上記した電気部品については種々のものが提案されている。例えば、特許文献１に記載の電気部品は、図７（Ａ）の模式斜視図に示すように、車両ＢのスライドドアＤに使用されるドアクローザ１００である。ドアクローザ１００は、クローザ本体１０１をスライドドアＤの内側からインナパネルＤｅに取付けるための固定部１０４と、クローザ本体１０１を駆動させる電動モータ１０６及びクローザ本体１０１の動作状態を検出する各種スイッチ（図示省略）とを備えている。電動モータ１０６や各種スイッチの電気配線はコネクタ１０２に接続され、そのコネクタ１０２を介して電子制御ユニット（図示省略）等の他の電気部品に接続される。
コネクタ１０２は、図７（Ｂ）の平面図に示すように、樹脂製のコネクタ本体部１０２ｍと、そのコネクタ本体部１０２ｍの回りを覆うゴム製のシール部１０２ｓとを備えている。シール部１０２ｓはコネクタ本体部１０２ｍより先端側に突出する部分が軸方向に伸縮可能に構成されており、その伸縮可能部位の先端にフランジ部１０２ｆと、リング状の挿通部１０２ｒとが同軸に形成されている。そして、前記挿通部１０２ｒがインナパネルＤｅの電気配線用の貫通孔Ｄｈに通され、かつフランジ部１０２ｆがその貫通孔Ｄｈの周縁部に当接した状態で、クローザ本体１０１の固定部１０４がインナパネルＤｅに取付けられる。 Various types of electrical components have been proposed. For example, the electrical component described in Patent Document 1 is a door closer 100 used for a slide door D of a vehicle B as shown in a schematic perspective view of FIG. The door closer 100 includes a fixing portion 104 for attaching the closer body 101 to the inner panel De from the inside of the slide door D, an electric motor 106 for driving the closer body 101, and various switches for detecting the operating state of the closer body 101 (not shown). ).

特開２００５−１６３４５６号公報JP 2005-163456 A

前述のように、シール部１０２ｓはゴム製でコネクタ本体部１０２ｍより先端側に突出する部分が軸方向に伸縮可能に構成されており、その伸縮可能部位の先端にフランジ部１０２ｆと、リング状の挿通部１０２ｒとが同軸に形成されている。このため、仮に、挿通部１０２ｒがインナパネルＤｅの電気配線用の貫通孔Ｄｈに通されず、その周縁部に当接した状態であっても、シール部１０２ｓの伸縮可能部位が不自然に弾性変形することで、クローザ本体１０１の固定部１０４を無理にインナパネルＤｅに取付けることが可能である。   As described above, the seal portion 102s is made of rubber, and a portion protruding from the connector main body portion 102m toward the tip side is configured to be extendable in the axial direction. The flange portion 102f and the ring-shaped portion are provided at the tip of the extendable portion. The insertion part 102r is formed coaxially. For this reason, even if the insertion portion 102r is not passed through the through hole Dh for the electrical wiring of the inner panel De and is in contact with the peripheral portion, the stretchable portion of the seal portion 102s is unnaturally elastic. By deforming, the fixing portion 104 of the closer body 101 can be forcibly attached to the inner panel De.

本発明は、上記問題点を解決するためになされたものであり、本発明が解決しようとする課題は、シール部の挿通部が被取付け部品の電気配線用の貫通孔に通されない状態で、被取付け部品に対する電気部品本体の取付けを不能にすることにより、電気部品の誤った取付けを防止することである。   The present invention has been made to solve the above problems, and the problem to be solved by the present invention is that the insertion portion of the seal portion is not passed through the through hole for electric wiring of the mounted component. It is to prevent erroneous mounting of an electrical component by disabling the mounting of the electrical component body to the mounted component.

That is, since the electric component main body is not disposed at a regular position that can be fixed to the mounted component, the electric component main body cannot be fixed to the mounted component. For this reason, in the state where the insertion portion of the seal portion is not passed through the through-hole of the mounted component, there is no problem that the electric component main body is erroneously fixed to the mounted component.

