As shown in FIG. On the other hand, the end portion 70B is positioned so as not to overlap with the control board 62 when viewed in the Z direction, and can be said to be positioned so as not to overlap with the casing 10 . That is, the electronic board 70 is directed outward in the radial direction when the drive shaft 32 is the central axis (the central axis of the motor 16 along the Z direction) from a position overlapping the control board 62 and the casing 10 . It extends to a position that does not overlap with 10.

電子基板70は、接続部材90を介して制御基板62に電気的に接続されており、コネクタ部80にも電気的に接続される。具体的には、電子基板70は、Z方向から見てケーシング10と重なる箇所において、接続部材90に接続される。電子基板70は、端部70Aが接続部材90に接続されてもよいし、端部70Aと端部70Bとの間の箇所が接続部材90に接続されてもよい。また、電子基板70は、Z方向から見てケーシング10と重ならない箇所において、コネクタ部80に接続されている。電子基板70は、端部70Bがコネクタ部80に接続されてもよいし、端部70Aと端部70Bとの間の箇所がコネクタ部80に接続されてもよい。 The electronic board 70 is electrically connected to the control board 62 via the connection member 90 and is also electrically connected to the connector section 80 .

The current-conducting portion 72A and the signal-conducting portion 72B can be said to be wiring that conducts current, and are sheet-like wiring patterns in this embodiment. Further, in the present embodiment, the area of the current conducting portion 72A is larger than the area of the signal conducting portion 72B. Although this allows the drive current to be conducted appropriately, the size relationship between the current conducting portion 72A and the signal conducting portion 72B is not limited to this and may be arbitrary. Note that the area here may be the area of the cross section of the current conducting portion 72A and the signal conducting portion 72B perpendicular to the direction in which the current flows. It may be called the area of the current conduction portion 72A and the signal conduction portion 72B.

本実施形態では、電子基板70は、複数の層が積層されて構成されており、言い換えれば、複数層の電流導通部72Aを有している。電子基板70は、複数の層構成となることで、電流導通部72Aの面積を確保して、駆動電流を適切に流すことができる。また、図2に示すように、電子基板70は、各層にわたって貫通する、複数の接続穴CH1と複数の接続穴CH2と複数の接続穴CH3とが形成されている。接続穴CH1は、端部70B側に、すなわち、Z方向から見た場合に制御基板62(ケーシング10)と重ならない位置に形成されている。接続穴CH1には、後述するコネクタ部80の端子部82が挿入される。接続穴CH2は、端部70A側に、すなわち、Z方向から見た場合に制御基板62(ケーシング10)と重なる位置に形成されている。接続穴CH2には、後述する接続部材90の電流接続部92が挿入される。接続穴CH3は、端部70A側に、すなわち、Z方向から見た場合に制御基板62(ケーシング10)と重なる位置に形成されている。接続穴CH3には、後述する接続部材90の信号接続部94が挿入される。 In this embodiment, the electronic substrate 70 is configured by laminating a plurality of layers, in other words, it has a plurality of layers of current conducting portions 72A. Since the electronic substrate 70 has a multi-layer structure, the area of the current conduction portion 72A can be secured and the drive current can be appropriately passed. Further, as shown in FIG. 2, the electronic board 70 is formed with a plurality of connection holes CH1, a plurality of connection holes CH2, and a plurality of connection holes CH3 penetrating through each layer. The connection hole CH1 is formed on the end portion 70B side, that is, at a position that does not overlap the control board 62 (casing 10) when viewed from the Z direction.

As shown in FIG. Hereinafter, the area where the electronic substrate 70 is provided in the surface 100A, that is, the area overlapping the electronic substrate 70 when viewed from the Z direction is referred to as an area AR1.

The first bonding area 101 is formed from a position overlapping the casing 10 when viewed from the Z direction of the surface 100A to a position not overlapping the casing 10 when viewed from the Z direction. Although the first adhesive region 101 is groove-shaped in this embodiment, it is not limited to this. They may be formed on the same plane.

なお、第1接着領域101よりも内側の領域は、領域AR1よりも広くなっている。すなわち、第1接着領域101の内周よりも内側の領域は、電子基板70と重なる領域AR1と、電子基板70と重ならない領域AR2とを含むといえる。第1接着領域101よりも内側の領域とは、Z方向から見て第1接着領域101に囲われる領域を指し、言い換えれば、第1接着領域101の中心を通るZ方向に沿った軸を軸方向とした場合に、第1接着領域101の内周よりも径方向内側の領域を指す。 A region inside the first adhesion region 101 is wider than the region AR1. That is, it can be said that the region inside the inner circumference of the first bonding region 101 includes the region AR1 overlapping with the electronic substrate 70 and the region AR2 not overlapping with the electronic substrate 70 . The region inside the first bonding region 101 refers to a region surrounded by the first bonding region 101 when viewed from the Z direction.

Furthermore, the opening 102 is formed at a position overlapping the connection member 90 and the connection holes CH2 and CH3 of the electronic substrate 70 when viewed from the Z direction. The connecting member 90 is positioned within the opening 102 and is connected to the electronic board 70 and the control board 62 through the opening 102 . Since the opening 102 is formed in the area AR, the Z1 direction side is covered with the electronic substrate 70 .

