Description

ダンパー装置Damper device
　本発明は、例えば車両のグローブボックスなどに適用して、グローブボックスを開く時などの所定の動作時にダンパー作用を与えるダンパー装置に関する。 The present invention relates to a damper device that is applied to, for example, a glove box of a vehicle and exerts a damper action during a predetermined operation such as when opening the glove box.
　例えば車両のグローブボックスなどの開閉体には、開閉体が急激に開いたりすることを抑制するため、ダンパー装置が設けられることがある。このようなダンパー装置は、各種の機構のものが知られており、その１つとして、回転ダンパーを利用したものが知られている。回転ダンパーを利用したダンパー装置は、装置をコンパクト化しやすいという利点を有している。 For example, a damper device may be provided on an opening / closing body such as a glove box of a vehicle in order to prevent the opening / closing body from opening suddenly. As such a damper device, those having various mechanisms are known, and as one of them, one using a rotary damper is known. A damper device using a rotary damper has an advantage that the device can be easily made compact.
　回転ダンパーを利用したダンパー装置として、下記特許文献１には、第一パーツと、この第一パーツに回転又は相対的に回転可能に組み合わされた第二パーツと、両パーツ間に充填された粘性流体とを備え、この粘性流体により前記回転に制動力を作用させるように構成されると共に、前記第一パーツ及び第二パーツのいずれか一方にピニオン部を備えさせてなる回転ダンパー体と、この回転ダンパー体の前記第一パーツ及び第二パーツの他方に設けられた凹所に対する突所を備え、この凹所に突所を納めてこの回転ダンパー体を回転可能に支持する支持体とを備えてなり、この凹所及び突所に、前記ピニオン部に組み合わされるラック体の一方向に向けた移動又は相対的な移動時にこのラック体と同じ方向への回転ダンパー体の移動により係合し合うと共に、このラック体の他方向に向けた移動又は相対的な移動時にはこのラック体と同じ方向への回転ダンパー体の移動により係合を解く、係合部を形成させてなることを特徴とするダンパー装置が開示されている。 As a damper device using a rotary damper, the following Patent Document 1 describes a first part, a second part rotatably or relatively rotatably combined with the first part, and a viscosity filled between both parts. A rotating damper body provided with a fluid, configured to exert a braking force on the rotation by the viscous fluid, and having a pinion portion on either one of the first part and the second part, and the rotating damper body. A protrusion for a recess provided on the other side of the first part and the second part of the rotary damper body is provided, and a support that accommodates the recess and rotatably supports the rotary damper body is provided. The recesses and protrusions are engaged with each other by moving the rotating damper body in the same direction as the rack body when moving toward or relative to the rack body combined with the pinion portion. At the same time, when the rack body is moved in the other direction or relative to the rack body, the rotating damper body is moved in the same direction as the rack body to disengage the engagement, and an engaging portion is formed. The damper device is disclosed.
特許第５８３６２８１Patent No. 5836281
　しかしながら、上記特許文献１のダンパー装置では、ラック体の移動に伴って回転ダンパー体自体を支持体に対して移動させて、凹所と突所の係合及び係合解除をするようにしているので、ラック体の移動方向の反転時における係合解除状態から係合状態への切り替えを円滑に行い難く、制動力応答性が良好でないという問題があった。 However, in the damper device of Patent Document 1, the rotating damper body itself is moved with respect to the support as the rack body moves, so that the recesses and the protrusions are engaged and disengaged. Therefore, there is a problem that it is difficult to smoothly switch from the disengaged state to the engaged state when the rack body is reversed in the moving direction, and the braking force response is not good.
　したがって、本発明の目的は、ラック体の移動方向の反転時における制動力応答性の良好なダンパー装置を提供することにある。 Therefore, an object of the present invention is to provide a damper device having good braking force response when the rack body is reversed in the moving direction.

　前記回転ダンパーは、前記ピニオンギヤに連結されたロータと、粘性流体を介して前記ロータを囲み、前記ロータに対して相対回転可能に装着され、外周に前記大径ギヤを有するギヤハウジングとを有しており、
　前記ケースは、前記遊星ギヤを前記回転ダンパーの前記大径ギヤに歯合させた状態で前記大径ギヤの周方向に沿って所定距離移動可能に収容する収容部と、該収容部の内壁の一側に設けられ、前記遊星ギヤが当接したとき、その回転を規制する係合部と、前記収容部の内壁の前記一側に対向する他側に設けられ、前記遊星ギヤが当接した状態でその回転を許容する回転許容部とを有しており、
　前記ラック体が所定方向に移動するとき、前記ギヤハウジングの回転に伴って前記遊星ギヤが前記収容部の一側に移動し、前記係合部に係合して回転を規制され、前記ラック体が前記とは反対側に移動するとき、前記ギヤハウジングの回転に伴って前記遊星ギヤが前記収容部の他側に移動し、前記回転許容部に当接して回転を許容されるように構成されていることを特徴とする。 In order to achieve the above object, the damper device of the present invention is
A rack body having a rack gear formed along the length direction, a rotary damper having a pinion gear meshing with the rack gear and a large-diameter gear provided on the outer periphery, and a rotary damper having a large-diameter gear meshing with the large-diameter gear are arranged. A planetary gear and a case for slidably holding the rack body and rotatably accommodating the rotary damper and the planetary gear are provided.
