前記回動部材に、前記開位置から前記閉位置側への前記回動軸芯まわりの閉方向モーメントを、前記閉位置と前記開位置との間の全領域で作用させる閉方向モーメント発生機構と、
を有し、前記閉方向モーメント発生機構が、前記固定部材と前記回動部材の一方に固定して設けられるベースと、前記固定部材と前記回動部材の他方に固定して設けられる支点部材と、一端部で前記ベースに係合されるバネ部材と、長手方向一端部に前記バネ部材の他端部が係合されており長手方向中間部で前記支点部材に支持されており長手方向他端部で前記ベースに回動可能に連結されるアームと、を備えている、収容構造体装置であって、
前記ベースに、前記アームの前記ベースに対する回動範囲を規制する回動規制部が設けられている、収容構造体装置。
（２）前記回動部材は、前記回動軸部を前記固定部材の回動軸受け部に係合させ、その後に前記回動軸芯まわりに前記固定部材に対して回動させることで、前記固定部材に組付けられており、
前記アームは、前記回動部材を前記固定部材に対して前記回動軸芯まわりに回動させて前記固定部材に組付けるときに前記支点部材が接触し始める接触開始面を備えており、
前記接触開始面と、前記回動軸芯を中心とし該中心から前記支点部材が位置する位置までを半径とする円との交差角度は、前記回動部材の前記固定部材への組付け完了後に前記支点部材と接触する前記アームの面と、前記円との交差角度よりも、大とされている、（１）記載の収容構造体装置。 The present invention for achieving the above object is as follows.
(1) a fixing member having a rotating bearing portion;
A rotation shaft portion is provided, and the rotation shaft portion is rotatably supported by the rotation bearing portion so that it can be rotated around a rotation axis center between a closed position and an open position with respect to the fixed member. A rotation member in which an opening direction moment around the rotation axis from the closed position to the open position side acts in the entire region between the closed position and the open position;
A closing direction moment generating mechanism that causes the closing member to act on the rotating member in a closing direction moment around the rotation axis from the opening position to the closing position in the entire region between the closing position and the opening position; ,
The closing direction moment generating mechanism is fixed to one of the fixing member and the rotating member; and a fulcrum member fixed to the other of the fixing member and the rotating member; A spring member engaged with the base at one end, and the other end of the spring member engaged with one end in the longitudinal direction and supported by the fulcrum member at the intermediate portion in the longitudinal direction. And an arm that is pivotally connected to the base at a portion,
The accommodation structure apparatus in which the said base is provided with the rotation control part which controls the rotation range with respect to the said base of the said arm.
(2) The rotating member engages the rotating shaft portion with the rotating bearing portion of the fixed member, and then rotates the rotating member with respect to the fixed member around the rotating shaft core. It is assembled to the fixed member,
The arm includes a contact start surface on which the fulcrum member starts to contact when the rotating member is rotated around the rotation axis with respect to the fixed member and assembled to the fixed member.
The intersecting angle between the contact start surface and a circle having a radius from the center to the position where the fulcrum member is located is the center of the rotation axis after the assembly of the rotation member to the fixed member is completed. The housing structure device according to (1), wherein the housing structure device is larger than an intersection angle between the surface of the arm that contacts the fulcrum member and the circle.

上記（１）の収容構造体装置によれば、つぎの効果を得ることができる。
アームの回動範囲を規制する回動規制部が設けられているため、回動部材を固定部材に組付けるときに組付作業者がアームを手で支えなくても、回動部材を固定部材に組付けたときにアームを支点部材に対して正規の位置に（閉方向モーメント発生機構が正常に作動する位置に）組付けることができる。よって、閉方向モーメント発生機構が設けられている場合であっても、回動部材の固定部材への組付け作業の困難化を招くことを抑制できる。 According to the housing structure device of the above (1), the following effects can be obtained.
Since the rotation restricting portion for restricting the rotation range of the arm is provided, the rotation member can be fixed even if the assembly operator does not support the arm by hand when the rotation member is assembled to the fixing member. When assembled, the arm can be assembled at a normal position with respect to the fulcrum member (at a position where the closing direction moment generation mechanism operates normally). Therefore, even if the closing direction moment generation mechanism is provided, it is possible to suppress the difficulty in assembling the rotating member to the fixed member.

上記（２）の収容構造体装置によれば、つぎの効果を得ることができる。
接触開始面と、回動軸芯を中心とし該中心から支点部材が位置する位置までを半径とする円との交差角度が、回動部材の固定部材への組付け完了後に支点部材と接触するアームの面と、前記円との交差角度よりも、大とされているため、回動部材の固定部材への組付け時に接触開始面がアームを支点部材に対して正規の位置に（閉方向モーメント発生機構が正常に作動する位置に）導くガイドとして働き得る。そのため、回動部材を固定部材に組付けるときに組付作業者がアームを手で支えなくても、回動部材を固定部材に組付けたときにアームを支点部材に対して正規の位置に（閉方向モーメント発生機構が正常に作動する位置に）より確実に組付けることができる。 According to the housing structure device of the above (2), the following effects can be obtained.
The intersection angle between the contact start surface and a circle having a radius from the center to the position where the fulcrum member is located is in contact with the fulcrum member after the rotation member is assembled to the fixed member. Since the crossing angle between the arm surface and the circle is larger, the contact start surface is positioned at a normal position with respect to the fulcrum member when the rotating member is assembled to the fixed member (closed direction). It can serve as a guide to guide the moment generating mechanism to a position where it operates normally. Therefore, even when the assembling operator does not support the arm with his / her hand when assembling the rotating member to the fixed member, when the rotating member is assembled to the fixed member, the arm is brought into a normal position with respect to the fulcrum member. It can be assembled more securely (in the position where the closing moment generating mechanism operates normally).

