Refuel or fill with hydrogen by inserting a fill plug into the fill port. When charging an electric vehicle or PHV (plug-in hybrid vehicle) with electricity, the charging lid is opened, the cap of the quick charging port or normal charging port is removed, and the charging connector is inserted into the charging port for charging.

この種の蓋の取付け構造として、特許文献１に開示された技術を図１から図５に基づいて説明する。蓋１０（給油口蓋）の裏面１２には、アーム部材２０が取付けられている。アーム部材２０は、円弧状に湾曲した板状であり、その先端部分には、ボックス３０（給油口ボックス）に取付けられる部分であるボックス取付部２４を有している。 As a lid mounting structure of this type, the technique disclosed in Patent Document 1 will be described with reference to FIGS. 1 to 5. FIG. An arm member 20 is attached to the rear surface 12 of the lid 10 (fuel cap). The arm member 20 has a plate-like shape curved in an arc shape, and has a box attachment portion 24 at its tip portion, which is a portion attached to the box 30 (filler port box).

アーム部材２０のボックス取付部２４は、図４に示すように、ボックス３０のアーム部材係合部３５０（図３）に係合するアーム部材２０のボックス係合ピン２５０が形成されている。ボックス係合ピン２５０は、ボックス取付部２４の先端の両側面に形成されている。 As shown in FIG. 4, the box mounting portion 24 of the arm member 20 is formed with a box engaging pin 250 of the arm member 20 that engages with the arm member engaging portion 350 (FIG. 3) of the box 30. As shown in FIG. The box engaging pins 250 are formed on both side surfaces of the tip of the box attachment portion 24 .

一方、ボックス３０は、図１と図２に示すように、底部の中心に車体２の給油口１と連通する給油ガンを挿入する給油孔３６（開口部）を有するボックス本体部３１とアーム部材２０を収納するアーム部材収納部３７を有し、ボックス３０は、シール部材３３を介して車体２のボックス保持部３に取付けられている。アーム部材収納部３７は、車体２のボックス保持部３が形成されている部分よりも車体２の内側（図１における左側）に入り込んで形成されている。 On the other hand, as shown in FIGS. 1 and 2, the box 30 has a box main body 31 having a refueling hole 36 (opening) in the center of the bottom for inserting a refueling gun communicating with the refueling port 1 of the vehicle body 2, and an arm member. The box 30 is attached to the box holding portion 3 of the vehicle body 2 via the sealing member 33 . The arm member storage portion 37 is formed so as to enter the inside of the vehicle body 2 (left side in FIG. 1) from the portion of the vehicle body 2 where the box holding portion 3 is formed.

図３に示すように、アーム部材収納部３７には、アーム部材係合部３５０までアーム部材２０のボックス係合ピン２５０を案内するアーム部材ガイド部３４が形成されており、アーム部材ガイド部３４の先端部分には、アーム部材２０のボックス係合ピン２５０を係合するアーム部材係合部３５０が形成されている。 As shown in FIG. 3 , arm member guide portion 34 for guiding box engagement pin 250 of arm member 20 to arm member engagement portion 350 is formed in arm member storage portion 37 . An arm member engaging portion 350 for engaging the box engaging pin 250 of the arm member 20 is formed at the tip portion of the arm member 20 .

アーム部材ガイド部３４を形成したため、アーム部材２０をボックス３０に取付けるときに、アーム部材ガイド部３４の中にアーム部材２０のボックス係合ピン２５０を挿入して、摺動することにより、ボックス３０のアーム部材収納部３７の奥が見にくくても、容易にアーム部材２０をボックス３０に組み付けることができる。 Since the arm member guide portion 34 is formed, when the arm member 20 is attached to the box 30, the box 30 can be attached by inserting the box engaging pin 250 of the arm member 20 into the arm member guide portion 34 and sliding. The arm member 20 can be easily assembled to the box 30 even if the depth of the arm member storage portion 37 is difficult to see.