The rotary damper has a rotor connected to the pinion gear and a gear housing that surrounds the rotor via a viscous fluid, is mounted so as to be rotatable relative to the rotor, and has the large-diameter gear on the outer circumference. And
The case includes an accommodating portion that accommodates the planetary gear so as to be movable a predetermined distance along the circumferential direction of the large-diameter gear in a state where the planetary gear is meshed with the large-diameter gear of the rotary damper, and an inner wall of the accommodating portion. The engaging portion provided on one side and restricting its rotation when the planetary gear comes into contact with the planetary gear and the other side of the inner wall of the accommodating portion facing the one side are brought into contact with the planetary gear. It has a rotation allowance part that allows the rotation in the state,
When the rack body moves in a predetermined direction, the planetary gear moves to one side of the accommodating portion with the rotation of the gear housing, engages with the engaging portion, and the rotation is restricted. The planetary gear moves to the other side of the accommodating portion as the gear housing rotates, and abuts on the rotation permitting portion to allow rotation. It is characterized by being.
　本発明によれば、ラック体が所定方向に移動するとき、ギヤハウジングの回転に伴って遊星ギヤが収容部の一側に移動し、係合部に係合して回転を規制されるので、遊星ギヤを介してギヤハウジングの回転が停止し、ギヤハウジングに対してロータが回転することにより、粘性流体を介してロータの回転に対して制動力が付与され、ラック体の移動に対する制動力が付与される。 According to the present invention, when the rack body moves in a predetermined direction, the planetary gear moves to one side of the accommodating portion as the gear housing rotates, and engages with the engaging portion to regulate the rotation. The rotation of the gear housing is stopped via the planetary gears, and the rotor rotates with respect to the gear housing, so that a braking force is applied to the rotation of the rotor via the viscous fluid, and the braking force to the movement of the rack body is applied. Granted.
また、ラック体が前記とは反対側に移動するときには、ギヤハウジングの回転に伴って遊星ギヤが収容部の他側に移動し、回転許容部に当接して回転を許容されるので、ロータの回転に連れまわるようにギヤハウジングが回転し、ロータの回転に対する制動力が解除され、ラック体の移動に対する制動力が解除される。 Further, when the rack body moves to the opposite side to the above, the planetary gear moves to the other side of the accommodating portion as the gear housing rotates, and abuts on the rotation permitting portion to allow rotation. The gear housing rotates so as to accompany the rotation, the braking force against the rotation of the rotor is released, and the braking force against the movement of the rack body is released.
そして、ギヤハウジングの回転規制や回転規制解除は、遊星ギヤが収容部内を移動することによってなされるので、切り替え動作を円滑に行うことができ、ラック体の移動方向の反転時における制動力応答性を良好にすることができる。 Since the rotation regulation and the rotation regulation release of the gear housing are performed by moving the planetary gear in the accommodating portion, the switching operation can be smoothly performed, and the braking force responsiveness when the moving direction of the rack body is reversed. Can be improved.

　以下、図面を参照して、本発明に係るダンパー装置の実施形態について説明する。図１～１１には、本発明に係るダンパー装置の一実施形態が示されている。 Hereinafter, embodiments of the damper device according to the present invention will be described with reference to the drawings. 1 to 11 show an embodiment of the damper device according to the present invention.
　図１，２に示すように、このダンパー装置１００は、回転ダンパー１１０と、該回転ダンパー１１０を回転可能に保持するケース１３０と、回転ダンパー１１０に対してスライド可能に装着され、回転ダンパー１１０に設けられたピニオンギヤ１２０に歯合するラックギヤ１７０（図６参照）を有するラック体１６０とを備えている。 As shown in FIGS. 1 and 2, the damper device 100 is slidably mounted on the rotary damper 110, the case 130 for holding the rotary damper 110 rotatably, and the rotary damper 110, and is attached to the rotary damper 110. It includes a rack body 160 having a rack gear 170 (see FIG. 6) that meshes with the provided pinion gear 120.
　図３，４，５を併せて参照すると、回転ダンパー１１０は、ロータ１１１と、このロータ１１１を粘性流体を介して囲み、ロータ１１１の回転に対して制動力を与えるギヤハウジング１１５とを有している。ギヤハウジング１１５は、内側にロータ１１１を収容する凹部１１７を有し、外周にギヤが形成された大径ギヤ１１６と、この大径ギヤ１１６の凹部１１７の開口部を封止するキャップ１１８とを有している。キャップ１１８の中央部には、ロータ１１１に設けられた支軸１１２が挿通される軸挿通孔１１９が形成されている。また、大径ギヤ１１６の下面には、後述するケース１３０の底壁１３１に設けられた円弧状リブ１３２が嵌合し、回転ダンパー１１０を回転可能に支持するための環状溝１２３が形成されている（図５参照）。 With reference to FIGS. 3, 4 and 5, the rotary damper 110 includes a rotor 111 and a gear housing 115 that surrounds the rotor 111 with a viscous fluid and applies a braking force to the rotation of the rotor 111. ing. The gear housing 115 has a recess 117 for accommodating the rotor 111 inside, and a large-diameter gear 116 having a gear formed on the outer periphery thereof and a cap 118 for sealing the opening of the recess 117 of the large-diameter gear 116. Have. A shaft insertion hole 119 through which the support shaft 112 provided in the rotor 111 is inserted is formed in the central portion of the cap 118. Further, on the lower surface of the large-diameter gear 116, an arcuate rib 132 provided on the bottom wall 131 of the case 130, which will be described later, is fitted, and an annular groove 123 for rotatably supporting the rotary damper 110 is formed. (See Fig. 5).
