open the lid 42 by the occupant thereafter. It is biased in the opening direction. Further, even when the occupant stops using the cup holder 20 with the lids 41 and 42 of the cup holder 20 opened as shown in FIG. 3, the occupant opens the lids 41 and 42 to a certain extent according to the same principle. Once closed, the lids 41 and 42 are urged in the closing direction by the restoring force of the torsion springs 80 and 90.

上記各ねじりばね８０，９０を、各蓋４１，４２の貫通孔４８，４９と各リテーナの切り欠き部６０，６１との間で架設する際には、まず、第１の腕部８２，９２の端部を各蓋４１，４２の貫通孔４８，４９に挿入することによってこの第１の腕部８２，９２の端部が貫通孔４８，４９により係止される。そして、この状態で、ねじりばね８０，９０の第２の腕部８３，９３は、その第１の屈曲部８４，９４が第２の規制面７３，７７の上に載置されるとともに、腕本体部８７，９７が、第１の規制面７２，７６に当接させられる。つまり、この状態では、ねじりばね８０，９０の第２の腕部８３，９３の腕本体部８７，９７と第１の屈曲部８４，９４との境の角部が、第１の規制面７２，７６と第２の規制面７３，７７とがなす角部に嵌る状態となる。このようにして、第２の腕部８３，９３が、コイル部８１，９１の軸線方向においてこの第１の規制面７２，７６よりもカップホルダ２０の左右方向の左側に移動することが規制されるため、第２の腕部８３，９３の端部が、切り欠き部６０，６１に対応した位置に配置される。さらに、第２の腕部８３、９３の第１の屈曲部８４，９４がこの第２の規制面７３，７７よりも下方に移動することが規制されるために、第２の腕部８３，９３がコイル部８１，９１を中心としてねじりばね８０，９０の「Ｖ」字が開くように回動することが規制される。 When constructing the torsion springs 80 and 90 between the through holes 48 and 49 of the lids 41 and 42 and the notches 60 and 61 of the retainers, first, the first arm portions 82 and 92 are provided. Are inserted into the through holes 48 and 49 of the lids 41 and 42, so that the ends of the first arm portions 82 and 92 are locked by the through holes 48 and 49. In this state, the second arm portions 83 and 93 of the torsion springs 80 and 90 have the first bent portions 84 and 94 placed on the second restriction surfaces 73 and 77 and the arms. The main body portions 87 and 97 are brought into contact with the first restriction surfaces 72 and 76. That is, in this state, the corner portion between the arm main body portions 87 and 97 of the second arm portions 83 and 93 of the torsion springs 80 and 90 and the first bent portions 84 and 94 is the first regulating surface 72. , 76 and the second restricting surfaces 73, 77 are fitted into corners. In this way, the second arm portions 83 and 93 are restricted from moving to the left in the left-right direction of the cup holder 20 from the first restriction surfaces 72 and 76 in the axial direction of the coil portions 81 and 91. Therefore, the end portions of the second arm portions 83 and 93 are disposed at positions corresponding to the cutout portions 60 and 61. Further, since the first bent portions 84 and 94 of the second arm portions 83 and 93 are restricted from moving below the second restricting surfaces 73 and 77, the second arm portions 83 and It is restricted that 93 rotates about the coil parts 81 and 91 so that the "V" character of the torsion springs 80 and 90 may open.

