In other words, the fixing member 27 is arranged such that the tip end opening portion (the upper end opening portion in FIG. 3) of the cylindrical portion 42b is on a plane orthogonal to the rotation axis M2 of the worm wheel 23 shown in FIG. Further, such a fixing member 27 is disposed such that the central axis M1 of the cylindrical portion 42b is inclined with respect to the vertical direction of the plane of the control circuit board 25 (see FIG. 3).

上記のように構成された電動駆動装置１は、車両ドアのインナパネル５１（図４参照）と図示しないアウタパネルの間で、インナパネル５１（図４参照）に対して固定される。詳しくは、インナパネル５１には、インナパネル側挿入孔５１ａが形成され、そのインナパネル側挿入孔５１ａに筒状シール部材４２の筒状部４２ｂの先端が内嵌され、且つインナパネル側挿入孔５１ａの周囲に密着フランジ部４２ｃが密着するように、電動駆動装置１が図示しないボルト等により固定される。尚、電動駆動装置１は、前記回転軸６ａの軸線方向から見た前記ホイール収容部２１ｃの扁平軸線Ｌ２（扁平面２１ｅ）がインナパネル５１と平行となるように固定される。 The electric drive device 1 configured as described above is fixed to the inner panel 51 (see FIG. 4) between the inner panel 51 (see FIG. 4) of the vehicle door and the outer panel (not shown). Specifically, the inner panel 51 has an inner panel side insertion hole 51a formed therein, the tip of the cylindrical portion 42b of the cylindrical seal member 42 is fitted into the inner panel side insertion hole 51a, and the inner panel side insertion hole The electric drive device 1 is fixed by a bolt or the like (not shown) so that the contact flange portion 42c is in close contact with the periphery of 51a. The electric drive device 1 is fixed so that the flat axis L2 (flat surface 21e) of the wheel accommodating portion 21c viewed from the axial direction of the rotating shaft 6a is parallel to the inner panel 51.

そして、インナパネル５１の裏側（即ち、反アウタパネル側であってドアトリム側）から外部コネクタ５０（図４参照）が、インナパネル側挿入孔５１ａを通って端子支持部材３４のコネクタ凹部３４ａと外部コネクタ支持部材３８とで形成される雌コネクタに嵌着される。これにより、外部コネクタ５０に設けられた外部端子５０ａが前記外部用端子３３に電気的に接続される。尚、外部端子５０ａは、図示しない制御装置（電源装置）に接続されている。又、前記出力軸２８は、図５に示すように、その軸直交方向に配置されるレギュレータ（セクタギヤ）５２に駆動連結され、該レギュレータ５２等を介して車両ウインドウガラスに駆動連結される。 Then, the external connector 50 (see FIG. 4) from the back side of the inner panel 51 (that is, the anti-outer panel side and the door trim side) passes through the inner panel side insertion hole 51a and the connector recess 34a of the terminal support member 34 and the external connector. A female connector formed with the support member 38 is fitted. As a result, the external terminal 50 a provided on the external connector 50 is electrically connected to the external terminal 33. The external terminal 50a is connected to a control device (power supply device) (not shown).

次に、上記実施の形態の特徴的な作用効果を以下に記載する。
（１）制御回路基板２５は、回転軸６ａの軸線方向から見たその扁平軸線Ｌ３がホイール収容部２１ｃの扁平軸線Ｌ２に対して傾斜するように配置される。よって、本実施の形態のように、制御回路基板２５上のホール素子３２を回転軸６ａのセンサ用マグネット６ｂと（前記扁平軸線Ｌ３の直交方向に）対向するように配置させる場合でも、制御回路基板２５を、他の何らかの部材を容易に避けながら配置することができる。言い換えると、制御回路基板２５は、前記扁平軸線Ｌ３が前記扁平軸線Ｌ２に対して平行となるように配置しようとすると、制御回路基板２５上のホール素子３２をセンサ用マグネット６ｂと（前記扁平軸線Ｌ３の直交方向に）対向するように配置させる場合等、他の何らかの部材が邪魔で容易に配置できない虞があるが、これを回避することができる。尚、前記他の何らかの部材とは、例えば、回転軸６ａの軸方向から見たヨーク４（モータ本体２）の四隅をハウジング本体２１に固定するためのネジ機構（雄ネジ及び雌ネジ）や、ハウジング本体２１に埋設される何らかのターミナル等、種々の部材である。 Next, characteristic effects of the above embodiment will be described below.
(1) The control circuit board 25 is disposed such that the flat axis L3 viewed from the axial direction of the rotating shaft 6a is inclined with respect to the flat axis L2 of the wheel accommodating portion 21c. Therefore, even when the Hall element 32 on the control circuit board 25 is arranged to face the sensor magnet 6b of the rotating shaft 6a (in the direction orthogonal to the flat axis L3) as in the present embodiment, the control circuit The board | substrate 25 can be arrange | positioned, avoiding some other member easily. In other words, when the control circuit board 25 is arranged so that the flat axis L3 is parallel to the flat axis L2, the Hall element 32 on the control circuit board 25 is connected to the sensor magnet 6b (the flat axis line). There is a possibility that some other member cannot be easily disposed due to obstruction, for example, when it is disposed so as to face each other (in the orthogonal direction of L3), but this can be avoided. The other members include, for example, screw mechanisms (male screws and female screws) for fixing the four corners of the yoke 4 (motor body 2) viewed from the axial direction of the rotating shaft 6a to the housing body 21, Various members such as any terminal embedded in the housing main body 21.