以下に、本発明実施例の収容構造体装置を、図面を参照して、説明する。なお、図中ＦＲは車両前方を示し、ＵＰは上方を示す。
本発明実施例の収容構造体装置１０は、たとえば、図２に示すように、車両の助手席前方のインストルメントパネル部位に配置される、いわゆるビンタイプ（ボックス部自体が開閉動するタイプ）の車両用グローブボックス装置である。ただし、収容構造体装置１０は、いわゆるドアタイプ（ドアのみが開閉動するタイプ）の車両用グローブボックス装置であってもよい。また、収容構造体装置１０は、車両用グローブボックス装置に限定されるものではく、インストルメントパネルの車幅方向中央部かつ下部に配置される車両用センターロアボックス装置であってもよく、車室天井に配置される車両用小物入れ装置であってもよく、その他の装置であってもよい。
以下、本発明実施例および図示例では、収容構造体装置１０がいわゆるビンタイプの車両用グローブボックス装置である場合を例にとって説明する。 Hereinafter, a housing structure apparatus according to an embodiment of the present invention will be described with reference to the drawings. In the figure, FR indicates the front of the vehicle, and UP indicates the upper side.
The housing structure device 10 according to the embodiment of the present invention is, for example, as shown in FIG. It is a glove box device for vehicles. However, the housing structure device 10 may be a so-called door type (a type in which only a door is opened and closed) for a vehicle glove box device. In addition, the housing structure device 10 is not limited to the vehicle glove box device, but may be a vehicle center lower box device disposed at the center and the lower portion of the instrument panel in the vehicle width direction. It may be a vehicle accessory device arranged on the ceiling of the room, or may be another device.
Hereinafter, in the embodiment of the present invention and the illustrated example, the case where the housing structure device 10 is a so-called bin-type vehicle glove box device will be described as an example.

収容構造体装置１０は、固定部材２０と、回動部材３０と、閉方向モーメント発生機構４０と、を有する。 The housing structure device 10 includes a fixing member 20, a rotating member 30, and a closing direction moment generating mechanism 40.

固定部材２０は、車両の内装部材であるインストルメントパネルに対して固定される部材である。固定部材２０は、車室側（車両後方）に開放する凹部２１ａを備える凹部形成壁２１を備える。凹部形成壁２１は、インストルメントパネルに一体に形成されていてもよく、インストルメントパネルと別体に形成されてインストルメントパネルに固定して取付けられていてもよい。
固定部材２０は、凹部２１ａの下端部かつ車両後方側端部またはその近傍に、回動部材３０を回動可能に支持する回動軸受け部２２を備える。 The fixing member 20 is a member that is fixed to an instrument panel that is an interior member of the vehicle. The fixing member 20 includes a recess forming wall 21 including a recess 21a that opens to the passenger compartment side (rear side of the vehicle). The recess forming wall 21 may be formed integrally with the instrument panel, or may be formed separately from the instrument panel and fixedly attached to the instrument panel.
The fixing member 20 includes a rotation bearing portion 22 that rotatably supports the rotation member 30 at the lower end portion of the concave portion 21a and the vehicle rear side end portion or the vicinity thereof.

回動部材３０は、図１に示すように、上方に開放し収容物を収容可能な収容部Ｓを備える。回動部材３０は、下端部（その近傍を含む）に回動軸部３１を備える。回動部材３０は、回動軸部３１が回動軸受け部２２に回動可能に支持されることで、図２および図４に示すように、固定部材２０に対して閉位置３０ａ（図２参照）と開位置３０ｂ（図４参照）とに上下方向に回動軸芯Ｐまわりに回動可能とされている。回動軸芯Ｐは、回動部材３０の下端部（その近傍を含む）で車両左右方向に延びている。
回動部材３０は、図９に示すように、回動軸部３１を回動軸受け部２２に係合させ、その後に、図１０、図１１に示すように、回動軸芯Ｐまわりに固定部材２０に対して上方に閉位置３０ａ側に回動させることで、固定部材２０に組付けられる。 As shown in FIG. 1, the rotating member 30 includes an accommodating portion S that opens upward and can accommodate an accommodated item. The rotation member 30 includes a rotation shaft portion 31 at a lower end portion (including the vicinity thereof). As shown in FIGS. 2 and 4, the rotation member 30 is supported by the rotation shaft portion 31 so as to be rotatable on the rotation bearing portion 22, so that the rotation member 30 is in a closed position 30 a (FIG. 2). (See FIG. 4) and the open position 30b (see FIG. 4). The pivot axis P extends in the vehicle left-right direction at the lower end portion (including the vicinity thereof) of the pivot member 30.
As shown in FIG. 9, the rotating member 30 engages the rotating shaft portion 31 with the rotating bearing portion 22, and then fixed around the rotating shaft core P as shown in FIGS. 10 and 11. The fixed member 20 is assembled by rotating the member 20 upward toward the closed position 30a.

回動部材３０が閉位置３０ａにあるとき、回動部材３０には公知のロック装置によるロックがかかっており、使用者の意思に反して閉位置３０ａにある回動部材３０が固定部材２０に対して開位置３０ｂ側に移動することが規制されている。回動部材３０の閉位置３０ａから開位置３０ｂへの移動は、ロック装置がアンロックされることで可能となる。
回動部材３０の固定部材２０に対する回動速度は、図示略のダンパを設けることで、制御されていてもよい。 When the rotating member 30 is in the closed position 30a, the rotating member 30 is locked by a known locking device, and the rotating member 30 in the closed position 30a is against the fixing member 20 against the intention of the user. On the other hand, movement to the open position 30b side is restricted. The rotation member 30 can be moved from the closed position 30a to the open position 30b by unlocking the lock device.
The rotation speed of the rotation member 30 with respect to the fixing member 20 may be controlled by providing a damper (not shown).