The depression 104 is a depression formed in the surface 100A of the support member 100 and recessed toward the surface 100B, and does not penetrate to the surface 100B. The recess 104 is formed inside the first bonding area 101 and at a position not overlapping the casing 10 (control board 62) when viewed in the Z direction. Recess 104 is formed from area AR1 to area AR2. Note that the recess 104 is not an essential component and may not be formed.

The opening 105 is formed in the area AR1, and is formed at a position where it does not overlap the casing 10 (control board 62) when viewed from the Z direction in the area AR1. Furthermore, the opening 105 is formed at a position overlapping the terminal portion 82 of the connector portion 80 and the connection hole CH1 of the electronic substrate 70 when viewed from the Z direction. The terminal portion 82 is positioned within the opening portion 105 and is connected to the electronic substrate 70 through the opening portion 105 . The opening 105 is covered with the electronic substrate 70 on the Z1 direction side.

The hole portion 106 is an opening into which a press-fitting portion 120 of the cover member 110, which will be described later, is press-fitted. In this embodiment, the hole 106 penetrates from the surface 100A of the support member 100 to the surface 100B. Since the hole 106 can be processed from the surface 100B by penetrating the hole 106 to the surface 100B, the labor for processing can be suppressed. However, the holes 106 are not limited to penetrating to the surface 100B.

固定部116のZ2方向側の表面116Aには、第2接着領域118が形成される。第2接着領域118は、支持部材100の第1接着領域101に接着される領域である。第2接着領域118は、カバー部112の外縁の全区間にわたって周状に形成されている。第2接着領域118は、支持部材100に取り付けられた際に、第1接着領域101と対向する位置に設けられる。本実施形態では、第2接着領域118は、表面116AからZ2方向側に突出する凸形状であるが、それに限られず、例えば表面116AからZ1方向側に窪む溝形状であってもよいし、表面100Aから窪んだり突出したりせずに、表面116Aと同一面に形成されてもよい。 A second adhesion region 118 is formed on the surface 116A of the fixed portion 116 on the Z2 direction side. The second adhesive area 118 is an area that is attached to the first adhesive area 101 of the support member 100 . The second adhesive region 118 is formed in a circumferential shape over the entire outer edge of the cover portion 112 . The second adhesive area 118 is provided at a position facing the first adhesive area 101 when attached to the support member 100 . In the present embodiment, the second bonding region 118 has a convex shape that protrudes from the surface 116A in the Z2 direction, but is not limited thereto. It may be formed flush with surface 116A without being recessed or protruding from surface 100A.

カバー部112のZ2方向側の表面112Aには、梁部119が形成されている。梁部119は、側部114の1つの内面から、その内面に対向する側部114の内面まで延在する梁状の部材である。本実施形態では、梁部119として、一方向に延在する2本の梁部119Aと、一方向に直交する方向に延在する1本の梁部119Bとが設けられているが、梁部119の数及び設けられる位置は、任意であってよい。また、梁部119は必須の構成ではない。 A beam portion 119 is formed on the surface 112A of the cover portion 112 on the Z2 direction side. The beam portion 119 is a beam-like member extending from one inner surface of the side portion 114 to the inner surface of the side portion 114 opposite to the inner surface. In this embodiment, as the beams 119, two beams 119A extending in one direction and one beam 119B extending in a direction perpendicular to the one direction are provided. The number and position of 119 may be arbitrary. Also, the beam portion 119 is not an essential component.

カバー部材110の表面110Aには、圧入部120が形成されている。圧入部120は、表面110AからZ2方向側(支持部材100側)に突出する軸状の部材である。圧入部120は、支持部材100の孔部106に圧入される。 A press-fit portion 120 is formed on the surface 110A of the cover member 110 . The press-fit portion 120 is a shaft-shaped member that protrudes from the surface 110A toward the Z2 direction side (the support member 100 side). The press-fit portion 120 is press-fit into the hole portion 106 of the support member 100 .

図6は、圧入部の模式的な拡大図である。図6に示すように、圧入部120は、第1部分122と第2部分124とを含む。第1部分122は、表面110AからZ2方向に突出する。第1部分122は、Z方向から見た場合に、一方の端部122Aから他方の端部122Bまで第1方向D1に延在する。第2部分124は、表面110AからZ2方向に突出する。第2部分124は、Z方向から見た場合に、端部122Aが第1部分122に接続されており、端部122Aから他方の端部124Bまで、第1方向D1とは異なる第2方向D2に延在する。すなわち、第1部分122及び第2部分124は、Z方向から見た場合に、同じ端部122Aから異なる方向に延在している。すなわち、圧入部120は、第1部分122及び第2部分124を含む二又形状になっているといえる。本実施形態では、圧入部120は、第1部分122及び第2部分124を含むL字状であるともいえるが、例えば、Z方向から見た場合にU字状、V字状やC字状であってもよい。ただし、圧入部120の形状は、以上の説明に限られず任意であってよく、例えばZ方向から見てS字状、楕円状などであってもよい。 FIG. 6 is a schematic enlarged view of the press-fit portion. As shown in FIG. 6, the press-fit portion 120 includes a first portion 122 and a second portion 124 . The first portion 122 protrudes in the Z2 direction from the surface 110A. The first portion 122 extends in the first direction D1 from one end 122A to the other end 122B when viewed in the Z direction. The second portion 124 protrudes in the Z2 direction from the surface 110A. The second portion 124 has an end portion 122A connected to the first portion 122 when viewed in the Z direction, and extends from the end portion 122A to the other end portion 124B in a second direction D2 different from the first direction D1. extend to That is, the first portion 122 and the second portion 124 extend in different directions from the same end portion 122A when viewed in the Z direction. That is, it can be said that the press-fit portion 120 has a bifurcated shape including the first portion 122 and the second portion 124 . In the present embodiment, the press-fit portion 120 can be said to be L-shaped including the first portion 122 and the second portion 124. However, for example, when viewed from the Z direction, the press-fit portion 120 can be U-shaped, V-shaped, or C-shaped. may be However, the shape of the press-fit portion 120 is not limited to the above description and may be arbitrary, and may be, for example, an S shape or an elliptical shape when viewed from the Z direction.

