Description

この発明は、車両のドア開閉部等に用いられ、閉操作の際の衝撃を緩衝する緩衝体に関するものである。   The present invention relates to a shock absorber that is used in a door opening / closing portion of a vehicle and cushions an impact during a closing operation.

車両のドア開閉部には、ドアとドア開口部のいずれか一方に緩衝体が取り付けられ、ドア閉時に緩衝体が他方の部材に当接するようになっている。
この緩衝体は、一方の部材の取付孔に固定される固定部と、ドアを閉操作したときに他方の部材に当接する衝撃緩衝部と、を備えている。固定部としては、取付作業性を考慮して略円柱状の軸部の外周に螺旋溝を形成し、この螺旋溝を取付孔の孔縁にねじ込み状態で係止させるものが案出されている（例えば、特許文献１参照）。
特開２００６−９６１７２号公報 A shock absorber is attached to one of the door and the door opening in the door opening / closing part of the vehicle, and the shock absorber comes into contact with the other member when the door is closed.
The shock absorber includes a fixed portion that is fixed to the mounting hole of one member, and an impact buffer portion that contacts the other member when the door is closed. In consideration of mounting workability, a fixing portion has been devised in which a spiral groove is formed on the outer periphery of a substantially cylindrical shaft portion, and the spiral groove is locked to a hole edge of the mounting hole in a screwed state. (For example, refer to Patent Document 1).
JP 2006-96172 A

しかし、この従来の緩衝体は、被取付部材に対する取付作業を容易にするために取付孔をある程度大きく形成する必要があるが、取付孔が大きくなると、取付状態において固定部の周囲に隙間ができ易くなる。そして、固定部の周囲に隙間ができると、その隙間を通して排気ガス等の外気が進入し易くなる。
また、隙間を小さくするために取付孔の成形精度を高めると、成形作業が難しくなり、製造コストの高騰をことが懸念される。 However, in this conventional shock absorber, it is necessary to make the mounting hole large to some extent in order to facilitate the mounting work to the mounted member. However, when the mounting hole becomes large, a gap is formed around the fixed portion in the mounting state. It becomes easy. When a gap is formed around the fixed portion, outside air such as exhaust gas can easily enter through the gap.
Moreover, if the molding accuracy of the mounting hole is increased in order to reduce the gap, the molding operation becomes difficult and there is a concern that the manufacturing cost will rise.

そこで、この発明は、製造コストの高騰を招くことなく、簡単な構成によって隙間からの外気の進入を確実に防止することのできる緩衝体を提供しようとするものである。   Therefore, the present invention is intended to provide a shock absorber that can reliably prevent the entry of outside air from a gap with a simple configuration without causing an increase in manufacturing cost.

上記の課題を解決する請求項１に記載の発明は、固定部材と開閉部材のうちの一方の部材に取り付けられ、前記開閉部材の閉操作時に他方の部材に当接して衝撃を緩衝する緩衝体（例えば、後述の実施形態における緩衝体１１）であって、前記一方の部材に形成された取付孔（例えば、後述の実施形態における取付孔１０）に固定される固定部（例えば、後述の実施形態における固定部１２）と、閉操作時に前記他方の部材に当接する衝撃緩衝部（例えば、後述の実施形態における衝撃緩衝部１４）と、を備え、前記固定部には、略円柱状の軸部の外周面に形成され、前記取付孔の孔縁にねじ込み状態で係止される螺旋溝（例えば、後述の実施形態における螺旋溝１９）と、前記軸部の外周面の残余の部分に形成された螺旋周壁（例えば、後述の実施形態における螺旋周壁２２）と、前記螺旋周壁の幅方向の一部から径方向外側に突出するシール突条（例えば、後述の実施形態におけるシール突条２３）と、が設けられていることを特徴とする。
緩衝体を一方の部材に取り付ける場合には、固定部の螺旋溝に取付孔の孔縁を沿わせるようにして固定部を取付孔に対してねじ込む。これにより、取付孔の孔縁に螺旋溝が係止されるとともに、螺旋周壁から径方向外側に突出するシール突条が取付孔を覆うようになる。また、シール突条は螺旋周壁の幅方向の全域からではなく一部からのみ突出しているため、軸部のねじ込みの際のシール突条による抵抗は低減される。 The invention according to claim 1, which solves the above problem, is a shock absorber that is attached to one member of a fixing member and an opening / closing member, and abuts against the other member during operation of closing the opening / closing member to cushion an impact (For example, a buffer body 11 in an embodiment described later), and a fixing portion (for example, an implementation described later) fixed to an attachment hole (for example, an attachment hole 10 in an embodiment described later) formed in the one member. A fixed portion 12) in the form, and an impact buffering portion (for example, an impact buffering portion 14 in an embodiment described later) that contacts the other member during the closing operation, and the fixed portion has a substantially cylindrical shaft. Formed on the outer peripheral surface of the portion, and formed in the remaining portion of the outer peripheral surface of the shaft portion, and a spiral groove (for example, a spiral groove 19 in an embodiment described later) that is locked to the hole edge of the mounting hole in a screwed state. Spiral wall (for example, after And a seal protrusion (for example, a seal protrusion 23 in an embodiment described later) protruding outward in the radial direction from a part of the spiral peripheral wall in the width direction. It is characterized by.
When the buffer body is attached to one member, the fixing portion is screwed into the attachment hole so that the edge of the attachment hole is along the spiral groove of the fixing portion. As a result, the spiral groove is locked to the hole edge of the attachment hole, and the seal protrusion that protrudes radially outward from the spiral peripheral wall covers the attachment hole. Moreover, since the seal protrusion protrudes not only from the entire region in the width direction of the spiral peripheral wall but from only a part thereof, the resistance due to the seal protrusion when the shaft portion is screwed is reduced.