回動部材３０は、図２に示す閉位置３０ａにあるとき、回動部材３０（回動部材３０に固定される部材を含む）の一部が固定部材２０に当接しておりそれ以上固定部材２０に対して閉側に移動することが規制されている。回動部材３０が閉位置３０ａにあるとき、回動部材３０と固定部材２０との当接打音は、固定部材２０と回動部材３０（回動部材３０に固定される部材を含む）の少なくともいずれか一方に設けられるクッションゴム５１により抑制されている。回動部材３０が閉位置３０ａにあるとき、収容部Ｓの開口は凹部２１ａ内に位置しており、使用者は収容部Ｓに収容物を出し入れできない。
回動部材３０は、図４に示す開位置３０ｂにあるとき、回動部材３０（回動部材３０に固定される部材を含む）に設けられるストッパ５２が固定部材２０の図示略のストッパ当接部に当接しておりそれ以上固定部材２０に対して開側に移動することが規制されている。回動部材３０が開位置３０ｂにあるとき、回動部材３０と固定部材２０との当接打音は、固定部材２０と回動部材３０（回動部材３０に固定される部材を含む）との少なくともいずれか一方に設けられる図示略のゴム部材により抑制されていてもよい。回動部材３０が開位置３０ｂにあるとき、収容部Ｓの開口が凹部２１ａから出て車室内に位置しており、使用者は収容部Ｓに収容物を出し入れできる。 When the rotating member 30 is in the closed position 30a shown in FIG. 2, a part of the rotating member 30 (including a member fixed to the rotating member 30) is in contact with the fixed member 20, and the fixed member is no more. The movement to the closing side with respect to 20 is restricted. When the rotating member 30 is in the closed position 30a, the contact sound between the rotating member 30 and the fixing member 20 is generated between the fixing member 20 and the rotating member 30 (including members fixed to the rotating member 30). It is suppressed by cushion rubber 51 provided on at least one of them. When the rotating member 30 is in the closed position 30 a, the opening of the storage portion S is located in the recess 21 a, and the user cannot put in and out the stored matter in the storage portion S.
When the rotating member 30 is in the open position 30b shown in FIG. 4, a stopper 52 provided on the rotating member 30 (including a member fixed to the rotating member 30) is in contact with a stopper (not shown) of the fixed member 20. It is in contact with the portion, and further movement to the open side with respect to the fixing member 20 is restricted. When the rotating member 30 is in the open position 30b, the contact sound between the rotating member 30 and the fixing member 20 is generated by the fixing member 20 and the rotating member 30 (including members fixed to the rotating member 30). It may be suppressed by an unillustrated rubber member provided on at least one of the above. When the rotating member 30 is in the open position 30b, the opening of the housing portion S is located in the vehicle interior through the recess 21a, and the user can put in and out the stored material in the housing portion S.

回動部材３０の重心Ｇは、図２に示すように、回動部材３０の回動軸芯Ｐよりも車両後方側（車室内側）にある。回動部材３０の重心Ｇには、閉位置３０ａから開位置３０ｂ側に自重がかかっている。回動部材３０の重心Ｇに閉位置３０ａから開位置３０ｂ側への自重がかかっているため、回動部材３０には、閉位置３０ａから開位置３０ｂ側への回動軸芯Ｐまわりの開方向モーメント（回転モーメント）Ｍ１が閉位置３０ａと開位置３０ｂとの間の全領域（両端含む）で作用している。
重心Ｇと回動軸芯Ｐとの車両前後方向距離Ｆ（Ｆ１，Ｆ２，Ｆ３）は、図２、図３、図４に順に示すように、回動部材３０が閉位置３０ａから開位置３０ｂ側に移動するにつれて滑らかに徐々に大きくなる。このため、回動部材３０に作用する回動軸芯Ｐまわりの開方向モーメントＭ１は、回動部材３０が閉位置３０ａから開位置３０ｂ側に移動するにつれて滑らかに徐々に大きくなる。 As shown in FIG. 2, the center of gravity G of the rotation member 30 is located on the vehicle rear side (vehicle interior side) with respect to the rotation axis P of the rotation member 30. The gravity center G of the rotating member 30 is subjected to its own weight from the closed position 30a to the open position 30b. Since the center of gravity G of the rotation member 30 is subjected to its own weight from the closed position 30a to the open position 30b, the rotation member 30 is opened around the rotation axis P from the closed position 30a to the open position 30b. A directional moment (rotational moment) M1 acts in the entire region (including both ends) between the closed position 30a and the open position 30b.
The vehicle front-rear direction distance F (F1, F2, F3) between the center of gravity G and the pivot axis P is such that the pivot member 30 is moved from the closed position 30a to the open position 30b as shown in FIGS. As it moves to the side, it gradually increases gradually. For this reason, the opening direction moment M1 around the rotation axis P acting on the rotation member 30 gradually and gradually increases as the rotation member 30 moves from the closed position 30a to the open position 30b.

閉方向モーメント発生機構４０は、図２に示すように、回動部材３０に、開位置３０ｂから閉位置側３０ａへの回動軸芯Ｐまわりの閉方向モーメント（回転モーメント）Ｍ２を、閉位置３０ａと開位置３０ｂとの間の全領域（両端含む）で作用させる機構である。
閉方向モーメント発生機構４０は、回動部材３０の車両左右方向の一側の側部に設けられている。ただし、閉方向モーメント発生機構４０は、回動部材３０の車両左右方向の両側部に対応させて一対設けられていてもよい。 As shown in FIG. 2, the closing direction moment generating mechanism 40 applies a closing direction moment (rotational moment) M2 around the rotation axis P from the open position 30b to the closed position side 30a. This is a mechanism that operates in the entire region (including both ends) between 30a and the open position 30b.
The closing direction moment generating mechanism 40 is provided on one side of the rotating member 30 in the left-right direction of the vehicle. However, a pair of closing direction moment generating mechanisms 40 may be provided corresponding to both sides of the turning member 30 in the vehicle left-right direction.

閉方向モーメント発生機構４０は、図１に示すように、固定部材２０と回動部材３０の一方に固定して設けられるベース４１と、固定部材２０と回動部材３０の他方に固定して設けられる支点部材４２と、一端部でベース４１に係合されるバネ部材４３と、長手方向一端部４４ａにバネ部材４３の他端部が係合されており長手方向中間部４４ｂで支点部材４２に支持されており長手方向他端部４４ｃでベース４１に回動可能に連結されるアーム４４と、を備える。
なお、本発明実施例および図示例では、ベース４１が回動部材３０に固定して設けられており、支点部材４２が固定部材２０に固定して設けられる場合を例にとって説明する。 As shown in FIG. 1, the closing direction moment generating mechanism 40 is provided by being fixed to one of the fixed member 20 and the rotating member 30 and fixed to the other of the fixing member 20 and the rotating member 30.

And an arm 44 that is supported and pivotally connected to the base 41 at the other longitudinal end 44c.
In the embodiment of the present invention and the illustrated example, a case where the base 41 is fixed to the rotating member 30 and the fulcrum member 42 is fixed to the fixing member 20 will be described as an example.

