すなわち、図２で示すように、インナパネル３０及びアウタパネル４０には、ピボットシャフト１８を挿通させる円形の貫通孔３０Ａ、４０Ａがそれぞれ形成されている。そして、取付部材２０は、ピボットシャフト１８をインナパネル３０の貫通孔３０Ａ及びアウタパネル４０の貫通孔４０Ａに順に挿通させつつ、インナパネル３０の凹部３２（後述）内へ配置されるようになっている。   That is, as shown in FIG. 2, circular through holes 30 </ b> A and 40 </ b> A through which the pivot shaft 18 is inserted are formed in the inner panel 30 and the outer panel 40, respectively. And the attachment member 20 is arrange | positioned in the recessed part 32 (after-mentioned) of the inner panel 30, inserting the pivot shaft 18 through the through-hole 30A of the inner panel 30, and the through-hole 40A of the outer panel 40 in order. .

なお、アウタパネル４０の貫通孔４０Ａから外方側へ突出されたピボットシャフト１８の先端部には、リアワイパ装置１４のワイパアーム１９が取り付けられるようになっている。また、本発明に係る回動手段は、少なくともモーター１６とピボットシャフト１８とを含んで構成されている。   The wiper arm 19 of the rear wiper device 14 is attached to the tip of the pivot shaft 18 that protrudes outward from the through hole 40A of the outer panel 40. The rotating means according to the present invention includes at least the motor 16 and the pivot shaft 18.

図１〜図３、図８で示すように、取付部材２０は、正面視略二等辺三角形状に形成されており、その外周縁部には、補強用のフランジ部２２が車体後方側へ向かって延在するように一体に形成されている。そして、取付部材２０の複数（この場合は３つ）の角部は、それぞれ被締結孔としての円形のネジ孔２６Ａを有する正面視略三角形状の締結部２６とされている。各締結部２６は、正面視略六角形状の本体部２４と、その高さ（フランジ部２２の幅）が異なるように（段差ができるように）形成されている。   As shown in FIG. 1 to FIG. 3 and FIG. 8, the mounting member 20 is formed in a substantially isosceles triangle shape when viewed from the front, and a reinforcing flange portion 22 is provided at the outer peripheral edge of the mounting member 20 toward the rear side of the vehicle body. Are integrally formed so as to extend. A plurality of (in this case, three) corners of the attachment member 20 are fastening portions 26 each having a substantially triangular shape as viewed from the front, each having a circular screw hole 26A serving as a fastening hole. Each fastening portion 26 is formed so that the height (width of the flange portion 22) of the main body portion 24 having a substantially hexagonal shape when viewed from the front is different (so that there is a step).

すなわち、取付部材２０の各締結部２６は、本体部２４よりも高さが低く（フランジ部２２の幅が小さく）なるように、換言すれば、取付部材２０の本体部２４は、各締結部２６よりも高さが高く（フランジ部２２の幅が大きく）なるように形成されている。そして、その本体部２４の車体後方側を向く壁面とインナパネル３０の凹部３２における底面３４（後述）との間に、リアワイパ装置１４のモーター１６等が収容されるようになっている（図２参照）。   That is, each fastening portion 26 of the mounting member 20 is lower in height than the main body portion 24 (in other words, the width of the flange portion 22 is small), in other words, the main body portion 24 of the mounting member 20 is connected to each fastening portion. The height is higher than 26 (the width of the flange portion 22 is large). The motor 16 and the like of the rear wiper device 14 are accommodated between a wall surface facing the vehicle body rear side of the main body 24 and a bottom surface 34 (described later) of the recess 32 of the inner panel 30 (FIG. 2). reference).

また、この取付部材２０は、例えばアルミニウム等の金属で成形されている。そして、図２、図６、図７で示すように、各締結部２６のネジ孔２６Ａは、各締結部２６の略中央部に車体後方側に向かって一体に延設された円筒部２８の内周面に雌ネジを切ることで構成されている。   The mounting member 20 is formed of a metal such as aluminum. As shown in FIGS. 2, 6, and 7, the screw hole 26 </ b> A of each fastening portion 26 is formed on a substantially central portion of each fastening portion 26 of a cylindrical portion 28 that is integrally extended toward the rear side of the vehicle body. It is configured by cutting a female thread on the inner peripheral surface.