ボックス取付部２４の凸部２５が通過するアーム部材ガイド部３４の幅は、凸部２５の直径より少し大きく形成され、凸部２５が通過しやすくなっている。又、アーム部材ガイド部３４と凸部受け部３５の連結部には、凸部２５の直径よりわずかに小さい幅となるような両側が窪んだ狭幅部３４ａが形成されている。凸部２５を狭幅部３４ａに押し込み、狭幅部３４ａが少し撓んで凸部２５を通過させることにより凸部受け部３５に凸部２５を嵌め込むと共に凸部２５が凸部受け部３５から外れることを防止できる。なお、アーム部材ガイド部３４の凸部受け部３５の幅は、凸部２５の直径とほぼ同じに形成され、凸部受け部３５内における凸部２５のズレを抑えている。 The width of the arm member guide portion 34 through which the convex portion 25 of the box mounting portion 24 passes is slightly larger than the diameter of the convex portion 25 so that the convex portion 25 can easily pass through. A connecting portion between the arm member guide portion 34 and the convex portion receiving portion 35 is formed with a narrow width portion 34 a having a width slightly smaller than the diameter of the convex portion 25 and recessed on both sides. The convex portion 25 is pushed into the narrow portion 34a, and the narrow portion 34a is slightly bent to allow the convex portion 25 to pass through. You can prevent it from coming off. The width of the projection receiving portion 35 of the arm member guide portion 34 is formed to be substantially the same as the diameter of the projection 25, thereby suppressing displacement of the projection 25 within the projection receiving portion 35. FIG.

又、ボックス３０のアーム部材ガイド部３４と凸部受け部３５の連結部の狭幅部３４ａが形成されている場所の外面から内部方向（狭幅部３４ａと直交する方向）には、ボックス本体部３１側に傾斜面を有する突起部３４ｂが形成されている。 In addition, from the outer surface of the place where the narrow width portion 34a of the connecting portion between the arm member guide portion 34 and the convex portion receiving portion 35 of the box 30 is formed, the box main body A projecting portion 34b having an inclined surface is formed on the portion 31 side.

図４に示すように、アーム部材２０のボックス取付部２４の一方の側面２４ａには、円柱形状に突出して凸部２５が形成されている。又、その先端部分は斜面状に切りかかれた凸部斜面２５ａが形成されている。凸部斜面２５ａにより凸部２５がアーム部材ガイド部３４の突起部３４ｂを乗り越えやすくなるので、アーム部材２０をボックス３０の凸部受け部３５に取付けやすい。なお、凸部斜面２５ａは形成しなくてもよい。 As shown in FIG. 4, one side surface 24a of the box mounting portion 24 of the arm member 20 is formed with a convex portion 25 protruding in a cylindrical shape. Further, a convex slope 25a is formed at the tip portion thereof by cutting in the shape of a slope. Since the protrusion slope 25 a makes it easier for the protrusion 25 to climb over the protrusion 34 b of the arm member guide section 34 , the arm member 20 can be easily attached to the protrusion receiving section 35 of the box 30 . Note that the convex slope 25a may not be formed.

一方、図６に示すように、ボックス取付部２４の他方の側面２４ｂには、反対側の側面に形成されている凸部２５と同軸に円柱形状の凹部２６が形成されている。 On the other hand, as shown in FIG. 6, the other side surface 24b of the box mounting portion 24 is formed with a cylindrical concave portion 26 coaxially with the convex portion 25 formed on the opposite side surface.

図７と図９に示すように、アーム部材収納部３７の他方の側面３７ｂには、ボックス取付部２４の凹部２６に合致する位置に、断面が円形の筒状に突出した凹部受け部３８が形成されている。又、凹部受け部３８の先端部分には、後述するキャップ４０の第１係合凸部４３と係合する先端溝部３８ａが１カ所形成されている。なお、先端溝部３８ａは１カ所には限定されない。 As shown in FIGS. 7 and 9, on the other side surface 37b of the arm member housing portion 37, a concave portion receiving portion 38 protruding in a tubular shape having a circular cross section is provided at a position corresponding to the concave portion 26 of the box mounting portion 24. formed. A tip groove portion 38a that engages with a first engagement projection 43 of the cap 40, which will be described later, is formed at the tip portion of the recess receiving portion 38 at one location. Note that the tip groove portion 38a is not limited to one location.