ベース４１は、金属製または樹脂製である。ベース４１は、回動部材３０に一体に形成されていてもよく、回動部材３０と別体に形成されて回動部材３０に図示略のビス等を用いて固定して取付けられていてもよい。
ベース４１は、ベース本体４１ａと、アーム連結部４１ｂと、バネ係合部４１ｃと、アーム差込孔４１ｄと、回動規制部４１ｆと、を備える。 The base 41 is made of metal or resin. The base 41 may be formed integrally with the rotating member 30, or may be formed separately from the rotating member 30 and fixedly attached to the rotating member 30 using screws (not shown). Good.
The base 41 includes a base main body 41a, an arm connecting portion 41b, a spring engaging portion 41c, an arm insertion hole 41d, and a rotation restricting portion 41f.

ベース本体４１ａは、略平板状である。ベース４１は、ベース本体４１ａにて回動部材３０に固定される。ベース本体４１ａに支点部材４２が干渉するおそれがある場合には、ベース本体４１ａに支点部材４２との干渉を抑制するための逃げ部４１ｅが設けられていてもよい。
アーム連結部４１ｂは、回動部材３０が閉位置３０ａにあるときにおけるベース本体４１ａの車両後方側端部（近傍を含む）に設けられる。アーム連結部４１ｂには、アーム４４が軸芯Ｐ１まわりに回動可能に連結されている。
バネ係合部４１ｃには、バネ部材４３の一端部が係合される（引っ掛けられる）。 The base body 41a has a substantially flat plate shape. The base 41 is fixed to the rotating member 30 by a base body 41a. When the fulcrum member 42 may interfere with the base main body 41a, the base main body 41a may be provided with an escape portion 41e for suppressing interference with the fulcrum member 42.
The arm connecting portion 41b is provided at the vehicle rear side end portion (including the vicinity) of the base body 41a when the rotating member 30 is in the closed position 30a. An arm 44 is connected to the arm connecting portion 41b so as to be rotatable around the axis P1.
One end of the spring member 43 is engaged (hooked) with the spring engaging portion 41c.

アーム差込孔４１ｄは、アーム４４のベース４１に対する軸芯Ｐ１の延び方向と直交する方向に延びている。アーム差込孔４１ｄには、アーム４４の長手方向一端部（車両前方側端部、近傍を含む）４４ａが差し込まれている。アーム差込孔４１ｄの幅は、図８に示すように、アーム４４の長手方向一端部４４ａの軸芯Ｐ１の延び方向における厚みより僅かに大とされている。アーム差込孔４１ｄにアーム４４が差し込まれているため、アーム４４がベース４１に対して軸芯Ｐ１の延び方向に移動すること（浮き上がること）を抑制できる。 The arm insertion hole 41d extends in a direction orthogonal to the extending direction of the shaft core P1 with respect to the base 41 of the arm 44. One end of the arm 44 in the longitudinal direction (including the vehicle front side end and the vicinity) 44a is inserted into the arm insertion hole 41d. As shown in FIG. 8, the width of the arm insertion hole 41d is slightly larger than the thickness of the longitudinal end portion 44a of the arm 44 in the extending direction of the axis P1. Since the arm 44 is inserted into the arm insertion hole 41d, the movement of the arm 44 in the extending direction of the shaft core P1 with respect to the base 41 can be suppressed.

回動規制部４１ｆは、アーム４４のベース４１に対する軸芯Ｐ１まわりの回動範囲を規制する。回動規制部４１ｆは、アーム差込孔４１ｄの延び方向の一端縁（下縁）に位置するベース４１部分からなる。回動規制部４１ｆは、閉方向モーメント発生機構４０を固定部材２０と回動部材３０に組付けた後であって回動部材３０を固定部材２０に組付ける前に、バネ部材４３による付勢力によりアーム４４がベース４１に対して所定位置よりも下方に回動することを規制する。なお、この「所定位置」とは、回動部材３０を固定部材２０に組付けるときに組付作業者がアーム４４を手で支えなくても、回動部材３０を固定部材２０に組付けたときにアーム４４を支点部材４２に対して正規の位置に（閉方向モーメント発生機構４０が正常に作動する位置に）組付けることができる位置である。 The rotation restricting portion 41 f restricts the rotation range around the axis P <b> 1 with respect to the base 41 of the arm 44. The rotation restricting portion 41f includes a base 41 portion located at one end edge (lower edge) in the extending direction of the arm insertion hole 41d. The rotation restricting portion 41 f is an urging force by the spring member 43 after the closing direction moment generating mechanism 40 is assembled to the fixing member 20 and the rotating member 30 and before the rotating member 30 is assembled to the fixing member 20. This restricts the arm 44 from rotating below the predetermined position with respect to the base 41. The “predetermined position” means that the rotating member 30 is assembled to the fixed member 20 even when the assembling operator does not support the arm 44 by hand when the rotating member 30 is assembled to the fixed member 20. In some cases, the arm 44 can be assembled to the fulcrum member 42 at a normal position (at a position where the closing moment generating mechanism 40 operates normally).

支点部材４２は、図１に示すように、たとえば、円柱ピン形状である。支点部材４２は、金属製または樹脂製である。支点部材４２は、固定部材２０からアーム４４側に突出して設けられている。支点部材４２の少なくとも突出方向先端部は、アーム４４の溝４４ｄに入り込んでおり、溝４４ｄの上面（上縁）に当接している。支点部材４２は、回動部材３０が固定部材２０に対して開閉動する際、溝４４ｄ内を溝４４ｄの上面（上縁）に摺動しながら溝４４ｄの長手方向に移動する。 As shown in FIG. 1, the fulcrum member 42 has, for example, a cylindrical pin shape. The fulcrum member 42 is made of metal or resin. The fulcrum member 42 is provided so as to protrude from the fixing member 20 to the arm 44 side. At least the distal end portion of the fulcrum member 42 enters the groove 44d of the arm 44, and is in contact with the upper surface (upper edge) of the groove 44d. The fulcrum member 42 moves in the longitudinal direction of the groove 44d while sliding in the groove 44d on the upper surface (upper edge) of the groove 44d when the rotating member 30 is opened and closed with respect to the fixed member 20.