また、本実施形態では、圧入部120は、Z2方向の端部(先端)が切り欠かれており、Z2方向側に向かうに従って断面積が小さくなる形状になっているといえる。図6の例では、端部122A、122B、124Bの先端が切り欠かれている。また、圧入部120は、Z1方向に向かって広がるテーパ形状となっており、表面110AからZ2方向に向けて断面積が小さくなっている。 In addition, in the present embodiment, the press-fit portion 120 has a notched end (tip) in the Z2 direction, and can be said to have a shape in which the cross-sectional area decreases toward the Z2 direction. In the example of FIG. 6, the tips of the ends 122A, 122B, 124B are notched. The press-fit portion 120 has a tapered shape that widens in the Z1 direction, and the cross-sectional area decreases from the surface 110A in the Z2 direction.

圧入部120は、複数形成されており、本実施形態においては、圧入部120A、120B、120Cの3つが形成されている。圧入部120Aは、カバー部材110が支持部材100に取り付けられた際に、孔部106Aに圧入可能な位置(Z方向から見て孔部106Aと重なる位置)に設けられ、圧入部120Bは、カバー部材110が支持部材100に取り付けられた際に、孔部106Bに圧入可能な位置(Z方向から見て孔部106Bと重なる位置)に設けられ、圧入部120Cは、カバー部材110が支持部材100に取り付けられた際に、孔部106Cに圧入可能な位置(Z方向から見て孔部106Cと重なる位置)に設けられる。 A plurality of press-fitting portions 120 are formed, and in this embodiment, three press-fitting portions 120A, 120B, and 120C are formed. The press-fit portion 120A is provided at a position where it can be press-fitted into the hole portion 106A when the cover member 110 is attached to the support member 100 (a position overlapping the hole portion 106A when viewed from the Z direction). When the member 110 is attached to the support member 100, the press-fit portion 120C is provided at a position where it can be press-fitted into the hole portion 106B (a position overlapping the hole portion 106B when viewed from the Z direction). It is provided at a position where it can be press-fitted into the hole 106C (a position overlapping the hole 106C when viewed from the Z direction) when it is attached to the body.

図7は、圧入部の向きを説明するための模式図である。ここで、Z方向から見た場合の、圧入部120の外周面上の任意の2点を結んだ直線のうちで、直線が最長となる外周面上の2点の位置を、第1圧入箇所122B1及び第2圧入箇所124B1とする。すなわち、第1圧入箇所122B1及び第2圧入箇所124B1は、圧入部120において最も径方向外側に突出している箇所といえる。ここでの径方向とは、圧入部120の中心軸を軸方向とした場合の径方向である。本実施形態では、圧入部120がL字であるため、図7に示すように、第1圧入箇所122B1は、端部122Bの径方向外側の点となり、第2圧入箇所124B1は、端部124Bの径方向外側の点となる。 FIG. 7 is a schematic diagram for explaining the orientation of the press-fit portion. Here, among the straight lines connecting any two points on the outer peripheral surface of the press-fit portion 120 when viewed from the Z direction, the positions of the two points on the outer peripheral surface where the straight line is the longest are defined as the first press-fit locations. 122B1 and a second press-fit portion 124B1. That is, the first press-fitting portion 122B1 and the second press-fitting portion 124B1 can be said to be portions of the press-fitting portion 120 that protrude radially outward most. The radial direction here is the radial direction when the central axis of the press-fit portion 120 is taken as the axial direction. In the present embodiment, since the press-fit portion 120 is L-shaped, as shown in FIG. is a point radially outside of