図９に示すように、凹部受け部３８の内側面は、ボックス取付部２４側に形成された小径部３８ｂと、小径部３８ｂより直径が大きな大径部３８ｄと、小径部３８ｂと大径部３８ｄを連結する傾斜部３８ｃが同軸に形成され、大径部３８ｄには、周状に内側溝部３８ｅが形成されている。 As shown in FIG. 9, the inner surface of the recess receiving portion 38 includes a small-diameter portion 38b formed on the box mounting portion 24 side, a large-diameter portion 38d having a larger diameter than the small-diameter portion 38b, a small-diameter portion 38b and a large-diameter portion. A slanted portion 38c connecting the 38d is formed coaxially, and an inner groove portion 38e is formed in a circumferential shape in the large diameter portion 38d.

図７、図８と図９に示すように、アーム部材収納部３７の凹部受け部３８を貫通し、ボックス取付部２４の凹部２６内に挿入され、係合して嵌め込まれるキャップ４０は、凹部受け部３８を貫通する胴部４１と、凹部受け部３８の先端溝部３８ａに係合する第１係合凸部４３が形成された鍔部４２を有している。キャップ４０の鍔部４２の直径は、胴部４１の直径より大きい。 As shown in FIGS. 7, 8 and 9, a cap 40 that passes through the recess receiving portion 38 of the arm member housing portion 37 and is inserted into and engaged with the recess 26 of the box mounting portion 24 is fitted into the recess. It has a body portion 41 passing through the receiving portion 38 and a flange portion 42 formed with a first engaging projection 43 that engages with the tip groove portion 38a of the recessed receiving portion 38 . The diameter of the collar portion 42 of the cap 40 is larger than the diameter of the body portion 41 .

胴部４１は、凹部受け部３８の小径部３８ｂを貫通し、ボックス取付部２４の凹部２６に挿入されてボックス取付部２４と係合する第１胴部４１ａと、凹部受け部３８の大径部３８ｄを貫通する第２胴部４１ｂと、凹部受け部３８の傾斜部３８ｃを貫通する第３胴部４１ｃが同軸に形成されている。 The body portion 41 includes a first body portion 41a which passes through the small diameter portion 38b of the recess receiving portion 38, is inserted into the recess 26 of the box mounting portion 24 and engages with the box mounting portion 24, and the large diameter portion of the recess receiving portion 38. A second trunk portion 41b penetrating through the portion 38d and a third trunk portion 41c penetrating through the inclined portion 38c of the recess receiving portion 38 are coaxially formed.

図９に示すように、第１胴部４１ａ、第２胴部４１ｂ、第３胴部４１ｃと鍔部４２は、鍔部４２側に開口を有する空洞部４６が形成されており、この空洞部４６により、内側方向の若干の変形を許容し、キャップ４０を凹部受け部３８に嵌め込み易くしている。又、同時に、キャップ４０の軽量化を図ることができる。なお、キャップ４０の空洞部４６を形成せず、中実としてもよい。 As shown in FIG. 9, the first trunk portion 41a, the second trunk portion 41b, the third trunk portion 41c, and the collar portion 42 are formed with a hollow portion 46 having an opening on the collar portion 42 side. 46 allows for slight deformation in the inward direction, making it easier to fit the cap 40 into the recess receiving portion 38 . At the same time, the weight of the cap 40 can be reduced. Note that the hollow portion 46 of the cap 40 may not be formed and may be solid.

ここで、図９の四角内の拡大図に示したように、凹部受け部３８の小径部３８ｂと傾斜部３８ｃとの角度αは、キャップ４０の第１胴部４１ａと第３胴部４１ｃとの角度βより大きい。これにより、キャップ４０の長さと凹部受け部３８の突出長さを短く形成することができ、キャップ４０と凹部受け部３８を軽量化することができる。 Here, as shown in the enlarged view of the square in FIG. 9, the angle .alpha. is greater than the angle β of As a result, the length of the cap 40 and the projection length of the recess receiving portion 38 can be shortened, and the weight of the cap 40 and the recess receiving portion 38 can be reduced.

又、第２胴部４１ｂには、凹部受け部３８の内側溝部３８ｅに係合する第２係合凸部４４が形成されている。なお、特許請求の範囲の請求項４に記載された「係合凸部」は、本実施形態では「第２係合凸部４４」が該当する。第２係合凸部４４は、キャップ４０が凹部受け部３８に嵌め込まれた時に凹部受け部３８の内側溝部３８ｅに合致する位置に形成されている。 A second engagement protrusion 44 that engages with the inner groove portion 38e of the recess receiving portion 38 is formed on the second trunk portion 41b. In addition, the "engagement convex part" described in claim 4 of the scope of claims corresponds to the "second engagement convex part 44" in this embodiment. The second engagement projection 44 is formed at a position that matches the inner groove 38e of the recess receiving portion 38 when the cap 40 is fitted into the recess receiving portion 38. As shown in FIG.