バネ部材４３は、図２に示すように、ベース４１に対して、アーム４４にバネ力（付勢力）を付与するために設けられる。バネ部材４３は、たとえばコイルバネからなる。ただし、バネ部材４３は、アーム４４にバネ力を付与できるのであれば、コイルバネに限定されるものではなく、コンストンスプリング、トーションバネ、板バネ等であってもよい。バネ部材４３は、一端部でベース４１のバネ係合部４１ｃに係合されており（引っ掛けられており）、他端部でアーム４４の長手方向一端部（車両前方側端部、近傍を含む）４４ａに設けられるバネ係合部４４ｆに係合されており（引っ掛けられており）、アーム４４の長手方向一端部４４ａを下方に付勢している。 As shown in FIG. 2, the spring member 43 is provided to apply a spring force (biasing force) to the arm 44 with respect to the base 41. The spring member 43 is made of a coil spring, for example. However, the spring member 43 is not limited to a coil spring as long as it can apply a spring force to the arm 44, and may be a conston spring, a torsion spring, a leaf spring, or the like. The spring member 43 is engaged (hanged) at one end with the spring engaging portion 41c of the base 41, and includes one end in the longitudinal direction of the arm 44 (the vehicle front side end and the vicinity) at the other end. ) Is engaged (hanged) with a spring engaging portion 44f provided on 44a, and urges one end 44a in the longitudinal direction of the arm 44 downward.

アーム４４は、アーム４４の長手方向に延びている。回動部材３０が閉位置３０ａにあるときにおけるアーム４４の長手方向は、車両前後方向である。アーム４４は、金属製であってもよく樹脂製であってもよい。また、アーム４４は、一部品構成であってもよく、複数部品構成であってもよい。なお、本発明図示例では、アーム４４が、金属製の第１のアーム４５と、樹脂製であり第１のアーム４５に固定して取付けられる第２のアーム４６と、の２部品構成である場合を示している。 The arm 44 extends in the longitudinal direction of the arm 44. The longitudinal direction of the arm 44 when the rotating member 30 is in the closed position 30a is the vehicle front-rear direction. The arm 44 may be made of metal or resin. Further, the arm 44 may have a one-part configuration or a multi-part configuration. In the illustrated example of the present invention, the arm 44 has a two-part configuration of a first arm 45 made of metal and a second arm 46 made of resin and fixedly attached to the first arm 45. Shows the case.

アーム４４には、アーム４４の長手方向に延びており支点部材４２が摺動可能に差し込まれる溝４４ｄが設けられている。ただし、本発明実施例の変形例を示す図１３に示すように、支点部材４２がアーム４４の、アーム４４の長手方向に延びる下面（下縁）に摺動接触する場合には、溝４４ｄは設けられていなくてもよい。 The arm 44 is provided with a groove 44d that extends in the longitudinal direction of the arm 44 and into which the fulcrum member 42 is slidably inserted. However, as shown in FIG. 13 showing a modification of the embodiment of the present invention, when the fulcrum member 42 is in sliding contact with the lower surface (lower edge) of the arm 44 extending in the longitudinal direction of the arm 44, the groove 44d is It may not be provided.

アーム４４には、図１に示すように、直角または略直角に２回折れ曲ることで構成されるクランク形状部４４ｅが設けられている。クランク形状部４４ｅは、閉方向モーメント発生機構４０を固定部材２０と回動部材３０に組付けた後であって回動部材３０を固定部材２０に組付けるときに、支点部材４２がベース４１のアーム差込孔４１ｄの周縁部に当たり装置１０の組付けを阻害することを抑制するために設けられている。 As shown in FIG. 1, the arm 44 is provided with a crank-shaped portion 44 e configured by bending twice at a right angle or a substantially right angle. The crank-shaped portion 44e is configured so that the fulcrum member 42 of the base 41 is not attached to the base member 41 when the turning member 30 is attached to the fixing member 20 after the closing direction moment generating mechanism 40 is attached to the fixing member 20 and the rotating member 30. It is provided to prevent the assembly of the device 10 from being blocked by hitting the peripheral edge of the arm insertion hole 41d.

アーム４４は、図１０に示すように、回動部材３０を固定部材２０に対して回動軸芯Ｐまわりに回動させて固定部材２０に組付けるときに支点部材４２が接触し始める接触開始面４４ｇを備えている。なお、接触開始面４４ｇは、回動部材３０を固定部材２０に組付け完了後、回動部材３０の固定部材２０に対する開閉位置によらず、支点部材４２と接触しない。
図１２に示すように、接触開始面４４ｇと、回動軸芯Ｐを中心とし該中心から支点部材４２が位置する位置までを半径とする円Ｃとの交差角度（相対角度）θ１は、回動部材３０の固定部材２０への組付け完了後に支点部材４２と接触するアーム４４の面と、円Ｃとの交差角度（相対角度）θ２よりも、大とされている。 As shown in FIG. 10, the arm 44 starts to contact the fulcrum member 42 when the rotating member 30 is rotated about the rotation axis P with respect to the fixed member 20 and assembled to the fixed member 20. A surface 44g is provided. The contact start surface 44g does not contact the fulcrum member 42 regardless of the opening / closing position of the rotation member 30 with respect to the fixing member 20 after the rotation member 30 is assembled to the fixing member 20.
As shown in FIG. 12, the intersecting angle (relative angle) θ1 between the contact start surface 44g and the circle C having a radius from the center to the position where the fulcrum member 42 is located is the rotation axis P. The crossing angle (relative angle) θ2 between the surface of the arm 44 that comes into contact with the fulcrum member 42 after the assembly of the moving member 30 to the fixed member 20 and the circle C is made larger.