なお、この円筒部２８の高さ（長さ）は、締結部２６におけるフランジ部２２の幅（高さ）以下とされている。これにより、後述する凹部３２の底面３４と支持部３８との間に締結部２６を挿入させる際に、その底面３４を円筒部２８の先端で傷付けることがないようにできる構成である。   The height (length) of the cylindrical portion 28 is set to be equal to or less than the width (height) of the flange portion 22 in the fastening portion 26. Thereby, when inserting the fastening part 26 between the bottom face 34 of the recessed part 32 mentioned later and the support part 38, it is the structure which can prevent the bottom face 34 from being damaged by the front-end | tip of the cylindrical part 28. FIG.

一方、バックドア１２のインナパネル３０は、ポリカーボネート（ＰＣ）等の樹脂製とされている。そして、図１、図２で示すように、そのインナパネル３０の所定位置には、取付部材２０（モーター１６等）を収容するために、アウタパネル４０側へ突出するように凹んだ略矩形状の凹部（収容部）３２が形成されている。   On the other hand, the inner panel 30 of the back door 12 is made of resin such as polycarbonate (PC). As shown in FIGS. 1 and 2, the inner panel 30 has a substantially rectangular shape recessed at a predetermined position so as to protrude toward the outer panel 40 in order to accommodate the mounting member 20 (motor 16 or the like). A concave portion (accommodating portion) 32 is formed.

また、その凹部３２の内周縁部３３における所定間隔を隔てた複数（この場合は３つ）の位置、即ち取付部材２０の各締結部２６に対応した上部側の両端位置と下部側の中央位置には、被取付部３６がそれぞれ一体に突設されている。   Further, a plurality of (in this case, three) positions at a predetermined interval in the inner peripheral edge 33 of the recess 32, that is, both upper end positions and lower center positions corresponding to the respective fastening portions 26 of the mounting member 20. Each of the attached portions 36 is integrally projected.

各被取付部３６は、図３〜図８で示すように、凹部３２の内周縁部３３の上部側両端位置と下部側中央位置にそれぞれ連設された正面視略矩形状（略矩形平板状）の連設部３７と、その連設部３７の突出方向（延在方向）先端に一体に連設された正面視略円形状（略円板状）の支持部３８とを有している。   As shown in FIGS. 3 to 8, each attached portion 36 has a substantially rectangular shape (substantially rectangular flat plate shape) as viewed from the front, which is connected to both the upper end positions and the lower center position of the inner peripheral edge 33 of the recess 32. ) And a support portion 38 having a substantially circular shape (substantially disk shape) in front view, which is integrally provided at the tip of the protruding direction (extending direction) of the continuous portion 37. .

そして、その支持部３８の中央部には、後述する段付きボルト４２の段部４３を挿通させるための円形の貫通孔３８Ａが形成されている。つまり、この貫通孔３８Ａの内径は、段付きボルト４２の段部４３を遊挿可能に、その段部４３の外径よりも若干大きく形成されている。   A circular through hole 38 </ b> A for inserting a stepped portion 43 of a stepped bolt 42 described later is formed at the center of the support portion 38. That is, the inner diameter of the through hole 38A is slightly larger than the outer diameter of the stepped portion 43 so that the stepped portion 43 of the stepped bolt 42 can be loosely inserted.

また、各被取付部３６は、図８で示すように、連設部３７が取付部材２０の中心（内心）に向かって延在するように、かつ、支持部３８が凹部３２の底面（一般面）３４から少なくとも締結部２６の高さ（締結部２６におけるフランジ部２２の幅）分は車室Ｓ（図２参照）側へ離隔した位置に存在するように、凹部３２の内周縁部３３の所定位置に突設されている。   Further, as shown in FIG. 8, each attached portion 36 has a continuous portion 37 extending toward the center (inner center) of the attachment member 20, and a support portion 38 having a bottom surface (general) The inner peripheral edge portion 33 of the recess 32 so that at least the height of the fastening portion 26 (the width of the flange portion 22 in the fastening portion 26) is located away from the vehicle surface S (see FIG. 2). Projecting at a predetermined position.