　ロータ１１１は、全体として円板状をなし、その片面の中央部から支軸１１２が突設され、支軸１１２は、シールリング１１３を介してキャップ１１８の軸挿通孔１１９に挿通され、ギヤハウジング１１５の外部に突出している。ピニオンギヤ１２０は、外周にギヤ部１２１を有し、中心部に軸孔１２２が形成されており、この軸孔１２２に前記支軸１１２が挿入固定されて、支軸１１２とピニオンギヤ１２０とが一体に回転するようになっている。 The rotor 111 has a disk shape as a whole, and a support shaft 112 projects from the center of one side of the rotor 111. The support shaft 112 is inserted into a shaft insertion hole 119 of a cap 118 via a seal ring 113, and a gear housing is provided. It protrudes to the outside of 115. The pinion gear 120 has a gear portion 121 on the outer periphery and a shaft hole 122 is formed in the central portion. The support shaft 112 is inserted and fixed in the shaft hole 122, and the support shaft 112 and the pinion gear 120 are integrally formed. It is designed to rotate.
　したがって、大径ギヤ１１６が回転規制された状態でピニオンギヤ１２０が回転すると、支軸１１２を介してロータ１１１がギヤハウジング１１５に対して相対回転するので、粘性流体を介してロータ１１１の回転に対して制動力が付与されるようになっている。 Therefore, when the pinion gear 120 rotates while the large-diameter gear 116 is restricted in rotation, the rotor 111 rotates relative to the gear housing 115 via the support shaft 112, so that the rotor 111 rotates with respect to the rotation of the rotor 111 via the viscous fluid. Braking force is applied.
　図１，２，４，５を併せて参照すると、ケース１３０は、底壁１３１と、この底壁１３１の両側から立設された一対の側壁１３４と、一対の側壁１３４の一方の端部どうしを連結するように、底壁１３１から立設された前壁１３９とを有しており、前壁１３９と反対側は、回転ダンパー１１０を挿入するための挿入開口部１３８をなしている。また、底壁１３１の内面には、円弧状リブ１３２が形成されており、回転ダンパー１１０の大径ギヤ１１６の底面に形成された環状溝１２３に、上記円弧状リブ１３２が嵌合して（図５参照）、大径ギヤ１１６を回転可能に支持するようになっている。 Referring to FIGS. 1, 2, 4 and 5, the case 130 has a bottom wall 131, a pair of side walls 134 erected from both sides of the bottom wall 131, and one end of the pair of side walls 134. It has a front wall 139 erected from the bottom wall 131 so as to connect the two, and the side opposite to the front wall 139 forms an insertion opening 138 for inserting the rotary damper 110. Further, an arc-shaped rib 132 is formed on the inner surface of the bottom wall 131, and the arc-shaped rib 132 is fitted into the annular groove 123 formed on the bottom surface of the large-diameter gear 116 of the rotary damper 110 ( (See FIG. 5), the large-diameter gear 116 is rotatably supported.
　また、底壁１３１の外面（下面）側には、ダンパー作用を与える部材に取付けるためのフック１３３が設けられている。例えばグローブボックスに適用される場合には、このフック１３３が車体側に設けられた本体部の側壁に取付けられ、後述するラック体１６０のブラケット１６５が、本体部に対して開閉可能に装着されるグローブボックスの側壁に連結されるようになっている。 Further, on the outer surface (lower surface) side of the bottom wall 131, a hook 133 for attaching to a member giving a damper action is provided. For example, when applied to a glove box, the hook 133 is attached to the side wall of the main body provided on the vehicle body side, and the bracket 165 of the rack body 160, which will be described later, is attached to the main body so as to be openable and closable. It is designed to be connected to the side wall of the glove box.
　一対の側壁１３４の上端縁には、互いに内側に向かって押えフランジ１３５が延出されており、この押えフランジ１３５が後述するラック体１６０の両側のガイドリブ１６３の上に覆い被さって、ラック体１６０をスライド可能に保持するようになっている。また、一対の押えフランジ１３５の向き合った対向する辺部には、それぞれスリットを介して弾性片１３６が形成され、この弾性片１３６の中間部には、後述するラック体１６０の側壁１６２に弾性的に当接する押圧凸部１３７が形成されている。 Presser flanges 135 extend inward from each other on the upper end edges of the pair of side walls 134, and the presser flanges 135 cover the guide ribs 163 on both sides of the rack body 160, which will be described later, to cover the rack body 160. Is designed to be slidable. In addition, elastic pieces 136 are formed on the facing side portions of the pair of holding flanges 135 via slits, and elastic pieces 162 are elastically formed on the side wall 162 of the rack body 160 described later in the intermediate portion of the elastic pieces 136. A pressing convex portion 137 that comes into contact with the surface is formed.