圧入部120は、孔部106に圧入される前の第1圧入箇所122B1と第2圧入箇所124B1とを結んだ直線が、孔部106の内径よりも大きくなっている。従って、第2圧入箇所124B1は、孔部106内に挿入された際に締り嵌め(圧入)され、第1圧入箇所122B1及び第2圧入箇所124B1が、径方向内側に弾性変形しつつ(すなわち第1圧入箇所122B1と第2圧入箇所124B1とが近づく方向に変形しつつ)、孔部106の内周面に接触する。すなわち、第1圧入箇所122B1及び第2圧入箇所124B1は、圧入部120の外周面における、孔部106の内周面に弾性変形しつつ接触する箇所であるといえる。なお、圧入部120は、第1圧入箇所122B1及び第2圧入箇所124B1のみが弾性変形して孔部106の内周面に接触することに限られず、第1圧入箇所122B1及び第2圧入箇所124B1以外の箇所も、弾性変形して孔部106の内周面に接触してよい。この場合、第1圧入箇所122B1及び第2圧入箇所124B1は、外周面において、径方向内側への弾性変形量が最も大きくなる箇所であるといえる。従って、例えば、孔部106に圧入された圧入部120を孔部106から引き抜いた場合には、第1圧入箇所122B1及び第2圧入箇所124B1は、圧入部120の外周面上の任意の2点を結んだ直線のうちで、直線が最長となる外周面上の二点の位置になるといえる。 In the press-fit portion 120 , a straight line connecting the first press-fit portion 122 B 1 and the second press-fit portion 124 B 1 before being press-fitted into the hole portion 106 is larger than the inner diameter of the hole portion 106 . Therefore, the second press-fitting portion 124B1 is interference-fitted (press-fitted) when inserted into the hole portion 106, and the first press-fitting portion 122B1 and the second press-fitting portion 124B1 elastically deform radially inward (that is, the second press-fitting portion 124B1). The first press-fit portion 122B1 and the second press-fit portion 124B1 come into contact with the inner peripheral surface of the hole portion 106 while deforming in a direction toward each other. That is, it can be said that the first press-fitting portion 122B1 and the second press-fitting portion 124B1 are portions of the outer peripheral surface of the press-fitting portion 120 that come into contact with the inner peripheral surface of the hole portion 106 while being elastically deformed. It should be noted that the press-fit portion 120 is not limited to being elastically deformed only at the first press-fit portion 122B1 and the second press-fit portion 124B1 to contact the inner peripheral surface of the hole portion 106. Other locations may be elastically deformed and come into contact with the inner peripheral surface of the hole 106 . In this case, it can be said that the first press-fit portion 122B1 and the second press-fit portion 124B1 are portions where the amount of radially inward elastic deformation is the largest on the outer peripheral surface. Therefore, for example, when the press-fit portion 120 press-fitted into the hole portion 106 is pulled out from the hole portion 106, the first press-fit portion 122B1 and the second press-fit portion 124B1 are any two points on the outer peripheral surface of the press-fit portion 120. It can be said that it is the two points on the outer peripheral surface where the straight line is the longest among the straight lines connecting .

図7に示すように、Z方向から見て、圧入部120の第1圧入箇所122B1と第2圧入箇所124B1とを結んだ線を、線Lとする。また、Z方向から見て、複数の圧入部120の重心(幾何中心)を、重心Pとする。この場合、圧入部120は、Z方向から見て、線Lが、圧入部120と重心Pとを結ぶ線Dに対して交差するような向きで、設けられている。すなわち、圧入部120は、線Lが線Dと交差するように、第1圧入箇所122B1と第2圧入箇所124B1との位置(向き)が設定されているといえる。より好ましくは、圧入部120は、Z方向から見て、線Lが線Dに対して直交するように、すなわち線Lに直交する線が線Dに沿うように、設けられている。図7の例では、圧入部120Aは、第1圧入箇所122B1と第2圧入箇所124B1とを結ぶ線LAが、圧入部120Aと重心Pとを結ぶ線DAに交差(ここでは直交)している。同様に、圧入部120Bは、第1圧入箇所122B1と第2圧入箇所124B1とを結ぶ線LBが、圧入部120Bと重心Pとを結ぶ線DBに交差(ここでは直交)しており、圧入部120Cは、第1圧入箇所122B1と第2圧入箇所124B1とを結ぶ線LBが、圧入部120Cと重心Pとを結ぶ線DCに交差(ここでは直交)している。また、それぞれの圧入部120の線Lは、すなわち図7の例における線LA、LB、LCは、Z方向から見て、それぞれ異なる角度となっている(互いに交差する)。ただしそれに限られず、例えば、圧入部120(ここでは圧入部120A、120B、120C)が、Z2方向から見て多角形状(ここでは三角形状)に配置されており、言い換えれば、圧入部120がそれぞれ多角形(ここでは三角形)の頂点に対応する位置に配置されており、それぞれの線L(ここでは線LA、LB、LC)の少なくとも1つが、他の線Lに対して、異なる角度であってよい。 As shown in FIG. 7, a line connecting the first press-fitting portion 122B1 and the second press-fitting portion 124B1 of the press-fit portion 120 when viewed from the Z direction is defined as a line L. As shown in FIG. Also, let P be the center of gravity (geometric center) of the plurality of press-fitting portions 120 when viewed from the Z direction. In this case, the press-fit portion 120 is provided in such a direction that the line L intersects the line D connecting the press-fit portion 120 and the center of gravity P when viewed from the Z direction. That is, it can be said that the positions (orientations) of the first press-fit portion 122B1 and the second press-fit portion 124B1 are set such that the line L intersects the line D in the press-fit portion 120 . More preferably, the press-fit portion 120 is provided so that the line L is orthogonal to the line D, that is, the line orthogonal to the line L is along the line D when viewed from the Z direction. In the example of FIG. 7, in the press-fitting portion 120A, the line LA connecting the first press-fitting portion 122B1 and the second press-fitting portion 124B1 intersects (here, orthogonally) the line DA connecting the press-fitting portion 120A and the center of gravity P. . Similarly, in the press-fitting portion 120B, the line LB connecting the first press-fitting portion 122B1 and the second press-fitting portion 124B1 intersects (here, is perpendicular to) the line DB connecting the press-fitting portion 120B and the center of gravity P. At 120C, a line LB connecting the first press-fit portion 122B1 and the second press-fit portion 124B1 intersects (here, orthogonally) a line DC connecting the press-fit portion 120C and the center of gravity P. Also, the lines L of the respective press-fit portions 120, that is, the lines LA, LB, and LC in the example of FIG. 7 have different angles (intersect each other) when viewed from the Z direction. However, not limited to this, for example, the press-fitting portions 120 (here, press-fitting portions 120A, 120B, and 120C) are arranged in a polygonal shape (here, a triangular shape) when viewed from the Z2 direction. are arranged at positions corresponding to the vertices of a polygon (here, a triangle), and at least one of the respective lines L (here, lines LA, LB, LC) is at a different angle with respect to the other lines L. you can