そして、ねじりばね８０，９０は、このように第２の腕部８３，９３を第１の規制面７２，７６及び第２の規制面７３，７７に当接させた状態で、第２の腕部８３，９３の腕本体部８７，９７が切り欠き部６０，６１側に向って押圧されることにより、図４及び図５の矢印の方向に沿ってスライドする。ここで、本実施形態では、第２の規制面７３，７７に上記傾斜面７５，７９が形成されているために、このねじりばね８０，９０は傾くことなく安定的な姿勢を維持して、切り欠き部６０，６１に近づく。つまり、第２の腕部８３，９３の腕本体部８７，９７を切り欠き部６０，６１側に向って押圧すると、この押圧力、及び第２の腕部８３，９３と第２の規制面との間で発生する摩擦力により、腕本体部８７，９７の第１の屈曲部８４，９４側の端部がカップホルダ２０の内側（右側）に入り込むようにねじりばね８０，９０が傾くおそれがある。そこで、本実施形態では、このような傾斜面７５，７９が設けることで、第１の屈曲部８４，９４における腕本体部８７，９７側を切り欠き部６０，６１に近づくにつれて徐々に上方に持ち上げるようにして、このような傾きの発生を抑制するようにしている。 Then, the torsion springs 80 and 90 are configured so that the second arm portions 83 and 93 are in contact with the first restriction surfaces 72 and 76 and the second restriction surfaces 73 and 77 in this manner. When the arm main body portions 87 and 97 of the portions 83 and 93 are pressed toward the cutout portions 60 and 61, the arm body portions 87 and 97 slide along the directions of the arrows in FIGS. 4 and 5. Here, in this embodiment, since the inclined surfaces 75 and 79 are formed on the second restricting surfaces 73 and 77, the torsion springs 80 and 90 maintain a stable posture without being inclined, It approaches the notches 60 and 61. That is, when the arm main body portions 87 and 97 of the second arm portions 83 and 93 are pressed toward the cutout portions 60 and 61, the pressing force and the second arm portions 83 and 93 and the second restriction surface are pressed. May cause the torsion springs 80 and 90 to tilt so that the end portions of the arm main body portions 87 and 97 on the first bent portions 84 and 94 side enter the inside (right side) of the cup holder 20. There is. Therefore, in the present embodiment, by providing such inclined surfaces 75 and 79, the arm main body portions 87 and 97 side of the first bent portions 84 and 94 are gradually raised upward as they approach the notches 60 and 61. Such an inclination is suppressed by lifting.

そして、ねじりばね８０，９０は、第２の腕部８３，９３の端部が切り欠き部６０，６１に近づくにつれて、コイル部８１，９１を中心とした第２の腕部８３，９３の一方向の回動が第２の規制面７３，７７によって規制された状態で、コイル部８１，９１と第２の腕部８３，９３とがねじりばね８０，９０の「Ｖ」字が閉じる方向に相対回動する。これにより、ねじりばね８０，９０には、この「Ｖ」字を開いて通常状態に戻ろうとする復元力が作用する。そして、切り欠き部６０，６１の入口６０ａ，６１ａから延設された第２の規制面７３，７７によってねじりばね８０，９０の第２の腕部８３，９３端部が切り欠き部６０，６１の入口６０ａ，６１ａに導かれた後、ねじりばね８０，９０の復元力により第２の腕部８３，９３の端部が下方に付勢される。これにより、ねじりばね８０，９０の第２の腕部８３，９３の端部と切り欠き部６０，６１とが遊嵌する。なお、この遊嵌状態では、この第１の屈曲部８４，９４が切り欠き部６０，６１の「Ｕ」字を形成する前後の側面に挟まれるとともに、リテーナ５１，５２の側面パネル５１ａ，５２ａが第２の腕部８３，９３の腕本体部８７，９７と第２の屈曲部８５，９５とに挟まれた状態となる。 The torsion springs 80, 90 are provided as one of the second arm portions 83, 93 centered on the coil portions 81, 91 as the end portions of the second arm portions 83, 93 approach the notches 60, 61. In a state where the rotation of the direction is regulated by the second regulating surfaces 73 and 77, the coil parts 81 and 91 and the second arm parts 83 and 93 are in a direction in which the “V” shape of the torsion springs 80 and 90 is closed Relative rotation. As a result, a restoring force is applied to the torsion springs 80 and 90 to open the “V” shape and return to the normal state. Then, the second arm surfaces 83 and 93 of the torsion springs 80 and 90 are notched at the notches 60 and 61 by the second restricting surfaces 73 and 77 extending from the inlets 60a and 61a of the notches 60 and 61. Then, the ends of the second arm portions 83 and 93 are urged downward by the restoring force of the torsion springs 80 and 90. Thereby, the edge part of the 2nd arm parts 83 and 93 of the torsion springs 80 and 90 and the notch parts 60 and 61 are loosely fitted. In this loosely fitted state, the first bent portions 84 and 94 are sandwiched between the front and rear side surfaces of the cutout portions 60 and 61 forming the “U” shape, and the side panels 51 a and 52 a of the retainers 51 and 52. Is sandwiched between the arm main body portions 87 and 97 of the second arm portions 83 and 93 and the second bent portions 85 and 95.