請求項２の発明によると、シール部は、取付け部、連結部、当接部及び挿通部を構成する筒状のゴム製部と、前記ゴム製部を補強する樹脂又は金属製の筒体であって、前記連結部の弾性変形を妨げないように構成された補強部とを備えていることを特徴とする。
このため、シール部は、筒体である補強部の働きで不自然な形状に変形することがない。したがって、前記シール部の連結部が弾性変形したときの挿通部の先端から取付け部までの最小寸法を常に一定値に保持することができる。 According to the invention of claim 2, the seal part is a cylindrical rubber part that constitutes the attachment part, the connection part, the contact part and the insertion part, and a resin or metal cylinder that reinforces the rubber part. And a reinforcing portion configured so as not to hinder elastic deformation of the connecting portion.
For this reason, a seal part does not deform | transform into an unnatural shape by the effect | action of the reinforcement part which is a cylinder. Therefore, the minimum dimension from the tip of the insertion portion to the mounting portion when the connecting portion of the seal portion is elastically deformed can always be maintained at a constant value.

本発明によると、シール部の挿通部が被取付け部品の電気配線用の貫通孔に通されない状態では、電気部品本体部が被取付け部品に固定可能な正規の位置に配置されないため、電気部品本体部が被取付け部品に誤って固定されるような不具合が発生しない。   According to the present invention, in a state where the insertion portion of the seal portion is not passed through the through hole for electric wiring of the mounted component, the electric component main body portion is not disposed at a regular position that can be fixed to the mounted component. There is no problem that the part is fixed to the mounted part by mistake.

＜ドアクローザ１０の構成概要について＞
ドアクローザ１０は、車両の側面に形成された乗降口を開閉するスライドドアＤ内に固定されており（図２（Ａ）（Ｂ）参照）、そのスライドドアＤを半閉状態から電動モータの回転力で完全閉状態に移行させるための装置である。ドアクローザ１０は、図５のドアクローザ背面図に示すように、スライドドアＤのインナパネルＤｅに当接可能に構成されたブラケット１２を備えている。ブラケット１２は、インナパネルＤｅの内壁面の形状に合わせて折り曲げ成形された板状部材であり、そのインナパネルＤｅの複数のボルト孔Ｄｈ（図３参照）に対応する位置に雌ねじ孔１２ｗが形成されている。そして、前記インナパネルＤｅの外側からボルト孔Ｄｈを通してボルト（図示省略）がブラケット１２の雌ねじ孔１２ｗに螺合されることで、そのブラケット１２が前記インナパネルＤｅに固定される。
また、ブラケット１２の折り曲げ部１２ｐ中央には、図５に示すように、窓部１２ｈが形成されており、その窓部１２ｈに対して乗降口の縁部に固定されたストライカ（図示省略）がスライドドアＤを閉じる際に挿通されるように構成されている。 <About the configuration outline of the door closer 10>
The door closer 10 is fixed in a slide door D that opens and closes an entrance / exit formed on a side surface of the vehicle (see FIGS. 2A and 2B). The slide door D is rotated from the half-closed state to the electric motor. It is a device for shifting to a fully closed state by force. As shown in the rear view of the door closer in FIG. 5, the door closer 10 includes a bracket 12 configured to be able to contact the inner panel De of the sliding door D. The bracket 12 is a plate-like member that is bent according to the shape of the inner wall surface of the inner panel De, and female screw holes 12w are formed at positions corresponding to the plurality of bolt holes Dh (see FIG. 3) of the inner panel De. Has been. Then, a bolt (not shown) is screwed into the female screw hole 12w of the bracket 12 from the outside of the inner panel De through the bolt hole Dh, so that the bracket 12 is fixed to the inner panel De.
Further, as shown in FIG. 5, a window 12h is formed at the center of the bent portion 12p of the bracket 12, and a striker (not shown) fixed to the edge of the entrance for the window 12h. It is configured to be inserted when the slide door D is closed.

