（作用・効果）
先ず、閉止位置に配置された開閉部材１８を開放させる動作について説明する。 (Action / Effect)
First, an operation of opening the opening / closing member 18 arranged at the closed position will be described.

図１、図２に示されるように、開閉部材１８の閉止位置では、開閉部材１８が本体２０の開口部２２を閉止しており、バネ部材５０の付勢力Ｆの分力Ｆ１が、アーム部材４０の回転中心に向ってアーム部材４０を付勢して係合部４２Ｂを被係合部５２Ａに係合させている。これにより、開閉部材１８は閉止位置で保持されている。そして、図１１（Ａ）に示されるように、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの一端部に配置される。   As shown in FIGS. 1 and 2, when the opening / closing member 18 is closed, the opening / closing member 18 closes the opening 22 of the main body 20, and the component force F <b> 1 of the biasing force F of the spring member 50 is the arm member. The arm member 40 is urged toward the rotation center 40 to engage the engaging portion 42B with the engaged portion 52A. Thereby, the opening / closing member 18 is held at the closed position. 11A, the shaft portion 30 inserted into the long hole 42A of the arm portion 42 is disposed at one end portion of the long hole 42A.

図３、図４に示されるように、ユーザがカップホルダー１２を使用しようとして、開閉部材１８を開方向へ回転移動させようとすると、リブ部材３２にエンボス４４（図１２参照）が押されてアーム部材４０が開閉部材１８と一体に回転する。アーム部材４０が回転することで、係合部４２Ｂを構成する傾斜面が、被係合部５２Ａを構成する傾斜面を押圧することで、アーム部４２が非係合方向に移動し、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの一端部から他端部に移動する（図１１（Ｂ）参照）。これにより、係合部４２Ｂと被係合部５２Ａとの係合が解除され、係合部４２Ｂは被係合部材５２の案内部５２Ｃへ移行する。   As shown in FIGS. 3 and 4, when the user tries to use the cup holder 12 and rotates the opening / closing member 18 in the opening direction, the emboss 44 (see FIG. 12) is pushed by the rib member 32. The arm member 40 rotates integrally with the opening / closing member 18. When the arm member 40 rotates, the inclined surface constituting the engaging portion 42B presses the inclined surface constituting the engaged portion 52A, so that the arm portion 42 moves in the non-engaging direction, and the arm portion The shaft portion 30 inserted into the long hole 42A of 42 moves from one end portion of the long hole 42A to the other end portion (see FIG. 11B). Thereby, the engagement between the engaging portion 42B and the engaged portion 52A is released, and the engaging portion 42B moves to the guide portion 52C of the engaged member 52.

図５、図６に示されるように、係合部４２Ｂが案内部５２Ｃに案内され、バネ部材５０の付勢力Ｆがアーム部材４０の回転中心に向うまで、ユーザは開閉部材１８を開放させる。この状態では、アーム部材４０には、アーム部材４０を回転させるモーメントが発生していないため、開閉部材１８はこの所定の開閉位置（以下停止位置と言う）で停止する。そして、図１１（Ｃ）に示されるように、アーム部材４０がバネ部材５０の付勢力によって軸部３０に向って付勢されることで、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの一端部に移動する。   As shown in FIGS. 5 and 6, the user opens the opening / closing member 18 until the engaging portion 42 </ b> B is guided by the guide portion 52 </ b> C and the urging force F of the spring member 50 is directed toward the rotation center of the arm member 40. In this state, since no moment is generated in the arm member 40 to rotate the arm member 40, the opening / closing member 18 stops at this predetermined opening / closing position (hereinafter referred to as a stop position). 11C, the arm member 40 is urged toward the shaft portion 30 by the urging force of the spring member 50, so that the shaft portion inserted into the elongated hole 42A of the arm portion 42. 30 moves to one end of the long hole 42A.