また、この状態では、切り欠き部６０，６１の側面に連続した第３の規制面７４，７８により、第２の腕部８３，９３の第１の屈曲部８４，９４の外側（左側）がねじりばね８０，９０の「Ｖ」字が閉じる方向に回動することが規制され、第２の腕部が切り欠き部と遊嵌している状態においてねじりばね８０，９０が回動することが抑制される。さらに、第２の規制面７３，７７に上記傾斜面７５，７９を形成したことから、第３の規制面７４，７８の高さも、この第２の規制面７３，７７に対応した部位が高くなり、第２の腕部８３，９３の端部が切り欠き部６０，６１から外れにくくなる。 Further, in this state, the outer side (left side) of the first bent portions 84 and 94 of the second arm portions 83 and 93 is formed by the third restriction surfaces 74 and 78 that are continuous with the side surfaces of the cutout portions 60 and 61. The torsion springs 80 and 90 are restricted from rotating in the closing direction, and the torsion springs 80 and 90 are allowed to rotate in a state where the second arm part is loosely fitted with the notch. It is suppressed. Furthermore, since the inclined surfaces 75 and 79 are formed on the second restricting surfaces 73 and 77, the height of the third restricting surfaces 74 and 78 is also high in the portion corresponding to the second restricting surfaces 73 and 77. Thus, the end portions of the second arm portions 83 and 93 are difficult to be detached from the cutout portions 60 and 61.

以上詳述したように本実施形態によれば、以下の効果を奏することができる。
（１）本実施形態のカップホルダ２０では、ねじりばね８０，９０の第１の腕部８２，９２が蓋４１，４２の貫通孔４８，４９に係止された状態で、第２の腕部８３，９３の端部をリテーナ５１，５２の切り欠き部６０，６１に遊嵌させる際に、このねじりばねの位置を規制するガイド部７０，７１を設けるようにした。そして、このガイド部７０，７１は、第２の腕部８３，９３の端部がコイル部８１，９１の軸線方向の一方に変位することを規制する第１の規制面７２，７６と、切り欠き部６０，６１の入口６０ａ，６１ａから延設されてコイル部８１，９１を中心とした第２の腕部８３，９３の一方向の回動を規制する第２の規制面７３，７７とを有している。そのため、第２の腕部８３，９３の端部を第１の規制面７２，７６及び第２の規制面７３，７７に当接させると、第２の腕部８３，９３の端部をコイル部８１，９１の軸線方向において切り欠き部６０，６１に対応した位置に維持することができる。そして、この状態で、第２の腕部８３，９３を切り欠き部６０，６１に向ってスライドさせると、コイル部８１，９１を中心とした第２の腕部８３，９３の一方向の回動が第２の規制面７３，７７によって規制された状態で、コイル部８１，９１と第２の腕部８３，９３とがねじりばね８０，９０の「Ｖ」字が閉じる方向に相対回動する。これにより、第２の腕部８３，９３の端部が切り欠き部６０，６１の入口６０ａ，６１ａに達したときには、ねじりばね８０，９０の復元力により第２の腕部８３，９３の端部が下方に付勢されて切り欠き部６０，６１と遊嵌する。 As described above in detail, according to this embodiment, the following effects can be obtained.
(1) In the cup holder 20 of the present embodiment, the second arm portion in a state where the first arm portions 82 and 92 of the torsion springs 80 and 90 are engaged with the through holes 48 and 49 of the lids 41 and 42. When the end portions of 83 and 93 are loosely fitted into the cutout portions 60 and 61 of the retainers 51 and 52, guide portions 70 and 71 for regulating the position of the torsion spring are provided. The guide portions 70 and 71 are separated from the first restricting surfaces 72 and 76 that restrict the end portions of the second arm portions 83 and 93 from being displaced in one of the coil portions 81 and 91 in the axial direction. Second restricting surfaces 73 and 77 extending from the inlets 60a and 61a of the notches 60 and 61 and restricting the rotation of the second arm portions 83 and 93 around the coil portions 81 and 91 in one direction; have. Therefore, when the end portions of the second arm portions 83 and 93 are brought into contact with the first restricting surfaces 72 and 76 and the second restricting surfaces 73 and 77, the end portions of the second arm portions 83 and 93 are coiled. It can be maintained at a position corresponding to the cutout portions 60 and 61 in the axial direction of the portions 81 and 91. In this state, when the second arm portions 83 and 93 are slid toward the cutout portions 60 and 61, the rotation of the second arm portions 83 and 93 around the coil portions 81 and 91 in one direction is performed. In a state where the movement is regulated by the second regulating surfaces 73 and 77, the coil portions 81 and 91 and the second arm portions 83 and 93 are relatively rotated in the direction in which the “V” shape of the torsion springs 80 and 90 is closed. To do. Thus, when the end portions of the second arm portions 83 and 93 reach the inlets 60a and 61a of the cutout portions 60 and 61, the ends of the second arm portions 83 and 93 are restored by the restoring force of the torsion springs 80 and 90. The portion is urged downward and loosely fits with the notches 60 and 61.

