次に、組み付けについて説明する。
まず、図１に示すように、取付孔１２ａに取付孔２３ａを対応させた後、例えば、アウターケース１１の外側から図示を省略した取付ビスを取付孔１２ａへ挿通して取付孔２３ａに螺合させることにより、ダンパー２１をアウターケース１１に取り付ける。
そして、グローブボックス本体４１の下端部分をアウターケース１１に回動可能に取り付けた後、グローブボックス本体４１の装着孔５４側を窄めてアウターケース１１内へ挿入し、装着孔５４を歯車２４に対向させてグローブボックス本体４１を窄める力を除くと、グローブボックス本体４１の右側板４２が自身の弾性で元の状態へ復帰することによって円盤状フランジ部３３が装着孔５４を通過し、軸部３２が装着孔５４内に位置するとともに、歯車２４がラック７１の延長線上に位置してガイド部材５１内に位置するようになる。 Next, assembly will be described.
First, as shown in FIG. 1, after the mounting hole 23a is made to correspond to the mounting hole 12a, for example, a mounting screw (not shown) is inserted into the mounting hole 12a from the outside of the outer case 11 and screwed into the mounting hole 23a. As a result, the damper 21 is attached to the outer case 11.
Then, after the lower end portion of the glove box body 41 is rotatably attached to the outer case 11, the mounting hole 54 side of the glove box body 41 is narrowed and inserted into the outer case 11, and the mounting hole 54 is connected to the gear 24. When the force that constricts the glove box body 41 is removed, the right side plate 42 of the glove box body 41 returns to its original state by its own elasticity, so that the disk-like flange portion 33 passes through the mounting hole 54, The shaft portion 32 is positioned in the mounting hole 54, and the gear 24 is positioned on the extension line of the rack 71 and positioned in the guide member 51.

この状態でグローブボックス本体４１をアウターケース１１内へ押し込むと、軸部３２がガイド溝５３内を移動することにより、歯車２４と円盤状フランジ部３３とがガイド溝形成部分５２ｃを介して対向し、歯車２４がラック７１に噛み合った後、軸部３２がストッパ６１に乗り上がってガイド溝形成部分５２ｃを拡開させることによってストッパ６１を軸部３２が乗り越え、図５に示すように、組み立てることができる。   When the glove box body 41 is pushed into the outer case 11 in this state, the shaft portion 32 moves in the guide groove 53, so that the gear 24 and the disc-shaped flange portion 33 face each other via the guide groove forming portion 52c. After the gear 24 meshes with the rack 71, the shaft portion 32 rides on the stopper 61 and widens the guide groove forming portion 52c, so that the shaft portion 32 gets over the stopper 61, and is assembled as shown in FIG. Can do.

次に、動作について説明する。
まず、開放状態のグローブボックス本体４１を閉じる場合、グローブボックス本体４１を、回動軸を中心にして回動させると、軸部３２がガイド溝５３内を移動することにより、グローブボックス本体４１を閉じることができる。
このようにしてグローブボックス本体４１を閉じる場合、図示を省略したノブまたはボタンに連動したロック機構で、グローブボックス本体４１を閉じた状態にロックする。
そして、円盤状フランジ部３３がガイド部材５１のガイド溝形成部分５２ｃを介して歯車２４と常時対向している。 Next, the operation will be described.
First, when closing the opened glove box body 41, when the glove box body 41 is rotated about the rotation axis, the shaft portion 32 moves in the guide groove 53, thereby causing the glove box body 41 to move. Can be closed.
When the glove box main body 41 is closed in this way, the glove box main body 41 is locked in a closed state by a lock mechanism interlocked with a knob or button not shown.
The disc-shaped flange portion 33 always faces the gear 24 via the guide groove forming portion 52 c of the guide member 51.

次に、閉じている状態のグローブボックス本体４１を開ける場合、ノブまたはボタンを操作することによってロック機構がアンロック状態になるので、グローブボックス本体４１は、回動軸を中心にして自重で回動し、軸部３２がガイド溝５３内を移動することにより、開放する。
そして、軸部３２がストッパ６１に衝合することにより、開放位置に停止する。
このようにしてグローブボックス本体４１を開ける場合、ダンパー２１の制動機能が働いてグローブボックス本体４１はゆっくりと回動する。
そして、円盤状フランジ部３３がガイド部材５１のガイド溝形成部分５２ｃを介して歯車２４と常時対向している。 Next, when the closed glove box body 41 is opened, the lock mechanism is unlocked by operating the knob or button, so that the glove box body 41 rotates with its own weight around the rotation axis. When the shaft 32 moves in the guide groove 53, the shaft 32 is released.
Then, when the shaft portion 32 abuts on the stopper 61, the shaft portion 32 stops at the open position.
When the glove box body 41 is opened in this way, the braking function of the damper 21 works and the glove box body 41 rotates slowly.
The disc-shaped flange portion 33 always faces the gear 24 via the guide groove forming portion 52 c of the guide member 51.