図７、図８に示されるように、ユーザが停止位置の開閉部材１８を開方向へ回転移動させると、バネ部材５０に分力Ｆ２が生じる。この分力Ｆ２が、アーム部材４０に開閉部材１８の開方向に回転させるモーメントを発生させる。これにより、操作力が軽減された（又は無くなった）状態で、係合部４２Ｂが案内部５２Ｃに案内され、開閉部材１８が開方向へ回転移動する。そして、図１１（Ｄ）に示されるように、係合部４２Ｂが案内部５２Ｃにより軸部３０に向って押圧されることで、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの他端部に移動する。   As shown in FIGS. 7 and 8, when the user rotates the opening / closing member 18 at the stop position in the opening direction, a component force F <b> 2 is generated in the spring member 50. This component force F2 causes the arm member 40 to generate a moment that rotates the opening / closing member 18 in the opening direction. Thereby, in a state where the operating force is reduced (or lost), the engaging portion 42B is guided by the guide portion 52C, and the opening / closing member 18 rotates in the opening direction. 11D, the engaging portion 42B is pressed toward the shaft portion 30 by the guide portion 52C, so that the shaft portion 30 inserted into the long hole 42A of the arm portion 42 is It moves to the other end of the long hole 42A.

図９、図１０に示されるように、開口部２２が開放された開閉部材１８が開放位置に移動すると、バネ部材５０の付勢力Ｆの分力Ｆ１が、アーム部材４０の回転中心に向ってアーム部材４０を付勢して係合部４２Ｂを被係合部５２Ｂに係合させている。これにより、開閉部材１８は開放位置で保持されている。そして、図１１（Ｅ）に示されるように、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの一端部に移動する。   As shown in FIGS. 9 and 10, when the opening / closing member 18 with the opening 22 opened moves to the open position, the component force F <b> 1 of the urging force F of the spring member 50 moves toward the rotation center of the arm member 40. The arm member 40 is biased to engage the engaging portion 42B with the engaged portion 52B. Thereby, the opening / closing member 18 is held in the open position. Then, as shown in FIG. 11 (E), the shaft portion 30 inserted into the long hole 42A of the arm portion 42 moves to one end portion of the long hole 42A.

次ぎに、開放位置に配置された開閉部材１８を閉止させる動作について説明する。   Next, an operation for closing the opening / closing member 18 disposed at the open position will be described.

図９、図１０に示されるように、開閉部材１８の開放位置では、開閉部材１８が本体２０の開口部２２を開放しており、バネ部材５０の付勢力Ｆの分力Ｆ１が、アーム部材４０の回転中心に向ってアーム部材４０を付勢して係合部４２Ｂを被係合部５２Ｂに係合させている。これにより、開閉部材１８は開放位置で保持されている。そして、図１１（Ｅ）に示されるように、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの一端部に配置される。   9 and 10, when the opening and closing member 18 is in the open position, the opening and closing member 18 opens the opening 22 of the main body 20, and the component force F1 of the biasing force F of the spring member 50 is the arm member. The arm member 40 is urged toward the rotation center 40 to engage the engaging portion 42B with the engaged portion 52B. Thereby, the opening / closing member 18 is held in the open position. Then, as shown in FIG. 11E, the shaft portion 30 inserted into the long hole 42A of the arm portion 42 is disposed at one end portion of the long hole 42A.