ただし、圧入部120の向きや設けられる数は、上記の説明に限られず任意であってよい。 However, the orientation and the number of press-fitting portions 120 are not limited to those described above and may be arbitrary.

(カバー部材の取付状態)
カバー部材110は、以上説明したような構造となっている。以下、カバー部材110が支持部材100に取り付けられた状態を説明する。
(Mounting state of the cover member)
The cover member 110 has the structure described above. A state in which the cover member 110 is attached to the support member 100 will be described below.

図8は、カバー部材が取り付けられた状態における電子部品の模式的な上面図である。図1及び図8に示すように、カバー部材110は、表面110Aが支持部材100の表面100Aに対向し、支持部材100上の電子基板70を覆うように、支持部材100に取り付けられている。すなわち、図8に示すように、カバー部材110は、支持部材100の第1接着領域101より内側の領域(領域AR1及び領域AR2)を覆い、Z方向から見て、カバー部112の表面112Aが、電子基板70に重なる。なお、カバー部材110が支持部材100に取り付けられた際には、カバー部材110のZ2方向側の表面110Aのうちの、固定部116の表面116Aは、少なくとも一部が支持部材100の表面100Aに接触するが、カバー部112の表面112Aは、支持部材100の表面100Aに接触せず、表面100A及び電子基板70からZ1方向側に離れた位置にある。 FIG. 8 is a schematic top view of the electronic component with the cover member attached. As shown in FIGS. 1 and 8, the cover member 110 is attached to the support member 100 so that the surface 110A faces the surface 100A of the support member 100 and covers the electronic substrate 70 on the support member 100. FIG. That is, as shown in FIG. 8, the cover member 110 covers the regions (regions AR1 and AR2) inside the first adhesion region 101 of the support member 100, and when viewed from the Z direction, the surface 112A of the cover portion 112 is , overlies the electronic substrate 70 . When the cover member 110 is attached to the support member 100, at least a portion of the surface 116A of the fixed portion 116 of the surface 110A on the Z2 direction side of the cover member 110 is on the surface 100A of the support member 100. However, the surface 112A of the cover portion 112 does not contact the surface 100A of the support member 100 and is located away from the surface 100A and the electronic substrate 70 in the Z1 direction.

より詳しくは、カバー部材110は、圧入部120が、支持部材100の孔部106に圧入されつつ、第2接着領域118が、支持部材100の第1接着領域101に接着材(硬化した接着剤)を介して固定(接着)されている。本実施形態では、凸形状の第2接着領域118が、溝形状の第1接着領域101内に挿入されて、第2接着領域118と第1接着領域101との間にある接着材を介して固定されている。ただし、第2接着領域118と第1接着領域101とは、それぞれ凸形状及び溝形状であることに限られない。例えば、第1接着領域101と第2接着領域118との一方が溝状であり、第1接着領域101と第2接着領域118とのとの他方が凸状であり、第1接着領域101と第2接着領域118とのうちの一方の溝内に、第1接着領域101と第2接着領域118とのうちの他方が挿入された状態で固定されていてもよい。 More specifically, the cover member 110 is such that the press-fit portion 120 is press-fitted into the hole portion 106 of the support member 100 while the second adhesive region 118 is adhered to the first adhesive region 101 of the support member 100 with an adhesive (hardened adhesive). ) is fixed (bonded) via In this embodiment, the convex-shaped second adhesive region 118 is inserted into the groove-shaped first adhesive region 101 , through the adhesive between the second adhesive region 118 and the first adhesive region 101 . Fixed. However, the second bonding area 118 and the first bonding area 101 are not limited to having the convex shape and the groove shape, respectively. For example, one of the first bonding region 101 and the second bonding region 118 is groove-shaped, and the other of the first bonding region 101 and the second bonding region 118 is convex. The other of the first adhesive region 101 and the second adhesive region 118 may be inserted and fixed in the groove of one of the second adhesive regions 118 .