ブラケット１２の表側には、図６（Ｂ）のドアクローザ原理図に示すように、ロック溝２１ｍを備える鉤状のラッチ２１が支軸２１ｐを中心に回転可能な状態で取付けられている。ラッチ２１は、ブラケット１２の窓部１２ｈから挿入されたストライカがロック溝２１ｍに入り込むことで原位置から半閉位置まで左回転し、さらに後記するドリブンギヤ２３、及びパッシブレバー２４から押し下げ力を受けることで完全閉位置まで左回転するように構成されている。そして、ラッチ２１は、完全閉位置において前記ストライカとガタツキのない状態で係合する。なお、ラッチ２１は、図示省略したバネにより常に原位置に戻る方向の力（右回転力）を受けている。
また、ブラケット１２には、図６（Ａ）に示すように、ラッチ２１が半閉位置、あるいは完全閉位置まで回転したこと検知するためのラッチスイッチ２６が設けられている。
前記ラッチ２１を完全閉位置まで回転させるドリブンギヤ２３は、支軸２３ｐを中心にして回転可能な状態でブラケット１２に取付けられており、そのドリブンギヤ２３の基端部に円弧状のギヤ部２３ｗが形成されている。そして、そのギヤ部２３ｗに電動モータ３２により回転させられる構成のピニオンギヤ３２ｐが噛合している。また、ドリブンギヤ２３の先端部には、支軸２４ｐを介して回転可能な状態でパッシブレバー２４が取付けられている。これにより、電動モータ３２、ピニオンギヤ３２ｐの動作によりドリブンギヤ２３が右回転（矢印方向に回転）させられると、パッシブレバー２４が下動してラッチ２１が半閉位置から完全閉位置まで矢印方向に回転させられる。 On the front side of the bracket 12, as shown in the door closer principle diagram of FIG. 6 (B), a hook-shaped latch 21 having a lock groove 21m is attached in a state of being rotatable around a support shaft 21p. The latch 21 is rotated counterclockwise from the original position to the semi-closed position when the striker inserted from the window 12h of the bracket 12 enters the lock groove 21m, and further receives a push-down force from the driven gear 23 and the passive lever 24 described later. It is configured to rotate counterclockwise to the fully closed position. Then, the latch 21 is engaged with the striker in a fully closed position without rattling. Note that the latch 21 receives a force in the direction of returning to the original position (right rotational force) by a spring (not shown).
Further, as shown in FIG. 6A, the bracket 12 is provided with a latch switch 26 for detecting that the latch 21 has rotated to the half-closed position or the fully-closed position.
The driven gear 23 for rotating the latch 21 to the fully closed position is attached to the bracket 12 so as to be rotatable about the support shaft 23p, and an arcuate gear portion 23w is formed at the base end portion of the driven gear 23. Has been. And the pinion gear 32p of the structure rotated by the electric motor 32 is meshing | engaged with the gear part 23w. Moreover, the passive lever 24 is attached to the front-end | tip part of the driven gear 23 in the state which can rotate via the spindle 24p. Thus, when the driven gear 23 is rotated clockwise (rotated in the direction of the arrow) by the operation of the electric motor 32 and the pinion gear 32p, the passive lever 24 is moved downward and the latch 21 is rotated in the direction of the arrow from the semi-closed position to the fully closed position. Be made.

ラッチ２１の下方には、そのラッチ２１を半閉位置及び完全閉位置に保持するためのポール２５がブラケット１２に対して回転可能な状態で取付けられている。ポール２５は、ラッチ２１の半閉爪部２１ｅと係合することで、そのラッチ２１を半閉位置に保持し、前記ラッチ２１の完全閉爪部２１ｃと係合することでそのラッチ２１を完全閉位置に保持する。
また、ブラケット１２には、図６（Ａ）に示すように、スライドドアＤの開ハンドル（図示省略）とワイヤＷを介して接続されたオープンレバー２８が回転可能に装着されている。そして、オープンレバー２８がワイヤＷに引かれて図６（Ａ）において左回転することにより、前記ポール２５がオープンレバー２８と係合して解錠方向に回転し、そのポール２５とラッチ２１との係合が解除される。また、オープンレバー２８の近傍には、スライドドアＤの開ハンドルによってオープンレバー２８が動作させられたか否かを検出するためのオープンスイッチ２９が取付けられている。 Below the latch 21, a pole 25 for holding the latch 21 in the semi-closed position and the fully-closed position is attached to the bracket 12 in a rotatable state. The pawl 25 engages with the semi-closed claw portion 21e of the latch 21 to hold the latch 21 in the semi-closed position, and engages with the fully-closed claw portion 21c of the latch 21 to completely fix the latch 21. Hold in closed position.
Further, as shown in FIG. 6A, an open lever 28 connected to an open handle (not shown) of the slide door D via a wire W is rotatably mounted on the bracket 12. Then, when the open lever 28 is pulled by the wire W and rotates counterclockwise in FIG. 6A, the pawl 25 engages with the open lever 28 and rotates in the unlocking direction. Is disengaged. Further, an open switch 29 for detecting whether or not the open lever 28 is operated by the open handle of the slide door D is attached in the vicinity of the open lever 28.