アーム４４は、図２に示すように、アーム４４の長手方向一端部（車両前方側端部、近傍を含む）４４ａに、常時、バネ部材４３のバネ力Ｆａがかけられている。
アーム４４は、アーム４４の長手方向中間部４４ｂで支点部材４２に支持されている（載っている）。アーム４４の長手方向中間部４４ｂは、長手方向一端部４４ａ（バネ係合部４４ｆが設けられる部分）と長手方向他端部４４ｃ（ベース４１のアーム連結部４１ｂと連結される部分）との間にある部分である。
アーム４４は、アーム４４の長手方向他端部（車両後方側端部、近傍を含む）４４ｃでベース４１のアーム連結部４１ｂに回動可能に連結されている。アーム４４の長手方向他端部４４ｃは、回動部材３０の固定部材２０に対する開閉位置によらず、回動軸芯Ｐよりも車両後方に位置する。アーム４４の長手方向他端部４４ｃとベース４１のアーム連結部４１ｂとの連結は、アーム４４の長手方向他端部４４ｃとベース４１のアーム連結部４１ｂとの一方に円形穴を設け、アーム４４の長手方向他端部４４ｃとベース４１のアーム連結部４１ｂとの他方に前記円形穴に差し込まれる円柱ピンを設けることで行なわれる。アーム４４のベース４１に対する回動軸芯Ｐ１は、回動部材３０の回動軸芯Ｐと平行である。 As shown in FIG. 2, the arm 44 is always subjected to the spring force Fa of the spring member 43 on one end in the longitudinal direction of the arm 44 (including the vehicle front side end and the vicinity) 44 a.
The arm 44 is supported by (supported on) the fulcrum member 42 at a longitudinal intermediate portion 44 b of the arm 44. The longitudinal intermediate portion 44b of the arm 44 is between the longitudinal one end 44a (the portion where the spring engaging portion 44f is provided) and the longitudinal other end 44c (the portion connected to the arm connecting portion 41b of the base 41). It is a part in.
The arm 44 is rotatably connected to the arm connecting portion 41 b of the base 41 at the other longitudinal end portion (including the vehicle rear side end portion and the vicinity thereof) 44 c of the arm 44. The other end 44c in the longitudinal direction of the arm 44 is positioned behind the rotation axis P, regardless of the opening / closing position of the rotation member 30 with respect to the fixed member 20. For the connection between the other longitudinal end portion 44c of the arm 44 and the arm connecting portion 41b of the base 41, a circular hole is provided in one of the other end portion 44c of the arm 44 in the longitudinal direction and the arm connecting portion 41b of the base 41. This is performed by providing a cylindrical pin inserted into the circular hole on the other of the other end 44c in the longitudinal direction and the arm connecting portion 41b of the base 41. A rotation axis P <b> 1 with respect to the base 41 of the arm 44 is parallel to the rotation axis P of the rotation member 30.

（ｉ）アーム４４の長手方向一端部４４ａにばね部材４３のばね力Ｆａがかけられている。また、（ｉｉ）アーム４４が長手方向中間部４４ｂで支点部材４２に支持されている。また、（ｉｉｉ）アーム４４が長手方向他端部４４ｃでベース４１に回動可能に連結されている。（ｉ）〜（ｉｉｉ）により、てこの原理で、ばね部材４３のばね力Ｆａがかかるアーム４４位置が力点、支点部材４２に支持されるアーム４４位置が支点、ベース４１のアーム連結部４１ｂに連結されるアーム４２位置が作用点となり、ベース４１のアーム連結部４１ｂに上方の力Ｆｂが働く。力Ｆｂは、回動部材３０に回動軸芯Ｐまわりの閉方向モーメントＭ２を発生させる荷重である。力Ｆｂにより回動部材３０に回動軸芯Ｐまわりの閉方向モーメント（回転モーメント）Ｍ２が作用する。 (I) The spring force Fa of the spring member 43 is applied to one end 44 a in the longitudinal direction of the arm 44. (Ii) The arm 44 is supported by the fulcrum member 42 at the longitudinal intermediate portion 44b. (Iii) The arm 44 is rotatably connected to the base 41 at the other end 44c in the longitudinal direction. According to (i) to (iii), on the principle of the lever, the position of the arm 44 to which the spring force Fa of the spring member 43 is applied is the power point, the position of the arm 44 supported by the fulcrum member 42 is the fulcrum, and The position of the arm 42 to be connected becomes the point of action, and an upward force Fb acts on the arm connecting portion 41 b of the base 41. The force Fb is a load that causes the rotating member 30 to generate a closing direction moment M2 around the rotation axis P. A closing direction moment (rotational moment) M2 around the rotation axis P acts on the rotation member 30 by the force Fb.

アーム４４が長手方向他端部４４ｃで回動部材３０に固定して設けられるベース４１に連結されており、また、支点部材４２が固定部材２０に固定して設けられているため、回動部材３０が固定部材２０に対して閉位置３０ａから開位置３０ｂ側に移動するにつれて、支点部材４２がアーム４４に対して長手方向他端部４４ｃ側（車両後方側）から長手方向一端部４４ａ側（車両前方側）に移動（摺動）する。すなわち、アーム４４の、支点部材４２に支持される位置（てこの原理における支点の位置）は、図５、図６、図７に順に示すように、回動部材３０が固定部材２０に対して閉位置３０ａから開位置３０ｂ側に移動するにつれて、アーム４４の長手方向他端部４４ｃ側から長手方向一端部４４ａ側に移動する。このため、力Ｆｂは、図５、図６、図７に順に示すように、回動部材３０が閉位置３０ａから開位置３０ｂ側に移動するにつれて滑らかに徐々に小さくなる。よって、閉方向モーメント発生機構４０により回動部材３０に作用する閉方向モーメントＭ２は、図５、図６、図７に順に示すように、回動部材３０が閉位置３０ａから開位置３０ｂ側に移動するにつれて滑らかに徐々に小さくなる。 Since the arm 44 is connected to a base 41 fixed to the rotating member 30 at the other end 44c in the longitudinal direction, and the fulcrum member 42 is fixed to the fixing member 20, the rotating member As 30 moves from the closed position 30 a to the open position 30 b relative to the fixed member 20, the fulcrum member 42 moves from the other longitudinal end 44 c side (vehicle rear side) to the longitudinal one end 44 a side (on the vehicle rear side). Move (slide) to the front of the vehicle. That is, the position of the arm 44 supported by the fulcrum member 42 (the position of the fulcrum in the lever principle) is such that the rotating member 30 is in relation to the fixed member 20 as shown in FIG. 5, FIG. 6, and FIG. As it moves from the closed position 30a to the open position 30b, the arm 44 moves from the longitudinal other end 44c to the longitudinal one end 44a. For this reason, the force Fb gradually and gradually decreases as the rotating member 30 moves from the closed position 30a to the open position 30b as shown in FIG. 5, FIG. 6, and FIG. Therefore, the closing direction moment M2 applied to the rotating member 30 by the closing direction moment generating mechanism 40 is such that the rotating member 30 moves from the closed position 30a to the open position 30b side as shown in FIGS. As it moves, it gradually decreases gradually.