そして、凹部３２の底面３４には、その被取付部３６（連設部３７及び支持部３８）がアンダーカットにならないように（インナパネル３０が金型から取り出せるように）成形したために、被取付部３６と正面視で同形状の孔部３４Ａが形成されている（図４参照）。したがって、例えば段付きボルト４２のネジ部４４（図６、図７参照）の長さが円筒部２８の長さ以上になっていても、その段付きボルト４２でネジ止めできる構成である。なお、図示の段付きボルト４２のネジ部４４の長さは、円筒部２８の長さと略同一とされている。   And since the to-be-attached part 36 (continuous connection part 37 and the support part 38) was shape | molded in the bottom face 34 of the recessed part 32 so that an undercut might not be carried out (inner panel 30 can be taken out from a metal mold | die), A hole 34A having the same shape as that of the portion 36 is seen from the front (see FIG. 4). Therefore, for example, even if the length of the threaded portion 44 (see FIGS. 6 and 7) of the stepped bolt 42 is longer than the length of the cylindrical portion 28, the stepped bolt 42 can be screwed. The length of the threaded portion 44 of the illustrated stepped bolt 42 is substantially the same as the length of the cylindrical portion 28.

また、各被取付部３６（連設部３７及び支持部３８）の外周縁部には、車体前方側へ向かって突出（延在）する補強用のリブ（補強手段）３９が一体に形成されており、各連設部３７及び各支持部３８の強度が高められるようになっている。そして更に、各連設部３７の外周縁部には、車体後方側へ向かって突出する補強用のリブ３９Ａが、リブ３９と一体に形成されており、連設部３７の強度がより一層高められるようになっている。   In addition, reinforcing ribs (reinforcing means) 39 that protrude (extend) toward the front side of the vehicle body are integrally formed at the outer peripheral edge of each attached portion 36 (the continuous portion 37 and the support portion 38). In addition, the strength of each connecting portion 37 and each supporting portion 38 can be increased. Furthermore, reinforcing ribs 39A that protrude toward the rear side of the vehicle body are formed integrally with the ribs 39 on the outer peripheral edge of each connecting portion 37, and the strength of the connecting portions 37 is further increased. It is supposed to be.

なお、各連設部３７の外周縁部に形成するリブ３９、３９Ａは、凹部３２の内周縁部３３との連設部位が最も高くなるように、支持部３８側から内周縁部３３側にかけて徐々にその高さが高くなるような傾斜状に形成されている。これにより、各連設部３７の強度を更に向上できる構成である。   It should be noted that the ribs 39 and 39A formed on the outer peripheral edge portion of each connecting portion 37 extend from the support portion 38 side to the inner peripheral edge portion 33 side so that the connecting portion with the inner peripheral edge portion 33 of the recess 32 is the highest. It is formed in an inclined shape so that its height gradually increases. Thereby, it is the structure which can improve the intensity | strength of each connection part 37 further.

次に、このような被取付部３６に取付部材２０を取り付ける取付工程（取付構造１０）について説明する。図１〜図３で示すように、貫通孔３０Ａ、４０Ａにピボットシャフト１８を挿通しつつ、モーター１６等が取り付けられた取付部材２０をインナパネル３０の凹部３２内に配置する。このとき、まず、図３（Ａ）で示すように、各被取付部３６に各締結部２６が干渉しないように、取付部材２０を傾けた（ピボットシャフト１８を中心に回転させた）状態で支持する。   Next, an attachment process (attachment structure 10) for attaching the attachment member 20 to the attached portion 36 will be described. As shown in FIGS. 1 to 3, the attachment member 20 to which the motor 16 and the like are attached is disposed in the recess 32 of the inner panel 30 while the pivot shaft 18 is inserted into the through holes 30 </ b> A and 40 </ b> A. At this time, first, as shown in FIG. 3A, the attachment member 20 is tilted (rotated around the pivot shaft 18) so that each fastening portion 26 does not interfere with each attached portion 36. To support.

次いで、その取付部材２０を支持したまま、例えば図３、図４で示す矢印Ｒ方向に、ピボットシャフト１８を中心に取付部材２０を回転させ、各締結部２６を各被取付部３６のボルト挿通方向下流側、即ち凹部３２の底面３４（孔部３４Ａ）と各被取付部３６の支持部３８との間に挿入させる。そして、貫通孔３８Ａとネジ孔２６Ａとを連通させる（図５参照）。   Next, with the mounting member 20 being supported, the mounting member 20 is rotated around the pivot shaft 18 in the direction of the arrow R shown in FIGS. 3 and 4, for example, and each fastening portion 26 is inserted through the bolt of each mounted portion 36. It is inserted in the direction downstream side, that is, between the bottom surface 34 (hole 34A) of the recess 32 and the support portion 38 of each attached portion 36. Then, the through hole 38A and the screw hole 26A are communicated (see FIG. 5).