　また、図８，９を併せて参照すると、ケース１３０の一対の側壁１３４と前壁１３９との連結部分の内側には、後述する遊星ギヤ１５０を収容する収容部１４０がそれぞれ形成されている。収容部１４０は、遊星ギヤ１５０を大径ギヤ１１６の外周に沿って所定距離だけ移動可能に遊星ギヤ１５０を保持する形状をなしており、図８に示す中心線Ｌに対して線対称な形状をなして一対設けられている。収容部１４０の、遊星ギヤ１５０の移動方向の一方の端部（図８における中心線Ｌに近接した端部）には、遊星ギヤ１５０のギヤ部１５１が当接したとき、遊星ギヤ１５０の回転を規制する係合部１４１が設けられている。この実施形態の場合、係合部１４１は、遊星ギヤ１５０のギヤ部１５１に噛み込み可能な角部で構成されている。また、収容部１４０の、遊星ギヤ１５０の移動方向の他方の端部（図８における中心線Ｌから離れた端部）には、遊星ギヤ１５０が当接したとき、遊星ギヤ１５０の回転を許容する回転許容部１４２が設けられている。この実施形態の場合、回転許容部１４２は、平面的に見て円弧状をなす凹状湾曲面で構成されており、遊星ギヤ１５０はこの湾曲面に当接しながら回転が可能となっている。 Further, referring to FIGS. 8 and 9, each of the accommodating portions 140 for accommodating the planetary gear 150, which will be described later, is formed inside the connecting portion between the pair of side wall 134s of the case 130 and the front wall 139. The accommodating portion 140 has a shape that holds the planetary gear 150 so that the planetary gear 150 can be moved along the outer circumference of the large-diameter gear 116 by a predetermined distance, and has a shape that is line-symmetric with respect to the center line L shown in FIG. A pair is provided. The rotation of the planetary gear 150 when the gear portion 151 of the planetary gear 150 comes into contact with one end of the accommodating portion 140 in the moving direction of the planetary gear 150 (the end close to the center line L in FIG. 8). An engaging portion 141 is provided to regulate the speed. In the case of this embodiment, the engaging portion 141 is composed of a corner portion that can be engaged with the gear portion 151 of the planetary gear 150. Further, when the planetary gear 150 comes into contact with the other end of the accommodating portion 140 in the moving direction of the planetary gear 150 (the end away from the center line L in FIG. 8), the planetary gear 150 is allowed to rotate. A rotation permitting portion 142 is provided. In the case of this embodiment, the rotation allowance portion 142 is formed of a concave curved surface having an arc shape when viewed in a plane, and the planetary gear 150 can rotate while abutting on the curved surface.
　図６，７を併せて参照すると、ラック体１６０は、細長い板状をなす基板１６１と、この基板１６１の幅方向の両側に基板１６１の内面側（回転ダンパー１１０に向く方向）に向けて立設された一対の側壁１６２と、側壁１６２の突出方向の端部からそれぞれ外方に延出されたガイドリブ１６３とを有している。 With reference to FIGS. 6 and 7, the rack body 160 stands on the elongated plate-shaped substrate 161 and on both sides of the substrate 161 in the width direction toward the inner surface side of the substrate 161 (direction toward the rotary damper 110). It has a pair of side walls 162 provided and a guide rib 163 extending outward from each end of the side wall 162 in the projecting direction.
　図４に示すように、ラック体１６０は、ケース１３０に挿入されたとき、基板１６１の内面側（下面側）の幅方向中央部に支軸１１２の突出端面に形成された凸部１１４が当接し、ガイドリブ１６３の上面側に押えフランジ１３５が覆い被さって、ケース１３０の内側にスライド可能に保持されるようになっている。このとき、図７に示すように、押えフランジ１３５に設けられた弾性片１３６の押圧凸部１３７が、ラック体１６０の側壁１６２に弾性的に当接し、ラック体１６０はケース１３０内でガタ付きなく保持される。 As shown in FIG. 4, when the rack body 160 is inserted into the case 130, the convex portion 114 formed on the protruding end surface of the support shaft 112 hits the central portion in the width direction on the inner surface side (lower surface side) of the substrate 161. The pressing flange 135 covers the upper surface side of the guide rib 163 so as to be slidably held inside the case 130. At this time, as shown in FIG. 7, the pressing convex portion 137 of the elastic piece 136 provided on the holding flange 135 elastically contacts the side wall 162 of the rack body 160, and the rack body 160 rattles in the case 130. Is retained without.
　図６に示すように、一方の側壁１６２の内面側には長手方向に沿ってラックギヤ１７０が形成されており、このラックギヤ１７０が回転ダンパー１１０の支軸１１２に装着されたピニオンギヤ１２０と歯合するようになっている。したがって、ケース１３０に対してラック体１６０がスライド動作すると、ラックギヤ１７０に歯合するピニオンギヤ１２０が回転し、支軸１１２を介してロータ１１１が回転するようになっている。 As shown in FIG. 6, a rack gear 170 is formed along the longitudinal direction on the inner surface side of one side wall 162, and the rack gear 170 meshes with the pinion gear 120 mounted on the support shaft 112 of the rotary damper 110. It has become like. Therefore, when the rack body 160 slides with respect to the case 130, the pinion gear 120 meshing with the rack gear 170 rotates, and the rotor 111 rotates via the support shaft 112.
　ラック体１６０の一方の端部には、一対のブラケット１６５が平行に延出されており、各ブラケット１６５には取付孔１６６がそれぞれ形成されている。この取付孔１６６に、例えばグローブボックスの側壁に突設された取付軸が挿入されて、ラック体１６０の一端がグローブボックスなどの制動力を付与したい部品に取付けられるようになっている。 A pair of brackets 165 extend in parallel to one end of the rack body 160, and mounting holes 166 are formed in each bracket 165. For example, a mounting shaft projecting from the side wall of the glove box is inserted into the mounting hole 166 so that one end of the rack body 160 can be mounted on a component such as the glove box to which braking force is to be applied.