上述したように、この発明の第１実施例によれば、ダンパー２１の歯車２４と被ガイド部材３１の円盤状フランジ部３３とがガイド部材５１（ガイド溝形成部分５２ｃ）を介して対向しているので、歯車２４に歯車２４の軸方向の力が作用しても、歯車２４とラック７１との噛み合いが外れなくなり、グローブボックス本体４１の移動を確実に制動することができる。
そして、円盤状フランジ部３３がガイド部材５１（ガイド溝形成部分５２ｃ）と常時対向しているので、歯車２４とラック７１との噛み合いが常に外れなくなり、グローブボックス本体４１の移動を確実に制動することができる。 As described above, according to the first embodiment of the present invention, the gear 24 of the damper 21 and the disc-shaped flange portion 33 of the guided member 31 are opposed to each other via the guide member 51 (guide groove forming portion 52c). Therefore, even if the axial force of the gear 24 acts on the gear 24, the gear 24 and the rack 71 are not disengaged, and the movement of the glove box body 41 can be reliably braked.
Since the disc-shaped flange portion 33 always faces the guide member 51 (guide groove forming portion 52c), the meshing between the gear 24 and the rack 71 is not always released, and the movement of the glove box body 41 is reliably braked. be able to.

さらに、ガイド部材５１が、ガイド溝５３に軸部３２を係合させる装着孔５４を、グローブボックス本体４１の移動設定範囲Ｒ外に有しているので、グローブボックス本体４１の移動設定範囲Ｒ内において歯車２４とラック７１との噛み合いが外れなくなり、グローブボックス本体４１の移動設定範囲Ｒ内におけるグローブボックス本体４１の移動を確実に制動することができる。
そして、ガイド部材５１がグローブボックス本体４１の移動設定範囲Ｒを規定するストッパ６１を有しているので、グローブボックス本体４１の移動設定範囲Ｒをストッパ６１で規定することができる。 Further, since the guide member 51 has the mounting hole 54 for engaging the shaft portion 32 with the guide groove 53 outside the movement setting range R of the glove box body 41, Therefore, the meshing between the gear 24 and the rack 71 is not released, and the movement of the glove box body 41 within the movement setting range R of the glove box body 41 can be reliably braked.
Since the guide member 51 has the stopper 61 that defines the movement setting range R of the glove box body 41, the movement setting range R of the glove box body 41 can be defined by the stopper 61.

図６はこの発明の第２実施例である制動機構のラックおよびガイド部材などを左側から見た一部を省略した図であり、図１〜図５と同一または相当部分に同一符号を付して説明を省略する。
この図６は、第１実施例の図３に対応する図である。 FIG. 6 is a partially omitted view of the rack and guide members of the braking mechanism according to the second embodiment of the present invention as viewed from the left side, and the same reference numerals are given to the same or corresponding parts as in FIGS. The description is omitted.
FIG. 6 corresponds to FIG. 3 of the first embodiment.

図６において、５５は被装着部としての装着用切欠を示し、被ガイド部材（３１）の円盤状フランジ部（３３）を挿入してガイド溝５３へ軸部（３２）を挿入するための装着用切欠５５が被装着部として右側板４２の端に設けられている。
なお、この第２実施例が第１実施例と異なるところは、装着孔（５４）に代えて装着用切欠５５を設けた点である。 In FIG. 6, reference numeral 55 denotes a mounting notch as a mounted portion, and a mounting for inserting the disc-shaped flange portion (33) of the guided member (31) and inserting the shaft portion (32) into the guide groove 53. A notch 55 is provided at the end of the right side plate 42 as a mounted portion.
The second embodiment differs from the first embodiment in that a mounting notch 55 is provided instead of the mounting hole (54).

この第２実施例における動作などは、第１実施例と同様になるので、説明を省略する。   Since the operation in the second embodiment is the same as that in the first embodiment, the description thereof is omitted.

この第２実施例においても、第１実施例と同様な効果を得ることができる。   In the second embodiment, the same effect as that of the first embodiment can be obtained.

上記した実施例では、本体としてのアウターケース１１にダンパー２１を取り付け、移動体としてのダッシュボード本体４１にガイド部材を設けた例を示したが、本体としてのアウターケースにガイド部材を設け、移動体としてのダッシュボード本体にダンパーを設けても、同様の効果を得ることができる。
また、回動軸を中心にして回動するダッシュボード本体４１を移動体の一例として示したが、本体に対して、例えば、付勢部材としてのスプリングで突出するように付勢され、プッシュ・プッシュ式のロック機構で収納位置にロックされる構成の横方向へ移動する引出式の移動体、例えば、自動車に設けられている灰皿などにも適用できることは言うまでもない。
さらに、ストッパ６１をガイド部材５１の部分に設けた例を示したが、移動体の移動範囲を設定できればよいので、本体と移動体との間に設けてもよい。 In the above-described embodiment, the damper 21 is attached to the outer case 11 as the main body, and the guide member is provided in the dashboard main body 41 as the moving body. However, the guide member is provided in the outer case as the main body and moved. Even if a damper is provided on the dashboard body as a body, the same effect can be obtained.
Further, the dashboard main body 41 that rotates about the rotation axis is shown as an example of the movable body. However, the main body 41 is biased so as to protrude with a spring as a biasing member, Needless to say, the present invention can also be applied to a drawer-type moving body that moves in the lateral direction in which the push-type locking mechanism is locked at the storage position, for example, an ashtray provided in an automobile.
Furthermore, although the example which provided the stopper 61 in the part of the guide member 51 was shown, since the movement range of a moving body should just be set, you may provide between a main body and a moving body.