更に、第３胴部４１ｃには、図８と図９に示すように、先端部分が先細り形状に突出するシール部４５が周状に形成されている。シール部４５の形状は、外側面４５ａが凸状の円弧形状を有し、下方に向かい第１胴部４１ａに近づく形状となっている。一方、内側面４５ｂは、第１胴部４１ａと略平行に形成されている。これによって、シール部４５の先端がアーム部材収納部３７の凹部受け部３８の傾斜部３８ｃに接触し、更にキャップ４０が押し込まれたときに、傾斜部３８ｃの傾斜に沿って、第１胴部４１ａ側に撓むように変形して傾斜部３８ｃに弾接して、シール部４５と傾斜部３８ｃとの間を確実にシールする。 Further, as shown in FIGS. 8 and 9, the third body portion 41c is formed with a circumferential seal portion 45 having a tapered tip portion. The shape of the seal portion 45 is such that the outer side surface 45a has a convex circular arc shape and is downwardly approached to the first body portion 41a. On the other hand, the inner side surface 45b is formed substantially parallel to the first body portion 41a. As a result, the tip of the seal portion 45 comes into contact with the inclined portion 38c of the recess receiving portion 38 of the arm member housing portion 37, and when the cap 40 is further pushed in, the first body portion is moved along the inclination of the inclined portion 38c. It deforms so as to bend toward 41a and elastically contacts the inclined portion 38c, thereby reliably sealing between the seal portion 45 and the inclined portion 38c.

なお、シール部４５のヒレ形状は、シール部４５の先端がアーム部材収納部３７の凹部受け部３８の傾斜部３８ｃに接触し、更にキャップ４０が押し込まれたときに、傾斜部３８ｃの傾斜に沿って、第１胴部４１ａ側に撓むことが可能であれば、外側面４５ａが凸状の円弧形状を有し、下方に向かい第１胴部４１ａに近づく形状には限定されない。例えば、図８において、（１）外側面４５ａ、内側面４５ｂが共に直線的に下方に向かい第１胴部４１ａに近づく形状、（２）外側面４５ａが下方に垂直に延び、内側面４５ｂが第１胴部４１ａから離れる方向に延びる形状なども可能である。 The fin shape of the seal portion 45 is such that when the tip of the seal portion 45 contacts the inclined portion 38c of the recess receiving portion 38 of the arm member housing portion 37 and the cap 40 is further pushed in, the inclined portion 38c is inclined. As long as it is possible to bend toward the first trunk portion 41a, the shape of the outer side surface 45a is not limited to a shape that has a convex circular arc shape and approaches the first trunk portion 41a downward. For example, in FIG. 8, (1) the outer side surface 45a and the inner side surface 45b both extend linearly downward and approach the first body portion 41a, and (2) the outer side surface 45a extends vertically downward and the inner side surface 45b extends downward. A shape that extends away from the first trunk portion 41a is also possible.

本実施形態では、アーム部材２０はナイロンを使用し、キャップ４０はＰＰ（ポリプロピレン）を使用した。ボックス取付部２４の凹部２６（ナイロン）には、キャップ４０の第１胴部４１ａ（ポリプロピレン）が挿入され、ボックス取付部２４が回動するが、両部材が異なる材料で構成されているので、係合するキャップ４０の第１胴部４１ａとボックス取付部２４の凹部２６の双方が摩耗し、経時的にがたつきが発生することを防止することができる。なお、アーム部材２０とキャップ４０の材料は、異なっていれば良く、上記のナイロンとＰＰには限定されない。 In this embodiment, the arm member 20 uses nylon, and the cap 40 uses PP (polypropylene). The first trunk portion 41a (polypropylene) of the cap 40 is inserted into the concave portion 26 (nylon) of the box mounting portion 24, and the box mounting portion 24 rotates. It is possible to prevent both the first barrel portion 41a of the cap 40 and the concave portion 26 of the box attachment portion 24, which are engaged with each other, from wearing out and rattling over time. The materials of the arm member 20 and the cap 40 are not limited to nylon and PP as long as they are different.