回動部材３０に作用している開方向モーメントＭ１の大きさと、閉方向モーメント発生機構４０により回動部材３０に作用する閉方向モーメントＭ２の大きさとの関係は、以下のようになっている。
（ａ）回動部材３０が、閉位置３０ａと開位置３０ｂとの間に位置する所定中間位置３０ｃと、閉位置３０ａと、の間にあるとき、閉方向モーメントＭ２の大きさが開方向モーメントＭ１の大きさより大きい。
（ｂ）回動部材３０が、所定中間位置３０ｃにあるとき、閉方向モーメントＭ２の大きさと開方向モーメントＭ１の大きさとが等しい（つり合っている）。
（ｃ）回動部材３０が、所定中間位置３０ｃと開位置３０ｂとの間にあるとき、開方向モーメントＭ１の大きさが閉方向モーメントＭ２の大きさより大きい。 The relationship between the magnitude of the opening direction moment M1 acting on the rotating member 30 and the magnitude of the closing direction moment M2 acting on the rotating member 30 by the closing direction moment generating mechanism 40 is as follows.
(A) When the rotating member 30 is between the predetermined intermediate position 30c located between the closed position 30a and the open position 30b and the closed position 30a, the magnitude of the closing direction moment M2 is the opening direction moment. It is larger than the size of M1.
(B) When the rotating member 30 is at the predetermined intermediate position 30c, the magnitude of the closing direction moment M2 and the magnitude of the opening direction moment M1 are equal (balanced).
(C) When the rotating member 30 is between the predetermined intermediate position 30c and the open position 30b, the magnitude of the opening direction moment M1 is larger than the magnitude of the closing direction moment M2.

つぎに、本発明実施例の作用を説明する。
アーム４４の回動範囲を規制する回動規制部４１ｆが設けられているため、回動部材３０を固定部材２０に組付けるときに組付作業者がアーム４４を手で支えなくても、回動部材３０を固定部材２０に組付けたときにアーム４４を支点部材４２に対して正規の位置に（閉方向モーメント発生機構４０が正常に作動する位置に）組付けることができる。よって、閉方向モーメント発生機構４０が設けられている場合であっても、回動部材３０の固定部材２０への組付け作業の困難化を招くことを抑制できる。 Next, the operation of the embodiment of the present invention will be described.
Since the rotation restricting portion 41f for restricting the rotation range of the arm 44 is provided, the rotation member 30 can be rotated even if the assembling operator does not support the arm 44 by hand when the rotating member 30 is assembled to the fixed member 20. When the moving member 30 is assembled to the fixed member 20, the arm 44 can be assembled to a normal position with respect to the fulcrum member 42 (at a position where the closing direction moment generating mechanism 40 operates normally). Therefore, even when the closing direction moment generating mechanism 40 is provided, it is possible to suppress the difficulty in assembling the rotating member 30 to the fixed member 20.

接触開始面４４ｇと、回動軸芯Ｐを中心とし該中心から支点部材４２が位置する位置までを半径とする円Ｃとの交差角度θ１が、回動部材３０の固定部材２０への組付け完了後に支点部材４２と接触するアーム４４の面と、円Ｃとの交差角度θ２よりも、大とされているため、交差角度θ１が交差角度θ２と同じかそれより小とされている場合と異なり、回動部材３０の固定部材２０への組付け時に接触開始面４４ｇがアーム４４を支点部材４２に対して正規の位置に（閉方向モーメント発生機構４０が正常に作動する位置に）導くガイドとして働き得る。そのため、回動部材３０を固定部材２０に組付けるときに組付作業者がアーム４４を手で支えなくても、回動部材３０を固定部材２０に組付けたときにアーム４４を支点部材４２に対して正規の位置に（閉方向モーメント発生機構が正常に作動する位置に）より確実に組付けることができる。 The intersection angle θ1 between the contact start surface 44g and the circle C having a radius from the center to the position where the fulcrum member 42 is located is the assembly of the rotating member 30 to the fixed member 20. Since the crossing angle θ2 between the surface of the arm 44 that contacts the fulcrum member 42 after completion and the circle C is larger than the crossing angle θ1, the crossing angle θ1 is equal to or smaller than the crossing angle θ2. In contrast, when the rotating member 30 is assembled to the fixed member 20, the contact start surface 44g guides the arm 44 to a normal position with respect to the fulcrum member 42 (to a position where the closing direction moment generation mechanism 40 operates normally). Can work as. Therefore, even when the assembling operator does not support the arm 44 by hand when the rotating member 30 is assembled to the fixed member 20, the arm 44 is supported by the fulcrum member 42 when the rotating member 30 is assembled to the fixed member 20. As a result, it can be more reliably assembled at a normal position (at a position where the closing direction moment generation mechanism operates normally).