　また、ラック体１６０の一対のガイドリブ１６３の長手方向の一端部に近接した部分には、それぞれストッパ部１６４が突設されており、図７（ｂ）に示すように、ケース１３０に対してラック体１６０が引き出されるとき、ケース１３０の一対の側壁１３４の端部がストッパ部１６４に当接すると、それ以上の引き出しが規制されるようになっている。 Further, a stopper portion 164 is projected from each portion of the rack body 160 close to one end portion in the longitudinal direction of the pair of guide ribs 163, and as shown in FIG. 7B, the rack with respect to the case 130. When the body 160 is pulled out, if the ends of the pair of side walls 134 of the case 130 come into contact with the stopper portion 164, further pulling out is restricted.
　また、図５及び図８に示すように、ラック体１６０の下面が遊星ギヤ１５０の上端面の一部にオーバーラップするように配置されており、遊星ギヤ１５０はそれによってケース１３０からの抜け止めがなされるようになっている。このようにラック体１６０を用いた遊星ギヤ１５０の抜け止めができるので、簡素な構造にしてコンパクト化を図ることができる。 Further, as shown in FIGS. 5 and 8, the lower surface of the rack body 160 is arranged so as to overlap a part of the upper end surface of the planetary gear 150, whereby the planetary gear 150 is prevented from coming off from the case 130. Is to be done. Since the planetary gear 150 can be prevented from coming off by using the rack body 160 in this way, it is possible to make the structure simple and compact.
　次に、上記構成からなるダンパー装置１００の作用について説明する。 Next, the operation of the damper device 100 having the above configuration will be described.
　ダンパー装置１００は、制動力を与えたい、近接離反する一対の部品間に装着される。例えばグローブボックスの場合には、前述したように、車体側に設けられた本体部の側壁にケース１３０のフック１３３が連結され、本体部に対して開閉動作を行うグローブボックスの側壁にブラケット１６５が取付孔１６６を介して連結される。そして、グローブボックスを閉じた状態では、図７（ａ）に示すように、ブラケット１６５がケース１３０に近接した位置にあり、グローブボックスが引き出されるときには、ケース１３０に対してラック体１６０が引き出されてストッパ部１６４がケース１３０に当接したところで、それ以上の引き出しが規制されるようになっている。この実施形態では、グローブボックスを引き出すとき、すなわち、図７（ａ）から同図（ｂ）に至る過程において、回転ダンパー１１０による制動力が付与され、グローブボックスが急激に開かないようにするために、ダンパー装置１００が用いられている。 The damper device 100 is mounted between a pair of parts that are close to each other and want to apply a braking force. For example, in the case of a glove box, as described above, the hook 133 of the case 130 is connected to the side wall of the main body provided on the vehicle body side, and the bracket 165 is attached to the side wall of the glove box that opens and closes the main body. It is connected via the mounting hole 166. When the glove box is closed, the bracket 165 is located close to the case 130 as shown in FIG. 7A, and when the glove box is pulled out, the rack body 160 is pulled out with respect to the case 130. When the stopper portion 164 comes into contact with the case 130, further withdrawal is restricted. In this embodiment, when the glove box is pulled out, that is, in the process from FIG. 7 (a) to FIG. 7 (b), a braking force is applied by the rotary damper 110 to prevent the glove box from opening suddenly. The damper device 100 is used.
　図８に示すように、ケース１３０に対してラック体１６０がＡ方向に引き出されるとき、ラックギヤ１７０に歯合するピニオンギヤ１２０が図中の矢印Ｃで示す反時計回りの方向に回転する。すると、ピニオンギヤ１２０に支軸１１２を介して連設されたロータ１１１が回転し、粘性流体を介してロータ１１１に接触するギヤハウジング１１５も同方向に回転しようとする（図５参照）。その結果、大径ギヤ１１６が図８中の矢印Ｃで示す反時計回り方向に回転し、大径ギヤ１１６に歯合する遊星ギヤ１５０が収容部１４０内にて反時計回りの方向に移動する。すると、遊星ギヤ１５０のギヤ部１５１が収容部１４０の係合部１４１に係合し、遊星ギヤ１５０の回転が規制されるので、大径ギヤ１１６の回転が停止し、ギヤハウジング１１５内でロータ１１１のみが回転することになる。このため、粘性流体を介してロータ１１１の回転に対する制動力が付与され、ラック体１６０の矢印Ａ方向への移動に対する制動力として作用する。それによってグローブボックスが急激に開くことを抑制できる。 As shown in FIG. 8, when the rack body 160 is pulled out in the A direction with respect to the case 130, the pinion gear 120 meshing with the rack gear 170 rotates in the counterclockwise direction indicated by the arrow C in the drawing. Then, the rotor 111 serially connected to the pinion gear 120 via the support shaft 112 rotates, and the gear housing 115 that contacts the rotor 111 via the viscous fluid also tries to rotate in the same direction (see FIG. 5). As a result, the large-diameter gear 116 rotates in the counterclockwise direction indicated by the arrow C in FIG. 8, and the planetary gear 150 meshing with the large-diameter gear 116 moves in the counterclockwise direction in the accommodating portion 140. .. Then, the gear portion 151 of the planetary gear 150 engages with the engaging portion 141 of the accommodating portion 140, and the rotation of the planetary gear 150 is restricted, so that the rotation of the large-diameter gear 116 is stopped and the rotor is inside the gear housing 115. Only 111 will rotate. Therefore, a braking force for the rotation of the rotor 111 is applied via the viscous fluid, and acts as a braking force for the movement of the rack body 160 in the arrow A direction. As a result, the glove box can be prevented from opening suddenly.