次に、ボックス３０のアーム部材収納部３７へのアーム部材２０の取付けについて以下に説明する。まず、アーム部材２０のボックス取付部２４側をボックス３０のボックス本体部３１側からアーム部材収納部３７に挿入する。同時に、ボックス取付部２４の凸部２５をアーム部材収納部３７のボックス取付部２４のアーム部材ガイド部３４に挿入する。 Next, attachment of the arm member 20 to the arm member storage portion 37 of the box 30 will be described below. First, the box attachment portion 24 side of the arm member 20 is inserted into the arm member storage portion 37 from the box body portion 31 side of the box 30 . At the same time, the convex portion 25 of the box mounting portion 24 is inserted into the arm member guide portion 34 of the box mounting portion 24 of the arm member storage portion 37 .

アーム部材ガイド部３４に沿ってボックス取付部２４の凸部２５を摺動させると、凸部２５は、凸部２５の直径よりわずかに小さい幅となるような両側が窪んだ狭幅部３４ａと内部方向（狭幅部３４ａと直交する方向）に突出する突起部３４ｂに当接する。そして、凸部２５を更に押し込みと狭幅部３４ａが少し撓むとともに、凸部２５が突起部３４ｂを乗り越えて通過し、その奥にある凸部受け部３５に入る。この時、凸部２５が形成されたボックス取付部２４の反対の側面２４ｂには凹部２６が同軸に形成されており、対向するアーム部材収納部３７の側面３７ｂには凹部受け部３８が形成されている。 When the convex portion 25 of the box mounting portion 24 is slid along the arm member guide portion 34, the convex portion 25 has a width slightly smaller than the diameter of the convex portion 25 and has a narrow width portion 34a recessed on both sides. It abuts on the projecting portion 34b projecting inward (direction perpendicular to the narrow portion 34a). Then, the convex portion 25 is pushed further and the narrow width portion 34a is slightly bent, and the convex portion 25 passes over the projection portion 34b and enters the convex portion receiving portion 35 behind it. At this time, a concave portion 26 is coaxially formed on the opposite side surface 24b of the box mounting portion 24 on which the convex portion 25 is formed, and a concave receiving portion 38 is formed on the opposing side surface 37b of the arm member housing portion 37. ing.

次に、凹部受け部３８に、キャップ４０の胴部４１を第１胴部４１ａ側から挿入する。第１胴部４１ａは、凹部受け部３８の大径部３８ｄ、傾斜部３８ｃと小径部３８ｂを通過し、アーム部材２０のボックス取付部２４の凹部２６に挿入される。このボックス取付部２４の凹部２６への挿入の前後（これは前又は後のどちらでも良い）に、キャップ４０の第２胴部４１ｂに形成された第２係合凸部４４が凹部受け部３８の先端部に当接する。 Next, the trunk portion 41 of the cap 40 is inserted into the recess receiving portion 38 from the first trunk portion 41a side. The first trunk portion 41 a passes through the large diameter portion 38 d , the inclined portion 38 c and the small diameter portion 38 b of the recess receiving portion 38 and is inserted into the recess 26 of the box mounting portion 24 of the arm member 20 . Before and after the box mounting portion 24 is inserted into the recess 26 (this may be either before or after), the second engaging protrusion 44 formed on the second body portion 41b of the cap 40 engages with the recess receiving portion 38. abuts on the tip of the

キャップ４０を更に押し込むと、第２係合凸部４４は撓み、大径部３８ｄ内を摺動する。そして、キャップ４０の鍔部４２に形成された第１係合凸部４３が、凹部受け部３８の先端部分に当接して摺動が停止する。 When the cap 40 is pushed further, the second engaging protrusion 44 bends and slides within the large diameter portion 38d. Then, the first engaging projection 43 formed on the collar portion 42 of the cap 40 comes into contact with the tip portion of the recess receiving portion 38 and stops sliding.

