JP 2013-217886 A

In-vehicle electrical components include not only radar but also cameras. Furthermore, an electrical component in which a radar and a camera are integrated is also included. These electrical components acquire an external scene in front of the vehicle during driving and position information of an object included therein, and provide the driver with information for safe driving. In addition to this, other electrical components have a function of controlling automatic operation for avoiding danger. These electrical components are usually installed on the rear surface of the windshield of the vehicle or in the vicinity thereof in order to image a scene in front of the vehicle. In this case, the position information of the object included in the external scene is obtained based on the mounting position of the electrical component in the vehicle. Therefore, in order to accurately determine whether the vehicle operation is safe with this electrical component, it is essential that the vehicle mounting position of this electrical component does not change. In particular, the deviation of the optical axis of a camera or the like greatly affects the detection of the position of an object included in the external scene. On the other hand, when the passenger gets in and out of the passenger compartment, a part of the body or belongings may come into contact with the electrical equipment and collide. At that time, the mounting position of the electrical components must not change. If the position changes, the optical axis or radio wave transmission axis may change in the camera or radar. As a result, the position information regarding the scene in front of the vehicle is greatly shifted with respect to the vehicle. As a result, there is a case where it cannot be correctly determined whether or not the object included in the scene information collides with the vehicle.
On the other hand, it is also required not to injure the passenger's body due to the collision between the passenger and the electrical equipment. Therefore, when mounting an electrical component on a vehicle, it is also required to prevent injury to the human body by removing the electrical component when an impact of a certain level or more is applied to the electrical component.
Therefore, when mounting an in-vehicle electrical component on a vehicle, it is required that the electrical component mounting position does not change even if there is contact or collision with an occupant or the like. In addition, when a part of the human body collides with a certain level of strength, it is also required to remove the electrical components and prevent damage to the human body. Furthermore, such a fixture should have a simple structure in order to reduce manufacturing costs. Specifically, it is desirable that the fixture has a small number of springs and elastic members used.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a mounting device in which the mounting position of an electrical component does not change even when there is contact with an occupant or the like and the mounting structure is simple. To do.

  In order to solve the above-mentioned problem, an attachment according to the present invention is an attachment for attaching an in-vehicle electrical component on which at least one of a camera or a radar is mounted to a vehicle having a windshield, The vehicle-side attachment portion includes a vehicle-side attachment portion and an electrical component-side attachment portion, and the vehicle-side attachment portion has at least a rail receiver and an elastic portion extending in a rail direction, and the elastic portion is a first different from the rail direction. A first pressing portion that generates a first pressing force in a direction, and a second pressing portion that generates a second pressing force in a second direction that is not on a virtual plane determined by the rail direction and the first direction, The electrical component side mounting portion is opposed to the rail extending in the rail direction, the first pressure-receiving portion facing the first pressing portion and receiving at least a part of the first pressing force, and the second pressing portion. Second press A second pressure-receiving portion that receives at least a portion of the force, and the vehicle-side mounting portion receives a first pressing force of the first pressing portion via the first pressure-receiving portion. A receiving part; and a second receiving part that receives at least a part of the pressing force of the second pressing part via the second pressure-receiving part, and the rail receiver and the electrical component of the vehicle-side mounting part The rail of the product-side mounting portion is a fixture that is combined and fixed together by the first pressing force and the second pressing force.

  Here, the on-vehicle electrical components are devices including various electronic control units (ECUs), such as on-vehicle obstacle detection devices such as millimeter wave radars, laser radars, and cameras, and wiper devices. Sensors such as a rain sensor for automatically controlling and a solar radiation sensor for automatically controlling an air conditioner.