＜ドアクローザ１０の動作について＞
スライドドアＤが閉じられてドアクローザ１０のブラケット１２の窓部１２ｈから前記ストライカがラッチ２１のロック溝２１ｍに入り込むと、ラッチ２１はストライカに押圧されて半閉位置まで回転する。そして、ラッチ２１の半閉爪部２１ｅがポール２５と係合することで、ラッチ２１はこの半閉位置に保持される。この状態がラッチスイッチ２６によって検出されると、電動モータ３２が正転してピニオンギヤ３２ｐが回転し、ドリブンギヤ２３が右回転（矢印方向に回転）させられる。これによって、パッシブレバー２４が下動してラッチ２１が半閉位置から完全閉位置まで矢印方向に回転し、ラッチ２１は前記ストライカとガタツキのない状態で係合する。さらに、ラッチ２１の完全閉爪部２１ｃがポール２５と係合することで、ラッチ２１はこの完全閉位置に保持される。
ラッチ２１が完全閉位置に保持されると、これがラッチスイッチ２６によって検出され、これに基づいて電動モータ３２が逆転する。これによって、ドリブンギヤ２３が左回転させられ、そのドリブンギヤ２３がパッシブレバー２４と共に初期位置まで戻される。
次に、スライドドアＤを開く際に、開ハンドル（図示省略）を操作することでオープンレバー２８が左回転させられると、そのオープンレバー２８によってポール２５が解錠方向に回転させられ、そのポール２５とラッチ２１の係合が解除される。これによって、ラッチ２１はバネの力で原位置まで戻され、そのラッチ２１と前記ストライカとの係合が解除される。
即ち、ドアクローザ１０が本発明の電気部品に相当し、ブラケット１２が本発明の電気部品の固定部に相当する。また、ブラケット１２の表側に取付けられた電動モータ３２、ラッチ２１等、及び各種スイッチ等が本発明の電気部品本体部に相当する。さらに、スライドドアＤのインナパネルＤｅが本発明の被取付け部品に相当する。 <About the operation of the door closer 10>
When the slide door D is closed and the striker enters the lock groove 21m of the latch 21 from the window portion 12h of the bracket 12 of the door closer 10, the latch 21 is pressed by the striker and rotates to the semi-closed position. And the latch 21 is hold | maintained in this semi-closed position because the semi-closed claw part 21e of the latch 21 engages with the pole 25. FIG. When this state is detected by the latch switch 26, the electric motor 32 rotates forward, the pinion gear 32p rotates, and the driven gear 23 rotates clockwise (rotates in the direction of the arrow). As a result, the passive lever 24 moves downward and the latch 21 rotates in the direction of the arrow from the half-closed position to the fully-closed position, and the latch 21 engages with the striker without any backlash. Furthermore, when the fully closed claw portion 21c of the latch 21 is engaged with the pole 25, the latch 21 is held in this fully closed position.
When the latch 21 is held in the fully closed position, this is detected by the latch switch 26, and based on this, the electric motor 32 is reversed. As a result, the driven gear 23 is rotated counterclockwise, and the driven gear 23 is returned to the initial position together with the passive lever 24.
Next, when opening the slide door D, if the open lever 28 is rotated counterclockwise by operating an opening handle (not shown), the pole 25 is rotated in the unlocking direction by the open lever 28, and the pole 25 and the latch 21 are disengaged. Thereby, the latch 21 is returned to the original position by the force of the spring, and the engagement between the latch 21 and the striker is released.
That is, the door closer 10 corresponds to the electrical component of the present invention, and the bracket 12 corresponds to the fixing part of the electrical component of the present invention. Further, the electric motor 32, the latch 21 and the like, and various switches attached to the front side of the bracket 12 correspond to the electric component main body of the present invention. Further, the inner panel De of the slide door D corresponds to the mounted part of the present invention.