しかも、制御回路基板２５の外部用端子３３及び基板収容部２１ｄの開口部２１ｈは、回転軸６ａの軸線方向から見た制御回路基板２５の扁平軸線Ｌ３の直交方向から開口部２１ｈを通して外部用端子３３に外部コネクタ５０の外部端子５０ａが接続可能となるように設定されるため、上記効果を得ながら、外部からの電気的な接続が容易となる。 Moreover, the external terminal 33 of the control circuit board 25 and the opening 21h of the board housing part 21d are external terminals through the opening 21h from the direction orthogonal to the flat axis L3 of the control circuit board 25 when viewed from the axial direction of the rotating shaft 6a. Since the external terminal 50a of the external connector 50 is set to be connectable to the external connector 50, electrical connection from the outside is facilitated while obtaining the above effects.

（２）ハウジング本体２１には、開口部２１ｈの内周とインナパネル５１に形成されたインナパネル側挿入孔５１ａとの間をシールするための筒状シール部材４２が設けられるため、インナパネル側挿入孔５１ａを通して外部用端子３３に接続した状態の外部コネクタ５０を筒状シール部材４２で覆うことができる。その結果、例えば、インナパネル５１とアウタパネルとの間に、雨水等の液体が浸入しても外部コネクタ５０等の電気的接続部分が被水することが防止される。 (2) Since the housing main body 21 is provided with a cylindrical sealing member 42 for sealing between the inner periphery of the opening 21h and the inner panel side insertion hole 51a formed in the inner panel 51, the inner panel side The external connector 50 connected to the external terminal 33 through the insertion hole 51 a can be covered with the cylindrical seal member 42. As a result, for example, even if a liquid such as rainwater enters between the inner panel 51 and the outer panel, the electrical connection portion such as the external connector 50 is prevented from getting wet.

（３）基板収容部２１ｄは、回転軸６ａ（ウォーム収容部２１ｂ）を中心としてホイール収容部２１ｃの反対側に形成されるため、回転軸６ａ（ウォーム収容部２１ｂ）を中心とした形状のバランスが良好となる（一方側が極端に大型化しない）。 (3) Since the substrate housing portion 21d is formed on the opposite side of the wheel housing portion 21c with the rotating shaft 6a (worm housing portion 21b) as the center, the balance of the shape with the rotating shaft 6a (worm housing portion 21b) as the center (The one side does not become extremely large).

（４）制御回路基板２５は、その扁平軸線Ｌ３（平面）が基板収容部２１ｄの扁平軸線Ｌ１と平行となるように配置される。言い換えると、本実施の形態の基板収容部２１ｄは、回転軸６ａの軸線方向から見て制御回路基板２５（その扁平面）に沿って形成されている。このようにすると、前述したように傾斜した制御回路基板２５に対して基板収容部２１ｄの余計な収容スペースを小さくすることができ、基板収容部２１ｄの均等な薄型化、ひいては電動駆動装置１の小型化を図ることができる。また、例えば、基板収容部２１ｄが、電動駆動装置１の出力軸２８に駆動連結されるレギュレータ（セクタギヤ）５２と干渉（衝突）することを容易に回避することができる。 (4) The control circuit board 25 is arranged such that its flat axis L3 (plane) is parallel to the flat axis L1 of the board housing portion 21d. In other words, the substrate accommodating portion 21d of the present embodiment is formed along the control circuit substrate 25 (its flat surface) when viewed from the axial direction of the rotating shaft 6a. In this way, it is possible to reduce the extra storage space of the board housing portion 21d with respect to the control circuit board 25 inclined as described above, and to make the board housing portion 21d evenly thinner, and consequently the electric drive device 1 Miniaturization can be achieved. Further, for example, it is possible to easily avoid the substrate housing portion 21d from interfering with (collising with) the regulator (sector gear) 52 that is drivingly connected to the output shaft 28 of the electric drive device 1.