このようにして、ねじりばね８０，９０の第１の腕部８２，９２が係止された状態で、第２の腕部８３，９３の端部の２方向についての位置規制をガイド部７０，７１によって容易に行うことができる。したがって、このねじりばね８０，９０を取り付ける際に、第２の腕部８３，９３をガイド部７０，７１に当接させれば、第２の腕部８３，９３を切り欠き部６０，６１に向ってスライドさせるための力を作用させるだけで、第２の腕部８３，９３の端部と切り欠き部６０，６１とを遊嵌させることができる。 Thus, in the state where the first arm portions 82 and 92 of the torsion springs 80 and 90 are locked, the position restriction in the two directions of the end portions of the second arm portions 83 and 93 is restricted. 71 can be easily performed. Therefore, when the torsion springs 80 and 90 are attached, if the second arm portions 83 and 93 are brought into contact with the guide portions 70 and 71, the second arm portions 83 and 93 are formed in the cutout portions 60 and 61. The end portions of the second arm portions 83 and 93 and the cutout portions 60 and 61 can be loosely fitted only by applying a force for sliding in the direction.

（２）本実施形態のカップホルダ２０では、ガイド部７０，７１が第２の腕部８３，９３の端部と切り欠き部６０，６１とが遊嵌する状態において、コイル部８１，９１を中心とした第２の腕部８３，９３の「Ｖ」字が閉じる方向で回動することを規制する第３の規制面７４，７８を備えるようにしている。これにより、第２の腕部８３，９３が切り欠き部６０，６１と遊嵌している状態においてねじりばね８０，９０がねじれることを抑制することができ、その姿勢を安定させることができる。 (2) In the cup holder 20 of the present embodiment, in the state where the guide portions 70 and 71 are loosely fitted between the end portions of the second arm portions 83 and 93 and the notches 60 and 61, the coil portions 81 and 91 are Third restriction surfaces 74 and 78 are provided for restricting the “V” shape of the second arm portions 83 and 93 at the center from rotating in the closing direction. Thereby, it is possible to prevent the torsion springs 80 and 90 from being twisted in a state where the second arm portions 83 and 93 are loosely fitted to the notches 60 and 61, and the posture can be stabilized.

（３）本実施形態のカップホルダ２０では、ガイド部７０，７１の第２の規制面７３，７７の第１の規制面７２，７６寄りの部位に切り欠き部６０，６１の入口に近づくにつれて***する傾斜面７５，７９が形成されている。これにより、ねじりばね８０，９０の第２の腕部８３，９３の端部をガイド部７０，７１の第１の規制面７２，７６と第２の規制面７３，７７とに当接させてスライドさせる際にねじりばね８０，９０の傾きが発生することを抑制することができる。 (3) In the cup holder 20 of the present embodiment, as the second restriction surfaces 73 and 77 of the guide portions 70 and 71 approach the first restriction surfaces 72 and 76 and approach the entrances of the cutout portions 60 and 61. Raised inclined surfaces 75 and 79 are formed. Accordingly, the end portions of the second arm portions 83 and 93 of the torsion springs 80 and 90 are brought into contact with the first restriction surfaces 72 and 76 and the second restriction surfaces 73 and 77 of the guide portions 70 and 71. It is possible to prevent the torsion springs 80 and 90 from tilting when sliding.