ドアクローザ１０の電動モータ３２のハウジング３２ｚには、その電動モータ３２の電気配線と、ラッチスイッチ２５及びオープンスイッチ２９の電気配線が接続される樹脂製のコネクタ部４０が設けられている。コネクタ部４０には、電子制御ユニット（図示省略）等からの電気配線の一端に接続されたコネクタ（図示省略）がスライドドアＤのインナパネルＤｅに形成された電気配線用の貫通孔４５（図１、図３等参照）を通して接続される。
コネクタ部４０は、図１（Ａ）（Ｂ）に示すように、ゴム製のシール部５０によって覆われている。シール部５０は、コネクタ部４０の外周面を覆うとともに、そのコネクタ部４０とインナパネルＤｅの貫通孔４５とを周囲からシールした状態でつなぐ部分であり、略筒状に形成されている。
シール部５０は、コネクタ部４０の外周面を覆うことでそのコネクタ部４０に取付けられる取付け部５２と、コネクタ部４０の先端面４３から軸方向に突出する突出部分５３，５５，５７とを備えている。そして、シール部５０の突出部分５３，５５，５７に、先端側から順番にリング状の挿通部５７と、フランジ状の当接部５５と、軸方向に変形可能な構成の連結部５３とが同軸に形成されている。挿通部５７は、インナパネルＤｅの貫通孔４５に挿通される部分であり、その挿通部５７の外径寸法は貫通孔４５の内径寸法よりも小さく設定されている。当接部５５は、挿通部５７がインナパネルＤｅの貫通孔４５に挿通された状態で、その貫通孔４５の周縁部に当接する部分であり、貫通孔４５とシール部５０間のシール性を確保する働きをする。連結部５３は、軸方向に変形可能に構成されることで、取付け部５２の先端面５２ｆ（コネクタ部４０の先端面４３と軸方向において同位置）からインナパネルＤｅの貫通孔４５の周縁部までの距離と、その取付け部５２の先端面５２ｆからシール部５０の当接部５５までの距離の違いを吸収する働きをする。 <Connector part and seal part of door closer 10>
The housing 32z of the electric motor 32 of the door closer 10 is provided with a resin connector 40 to which the electric wiring of the electric motor 32 and the electric wiring of the latch switch 25 and the open switch 29 are connected. In the connector portion 40, a connector (not shown) connected to one end of an electrical wiring from an electronic control unit (not shown) or the like is a through hole 45 for electrical wiring (not shown) formed in the inner panel De of the slide door D. 1, see FIG. 3).
The connector 40 is covered with a rubber seal 50 as shown in FIGS. The seal portion 50 is a portion that covers the outer peripheral surface of the connector portion 40 and connects the connector portion 40 and the through hole 45 of the inner panel De in a sealed state from the periphery, and is formed in a substantially cylindrical shape.
The seal portion 50 includes an attachment portion 52 that is attached to the connector portion 40 by covering the outer peripheral surface of the connector portion 40, and protruding portions 53, 55, 57 that protrude in the axial direction from the distal end surface 43 of the connector portion 40. ing. And in the protrusion parts 53, 55, 57 of the seal part 50, a ring-shaped insertion part 57, a flange-shaped contact part 55, and a connecting part 53 configured to be deformable in the axial direction are arranged in order from the tip side. It is formed coaxially. The insertion portion 57 is a portion that is inserted into the through hole 45 of the inner panel De, and the outer diameter dimension of the insertion portion 57 is set smaller than the inner diameter dimension of the through hole 45. The abutting portion 55 is a portion that abuts on the peripheral portion of the through hole 45 in a state where the insertion portion 57 is inserted into the through hole 45 of the inner panel De, and provides a sealing property between the through hole 45 and the seal portion 50. Work to secure. Since the connecting portion 53 is configured to be deformable in the axial direction, the peripheral portion of the through hole 45 of the inner panel De from the front end surface 52f of the mounting portion 52 (same position in the axial direction as the front end surface 43 of the connector portion 40). And the distance from the front end surface 52f of the mounting portion 52 to the contact portion 55 of the seal portion 50 is absorbed.