回動部材３０に作用している開方向モーメントＭ１の大きさと、閉方向モーメント発生機構４０により回動部材３０に作用する閉方向モーメントＭ２の大きさとの関係が、（ａ）回動部材３０が所定中間位置３０ｃと閉位置３０ａとの間にあるとき、閉方向モーメントＭ２の大きさが開方向モーメントＭ１の大きさより大きく、（ｂ）回動部材３０が所定中間位置３０ｃにあるとき、閉方向モーメントＭ２の大きさと開方向モーメントＭ１の大きさとが等しく、（ｃ）回動部材３０が所定中間位置３０ｃと開位置３０ｂとの間にあるとき、開方向モーメントＭ１の大きさが閉方向モーメントＭ２の大きさより大きい、となるようにされているため、開位置３０ｂにある回動部材３０を手動で所定中間位置３０ｃを越える位置まで閉位置３０ａ側に移動させるだけで、回動部材３０を閉位置３０ａ側に自動で移動させることができる。 The relationship between the magnitude of the opening direction moment M1 acting on the turning member 30 and the magnitude of the closing direction moment M2 acting on the turning member 30 by the closing direction moment generating mechanism 40 is as follows. When it is between the predetermined intermediate position 30c and the closed position 30a, the magnitude of the closing direction moment M2 is larger than the magnitude of the opening direction moment M1, and (b) when the rotating member 30 is at the predetermined intermediate position 30c, the closing direction When the magnitude of the moment M2 is equal to the magnitude of the opening direction moment M1, and (c) when the rotating member 30 is between the predetermined intermediate position 30c and the opening position 30b, the magnitude of the opening direction moment M1 is equal to the closing direction moment M2. Therefore, the rotating member 30 at the open position 30b is manually closed to the position exceeding the predetermined intermediate position 30c. Only by moving the rotation member 30 can be moved automatically to the closed position 30a side.

閉方向モーメント発生機構４０による閉方向モーメントＭ２が、閉位置３０ａと開位置３０ｂとの間の全領域で回動部材３０に作用しているため、閉位置３０ａと開位置３０ｂとの間の一部の領域でのみ回動部材３０に作用する場合に比べて、回動部材３０の開閉操作の際に操作荷重が急変することを抑制できる。 Since the closing direction moment M2 generated by the closing direction moment generation mechanism 40 acts on the rotating member 30 in the entire region between the closing position 30a and the opening position 30b, the distance between the closing position 30a and the opening position 30b is one. Compared with the case where it acts on the rotating member 30 only in the region of the portion, it is possible to suppress the operation load from changing suddenly when the rotating member 30 is opened and closed.

閉方向モーメント発生機構４０がアーム４４にバネ力をかけるバネ部材４３を備えているため、開位置３０ｂにある回動部材３０を閉位置３０ａ側に回動させるためのモータは不要である。そのため、モータ及びその他配線等が不要でありコスト上有利である。 Since the closing direction moment generating mechanism 40 includes the spring member 43 that applies a spring force to the arm 44, a motor for rotating the rotating member 30 at the open position 30b toward the closed position 30a is not necessary. This eliminates the need for a motor and other wiring, and is advantageous in terms of cost.

閉方向モーメント機構４０がてこの原理を利用しているため、比較的簡単な構造で、回動部材３０に閉方向モーメントＭ２を作用させることができる。 Since the closing direction moment mechanism 40 uses the lever principle, the closing direction moment M2 can be applied to the rotating member 30 with a relatively simple structure.

閉方向モーメント機構４０がてこの原理を利用しているため、比較的簡単な構造で、閉方向モーメントＭ２の大きさを、回動部材３０が閉位置３０ａから開位置３０ｂ側に移動するにつれて滑らかに徐々に小さくすることができる。 Since the closing direction moment mechanism 40 uses the lever principle, the magnitude of the closing direction moment M2 is smoothed as the rotating member 30 moves from the closing position 30a to the opening position 30b with a relatively simple structure.

アーム４４の、支点部材４２に支持される位置が、回動部材３０が固定部材２０に対して閉位置３０ａから開位置３０ｂ側に移動するにつれて、アーム４４の長手方向他端部４４ｃ側から長手方向一端部４４ａ側に移動するため、てこの原理における支点が移動する。そのため、回動部材３０が固定部材２０に対して閉位置３０ａから開位置３０ｂ側に移動するにつれて、てこの原理における力点から支点までの距離が徐々に小さくなり、てこの原理における支点から作用点までの距離が徐々に大きくなる。したがって、回動部材３０が固定部材２０に対して閉位置３０ａから開位置３０ｂ側に移動するにつれて、アーム４４からベース４１にてこの原理を利用して付与される荷重（作用点における荷重）を徐々に小さくすることができる。よって、回動部材３０が固定部材２０に対して閉位置３０ａから開位置３０ｂ側に移動するにつれて、閉方向モーメント発生機構４０により回動部材３０に作用する閉方向モーメントＭ２の大きさを滑らかに徐々に小さくすることができる。 The position of the arm 44 supported by the fulcrum member 42 is longer from the other end 44c in the longitudinal direction of the arm 44 as the rotating member 30 moves from the closed position 30a to the open position 30b with respect to the fixed member 20. Since it moves to the direction one end 44a side, the fulcrum in the lever principle moves. Therefore, as the rotating member 30 moves from the closed position 30a to the open position 30b with respect to the fixed member 20, the distance from the power point to the fulcrum in the lever principle gradually decreases, and the point from the lever in the lever principle to the action point. The distance to gradually increases. Therefore, as the rotating member 30 moves from the closed position 30a to the open position 30b with respect to the fixed member 20, the load applied by using this principle from the arm 44 to the base 41 (load at the point of application) is applied. Can be gradually reduced. Therefore, as the turning member 30 moves from the closed position 30a to the open position 30b with respect to the fixed member 20, the magnitude of the closing direction moment M2 acting on the turning member 30 by the closing direction moment generating mechanism 40 is made smoother. Can be gradually reduced.

回動部材３０に作用する開方向モーメントＭ１が、回動部材３０が閉位置３０ａから開位置３０ｂ側に移動するにつれて滑らかに徐々に大きくなっている。また、閉方向モーメント発生機構４０により回動部材３０に作用する閉方向モーメントＭ２が、回動部材３０が閉位置３０ａから開位置３０ｂ側に移動するにつれて滑らかに徐々に小さくなっている。このように開方向モーメントＭ１と閉方向モーメントＭ２のバランスが徐々に滑らかに変化するため、回動部材３０を開ける際に急な荷重変化が発生することを抑制できる。 The opening direction moment M1 acting on the rotating member 30 gradually and gradually increases as the rotating member 30 moves from the closed position 30a to the open position 30b. Further, the closing direction moment M2 acting on the rotating member 30 by the closing direction moment generating mechanism 40 gradually decreases gradually as the rotating member 30 moves from the closed position 30a to the open position 30b. As described above, since the balance between the opening direction moment M1 and the closing direction moment M2 changes gradually and smoothly, it is possible to prevent a sudden load change from occurring when the rotating member 30 is opened.