請求項２に記載の発明は、請求項１に記載の緩衝体において、前記螺旋周壁の幅方向の端部には、前記螺旋溝に隣接する略直角なエッジ部（例えば、後述の実施形態におけるエッジ部２４）が設けられていることを特徴とする。
これにより、螺旋溝の径方向外側の端部にエッジ部が位置されるようになり、エッジ部分が取付孔の孔縁に安定的に支持されるようになる。 According to a second aspect of the present invention, in the shock absorber according to the first aspect, an edge portion (for example, in an embodiment to be described later) adjacent to the spiral groove is disposed at an end in the width direction of the spiral peripheral wall. An edge portion 24) is provided.
Thereby, an edge part comes to be located in the edge part of the radial direction outer side of a spiral groove, and an edge part comes to be stably supported by the hole edge of an attachment hole.

請求項３に記載の発明は、請求項１または２に記載の緩衝体において、前記シール突条は、径方向外方に向かって先細りとなるテーパ状の断面形状とされていることを特徴とする。
これにより、取付孔に対する固定部のねじ込みの際のシール突条による抵抗はより低減されるようになる。 According to a third aspect of the present invention, in the shock absorber according to the first or second aspect, the seal protrusion has a tapered cross-sectional shape that tapers outward in the radial direction. To do.
Thereby, the resistance by the seal protrusion at the time of screwing of the fixing | fixed part with respect to an attachment hole comes to be reduced more.

請求項４に記載の発明は、請求項１〜３のいずれか１項に記載の緩衝体において、前記螺旋溝の底面には、溝方向に沿って円弧状に***する締め込み規制用のストッパ突起（例えば、後述の実施形態におけるストッパ突起２１）が形成されていることを特徴とする。
これにより、固定部を取付孔にねじ込む際に、取付孔の内周面が螺旋溝内のストッパ突起に乗り上げると、軸部の締め込みが規制されるようになる。このとき、ストッパ突起が溝方向に沿って円弧状に***しているため、軸部の回転停止位置は微調整することが可能になる。 According to a fourth aspect of the present invention, in the shock absorber according to any one of the first to third aspects, a tightening restricting stopper that protrudes in an arc shape along the groove direction on the bottom surface of the spiral groove. A protrusion (for example, a stopper protrusion 21 in an embodiment described later) is formed.
As a result, when the fixing portion is screwed into the attachment hole, the tightening of the shaft portion is restricted when the inner peripheral surface of the attachment hole rides on the stopper protrusion in the spiral groove. At this time, since the stopper protrusion is raised in an arc shape along the groove direction, the rotation stop position of the shaft portion can be finely adjusted.

請求項５に記載の発明は、請求項１〜４のいずれか１項に記載の緩衝体において、前記シール突条は、前記螺旋周壁と別体部品によって構成されていることを特徴とする。   According to a fifth aspect of the present invention, in the shock absorber according to any one of the first to fourth aspects, the seal protrusion is constituted by a separate part from the spiral peripheral wall.