シール部５０には、図１（Ａ）（Ｂ）に示すように、挿通部５７と当接部５５との内周側に補強部６０が固定されている。補強部６０は、挿通部５７と当接部５５との変形を防止するとともに、挿通部５７の先端６３からコネクタ部４０の先端面４３までの最小寸法を一定値Ｊに保持するための筒状体である。補強部６０は、挿通部５７と当接部５５との内周面を覆う円筒部６２と、その円筒部６２の先端に形成されて前記挿通部５７の先端面５７ｆを覆うフランジ部６３とから構成されている。また、補強部６０における円筒部６２の基端部側には、連結部５３の形状に合わせて拡開部６２ｗが形成されている。補強部６０は、変形し難い樹脂又は金属により形成されており、その軸長寸法は寸法Ｊに設定されている。このため、シール部５０の先端６３（補強部６０のフランジ部６３）が軸方向から押圧力を受けても、挿通部５７と当接部５５は変形せず、連結部５３のみが軸長寸法を減少させる方向に変形する。そして、シール部５０の連結部５３の変形により、補強部６０の拡開部６２ｗが取付け部５２の先端面５２ｆに当接すると、取付け部５２の先端面５２ｆ（コネクタ部４０の先端面４３）とシール部５０の先端６３間の距離が寸法Ｊに等しくなる（図１（Ａ）参照）。即ち、シール部５０の先端６３が軸方向の押圧力を受けても、シール部５０の先端６３から取付け部５２の先端面５２ｆ（コネクタ部４０の先端面４３）までの距離は寸法Ｊ（最小寸法）よりも小さくなることはない。   As shown in FIGS. 1A and 1B, a reinforcing portion 60 is fixed to the seal portion 50 on the inner peripheral side of the insertion portion 57 and the contact portion 55. The reinforcing portion 60 prevents the deformation of the insertion portion 57 and the abutting portion 55 and also has a cylindrical shape for holding the minimum dimension from the distal end 63 of the insertion portion 57 to the distal end surface 43 of the connector portion 40 at a constant value J. Is the body. The reinforcing portion 60 includes a cylindrical portion 62 that covers the inner peripheral surfaces of the insertion portion 57 and the contact portion 55, and a flange portion 63 that is formed at the distal end of the cylindrical portion 62 and covers the distal end surface 57 f of the insertion portion 57. It is configured. Further, on the proximal end side of the cylindrical portion 62 in the reinforcing portion 60, an expanded portion 62w is formed in accordance with the shape of the connecting portion 53. The reinforcing portion 60 is made of a resin or metal that is not easily deformed, and its axial length dimension is set to a dimension J. For this reason, even if the distal end 63 of the seal portion 50 (the flange portion 63 of the reinforcing portion 60) receives a pressing force from the axial direction, the insertion portion 57 and the contact portion 55 are not deformed, and only the connecting portion 53 has an axial length dimension. It will be deformed in the direction of decreasing. And if the expansion part 62w of the reinforcement part 60 contact | abuts to the front end surface 52f of the attachment part 52 by deformation | transformation of the connection part 53 of the seal | sticker part 50, the front end surface 52f of the attachment part 52 (front end surface 43 of the connector part 40). And the distance between the front-end | tip 63 of the seal | sticker part 50 becomes equal to the dimension J (refer FIG. 1 (A)). That is, even if the tip 63 of the seal portion 50 receives an axial pressing force, the distance from the tip 63 of the seal portion 50 to the tip surface 52f of the attachment portion 52 (tip surface 43 of the connector portion 40) is the dimension J (minimum). Dimension) is never smaller.

＜ドアクローザ１０の固定について＞
ドアクローザ１０は、図１（Ｂ）及び図３に示すように、シール部５０の挿通部５７をインナパネルＤｅの貫通孔４５に通し、そのシール部５０の当接部５５を貫通孔４５の周縁部に当接させた状態で、ブラケット１２の雌ねじ孔１２ｗがインナパネルＤｅのボルト孔Ｄｈ（図３参照）に位置合わせされる。そして、インナパネルＤｅの外側からボルト孔Ｄｈを通してボルト（図示省略）がブラケット１２の雌ねじ孔１２ｗに螺合されることで、ドアクローザ１０はインナパネルＤｅに固定される。ドアクローザ１０がインナパネルＤｅに正しく固定されたときのコネクタ部４０の先端面４３とインナパネルＤｅの貫通孔４５の周縁部との間の距離をＳ（図１（Ｂ）参照）とすると、シール部５０の補強部６０の軸長寸法Ｊは、距離Ｓよりも十分大きな値に設定されている。したがって、図１（Ａ）、図４に示すように、シール部５０の挿通部５７の先端６３がインナパネルＤｅの貫通孔４５の周縁部に当接した状態では、ドアクローザ１０がインナパネルＤｅに固定される位置に位置決めされることはない。 <Fixing the door closer 10>
As shown in FIG. 1B and FIG. 3, the door closer 10 passes the insertion portion 57 of the seal portion 50 through the through hole 45 of the inner panel De, and the contact portion 55 of the seal portion 50 is the periphery of the through hole 45. The female screw hole 12w of the bracket 12 is aligned with the bolt hole Dh (see FIG. 3) of the inner panel De in a state of being in contact with the portion. Then, a bolt (not shown) is screwed into the female screw hole 12w of the bracket 12 from the outside of the inner panel De through the bolt hole Dh, whereby the door closer 10 is fixed to the inner panel De. When the distance between the distal end surface 43 of the connector portion 40 and the peripheral edge portion of the through hole 45 of the inner panel De when the door closer 10 is correctly fixed to the inner panel De is S (see FIG. 1B), the seal The axial length dimension J of the reinforcing part 60 of the part 50 is set to a value sufficiently larger than the distance S. Therefore, as shown in FIG. 1A and FIG. 4, when the tip 63 of the insertion portion 57 of the seal portion 50 is in contact with the peripheral edge of the through hole 45 of the inner panel De, the door closer 10 is attached to the inner panel De. It is not positioned at a fixed position.