このように、カバー部材110が電子基板70を覆うことで、電子基板70や、電子基板70のZ2方向側の開口部102、105への水や異物の侵入が抑制される。なお、本実施形態では、カバー部材110は、Z方向から見て、支持部材100の全域にわたって重なっておらず、支持部材100の第1接着領域101の外側の少なくとも一部には重ならない。従って、支持部材100は、表面100Aのうち、電子基板70と重ならない領域の少なくとも一部が、カバー部材110に覆われずに露出している。ただし、カバー部材110は、Z方向から見て、支持部材100の一部のみに重なることに限られず、支持部材100の全域に重なっていてもよい。 By covering the electronic substrate 70 with the cover member 110 in this manner, entry of water and foreign matter into the electronic substrate 70 and the openings 102 and 105 of the electronic substrate 70 on the Z2 direction side is suppressed. Note that in the present embodiment, the cover member 110 does not overlap the entire area of the support member 100 when viewed in the Z direction, and does not overlap at least a portion of the outside of the first adhesion region 101 of the support member 100 . Therefore, at least a portion of the surface 100A of the support member 100 that does not overlap the electronic substrate 70 is exposed without being covered with the cover member 110 . However, the cover member 110 is not limited to overlapping only a part of the support member 100 when viewed from the Z direction, and may overlap the entire support member 100 .

以上説明したように、カバー部材110は、支持部材100上に搭載されている電子基板70を覆う。カバー部材110に覆われる対象となる電子基板70は、本実施形態では、コネクタ部80と制御基板62とを電気的に接続する接続基板であるが、コネクタ部80と制御基板62とを電気的に接続するものに限られない。すなわち、カバー部材110は、支持部材100上に搭載される任意の用途の電子基板を覆うものであってもよい。 As described above, the cover member 110 covers the electronic board 70 mounted on the support member 100 .

(Method for manufacturing electronic component)
Next, a method for manufacturing the electronic component 1 will be described. FIG. 9 is a flow chart illustrating the method for manufacturing an electronic component according to this embodiment. As shown in FIG. 9, in this manufacturing method, the electronic board 70 is mounted on the surface 100A of the support member 100 (step S10). In this embodiment, the electronic board 70 is mounted on the area AR1 of the surface 100A of the support member 100, the connector section 80 is passed through the opening 105 of the support member 100, and the electronic board 70 and the connector section 80 are connected. The connection member 90 is passed through the opening 102 of 100 to connect the electronic substrate 70 and the connection member 90 , and the connection member 90 and the control substrate 62 are connected. In this manufacturing method, an adhesive is applied to the first adhesive region 101 of the support member 100 (step S12), and the surface 110A of the cover member 110 faces the surface 100A of the support member 100. While press-fitting the press-fit portion 120 into the hole 106 of the support member 100, the first adhesion region 101 of the support member 100 and the second adhesion region 118 of the cover member 110 are adhered with an adhesive (step S14). Although the adhesive is applied to the first adhesive area 101 here, the adhesive may be applied to at least one of the first adhesive area 101 and the second adhesive area 118 without being limited thereto. After that, the adhesive is cured to form an adhesive, and the first adhesive region 101 and the second adhesive region 118 are fixed through the adhesive (step S16). As a result, the electronic substrate 70 on the support member 100 is covered with the cover member 110 .

(効果)
以上説明したように、本実施形態に係る電子部品1は、電子基板70と、支持部材100と、カバー部材11とを有する。支持部材100は、表面100Aに電子基板70が搭載され、電子基板70が搭載される領域AR1の周囲に第1接着領域101が形成され、電子基板70と重ならない領域に孔部106が形成される。カバー部材110は、電子基板70を覆うように支持部材100に取り付けられている。カバー部材110は、支持部材100に対向する表面110Aに形成されて支持部材100側に突出する圧入部120が、孔部106に圧入され、表面110Aに形成される第2接着領域118が、接着材を介して第1接着領域101に固定されている。
(effect)
As described above, the electronic component 1 according to this embodiment has the electronic substrate 70 , the support member 100 and the cover member 11 . The support member 100 has the electronic substrate 70 mounted on the front surface 100A, the first adhesive region 101 formed around the region AR1 where the electronic substrate 70 is mounted, and the hole 106 formed in the region that does not overlap the electronic substrate 70. be. The cover member 110 is attached to the support member 100 so as to cover the electronic substrate 70 . In the cover member 110, a press-fit portion 120 formed on a surface 110A facing the support member 100 and protruding toward the support member 100 is press-fitted into the hole 106, and a second adhesion region 118 formed on the surface 110A is adhered. It is fixed to the first adhesion region 101 via a material.