鍔部４２を回転させ、鍔部４２に形成された第１係合凸部４３を凹部受け部３８の先端部分に形成された先端溝部３８ａの位置に合わせると、第１係合凸部４３は、大径部３８ｄ内を更に摺動することが可能になる。そして、第２係合凸部４４が凹部受け部３８の大径部３８ｄに形成された内側溝部３８ｅに入り込むことによりキャップ４０が固定される。なお、予めキャップ４０の鍔部４２の第１係合凸部４３を凹部受け部３８の先端溝部３８ａの位置に合わせてキャップ４０を押し込めば、上記の鍔部４２の回転は不要である。 When the collar portion 42 is rotated to align the first engaging projection 43 formed on the collar portion 42 with the position of the tip groove portion 38a formed on the tip portion of the recess receiving portion 38, the first engaging projection portion 43 is , further slides in the large diameter portion 38d. Then, the cap 40 is fixed by the second engaging projection 44 entering the inner groove 38e formed in the large diameter portion 38d of the recess receiving portion 38. As shown in FIG. If the cap 40 is pushed in with the first engaging projection 43 of the flange 42 of the cap 40 aligned with the groove 38a of the recess receiving portion 38 in advance, the rotation of the flange 42 is unnecessary.

又、上記の第２係合凸部４４が第２胴部４１ｂ内を更に摺動するときには、キャップ４０の第３胴部４１ｃに形成されたシール部４５が凹部受け部３８の傾斜部３８ｃに当接、湾曲して撓んで、傾斜部３８ｃに弾接する。 Further, when the second engaging projection 44 slides further inside the second barrel portion 41b, the seal portion 45 formed on the third barrel portion 41c of the cap 40 contacts the inclined portion 38c of the recess receiving portion 38. It abuts, bends and bends, and elastically contacts the inclined portion 38c.

この結果、キャップ４０をボックス取付部２４の凹部２６内に挿入した時に、ボックス取付部２４の一方の側面２４ａに形成された円柱形状に突出した凸部２５をアーム部材収納部３７の凸部受け部３５の裏面側（アーム部材収納部３７の他の側面３７ｂ側）に押し、凸部２５と凸部受け部３５が接近又は当接する。そして、凸部２５と凸部受け部３５との間のクリアランスが小さくなる又は無くなるので、ボックス取付部２４がアーム部材収納部３７の凸部受け部３５内でがたつくことなく回動可能になる。 As a result, when the cap 40 is inserted into the concave portion 26 of the box mounting portion 24, the projection 25 formed on one side surface 24a of the box mounting portion 24 and projecting in a columnar shape receives the projection of the arm member housing portion 37. The rear surface side of the portion 35 (the other side surface 37b side of the arm member housing portion 37) is pushed, and the convex portion 25 and the convex portion receiving portion 35 approach or come into contact with each other. Since the clearance between the convex portion 25 and the convex portion receiving portion 35 is reduced or eliminated, the box attachment portion 24 can be rotated within the convex portion receiving portion 35 of the arm member housing portion 37 without rattling.

又、凹部受け部３８の先端溝部３８ａとキャップ４０の第１係合凸部４３が係合することにより、キャップ４０が凹部受け部３８に固定されるので、蓋１０の開閉に伴うアーム部材２０の回動によりキャップ４０が凹部受け部３８内で回動することを防止することができる。 In addition, since the cap 40 is fixed to the recess receiving portion 38 by engaging the tip groove portion 38a of the recess receiving portion 38 with the first engaging projection 43 of the cap 40, the arm member 20 can move when the lid 10 is opened and closed. It is possible to prevent the cap 40 from rotating within the recess receiving portion 38 due to the rotation of .

又、胴部４１の第２胴部４１ｂの側面に形成された第２係合凸部４４と凹部受け部３８の内側溝部３８eが係合するので、蓋１０の開閉や走行時の振動等によって、キャップ４０がアーム部材収納部３７の凹部受け部３８から抜けるのを防止することができる。 In addition, since the second engaging protrusion 44 formed on the side surface of the second body portion 41b of the body portion 41 and the inner groove portion 38e of the recess receiving portion 38 are engaged with each other, the opening and closing of the lid 10 and the vibration during running may cause the movement of the body. , the cap 40 can be prevented from slipping out of the recess receiving portion 38 of the arm member housing portion 37 .