　次に、図９に示すように、ケース１３０に対してラック体１６０がＢ方向に押し込まれるとき、ラックギヤ１７０に歯合するピニオンギヤ１２０が図中の矢印Ｄで示す時計回りの方向に回転する。すると、ピニオンギヤ１２０に支軸１１２を介して連設されたロータ１１１が回転し、粘性流体を介してロータ１１１に接触するギヤハウジング１１５も同方向に回転しようとする（図５参照）。その結果、大径ギヤ１１６が図９中の矢印Ｄで示す時計回り方向に回転し、大径ギヤ１１６に歯合する遊星ギヤ１５０が収容部１４０内にて時計回りの方向に移動する。すると、遊星ギヤ１５０のギヤ部１５１が収容部１４０の回転許容部１４２の内壁に当接し、遊星ギヤ１５０の回転が許容されるので、ロータ１１１と一緒に大径ギヤ１１６も回転し、ラック体１６０の移動に対する制動力が解除される。その結果、ラック体１６０はケース１３０に対して抵抗感が少なく押し込まれ、グローブボックスが閉じる動作を迅速に行わせることができる。 Next, as shown in FIG. 9, when the rack body 160 is pushed in the B direction with respect to the case 130, the pinion gear 120 meshing with the rack gear 170 rotates in the clockwise direction indicated by the arrow D in the drawing. Then, the rotor 111 serially connected to the pinion gear 120 via the support shaft 112 rotates, and the gear housing 115 that contacts the rotor 111 via the viscous fluid also tries to rotate in the same direction (see FIG. 5). As a result, the large-diameter gear 116 rotates in the clockwise direction indicated by the arrow D in FIG. 9, and the planetary gear 150 meshing with the large-diameter gear 116 moves in the clockwise direction in the accommodating portion 140. Then, the gear portion 151 of the planetary gear 150 comes into contact with the inner wall of the rotation allowable portion 142 of the accommodating portion 140, and the rotation of the planetary gear 150 is permitted. Therefore, the large diameter gear 116 also rotates together with the rotor 111, and the rack body The braking force for the movement of 160 is released. As a result, the rack body 160 is pushed into the case 130 with less resistance, and the glove box can be quickly closed.
　そして、このダンパー装置１００では、ラック体１６０の移動方向が反転するとき、大径ギヤ１１６よりも外径の小さい遊星ギヤ１５０が収容部１４０内を移動することによって制動力の切り替えがなされるので、切り替えに必要な移動距離を短くして、制動力切り替えの応答性を良好にすることができる。 Then, in this damper device 100, when the moving direction of the rack body 160 is reversed, the braking force is switched by the planetary gear 150 having an outer diameter smaller than that of the large diameter gear 116 moving in the accommodating portion 140. , The movement distance required for switching can be shortened, and the responsiveness of braking force switching can be improved.
　また、この実施形態では、図８に示すように、ケース１３０が中心線Ｌに対して線対称な形状に形成されていて、中心線Ｌに対して線対称な位置に一対の収容部１４０が形成されている。このため、遊星ギヤ１５０を挿入配置する収容部１４０を選択することによって、ラック体１６０の制動方向を変更することができる。 Further, in this embodiment, as shown in FIG. 8, the case 130 is formed in a shape line-symmetrical with respect to the center line L, and a pair of accommodating portions 140 are arranged at positions line-symmetrical with respect to the center line L. It is formed. Therefore, the braking direction of the rack body 160 can be changed by selecting the accommodating portion 140 in which the planetary gear 150 is inserted and arranged.
　すなわち、図１０に示すように、図８とは反対側の収容部１４０に遊星ギヤ１５０を配置すると、ラック体１６０が矢印Ａ方向に移動するとき、ピニオンギヤ１２０が矢印Ｃで示す反時計方向に回転し、遊星ギヤ１５０が収容部１４０の回転許容部１４２に当接して回転を許容されるので、制動力が付与しないようにすることができる。 That is, as shown in FIG. 10, when the planetary gear 150 is arranged in the accommodating portion 140 on the opposite side of FIG. 8, when the rack body 160 moves in the direction of arrow A, the pinion gear 120 moves in the counterclockwise direction indicated by arrow C. Since the planetary gear 150 rotates and the planetary gear 150 abuts on the rotation permitting portion 142 of the accommodating portion 140 to allow rotation, it is possible to prevent the braking force from being applied.
　また、図１１に示すように、図９とは反対側の収容部１４０に遊星ギヤ１５０を配置すると、ラック体１６０が矢印Ｂ方向に移動するとき、ピニオンギヤ１２０が矢印Ｄで示す時計回りの方向に回転し、遊星ギヤ１５０が収容部１４０の係合部１４１に係合して回転を規制され、大径ギヤ１１６の回転が規制されるので、ラック体１６０の移動に対して制動力を付与することができる。 Further, as shown in FIG. 11, when the planetary gear 150 is arranged in the accommodating portion 140 on the opposite side of FIG. 9, when the rack body 160 moves in the direction of arrow B, the pinion gear 120 moves in the clockwise direction indicated by arrow D. The planetary gear 150 engages with the engaging portion 141 of the accommodating portion 140 to regulate the rotation, and the rotation of the large diameter gear 116 is restricted, so that a braking force is applied to the movement of the rack body 160. can do.