その後、図１、図２、図３（Ｂ）で示すように、締結具としての段付きボルト４２のネジ部４４を各被取付部３６の支持部３８に形成されている貫通孔３８Ａ（車室Ｓ側）から挿通して各締結部２６のネジ孔２６Ａに螺合する（ネジ止めして締結する）。これにより、取付部材２０が各被取付部３６に取り付けられる。   Thereafter, as shown in FIGS. 1, 2, and 3 (B), the screw portions 44 of the stepped bolts 42 as fasteners are formed in the through holes 38 </ b> A (vehicles) formed in the support portions 38 of the attached portions 36. Inserted from the chamber S side) and screwed into the screw holes 26A of the respective fastening portions 26 (fastened with screws). Thereby, the attachment member 20 is attached to each attached part 36.

なお、締結具としては、段付きボルト４２を使用することが望ましい。すなわち、段付きボルト４２の段部４３を貫通孔３８Ａに遊挿させ、段付きボルト４２のフランジ部４５（図６、図７参照）と取付部材２０（締結部２６）とで樹脂製の被取付部３６を押さえるような構成とすることが望ましい。これによれば、締結時の軸力確保のために必要とされる金属カラー等を省略することができる。   In addition, it is desirable to use the stepped bolt 42 as a fastener. That is, the step 43 of the stepped bolt 42 is loosely inserted into the through hole 38A, and the flange portion 45 (see FIGS. 6 and 7) of the stepped bolt 42 and the mounting member 20 (fastening portion 26) are made of resin. It is desirable that the mounting portion 36 be pressed. According to this, the metal collar etc. which are required for securing the axial force at the time of fastening can be omitted.

以上のようなリアワイパ装置１４の取付構造１０において、次にその作用について説明する。上記したように、樹脂製のインナパネル３０に一体に設けられた被取付部３６に、リアワイパ装置１４のモーター１６等が取り付けられた取付部材２０が取り付けられる（締結される）。   Next, the operation of the mounting structure 10 for the rear wiper device 14 will be described. As described above, the attachment member 20 to which the motor 16 and the like of the rear wiper device 14 are attached is attached (fastened) to the attachment portion 36 provided integrally with the resin inner panel 30.

すなわち、各被取付部３６の支持部３８と凹部３２の底面３４との間に取付部材２０の各締結部２６が挿入される。そして、各被取付部３６の支持部３８に形成されている貫通孔３８Ａ（車室Ｓ側）から段付きボルト４２のネジ部４４がそれぞれ挿通されて、各締結部２６に形成されたネジ孔２６Ａに直接螺合される（ネジ止めされる）。   That is, each fastening portion 26 of the attachment member 20 is inserted between the support portion 38 of each attached portion 36 and the bottom surface 34 of the recess 32. And the screw part 44 of the stepped bolt 42 is each inserted from the through-hole 38A (vehicle compartment S side) formed in the support part 38 of each to-be-attached part 36, and the screw hole formed in each fastening part 26 26A is directly screwed (screwed).

したがって、従来必要とされていたナットが不要となり、アウタパネル４０に対向するインナパネル３０の外壁面に、そのナットを予め固着する工程が不要となる。つまり、この取付構造１０によれば、部品点数及び組立工数を低減させることができる。また、被取付部３６及び締結部２６は、所定間隔を隔てて複数（３組）設けられているので、インナパネル３０が樹脂製とされていても、金属製の取付部材２０を被取付部３６に安定した状態で取り付けることができる。   Therefore, a nut that has been conventionally required is not required, and a process of previously fixing the nut to the outer wall surface of the inner panel 30 facing the outer panel 40 is not required. That is, according to this mounting structure 10, the number of parts and the number of assembly steps can be reduced. Moreover, since the to-be-attached part 36 and the fastening part 26 are provided with multiple (three sets) at predetermined intervals, even if the inner panel 30 is made of resin, the metal attachment member 20 is attached to the attached part. 36 can be attached in a stable state.