ここで、電子部品1は、カバー部材110を適切に固定することが求められている。それに対して、本実施形態に係る電子部品1は、圧入部120を孔部106に圧入しつつ、第2接着領域118を第1接着領域101に対して接着材で固定している。そのため、接着剤が硬化するまでの間、圧入部120の圧入によりカバー部材110を支持部材100に対して仮に固定して、位置決めをすることが可能となる。また、仮固定に、圧入部120による圧入を用いることで、ねじによる螺合作業が不要となり、作業負荷やコストが高くなることも抑制できる。従って、本実施形態によると、カバー部材110を適切に固定することが可能となる。なお、圧入部120は、孔部106に圧入された後にクリープを起こし、圧入力が低下する場合もあるが、第2接着領域118と第1接着領域101とが接着材で固定されるため、圧入力が低下しても問題ないといえる。 Here, the electronic component 1 is required to properly fix the cover member 110 . On the other hand, in the electronic component 1 according to the present embodiment, the press-fit portion 120 is press-fitted into the hole portion 106 while the second adhesive region 118 is fixed to the first adhesive region 101 with an adhesive. Therefore, until the adhesive hardens, it is possible to temporarily fix the cover member 110 to the support member 100 by press-fitting the press-fitting portion 120 for positioning. Moreover, by using the press-fitting by the press-fitting portion 120 for the temporary fixation, it is possible to eliminate the screwing work with screws, thereby suppressing an increase in work load and cost. Therefore, according to this embodiment, it is possible to properly fix the cover member 110 . The press-fitting portion 120 may creep after being press-fitted into the hole 106, and the press-fitting force may decrease. It can be said that there is no problem even if the pressing force decreases.

孔部106は、第1接着領域101よりも内側に形成され、支持部材100の表面100Aから反対側の表面100B(裏面)まで貫通している。孔部106をこのように貫通穴とすることで、表面100Bからの加工が可能となり、表面100Bの他の箇所と同時に加工できるため、加工工程の負荷を低減できる。また、孔部106を第1接着領域101よりも内側に形成することで、カバー部材110によって覆われて、水や異物などが孔部106に侵入することを抑制できる。 The hole portion 106 is formed inside the first adhesion region 101 and penetrates from the surface 100A of the support member 100 to the opposite surface 100B (back surface). By forming the hole 106 as a through hole in this way, it becomes possible to process from the surface 100B, and it is possible to process other parts of the surface 100B at the same time, so that the load of the processing process can be reduced. Further, by forming the hole portion 106 inside the first adhesion region 101 , the hole portion 106 is covered with the cover member 110 to prevent water, foreign matter, and the like from entering the hole portion 106 .

孔部106と圧入部120とは、それぞれ複数形成されている。孔部106と圧入部120を複数形成することで、圧入部120の圧入により、カバー部材110を支持部材100に適切に固定できる。 A plurality of hole portions 106 and press-fit portions 120 are formed. By forming a plurality of hole portions 106 and press-fitting portions 120 , the cover member 110 can be appropriately fixed to the support member 100 by press-fitting the press-fitting portions 120 .

複数の圧入部120は、三角形状に配置されており、外周面に、孔部106の内周面に弾性変形しつつ接触する第1圧入箇所122B1と第2圧入箇所124B1とを備え、突出方向(Z方向)から見て、第1圧入箇所122B1と第2圧入箇所124B1とを結ぶ線L(本実施形態の例では線LA、LB、LC)の少なくとも1つが、異なる角度である。ここで、第1圧入箇所122B1と第2圧入箇所124B1は、圧入力が高くなる箇所であるため、線Lに沿う方向は、圧入部120が動き難く、線Lと交差する方向には圧入部120が動きやすい。そのため、各圧入部120の線Lの少なくとも1つを、異なる角度とすることで、圧入部120を孔部106の位置に合わせるように動かしやすくして、位置の誤差を吸収することができる。従って、本実施形態によると、圧入部120を孔部106に適切に圧入できる。より詳しくは、圧入部120は、線Lと交差する方向には撓みやすいため、孔部106への挿入時に圧入部120を孔部106に定めやすくなる。また、圧入部120は、孔部106に対する線Lに沿う方向には動き難く、複数の圧入部120の線Lの少なくとも1つが異なる角度であるため、圧入部120を孔部106に挿入すると、カバーが動き難くなる。すなわち、これによりカバーが固定されて、接着剤が硬化するまで、圧入部120でカバーの位置を保持できる。 The plurality of press-fitting portions 120 are arranged in a triangular shape, and are provided with a first press-fitting portion 122B1 and a second press-fitting portion 124B1 that contact the inner peripheral surface of the hole portion 106 while being elastically deformed. At least one of the lines L connecting the first press-fitting portion 122B1 and the second press-fitting portion 124B1 (lines LA, LB, and LC in the example of the present embodiment) has a different angle when viewed from (the Z direction). Here, since the first press-fit portion 122B1 and the second press-fit portion 124B1 are places where the press-fit force is high, the press-fit portion 120 is difficult to move in the direction along the line L, and the press-fit portion 120 is difficult to move in the direction intersecting the line L. 120 is easy to move. Therefore, by setting at least one line L of each press-fitting portion 120 at a different angle, the press-fitting portion 120 can be easily moved so as to align with the position of the hole portion 106, and positional error can be absorbed. Therefore, according to the present embodiment, the press-fitting portion 120 can be properly press-fitted into the hole portion 106 . More specifically, since the press-fit portion 120 is easily bent in the direction intersecting the line L, the press-fit portion 120 can be easily fixed in the hole portion 106 when inserted into the hole portion 106 . In addition, the press-fitting portion 120 is difficult to move in the direction along the line L with respect to the hole portion 106, and at least one of the lines L of the plurality of press-fitting portions 120 has a different angle. The cover becomes difficult to move. That is, this secures the cover so that the press-fit portion 120 can hold the position of the cover until the adhesive hardens.