更に、キャップ４０の第３胴部４１ｃに形成されたシール部４５が凹部受け部３８の傾斜部３８ｃに弾接するので、キャップ４０の鍔部４２と凹部受け部３８との間から水がボックス取付部２４側に侵入した場合も、ボックス取付部２４の凹部２６とキャップ４０の第１胴部４１ａとの間に水が浸入することを防止することができる。 Furthermore, since the seal portion 45 formed on the third body portion 41c of the cap 40 is in elastic contact with the inclined portion 38c of the recessed portion receiving portion 38, water is prevented from entering between the collar portion 42 of the cap 40 and the recessed portion receiving portion 38. Even when water enters the portion 24 side, it is possible to prevent water from entering between the concave portion 26 of the box mounting portion 24 and the first body portion 41 a of the cap 40 .

本発明の実施にあたっては、上記実施形態に限定されるものではなく、本発明の目的を逸脱しない限りにおいて、種々の変更が可能である。 The implementation of the present invention is not limited to the above embodiments, and various modifications are possible without departing from the object of the present invention.

例えば、上記の実施形態では、キャップ４０の第３胴部４１ｃに形成したシール部４５は、断面において先細り形状に形成したが、半円形状に形状してもよい。この場合は、半円形状のシール部４５の凹部受け部３８の傾斜部３８ｃとの当接面が少し潰れることにより、傾斜部３８ｃとの間をシールする。 For example, in the above embodiment, the seal portion 45 formed on the third body portion 41c of the cap 40 is tapered in cross section, but may be semicircular. In this case, the contact surface of the semi-circular seal portion 45 with the inclined portion 38c of the recess receiving portion 38 is slightly crushed, thereby sealing between the inclined portion 38c.

例えば、アーム部材収納部３７の凹部受け部３８とキャップ４０については、アーム部材収納部３７の凹部受け部３８に先端溝部３８ａを設けず、キャップ４０の鍔部４２の下部に第１係合凸部４３を形成せず、単にキャップ４０を凹部受け部３８に挿入することにより、キャップ４０の胴部４１をボックス取付部２４の凹部２６に嵌め込んでも良い。 For example, with respect to the recess receiving portion 38 of the arm member housing portion 37 and the cap 40, the recess receiving portion 38 of the arm member housing portion 37 is not provided with the tip groove portion 38a, and the first engagement projection is formed on the lower portion of the collar portion 42 of the cap 40. The body portion 41 of the cap 40 may be fitted into the recess 26 of the box mounting portion 24 by simply inserting the cap 40 into the recess receiving portion 38 without forming the portion 43 .

例えば、上記の実施形態では、アーム部材収納部３７の片側の側面（３７ｂ）にボックス取付部２４の凹部２６に合致する凹部受け部３８を形成し、ボックス取付部２４の片側の側面（２４ｂ）に凹部２６を形成したが、アーム部材収納部３７の両側の側面に凹部受け部３８を形成し、ボックス取付部２４の両側に凹部２６を形成し、両側からキャップ４０によってアーム部材収納部３７にボックス取付部２４を固定するようにしてもよい。 For example, in the above-described embodiment, the concave receiving portion 38 that matches the concave portion 26 of the box mounting portion 24 is formed on one side surface (37b) of the arm member housing portion 37, and one side surface (24b) of the box mounting portion 24 is formed. In addition, recess receiving portions 38 are formed on both side surfaces of the arm member housing portion 37, recesses 26 are formed on both sides of the box mounting portion 24, and the arm member housing portion 37 is covered with caps 40 from both sides. The box mounting portion 24 may be fixed.

例えば、上記の実施形態では、キャップ４０の第２胴部４１ｂの第２係合凸部４４は、凹部受け部３８の内側溝部３８ｅと同様に周状に形成したが、内側溝部３８ｅに合致すれば部分的、例えば、線状やドット状に形成してもよい。これによって、第２係合凸部４４が凹部受け部３８の大径部３８ｄ内で撓み易くなり、通過し易くなるからである。 For example, in the above-described embodiment, the second engaging projection 44 of the second barrel 41b of the cap 40 is formed in a circumferential shape similar to the inner groove 38e of the recess receiving portion 38. Alternatively, it may be formed partially, for example, in a line shape or a dot shape. This is because the second engaging projection 44 can easily bend within the large-diameter portion 38d of the recess receiving portion 38 and easily pass through.