（４）本実施形態のカップホルダ２０では、前側蓋４１と後側蓋４２とが筐体２１に対して反対方向に回動するものの、各ねじりばね８０，９０はともに「Ｖ」字が後方に向って開口するといった態様で略同一の方向に取り付けられる。したがって、同一のねじりばねを用いることができ、このカップホルダ２０の部品として、互いに反対向きにコイル部の螺旋がまかれた２種類のばねを準備する必要がない。 (4) In the cup holder 20 of the present embodiment, the front lid 41 and the rear lid 42 rotate in opposite directions with respect to the casing 21, but the torsion springs 80 and 90 both have a “V” shape in the rear. They are attached in substantially the same direction in such a manner that they open toward. Therefore, the same torsion spring can be used, and it is not necessary to prepare two types of springs in which the spirals of the coil portions are wound in opposite directions as parts of the cup holder 20.

なお、本発明は次に示す別の実施形態に具体化することができる。
・上記実施形態では、ガイド部７０，７１の第２の規制面７３，７７は、第２の腕部８３、９３の一方向の回動を規制するにあたり、第２の腕部８３、９３がねじりばねの「Ｖ」字が開く方向に回動することを規制していたが、規制される一方向はこれとは反対の方向でもよい。すなわち、第２の腕部がねじりばねの「Ｖ」字が閉じる方向に回動することを規制してもよい。また、上記実施形態では、第１の規制面７２，７６により第２の腕部８３，９３の端部が、コイル部８１，９１の軸線方向において、カップホルダ２０よりも外側（左側）に移動することを規制していたが、カップホルダ２０よりも内側（右側）に移動することを規制するようにしてもよい。 Note that the present invention can be embodied in another embodiment described below.
In the above embodiment, the second restricting surfaces 73 and 77 of the guide portions 70 and 71 restrict the rotation of the second arm portions 83 and 93 in one direction. Although the rotation of the “V” of the torsion spring is restricted in the opening direction, the restricted one direction may be the opposite direction. That is, the second arm portion may be restricted from rotating in the direction in which the “V” shape of the torsion spring is closed. Moreover, in the said embodiment, the edge part of the 2nd arm parts 83 and 93 moves to the outer side (left side) rather than the cup holder 20 in the axial direction of the coil parts 81 and 91 by the 1st control surfaces 72 and 76. However, the movement to the inside (right side) of the cup holder 20 may be restricted.

ガイド部の第１の規制面及び第２の規制面が第２の腕部を上記実施形態とは反対の方向の移動することを規制した例を図６に示す。この図６に示すように、後側リテーナ６２の中間部6４には、側面パネル６４ａの後端部に下方に開口する略「Ｕ」字型の切り欠き部６５が形成される。そして、このリテーナ６２には、切り欠き部６５が形成される部位から車両の後方に向って延びるガイド部６６が固定されている。このガイド部６６は、切り欠き部６５の入口６５ａから後方且つ上方に向って延設される第２の規制面６８と、この第２の規制面６８における右側寄りの部位から鉛直下方に延びる第１の規制面６７とを備えている。この第２の規制面６８は、ねじりばね９０の第１の腕部９２の端部が貫通孔４９に貫通し且つねじりばね９０に「Ｖ」字を開閉させる力が作用しない状態で第２の腕部９３の端部が描く円弧の軌跡よりも、切り欠き部６５側に向って下方に急激に傾斜している。そして、第１及び第２の各規制面６７，６８に、ねじりばね９０の第２の腕部９３の第２の屈曲部９５及び第１の屈曲部９４をそれぞれ当接させると、コイル部９１の軸線方向において第２の腕部９３の端部と切り欠き部６５との位置が略一致する。この状態において、ねじりばね９０を図６の矢印の方向にスライドさせると、第２の腕部９３の端部が切り欠き部６５の入口６５ａに近づくにつれて、第２の腕部９３がコイル部９１を中心としてこのねじりばね９０の「Ｖ」字が開く方向に回動する。そして、第２の腕部９３の端部が切り欠き部６５に達したときには、このねじりばね９０の「Ｖ」字を閉じようとする復元力により、第２の腕部の端部が上方に付勢され切り欠き部６５とが遊嵌する。このような構成によっても、ねじりばね９０の第２の腕部９３の端部の２方向における位置を規制することができるため、ねじりばね９０を切り欠き部６５に容易に取り付けることができる。 FIG. 6 shows an example in which the first restriction surface and the second restriction surface of the guide portion restrict the movement of the second arm portion in the direction opposite to that of the above embodiment. As shown in FIG. 6, a substantially “U” -shaped notch 65 that opens downward is formed at the rear end of the side panel 64a in the intermediate portion 64 of the rear retainer 62. The retainer 62 is fixed with a guide portion 66 extending from the portion where the notch portion 65 is formed toward the rear of the vehicle. The guide portion 66 has a second restriction surface 68 extending rearward and upward from the inlet 65a of the cutout portion 65, and a second restriction surface 68 extending vertically downward from a portion on the right side of the second restriction surface 68. 1 restriction surface 67. The second restricting surface 68 is in a state where the end of the first arm portion 92 of the torsion spring 90 penetrates the through hole 49 and a force for opening and closing the “V” shape does not act on the torsion spring 90. It inclines sharply downwardly toward the notch 65 side from the locus of the circular arc drawn by the end of the arm portion 93. When the second bent portion 95 and the first bent portion 94 of the second arm portion 93 of the torsion spring 90 are brought into contact with the first and second restricting surfaces 67 and 68, respectively, the coil portion 91 is obtained. The positions of the end portion of the second arm portion 93 and the notch portion 65 substantially coincide with each other in the axial direction. In this state, when the torsion spring 90 is slid in the direction of the arrow in FIG. 6, the second arm portion 93 is moved to the coil portion 91 as the end portion of the second arm portion 93 approaches the inlet 65a of the notch portion 65. The “V” shape of the torsion spring 90 is rotated in the opening direction. When the end portion of the second arm portion 93 reaches the notch portion 65, the end portion of the second arm portion is moved upward by a restoring force for closing the “V” shape of the torsion spring 90. It is urged and the notch 65 is loosely fitted. Even with such a configuration, the position of the end portion of the second arm portion 93 of the torsion spring 90 in two directions can be restricted, so that the torsion spring 90 can be easily attached to the notch portion 65.