圧入部120は、突出方向(Z方向)から見て、第1圧入箇所122B1と第2圧入箇所124B1とを結ぶ線Lが、複数の圧入部120を結ぶ三角形の重心Pと圧入部120とを結ぶ線Dに直交している。線Lを線Dに直交させることで、圧入部120を孔部106の位置に合わせるように動かしやすくし、圧入部120を孔部106に適切に圧入できる。より詳しくは、線Lを、重心Pと圧入部120とを結ぶ線Dと直交するように配置することで、孔部106への挿入時には、圧入部120を孔部106に定めやすし、挿入後には、カバーを動き難くすることでカバーの位置を保持できる。 When viewed from the projecting direction (Z direction), the press-fitting portion 120 has a line L connecting the first press-fitting portion 122B1 and the second press-fitting portion 124B1. It is perpendicular to the connecting line D. By making the line L perpendicular to the line D, the press-fitting portion 120 can be easily moved to match the position of the hole portion 106 , and the press-fitting portion 120 can be properly press-fitted into the hole portion 106 . More specifically, by arranging the line L so as to be orthogonal to the line D connecting the center of gravity P and the press-fitting portion 120, it becomes easier to set the press-fitting portion 120 in the hole 106 when inserting the press-fitting portion 120 into the hole 106. can hold the position of the cover by making it difficult to move the cover.

圧入部120は、突出方向(Z方向)から見て、L字形状である。本実施形態においては、圧入部120をこのような形状とすることで、孔部106に圧入した際に、径方向内側に、すなわち断面積を小さくする方向に変形して、圧入力を適切に発揮できる。 The press-fit portion 120 has an L shape when viewed from the projecting direction (Z direction). In the present embodiment, the press-fitting portion 120 having such a shape deforms radially inward, that is, in a direction to reduce the cross-sectional area when press-fitted into the hole 106, thereby appropriately applying the press-fitting force. I can do it.

また、本実施形態においては、第1接着領域101と第2接着領域118との一方が溝状であり、第1接着領域101と第2接着領域118とのとの他方が凸状であり、第1接着領域101と第2接着領域118とのうちの一方の溝内に、第1接着領域101と第2接着領域118とのうちの他方が挿入された状態で固定される。このように溝と凸とを嵌め合わせるラビリンス形状とすることで、内部を適切に密封できる。なお、第1接着領域101と第2接着領域118とはラビリンス形状であることに限られず、段差によるクランク形状を形成することで、密封してもよい。 Further, in the present embodiment, one of the first adhesion region 101 and the second adhesion region 118 is groove-shaped, and the other of the first adhesion region 101 and the second adhesion region 118 is convex, The other of the first adhesion region 101 and the second adhesion region 118 is inserted into the groove of one of the first adhesion region 101 and the second adhesion region 118 and fixed. By forming the labyrinth shape in which the groove and the protrusion are fitted in this way, the inside can be properly sealed. The first bonding area 101 and the second bonding area 118 are not limited to the labyrinth shape, and may be sealed by forming a crank shape with a step.

That is, at least one of the control board 62 and the electronic board 70 can be appropriately cooled while suppressing an increase in size.

また、電子部品1は、ケーシング10と、ケーシング10内に設けられるモータ16とを更に有し、制御基板62は、ケーシング10内に設けられる。本実施形態においては、モータ16用のケーシング10に制御基板62を搭載することで、サイズが大きくなることを抑制できる。 The electronic component 1 further includes a casing 10 and a motor 16 provided inside the casing 10 , and the control board 62 is provided inside the casing 10 . In the present embodiment, by mounting the control board 62 on the casing 10 for the motor 16, an increase in size can be suppressed.

また、本製造方法は、支持部材100の表面100Aに電子基板70を搭載するステップと、電子基板70を覆うように支持部材100の表面100Aにカバー部材110を取り付けるステップとを含む。カバー部材110を取り付けるステップにおいては、支持部材100の電子基板70に重ならない領域に形成される孔部106に、支持部材100に対向するカバー部材110の表面110Aに形成される圧入部120を圧入しつつ、支持部材100の電子基板70が搭載される領域AR1の周囲の第1接着領域101と、カバー部材110の表面110Aに形成される第2接着領域118とを、接着剤を介して接着し、接着剤を硬化させることで、第1接着領域101と第2接着領域118とを固定する。本製造方法によると、圧入部120を孔部106に圧入しつつ、第2接着領域118を第1接着領域101に対して接着材で固定している。そのため、本実施形態によると、カバー部材110を適切に固定することが可能となる。 The manufacturing method also includes the steps of mounting the electronic substrate 70 on the surface 100A of the support member 100 and attaching the cover member 110 to the surface 100A of the support member 100 so as to cover the electronic substrate 70 .