請求項１に記載の発明によれば、螺旋周壁に幅方向の一部から径方向外側に突出するシール突条が設けられているため、シール突条が取付孔を覆い、軸部と取付孔の間の隙間をより小さくすることができる。したがって、簡単な構造でありながら、隙間からの外気の進入を低減することができる。
また、この発明の場合、シール突条が螺旋周壁の幅方向の全域からではなく一部から径方向外側に突出しているため、固定部のねじ込みの際の抵抗を低減し、取付作業性の向上を図ることができるという利点もある。 According to the first aspect of the present invention, since the seal protrusion that protrudes radially outward from a part in the width direction is provided on the spiral peripheral wall, the seal protrusion covers the attachment hole, and the shaft portion and the attachment hole. The gap between the two can be made smaller. Therefore, it is possible to reduce the entry of outside air from the gap while having a simple structure.
Further, in the case of the present invention, since the seal protrusion protrudes radially outward from a part rather than from the entire width direction of the spiral peripheral wall, the resistance at the time of screwing the fixing portion is reduced and the mounting workability is improved. There is also an advantage that can be achieved.

請求項２に記載の発明によれば、螺旋溝の径方向外側の端部に略直角なエッジ部が位置されるようになるため、固定部をエッジ部によって取付孔の孔縁に安定的に支持させ、取付状態での安定性を高めることができる。   According to the second aspect of the invention, since the edge portion that is substantially perpendicular to the radially outer end of the spiral groove is positioned, the fixing portion is stably attached to the edge of the mounting hole by the edge portion. It can be supported and the stability in an attached state can be improved.

請求項３に記載の発明によれば、シール突条が径方向外側に向かって先細りとなるテーパ状の断面形状とされているため、固定部のねじ込みの際の抵抗をより低減し、取付作業性のさらなる向上を図ることができる。   According to the third aspect of the present invention, since the seal protrusion has a tapered cross-sectional shape that tapers radially outward, the resistance when the fixing portion is screwed is further reduced, and the mounting work Further improvement in performance can be achieved.

請求項４に記載の発明によれば、螺旋溝内で円弧状に***するストッパ突起によって固定部の回転停止位置を微調整することができるため、この微調整によって固定部と取付孔の間の隙間をより小さくし、隙間からの外気の進入をより低減することができる。   According to the fourth aspect of the present invention, since the rotation stop position of the fixing portion can be finely adjusted by the stopper protrusion protruding in an arc shape in the spiral groove, the fine adjustment between the fixing portion and the mounting hole can be performed. The gap can be made smaller, and the entry of outside air from the gap can be further reduced.

請求項５に記載の発明によれば、シール突条を螺旋周壁と別体部品によって構成したため、シール突条を備えない既存の緩衝体を流用して容易に製造することができる。   According to the fifth aspect of the present invention, since the seal protrusion is configured by a separate part from the spiral peripheral wall, the existing buffer body that does not include the seal protrusion can be used easily and manufactured.

以下、この発明の一実施形態を図面に基づいて説明する。なお、以下の説明においては、特別に断らない限り、「上」「下」については車体に対しての上下を意味するものとする。
図１は、ハッチバックタイプの車両１の後部を示すものである。
同図に示すように、この車両１は、車体後部面に開口部２が設けられ、その開口部２に後部ドア３が開閉可能に設けられている。後部ドア３は、上端側が開口部２の上縁に跳ね上げ開閉可能に支持されている。そして、この後部ドア３は、閉状態において、車体のルーフ４から後方側に向かって下方傾斜する傾斜面と、傾斜面の後端部から下方に屈曲する垂立面とを備え、傾斜面にリヤガラス５が配置されるとともに、垂立面の上半部にエキストラウィンドウガラス６が配置されている。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, unless otherwise specified, “upper” and “lower” mean up and down relative to the vehicle body.
FIG. 1 shows a rear portion of a hatchback type vehicle 1.
As shown in the figure, the vehicle 1 is provided with an opening 2 in the rear surface of the vehicle body, and a rear door 3 is provided in the opening 2 so as to be openable and closable. The rear door 3 is supported so that the upper end side can be flipped up and opened at the upper edge of the opening 2. In the closed state, the rear door 3 includes an inclined surface that is inclined downward from the roof 4 of the vehicle body toward the rear side, and a vertical surface that is bent downward from the rear end portion of the inclined surface. A rear glass 5 is disposed, and an extra window glass 6 is disposed in the upper half of the vertical surface.