また、各被取付部３６（連設部３７及び支持部３８）が樹脂製であり、かつ図８で示すように、連設部３７の突出方向（延在方向）が、ワイパアーム１９の回動によって、その連設部３７に作用する力の方向Ｆ１、Ｆ２と略直交する方向になっている。したがって、ワイパアーム１９が回動したときに、取付部材２０及び支持部３８を介して、各被取付部３６の連設部３７が、矢印Ｆ１方向又は矢印Ｆ２方向へ撓むことができる。つまり、このような構成によれば、ワイパアーム１９の回動時の反転による反動を各被取付部３６の連設部３７によって吸収することができ、反動緩和のために必要とされていたゴムブッシュ等を省略することができる。   Further, each attached portion 36 (continuous portion 37 and support portion 38) is made of resin, and as shown in FIG. 8, the protruding direction (extending direction) of the continuous portion 37 is the rotation of the wiper arm 19. Therefore, the direction of the force acting on the connecting portion 37 is substantially perpendicular to the directions F1 and F2. Therefore, when the wiper arm 19 rotates, the connecting portion 37 of each attached portion 36 can be bent in the direction of the arrow F1 or the arrow F2 via the attachment member 20 and the support portion 38. In other words, according to such a configuration, the reaction caused by the reversal of the wiper arm 19 during the rotation can be absorbed by the connecting portion 37 of each attached portion 36, and the rubber bush required for mitigating the reaction. Etc. can be omitted.

しかも、各被取付部３６（連設部３７及び支持部３８）の外周縁部、特に連設部３７の外周縁部には、補強用のリブ３９、３９Ａが一体に形成され、更にそのリブ３９、３９Ａは、凹部３２の内周縁部３３側の高さが支持部３８側の高さよりも高くなるように形成されているので、被取付部３６（特に連設部３７）の強度は充分に確保されている。したがって、ワイパアーム１９の回動時の反転による反動を各被取付部３６の連設部３７で確実に吸収することができ、連設部３７が折損するような不具合が起きることがない。   Moreover, reinforcing ribs 39 and 39A are integrally formed on the outer peripheral edge portion of each attached portion 36 (continuous portion 37 and support portion 38), particularly on the outer peripheral edge portion of the continuous portion 37, and the ribs are further formed. 39 and 39A are formed such that the height on the inner peripheral edge 33 side of the recess 32 is higher than the height on the support portion 38 side, and therefore the strength of the attached portion 36 (particularly the connecting portion 37) is sufficient. Is secured. Therefore, the reaction caused by the reversal of the wiper arm 19 during the rotation can be reliably absorbed by the connecting portions 37 of the attached portions 36, and there is no problem that the connecting portions 37 are broken.

また、この取付部材２０は、段付きボルト（締結具）４２のネジ部４４の挿通方向下流側が自動車の外方側であるため、即ち締結部２６が被取付部３６の支持部３８と凹部３２の底面３４との間に挿入され、車室Ｓ側から段付きボルト４２によって被取付部３６に取り付けられる構造であるため、取付部材２０の被取付部３６に対する取付作業が容易にできるメリットもある。   In addition, the mounting member 20 has a stepped bolt (fastener) 42 on the downstream side in the insertion direction of the threaded portion 44, that is, the outer side of the automobile, that is, the fastening portion 26 has the support portion 38 and the recessed portion 32 of the attached portion 36. Since the structure is inserted between the bottom surface 34 and the mounting portion 36 by the stepped bolts 42 from the compartment S side, there is an advantage that the mounting work of the mounting member 20 to the mounting portion 36 can be facilitated. .

以上、本実施形態に係るリアワイパ装置１４の取付構造１０について説明したが、本実施形態に係る取付構造１０は、図示の実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において、適宜設計変更可能なものである。例えば、被取付部３６の数量が変更されれば、それに応じて、取付部材２０の形状（締結部２６の数量）が変更される。したがって、取付部材２０の形状は、図示の二等辺三角形状に限定されるものではない。   The mounting structure 10 for the rear wiper device 14 according to the present embodiment has been described above. However, the mounting structure 10 according to the present embodiment is not limited to the illustrated embodiment, and does not depart from the gist of the present invention. The design can be changed as appropriate. For example, if the quantity of the attachment part 36 is changed, the shape of the attachment member 20 (the quantity of the fastening part 26) will be changed accordingly. Therefore, the shape of the attachment member 20 is not limited to the illustrated isosceles triangle shape.