・上記各第１の規制面が第２の規制面から鉛直方向に延びるように形成されて第１の規制面と第２の規制面とが接続されていたが、第１の規制面と第２の規制面とは単に第２の腕部８３，９３の２方向の移動を規制することができればよく、第１の規制面と第２の規制面とは接点がなくてもよい。つまり、上記各実施形態では、ねじりばね８０，９０の第２の腕部８３，９３の腕本体部８７，９７と第１の屈曲部８４，９４との境の角部が、第１の規制面と第２の規制面とがなす角部に嵌るようにして、第２の腕部の移動を規制するようにしている。しかしながら、ガイド部は、例えば、腕本体部８７，９７の中間部のみを当接させてその移動を規制する第１の規制面と、第１の屈曲部８４，９４の中間部のみを当接させてその移動を規制する第２の規制面とを有する構成であってもよい。 The first restriction surface is formed so as to extend in the vertical direction from the second restriction surface, and the first restriction surface and the second restriction surface are connected. The second restricting surface only needs to be able to restrict the movement of the second arm portions 83 and 93 in two directions, and the first restricting surface and the second restricting surface may have no contact. That is, in each of the above embodiments, the corner portion between the arm main body portions 87 and 97 of the second arm portions 83 and 93 of the torsion springs 80 and 90 and the first bent portions 84 and 94 is the first restriction. The movement of the second arm portion is restricted by fitting in a corner formed by the surface and the second restriction surface. However, the guide part, for example, abuts only the intermediate part of the first bent parts 84 and 94 and the first restricting surface that restricts the movement by abutting only the intermediate part of the arm main body parts 87 and 97. It may be configured to have a second restriction surface that restricts the movement.

・上記各実施形態において、蓋に設けられる係止部を貫通孔で構成していたが、貫通孔ではなく第１の腕部を回動可能に軸支することができる形状であればその他の形状のものであってもよい。また、リテーナに設けられる切り欠き部の形状も上記各実施形態の形状に限定されず、例えば「Ｖ」字状であってもよいし、リテーナの側面パネルが「Ｕ」字状の切り欠き部の周囲においてこの切り欠き部よりも一回り大きい「Ｕ」字状形成して、フックのような形状に形成されていてもよい。 In each of the above embodiments, the locking portion provided on the lid is configured with a through hole, but other shapes may be used as long as the first arm portion can be pivotally supported instead of the through hole. It may be of a shape. Further, the shape of the cutout portion provided in the retainer is not limited to the shape of each of the above embodiments, and may be, for example, a “V” shape, or the side panel of the retainer has a “U” shape cutout portion. A "U" shape that is slightly larger than the notch may be formed around the periphery of the notch and may be formed in a hook-like shape.