図２は、図１のＡ−Ａ断面に対応する断面図であり、同図中７は、車体の開口部２から車内側下方に延設されたガーターパネルであり、８は、後部ドア３の下面側に取り付けられたフレームパネルである。フレームパネル８の底壁９には略円形の取付孔１０が形成され、この取付孔１０に緩衝体１１が取り付けられている。緩衝体１１は、全体がゴムや軟質樹脂等のゴム状弾性体によって形成され、図３〜図５にも示すように、取付孔１０に固定される固定部１２と、後部ドア３の閉操作時に、下端がガーターパネル７の底壁１３の上面に当接する衝撃緩衝部１４と、を備えている。   2 is a cross-sectional view corresponding to the AA cross section of FIG. 1, in which 7 is a garter panel extending downward from the vehicle body opening 2 and 8 is a rear door 3. It is the frame panel attached to the lower surface side. A substantially circular mounting hole 10 is formed in the bottom wall 9 of the frame panel 8, and a buffer body 11 is mounted in the mounting hole 10. The entire buffer body 11 is formed of a rubber-like elastic body such as rubber or soft resin. As shown in FIGS. 3 to 5, the fixing portion 12 fixed to the mounting hole 10 and the rear door 3 are closed. Sometimes, an impact buffering portion 14 whose lower end is in contact with the upper surface of the bottom wall 13 of the garter panel 7 is provided.

緩衝体１１は、全体が略円柱状に形成され、軸方向の一端側に固定部１２が設けられ、他端側に衝撃緩衝部１４が設けられている。
衝撃緩衝部１４は、軸方向に充分な長さを持つ緩衝部本体１５の先端面（図２，図３中の下面）に窪み部１６が設けられ、その窪み部１６内に円筒壁１７が突設されている。この円筒壁１７は、緩衝部本体１５の平坦な先端面から前方に所定量突出し、後部ドア３の閉操作時に最初にガーターパネル７の底壁１３に当接するようになっている。つまり、衝撃緩衝部１４は、当接初期の衝撃を弾発力の小さい円筒壁１７によって吸収し、その後の大きな入力荷重を緩衝部本体１５全体で吸収する。また、緩衝部本体１５の外周面には、軸方向に沿って延出する複数の把持突起１８が形成されている。この把持突起１８は、作業者が緩衝体１１を取付孔１０に取付ける際の滑り止めとして用いられる。 The entire buffer body 11 is formed in a substantially cylindrical shape, a fixed portion 12 is provided on one end side in the axial direction, and an impact buffer portion 14 is provided on the other end side.
The shock absorbing portion 14 is provided with a hollow portion 16 on the front end surface (the lower surface in FIGS. 2 and 3) of the shock absorber main body 15 having a sufficient length in the axial direction, and a cylindrical wall 17 is provided in the hollow portion 16. Projected. The cylindrical wall 17 projects forward by a predetermined amount from the flat front end surface of the buffer portion main body 15, and first comes into contact with the bottom wall 13 of the garter panel 7 when the rear door 3 is closed. In other words, the shock absorbing portion 14 absorbs the impact at the initial stage of contact by the cylindrical wall 17 having a small elastic force, and then absorbs a large input load by the entire buffer portion main body 15. A plurality of gripping protrusions 18 extending in the axial direction are formed on the outer peripheral surface of the buffer portion main body 15. The gripping protrusion 18 is used as a slip stopper when an operator attaches the shock absorber 11 to the attachment hole 10.