図７、図８に示されるように、ユーザがカップホルダー１２を収納しようとして、開閉部材１８を閉方向へ回転移動させようとすると、リブ部材３２にエンボス４４（図１２参照）が押されてアーム部材４０が開閉部材１８と一体に回転する。アーム部材４０が回転することで、係合部４２Ｂを構成する傾斜面が、被係合部５２Ｂを構成する傾斜面を押圧することで、アーム部４２が非係合方向に移動し、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの一端部から他端部に移動する（図１１（Ｄ）参照）。これにより、係合部４２Ｂと被係合部５２Ｂとの係合が解除され、係合部４２Ｂは被係合部材５２の案内部５２Ｃへ移行する。   As shown in FIGS. 7 and 8, when the user tries to store the cup holder 12 and rotates the opening / closing member 18 in the closing direction, the emboss 44 (see FIG. 12) is pushed by the rib member 32. The arm member 40 rotates integrally with the opening / closing member 18. When the arm member 40 rotates, the inclined surface constituting the engaging portion 42B presses the inclined surface constituting the engaged portion 52B, so that the arm portion 42 moves in the non-engaging direction, and the arm portion The shaft portion 30 inserted into the long hole 42A of 42 moves from one end portion of the long hole 42A to the other end portion (see FIG. 11D). Thereby, the engagement between the engaging portion 42B and the engaged portion 52B is released, and the engaging portion 42B moves to the guide portion 52C of the engaged member 52.

図５、図６に示されるように、係合部４２Ｂが案内部５２Ｃに案内され、バネ部材５０の付勢力Ｆがアーム部材４０の回転中心に向うまで、ユーザは開閉部材１８を閉止させる。この状態では、アーム部材４０には、アーム部材４０を回転させるモーメントが発生していないため、開閉部材１８はこの停止位置で停止する。そして、図１１（Ｃ）に示されるように、アーム部材４０がバネ部材５０の付勢力によって軸部３０に向って付勢されることで、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの一端部に移動する。   As shown in FIGS. 5 and 6, the user closes the opening / closing member 18 until the engaging portion 42 </ b> B is guided by the guide portion 52 </ b> C and the urging force F of the spring member 50 is directed toward the rotation center of the arm member 40. In this state, since no moment is generated in the arm member 40 to rotate the arm member 40, the opening / closing member 18 stops at this stop position. 11C, the arm member 40 is urged toward the shaft portion 30 by the urging force of the spring member 50, so that the shaft portion inserted into the elongated hole 42A of the arm portion 42. 30 moves to one end of the long hole 42A.

図３、図４に示されるように、ユーザが停止位置の開閉部材１８を閉方向へ回転移動させると、バネ部材５０に分力Ｆ２が生じる。この分力Ｆ２が、アーム部材４０に開閉部材１８の閉方向に回転させるモーメントを発生させる。これにより、操作力が軽減された（又は無くなった）状態で、係合部４２Ｂが案内部５２Ｃに案内され、開閉部材１８が閉方向へ回転移動する。そして、図１１（Ｂ）に示されるように、係合部４２Ｂが案内部５２Ｃにより軸部３０に向って押圧されることで、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの他端部に移動する。   As shown in FIGS. 3 and 4, when the user rotates the opening / closing member 18 at the stop position in the closing direction, a component force F <b> 2 is generated in the spring member 50. This component force F2 causes the arm member 40 to generate a moment for rotating the opening / closing member 18 in the closing direction. Thereby, the engaging part 42B is guided to the guide part 52C in a state where the operating force is reduced (or lost), and the opening / closing member 18 rotates in the closing direction. Then, as shown in FIG. 11 (B), when the engaging portion 42B is pressed toward the shaft portion 30 by the guide portion 52C, the shaft portion 30 inserted into the elongated hole 42A of the arm portion 42 is It moves to the other end of the long hole 42A.

図１、図２に示されるように、開口部２２が閉止されて開閉部材１８が閉止位置に移動すると、バネ部材５０の付勢力Ｆの分力Ｆ１が、アーム部材４０の回転中心に向ってアーム部材４０を付勢して係合部４２Ｂを被係合部５２Ｂに係合させている。これにより、開閉部材１８は閉止位置で保持されている。そして、図１１（Ａ）に示されるように、アーム部４２の長孔４２Ａに挿入された軸部３０は、長孔４２Ａの一端部に移動する。   As shown in FIGS. 1 and 2, when the opening 22 is closed and the opening / closing member 18 moves to the closed position, the component force F <b> 1 of the urging force F of the spring member 50 moves toward the rotation center of the arm member 40.