・上記各実施形態では、筐体に対して前側及び後側の各蓋は、互いに反対方向に回動しているものの、前側及び後側の各ねじりばねは略同じ方向に取り付けるようにした。しかしながら、後側のねじりばねは、図３〜図７に示した態様で、後方に向って「Ｖ」字が開口するように取り付け、前側のねじりばねは、図３〜図７に示した態様とは異なる態様で、前方に向って「Ｖ」字が開口するように取り付けてもよい。そして、この場合は、前方及び後方のねじりばねは、互いに対称の形状のものを用いる。なお、その場合、前側リテーナの側面パネルには、前寄りの部分に切り欠き部を形成するとともに、ガイド部は、リテーナにおいて切り欠き部に対応した部位から前方に向って延設する。 In the above embodiments, the front and rear lids are rotated in opposite directions with respect to the housing, but the front and rear torsion springs are attached in substantially the same direction. However, the rear side torsion spring is mounted in such a manner as shown in FIGS. 3 to 7 so that the “V” shape is opened rearward, and the front side torsion spring is the embodiment shown in FIGS. 3 to 7. You may attach so that a "V" character may open toward the front in a different aspect. In this case, the front and rear torsion springs have symmetrical shapes. In this case, the side panel of the front retainer is formed with a notch in the front portion, and the guide portion extends forward from a portion corresponding to the notch in the retainer.

また、上記各実施形態では、２つのねじりばねを、ともにカップホルダの左側に取り付けていたが、例えば、前方のねじりばねのみをカップホルダの右側に取り付けるようにしてもよい。このような場合に、前方のねじりばねの「Ｖ」字が前方に向って開口するようにとりつければ、図３〜図７に示した後側ねじりばね９０と同じ形状のねじりばねものを用いることができる。 In the above embodiments, the two torsion springs are both attached to the left side of the cup holder. However, for example, only the front torsion spring may be attached to the right side of the cup holder. In such a case, if the “V” shape of the front torsion spring is installed so as to open toward the front, the torsion spring having the same shape as the rear side torsion spring 90 shown in FIGS. Can do.

・上記各実施形態では、カップホルダ２０が蓋４１，４２を２つ備えていたが、蓋は１つであってもよい。また、２つの蓋を備える場合であっても、これらの蓋が開閉時に同じ方向に回動するようにしてもよい。さらに、２つの蓋が互いに反対方向に回動する場合の他の例として、前側蓋がその後寄りの部位で筐体に回動自在に支持されて前方に開閉し、後側蓋がその前寄りの部位で回動自在に支持されて後方に開閉するようにしてもよい。 -In each above-mentioned embodiment, although cup holder 20 was provided with two lids 41 and 42, one lid may be sufficient. Further, even when two lids are provided, these lids may be rotated in the same direction when opened and closed. Furthermore, as another example of the case where the two lids rotate in the opposite directions, the front lid is pivotally supported by the housing at the rear portion thereof and is opened and closed forward, and the rear lid is moved forward. It is also possible to pivotally support at this part and to open and close backward.

また、上記各実施形態のカップホルダ２０において、ホルダ部３１，３２の内部の空間は、連結部３３の溝３３ａにより接続されていなくてもよい。この場合、２つの開口部３４，３５を、請求項６に記載の開口とする。 Moreover, in the cup holder 20 of each said embodiment, the space inside the holder parts 31 and 32 does not need to be connected by the groove | channel 33a of the connection part 33. FIG. In this case, the two openings 34 and 35 are the openings described in claim 6.

・上記各実施形態では、ねじりばねの取り付け構造を、車両用のカップホルダに適用したが、例えば、ダストボックス、灰皿など、第１の部材としての蓋と第２の部材としての筐体とを有するその他の物に適用してもよい。さらに、ねじりばねが取り付けられる第１の部材と第２の部材は、蓋と筐体の以外のものであってもよい。 In each of the above embodiments, the torsion spring mounting structure is applied to a vehicle cup holder.