　したがって、同じダンパー装置１００で、遊星ギヤ１５０の配置を変えるだけで、ケース１３０に対するラック体１６０の制動方向を適宜変更することが可能となる。 Therefore, with the same damper device 100, it is possible to appropriately change the braking direction of the rack body 160 with respect to the case 130 simply by changing the arrangement of the planetary gears 150.
　図１２、１３には、本発明の他の実施形態が示されている。なお、以下の実施形態の説明においては、図１～１１に示した実施形態と実質的に同じ部分には同符号を付してその説明を省略することにする。 12 and 13 show other embodiments of the present invention. In the following description of the embodiment, substantially the same parts as those of the embodiments shown in FIGS. 1 to 11 are designated by the same reference numerals and the description thereof will be omitted.
　このダンパー装置１００ａは、遊星ギヤ１５０のケース１３０内からの抜け止め構造が前記実施形態と異なっている。すなわち、回転ダンパー１１０のギヤハウジング１１５を構成する大径ギヤ１１６とキャップ１１８のうち、キャップ１１８の外径が大きくされて大径ギヤ１１６の外径より外方に突出している。一方、遊星ギヤ１５０の軸方向長さが前記実施形態よりも短くされて、前記突出したキャップ１１８の外周縁部が、遊星ギヤ１５０の軸方向端面の少なくとも一部に当接可能に配置され、それによって遊星ギヤ１５０の抜け止めがなされている。 This damper device 100a is different from the above-described embodiment in the structure for preventing the planetary gear 150 from coming out of the case 130. That is, of the large diameter gear 116 and the cap 118 constituting the gear housing 115 of the rotary damper 110, the outer diameter of the cap 118 is increased and protrudes outward from the outer diameter of the large diameter gear 116. On the other hand, the axial length of the planetary gear 150 is shorter than that of the embodiment, and the outer peripheral edge of the protruding cap 118 is arranged so as to be in contact with at least a part of the axial end surface of the planetary gear 150. As a result, the planetary gear 150 is prevented from coming off.
　上記実施形態によれば、ギヤハウジング１１５のキャップ１１８によって遊星ギヤ１５０の抜け止めがなされるので、ケース１３０の底壁１３１に対して低い位置で遊星ギヤ１５０を抜け止めでき、遊星ギヤ１５０が傾きにくくすることができる。 According to the above embodiment, since the cap 118 of the gear housing 115 prevents the planetary gear 150 from coming off, the planetary gear 150 can be prevented from coming off at a position lower than the bottom wall 131 of the case 130, and the planetary gear 150 is tilted. It can be made difficult.
　図１４～１６には、本発明の更に他の実施形態が示されている。このダンパー装置１００ｂは、遊星ギヤ１５０ａと大径ギヤ１１６ａの形状が前記実施形態と異なっている。 14 to 16 show still other embodiments of the present invention. The shape of the planetary gear 150a and the large-diameter gear 116a of the damper device 100b is different from that of the embodiment.
　すなわち、この実施形態では、遊星ギヤ１５０ａのギヤ部１５１がハスバギヤをなし、大径ギヤ１１６ａも遊星ギヤ１５０ａに歯合可能なハスバギヤをなしている。それぞれのハスバギヤの傾き方向は、特に限定されないが、遊星ギヤ１５０ａが収容部１４０の回転許容部１４２に移動し、大径ギヤ１１６ａに歯合して回転する際に、遊星ギヤ１５０ａをケース１３０の底壁１３１に押し付ける力が作用するように、ハスバギヤの傾き方向が設定されていることが好ましい。それによって遊星ギヤ１５０ａをケース１３０の底壁１３１に押し付けて、遊星ギヤ１５０ａのガタ付きを抑制することができる。 That is, in this embodiment, the gear portion 151 of the planetary gear 150a forms a hasba gear, and the large diameter gear 116a also forms a hasba gear that can be meshed with the planetary gear 150a. The tilting direction of each of the hasba gears is not particularly limited, but when the planetary gear 150a moves to the rotation allowable portion 142 of the accommodating portion 140 and rotates in mesh with the large diameter gear 116a, the planetary gear 150a is moved to the case 130. It is preferable that the tilting direction of the hasba gear is set so that the force pressing against the bottom wall 131 acts. As a result, the planetary gear 150a can be pressed against the bottom wall 131 of the case 130 to suppress rattling of the planetary gear 150a.
　図１７～１９には、本発明の更に他の実施形態が示されている。このダンパー装置１００ｃは、遊星ギヤ１５０ｂの形状が前記実施形態と異なっている。 FIGS. 17-19 show still other embodiments of the present invention. The shape of the planetary gear 150b of the damper device 100c is different from that of the embodiment.