上記実施の形態は、以下のように変更してもよい。
・上記実施の形態では、ハウジング本体２１には、開口部２１ｈの内周とインナパネル５１に形成されたインナパネル側挿入孔５１ａとの間をシールするための筒状シール部材４２が設けられるとしたが、これに限定されず、筒状シール部材４２（固定部材２７）が設けられていない電動駆動装置としてもよい。例えば、開口部２１ｈとインナパネル側挿入孔５１ａとの間をシールするためのシール部材を、インナパネル５１に（筒状シール部材４２を備えていない）電動駆動装置を固定する際に同時に固定するように変更してもよい。尚、勿論、上記実施の形態の筒状シール部材４２は、開口部２１ｈとインナパネル側挿入孔５１ａとの間をシールできれば、他の構成（例えば、内嵌部材４１以外の構成で固定されるもの等）に変更してもよい。 The above embodiment may be modified as follows.
In the above embodiment, the housing main body 21 is provided with the cylindrical seal member 42 for sealing between the inner periphery of the opening 21 h and the inner panel side insertion hole 51 a formed in the inner panel 51. However, it is not limited to this, It is good also as an electric drive device in which the cylindrical seal member 42 (fixing member 27) is not provided. For example, a sealing member for sealing between the opening 21h and the inner panel side insertion hole 51a is fixed at the same time when the electric drive device (without the cylindrical sealing member 42) is fixed to the inner panel 51. It may be changed as follows. Of course, the cylindrical seal member 42 of the above embodiment is fixed in another configuration (for example, a configuration other than the internal fitting member 41) as long as the space between the opening 21h and the inner panel side insertion hole 51a can be sealed. You may change it to a thing etc.).

・上記実施の形態では、基板収容部２１ｄは、回転軸６ａ（ウォーム収容部２１ｂ）を中心としてホイール収容部２１ｃの反対側に形成されるとしたが、これに限定されず、基板収容部及びホイール収容部を、回転軸６ａ（ウォーム収容部２１ｂ）を中心として同じ側に形成してもよい。 In the above embodiment, the substrate housing portion 21d is formed on the opposite side of the wheel housing portion 21c with the rotation shaft 6a (worm housing portion 21b) as a center. You may form a wheel accommodating part in the same side centering on the rotating shaft 6a (worm | warm accommodating part 21b).

・上記実施の形態では、基板収容部２１ｄは、回転軸６ａの軸線方向から見て制御回路基板２５（その扁平面）に沿って形成される（扁平軸線Ｌ１と扁平軸線Ｌ３が平行）としたが、これに限定されず、基板収容部を制御回路基板２５に対して傾斜するように（扁平軸線Ｌ１と扁平軸線Ｌ３が非平行となるように）形成してもよい。例えば、基板収容部２１ｄの扁平軸線Ｌ３がホイール収容部２１ｃの扁平軸線Ｌ２と平行となるように形成してもよい。 In the above embodiment, the substrate housing portion 21d is formed along the control circuit substrate 25 (its flat surface) when viewed from the axial direction of the rotating shaft 6a (the flat axis L1 and the flat axis L3 are parallel). However, the present invention is not limited to this, and the substrate housing portion may be formed to be inclined with respect to the control circuit board 25 (so that the flat axis L1 and the flat axis L3 are not parallel). For example, you may form so that the flat axis L3 of the board | substrate accommodating part 21d may become in parallel with the flat axis L2 of the wheel accommodating part 21c.

・上記実施の形態では、基板収容部２１ｄの扁平軸線Ｌ１及び制御回路基板２５の扁平軸線Ｌ３がホイール収容部２１ｃの扁平軸線Ｌ２に対して３度傾斜される構成としたが、それら傾斜角度は適宜変更してもよく、特に限定されない。 In the above embodiment, the flat axis L1 of the board housing part 21d and the flat axis L3 of the control circuit board 25 are tilted by 3 degrees with respect to the flat axis L2 of the wheel housing part 21c. It may be changed as appropriate and is not particularly limited.

・上記実施の形態では、インナパネル５１とアウタパネルの間に配置されるパワーウインドウ装置の電動駆動装置１に具体化したが、これに限定されず、他の装置用の電動駆動装置に具体化してもよい。又、勿論、制御回路基板に備えられる電気回路部品（挟み込み防止回路）を装置等に応じて変更してもよい。 In the above embodiment, the electric drive device 1 of the power window device arranged between the inner panel 51 and the outer panel is embodied, but the invention is not limited to this, and the electric drive device for other devices is embodied. Also good. Of course, the electric circuit components (pinching prevention circuit) provided on the control circuit board may be changed according to the device or the like.