一方、固定部１２は、緩衝部本体１５から連続する軸部の外周面に設定幅の螺旋溝１９が設けられるとともに、衝撃緩衝部１４と逆側の端部に截頭円錐状のガイド凸部２０が設けられている。螺旋溝１９は、取付孔１０の孔縁にねじ込み状態で係止される部分であり、図６にも示すように、延出方向のほぼ全域が断面略矩形状に形成されるとともに、ガイド凸部２０側の端部が解放されている。また、螺旋溝１９の衝撃緩衝部１４寄りの設定位置の底面には、図７，図８に示すように、溝の延出方向に沿って円弧状に***するストッパ突起２１が形成されている。このストッパ突起２１は、螺旋溝１９が取付孔１０の孔縁にねじ込まれた際に、取付孔１０の内周面が乗り上げることによって締め込みを規制する。   On the other hand, the fixed portion 12 is provided with a spiral groove 19 having a set width on the outer peripheral surface of the shaft portion continuous from the buffer portion main body 15, and a frustoconical guide convex portion at the end opposite to the impact buffer portion 14. 20 is provided. The spiral groove 19 is a portion that is locked to the hole edge of the mounting hole 10 in a screwed state. As shown in FIG. 6, almost the entire region in the extending direction is formed in a substantially rectangular cross section, and the guide protrusion The end on the part 20 side is released. Further, as shown in FIGS. 7 and 8, a stopper protrusion 21 is formed on the bottom surface of the spiral groove 19 near the impact buffering portion 14 so as to protrude in an arc shape along the extending direction of the groove. . The stopper protrusion 21 restricts tightening by the inner peripheral surface of the mounting hole 10 riding on when the spiral groove 19 is screwed into the hole edge of the mounting hole 10.

また、固定部１２は、軸部の外周面に螺旋溝１９を形成した結果、軸部の外周面の残余の部分には設定幅の螺旋周壁２２が形成されている。そして、この螺旋周壁２２の幅方向の中央領域には、径方向外側に向かって突出する山形状（先細りテーパー状）の断面形状のシール突条２３が一体に形成されている。このシール突条２３は螺旋周壁２２の延出方向に沿って螺旋状に設けられている。また、螺旋周壁２２の幅方向の両端部には、シール突条２３が形成されておらず、螺旋溝２２に隣接する略直角なエッジ部２４が設けられている。   In addition, as a result of forming the spiral groove 19 on the outer peripheral surface of the shaft portion, the fixed portion 12 has a spiral peripheral wall 22 having a set width formed on the remaining portion of the outer peripheral surface of the shaft portion. In the central region in the width direction of the spiral peripheral wall 22, a seal protrusion 23 having a cross-sectional shape with a mountain shape (tapered taper shape) protruding outward in the radial direction is integrally formed. The seal protrusion 23 is provided in a spiral shape along the extending direction of the spiral peripheral wall 22. In addition, seal ridges 23 are not formed at both ends in the width direction of the spiral peripheral wall 22, and substantially perpendicular edge portions 24 adjacent to the spiral groove 22 are provided.

この緩衝体１１を実際に後部ドア３のフレームパネル８に取付ける場合には、作業者が衝撃緩衝部１４を把持してフレームパネル８の取付孔１０にガイド凸部２０を挿入し、緩衝体１１全体を所定の方向に回転させる。これにより、緩衝体１１の螺旋溝１９は取付孔１０にねじ込まれる。この緩衝体１１のねじ込みは、取付孔１０の内周面が螺旋溝１９内のストッパ突起２１に乗り上げて、緩衝体１１の回転が規制されるまで行われる。   When the shock absorber 11 is actually attached to the frame panel 8 of the rear door 3, the operator holds the shock absorber 14 and inserts the guide protrusion 20 into the attachment hole 10 of the frame panel 8. The whole is rotated in a predetermined direction. Thereby, the spiral groove 19 of the buffer 11 is screwed into the mounting hole 10. The buffer body 11 is screwed in until the inner peripheral surface of the mounting hole 10 rides on the stopper protrusion 21 in the spiral groove 19 and the rotation of the buffer body 11 is restricted.

こうしてフレームパネル８に取り付けられた緩衝体１１は螺旋溝１９の下面と上面が取付孔１０の上下の孔縁に係止され、その状態において、シール突条２３が取付孔１０の上部側の孔縁から下部側の孔縁にかけてほぼ連続的に覆うようになる。したがって、この緩衝体１１を用いた場合には、固定部１２と取付孔１０の間の隙間がシール突条２３によってほぼ閉塞され、取付孔１０の隙間を通して車内に外気が進入するを防止される。
特に、この緩衝体１１は、断面テーパ状のシール突条２３が取付孔１０の孔縁に当接した場合にも厚み方向に柔軟に撓み変形するため、フレームパネル８の底壁９（取付孔１０の周縁部）が緩やかに湾曲している場合には、隙間の発生を効果的に防止することができる。 In this way, the shock absorber 11 attached to the frame panel 8 has the lower surface and the upper surface of the spiral groove 19 engaged with the upper and lower hole edges of the attachment hole 10, and in this state, the seal protrusion 23 is the hole on the upper side of the attachment hole 10. It covers almost continuously from the edge to the hole edge on the lower side. Therefore, when this shock absorber 11 is used, the gap between the fixed portion 12 and the mounting hole 10 is substantially blocked by the seal protrusion 23, thereby preventing outside air from entering the vehicle through the gap of the mounting hole 10. .
In particular, since the shock absorber 11 is flexibly deformed in the thickness direction even when the seal protrusion 23 having a tapered cross section comes into contact with the hole edge of the attachment hole 10, the shock absorber 11 is flexibly deformed in the thickness direction. When the peripheral edge 10 is gently curved, the generation of a gap can be effectively prevented.