　すなわち、この実施形態の遊星ギヤ１５０ｂは、ギヤ部１５１の軸方向端面に隣接して、ギヤ部１５１の外径と同じか、それより大きい外径の円板部１５２が形成されている。このため、図１９に示すように、遊星ギヤ１５０ｂが収容部１４０の回転許容部１４２に当接して回転するとき、円板部１５２が回転許容部１４２の内周に当接して滑らかな回転がなされ、異音の発生を抑制することができる。なお、収容部１４０の係合部１４１は、前記実施形態よりも低くされ、円板部１５２は、係合部１４１には当接しないようになっている。 That is, in the planetary gear 150b of this embodiment, a disk portion 152 having an outer diameter equal to or larger than the outer diameter of the gear portion 151 is formed adjacent to the axial end surface of the gear portion 151. Therefore, as shown in FIG. 19, when the planetary gear 150b abuts on the rotation allowance portion 142 of the accommodating portion 140 and rotates, the disc portion 152 abuts on the inner circumference of the rotation allowance portion 142 and smooth rotation occurs. This is done, and the generation of abnormal noise can be suppressed. The engaging portion 141 of the accommodating portion 140 is lowered as compared with the above-described embodiment, and the disc portion 152 does not come into contact with the engaging portion 141.
　図２０、２１には、本発明の更に他の実施形態が示されている。このダンパー装置１００ｄは、遊星ギヤ１５０ｃの形状及び収容部１４０の底面の形状が前記実施形態と異なっている。 20 and 21 show still other embodiments of the present invention. In this damper device 100d, the shape of the planetary gear 150c and the shape of the bottom surface of the accommodating portion 140 are different from those of the above-described embodiment.
　すなわち、このダンパー装置１００ｄの遊星ギヤ１５０ｃは、図１７～１９の実施形態と同様に、ギヤ部１５１の軸方向端面（図中上端面）に隣接して、ギヤ部１５１の外径と同じか、それより大きい外径の円板部１５２が形成されていると共に、円板部１５２と反対側の端面の中心部に、ギヤ部１５１よりも小さい外径で下方に突出する円柱部１５３が形成されている。 That is, is the planetary gear 150c of the damper device 100d adjacent to the axial end surface (upper end surface in the drawing) of the gear portion 151 and the same as the outer diameter of the gear portion 151, as in the embodiment of FIGS. 17 to 19. A disk portion 152 having an outer diameter larger than that is formed, and a columnar portion 153 projecting downward with an outer diameter smaller than that of the gear portion 151 is formed at the center of the end surface opposite to the disk portion 152. Has been done.
　また、ケース１３０の収容部１４０の底面には、前記円柱部１５３が挿入される支持溝１４３が設けられている。この支持溝１４３は、大径ギヤ１１６の外周に沿って遊星ギヤ１５０ｃが大径ギヤ１１６に適切に噛み合う距離をおいて移動できる形状をなしている。また、支持溝１４３の回転許容部１４２に近接する一方の端部は、円柱部１５３の外周が適合する円弧状をなし、遊星ギヤ１５０が回転許容部１４２に移動したとき、円柱部１５３を支持して遊星ギヤ１５０の回転が円滑に行われるようにしている。このように、この実施形態では、遊星ギヤ１５０ｃの移動が、円柱部１５３が支持溝１４３にガイドされながらなされるので、遊星ギヤ１５０ｃをガタ付きなく移動させることができ、遊星ギヤ１５０ｃの回転や移動による異音の発生をより効果的に抑制することができる。 Further, a support groove 143 into which the columnar portion 153 is inserted is provided on the bottom surface of the accommodating portion 140 of the case 130. The support groove 143 has a shape that allows the planetary gear 150c to move along the outer circumference of the large-diameter gear 116 at a distance that allows the planetary gear 150c to appropriately mesh with the large-diameter gear 116. Further, one end of the support groove 143 close to the rotation allowable portion 142 has an arc shape to which the outer circumference of the cylindrical portion 153 matches, and supports the cylindrical portion 153 when the planetary gear 150 moves to the rotation allowable portion 142. Therefore, the planetary gear 150 is smoothly rotated. As described above, in this embodiment, the planetary gear 150c is moved while the cylindrical portion 153 is guided by the support groove 143, so that the planetary gear 150c can be moved without rattling, and the planetary gear 150c can be rotated. It is possible to more effectively suppress the generation of abnormal noise due to movement.
　図２２には、本発明の更に他の実施形態が示されている。このダンパー装置１００ｅは、大径ギヤ１１６の形状が前記実施形態と異なっている。すなわち、この実施形態では、大径ギヤ１１６の上縁部１１６ａがキャップ１１８の外周を囲むようにフランジ状に延出され、上記上縁部１１６ａの下面が遊星ギヤ１５０の上端面の一部を覆うように配置されて、遊星ギヤ１５０のケース１３０内からの抜け止め構造をなしている。 FIG. 22 shows yet another embodiment of the present invention. The shape of the large-diameter gear 116 of the damper device 100e is different from that of the embodiment. That is, in this embodiment, the upper edge portion 116a of the large-diameter gear 116 extends in a flange shape so as to surround the outer circumference of the cap 118, and the lower surface of the upper edge portion 116a covers a part of the upper end surface of the planetary gear 150. It is arranged so as to cover it, and has a structure for preventing the planetary gear 150 from coming out of the case 130.
　上記実施形態によれば、ギヤハウジング１１５の大径ギヤ１１６の上縁部１１６ａによって遊星ギヤ１５０の抜け止めがなされるので、ケース１３０の底壁１３１に対して低い位置で遊星ギヤ１５０を抜け止めでき、遊星ギヤ１５０が傾きにくくすることができる。 According to the above embodiment, the planetary gear 150 is prevented from coming off by the upper edge 116a of the large diameter gear 116 of the gear housing 115, so that the planetary gear 150 is prevented from coming off at a position lower than the bottom wall 131 of the case 130. The planetary gear 150 can be made difficult to tilt.