＜本実施形態に係るドアクローザ１０の長所について＞
本実施形態に係るドアクローザ１０によると、シール部５０の連結部５３が軸方向の寸法を減少させる方向に弾性変形したときの挿通部５７の先端６３から取付け部５２までの最小寸法Ｊが、ドアクローザ１０をインナパネルＤｅに固定したときの取付け部５２からインナパネルＤｅの貫通孔４５の周縁部までの距離Ｓよりも大きく設定されている（図１（Ｂ）参照）。このため、シール部５０の挿通部５７の先端６３が貫通孔４５の周縁部に当接した状態（図１（Ａ）、図４参照）、即ち、シール部５０の挿通部５７がインナパネルＤｅの貫通孔４５に通されない状態では、シール部５０の取付け部５２に連結されるコネクタ部４０が正規の位置に配置されることがない。即ち、コネクタ部４０を備えるドアクローザ１０がインナパネルＤｅに固定可能な正規の位置に配置されない（図４参照）。このため、ドアクローザ１０のブラケット１２に設けられた雌ネジ孔１２ｗの位置と、インナパネルＤｅのボルト孔Ｄｈの位置とがずれて、そのドアクローザ１０をインナパネルＤｅにボルト固定することができなくなる。したがって、シール部５０の挿通部５７がインナパネルＤｅの貫通孔４５に通されない状態で、誤ってドアクローザ１０がインナパネルＤｅに固定されるような不具合が発生しない。
また、シール部５０は、筒体である補強部６０の働きで不自然な形状に変形することがない。したがって、シール部５０の連結部５３が弾性変形したときの挿通部５７の先端６３からコネクタ部４０までの最小寸法Ｊを一定値に保持することができる。 <Advantages of the door closer 10 according to this embodiment>
According to the door closer 10 according to the present embodiment, the minimum dimension J from the distal end 63 of the insertion portion 57 to the mounting portion 52 when the connecting portion 53 of the seal portion 50 is elastically deformed in a direction to reduce the axial dimension is the door closer. It is set to be larger than the distance S from the attachment portion 52 when the 10 is fixed to the inner panel De to the peripheral edge portion of the through hole 45 of the inner panel De (see FIG. 1B). Therefore, the state in which the tip 63 of the insertion portion 57 of the seal portion 50 is in contact with the peripheral portion of the through hole 45 (see FIG. 1A and FIG. 4), that is, the insertion portion 57 of the seal portion 50 is the inner panel De. In a state where it is not passed through the through-hole 45, the connector portion 40 connected to the attachment portion 52 of the seal portion 50 is not disposed at a proper position. That is, the door closer 10 including the connector portion 40 is not disposed at a regular position that can be fixed to the inner panel De (see FIG. 4). For this reason, the position of the female screw hole 12w provided in the bracket 12 of the door closer 10 and the position of the bolt hole Dh of the inner panel De shift, and the door closer 10 cannot be bolted to the inner panel De. Therefore, there is no problem that the door closer 10 is erroneously fixed to the inner panel De in a state where the insertion portion 57 of the seal portion 50 is not passed through the through hole 45 of the inner panel De.
Further, the seal portion 50 is not deformed into an unnatural shape by the function of the reinforcing portion 60 that is a cylindrical body. Therefore, the minimum dimension J from the tip 63 of the insertion portion 57 to the connector portion 40 when the connecting portion 53 of the seal portion 50 is elastically deformed can be held at a constant value.