また、この緩衝体１１においては、シール突条２３が螺旋周壁２２の幅方向の全域ではなく一部からのみ突出しているため、固定部１２のねじ込みの際の抵抗を低減できるという利点がある。そして、この実施形態の緩衝体１１の場合、シール突条２３が径方向外側に向かって先細りテーパ状の断面形状となっているため、ねじ込み時における抵抗をより低減するうえで有利となっている。したがって、この緩衝体１１においては、取付作業性が低下することもない。   Moreover, in this buffer body 11, since the seal protrusion 23 protrudes only from one part instead of the whole area | region of the width direction of the spiral surrounding wall 22, there exists an advantage that the resistance at the time of screwing of the fixing | fixed part 12 can be reduced. And in the case of the buffer body 11 of this embodiment, since the seal protrusion 23 has a taper-shaped cross-section tapering outward in the radial direction, it is advantageous for further reducing the resistance during screwing. . Therefore, in this buffer 11, attachment workability | operativity does not fall.

さらに、この実施形態の緩衝体１１は、螺旋周壁２２と螺旋溝１９の間に略直角なエッジ部２４が確保されているため、取付孔１０に取り付けた状態において、エッジ部２４によって取付孔１０の孔縁を安定的に支持することができる。したがって、この構造の採用により、緩衝体１１の取付状態での安定性を高めることができる。   Furthermore, since the shock absorber 11 of this embodiment has a substantially perpendicular edge portion 24 between the spiral peripheral wall 22 and the spiral groove 19, the attachment hole 10 is attached by the edge portion 24 in a state of being attached to the attachment hole 10. Can be stably supported. Therefore, by adopting this structure, the stability of the shock absorber 11 in the attached state can be enhanced.

また、この実施形態の緩衝体１１においては、締め込み規制用のストッパ突起２１が螺旋溝１９内に溝方向に沿って略円弧状に***するように形成されているため、回転規制状態においても、緩衝体１１の回転位置を比較的容易に微調整することができる。したがって、取付孔１０に対する固定部１２の偏心によってできる部分的な隙間を、この回転位置の微調整によって閉塞することができる。したがって、取付孔１０と固定部１２の間にできる隙間をより少なくし、隙間を通した外気の進入をより確実に抑制することができる。   Further, in the shock absorber 11 of this embodiment, the stopper protrusion 21 for restricting tightening is formed in the spiral groove 19 so as to protrude in a substantially arc shape along the groove direction, and therefore, even in the rotation restricting state. The rotational position of the buffer 11 can be finely adjusted relatively easily. Therefore, a partial gap formed by the eccentricity of the fixing portion 12 with respect to the mounting hole 10 can be closed by fine adjustment of the rotational position. Therefore, the gap formed between the mounting hole 10 and the fixing portion 12 can be reduced, and the entry of outside air through the gap can be more reliably suppressed.

なお、この発明は上記の実施形態に限定されるものではなく、その要旨を逸脱しない範囲で種々の設計変更が可能である。
例えば、上記の実施形態においては、シール突条２３を螺旋周壁２２の外周面に一体に形成したが、シール突条は螺旋周壁とは別の部品として製造し、シール突条の無い緩衝体に接着等によって固定するようにしても良い。この場合、シール突条の無い既存の緩衝体を流用することができることから、製造コストの低減を図ることができる。 In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary.
For example, in the above embodiment, the seal ridge 23 is integrally formed on the outer peripheral surface of the spiral peripheral wall 22, but the seal ridge is manufactured as a separate part from the spiral peripheral wall, and the shock absorber without the seal ridge is formed. You may make it fix by adhesion | attachment etc. In this case, it is possible to divert the existing buffer body without the seal protrusion, and thus it is possible to reduce the manufacturing cost.