  According to this configuration, when the vehicle-side mounting portion and the electrical component-side mounting portion are combined by elastic force, the mounting tool is combined from two directions different from the combination direction (rail direction) by the rail and the rail receiver. Thereby, even if there exists a gap in the combination part of both, the position of both is fixed by applying the pressurization which fixes the state of this gap in the predetermined direction. Even when an electric shock or the like is applied to the electrical component fixed to the vehicle by the fixture, the gap state is maintained and no deviation or play occurs. In addition, according to the present invention, since the number of parts used is smaller than that of the conventional mounting structure, the manufacturing cost is low.

≪Mounting device for in-vehicle electrical components according to the embodiment≫
As shown in FIG. 1, the fixture 1 is configured by combining an electrical component side mounting portion 10 and a vehicle side mounting portion 20, and for mounting the in-vehicle electrical component 2 on the passenger compartment side of the windshield of the vehicle. belongs to. Here, the in-vehicle electrical component 2 is a device including various electronic control units (ECUs), and is an in-vehicle obstacle detection device such as a millimeter wave radar, a laser radar, or a camera. In the present embodiment, as shown in FIG. 2, a composite sensor including a millimeter wave radar 2 a and a camera 2 b in a housing 2 c is assumed as the in-vehicle electrical component 2. The in-vehicle electrical component 2 is a fixture in which the emission direction of radio waves (arrow α in FIG. 2) in the millimeter wave radar 2a and the imaging direction of the camera 2b (arrow β in FIG. 2) are directed in the traveling direction (front) of the vehicle. 1 is fixed.

  As shown in FIG. 3, a convex electrical component side mounting portion 10 that is attached to the fixture 1 is formed at the upper rear of the housing 2 c of the in-vehicle electrical component 2. The electrical component side attaching portion 10 may be formed integrally with the housing 2c, or may be configured as a separate member from the housing 2c. In the present embodiment, it is assumed that the electrical component side mounting portion 10 and the housing 2c are configured as separate members and joined. Below, the electrical component side attachment part 10 will be described first, and then the attachment 1 will be described.

<Electrical component side mounting part>
The electrical component side mounting portion 10 is provided in a convex shape on the upper surface of the in-vehicle electrical component 2. As shown in FIG. 4, the electrical component side mounting portion 10 has a substantially rectangular parallelepiped shape in which the upper surface 11 is inclined. The upper surface 11 is inclined with respect to the lower surface 12 by an angle θ (°). This inclination angle θ corresponds to the inclination angle of the windshield of the vehicle. That is, the inclination angle θ is appropriately selected depending on the inclination angle of the windshield of the vehicle to be attached. In general, the inclination angle of the windshield of a vehicle varies depending on the vehicle type and vehicle manufacturer. By preparing an electrical component side attachment portion having an inclination corresponding to each inclination angle in advance and selecting and using it at the time of attachment, the electrical component can be installed at a predetermined angle regardless of the vehicle type.
As shown in FIG. 5, the vehicle side mounting portion 20 is provided with an elastic portion 30. The elastic part 30 has a hanging part 32 and a bent part 33. On the front surface (inner surface) of the drooping portion 32, there is a second pressing portion 321 that inclines so that the thickness of the drooping portion 32 increases as it goes to the right (in the depth direction of the paper surface) in FIG. Further, on the upper surface of the bent portion 33, there is a first pressing portion 331 that is inclined so that the thickness of the bent portion 33 becomes thicker toward the right (in the depth direction of the drawing). The direction (first direction) of the first pressing force generated by the first pressing portion is the direction in which the electrical component side mounting portion 10 and the vehicle side mounting portion 20 are combined by the inclination of the first pressing portion 331 (combination). Direction or rail direction). Furthermore, the direction (second direction) of the second pressing force generated by the second pressing portion is a direction that is not on the virtual plane when a virtual plane determined by the combination direction and the first direction is assumed.
On the other hand, the electrical component side mounting portion 10 is provided with a first pressure-receiving portion 14 and a second pressure-receiving portion 17a having inclined surfaces that respectively match the inclination of the first pressing portion 331 and the inclination of the second pressing portion 321. Yes. By these pressure-receiving portions, a pressure obtained by combining the first pressing force and the second pressing force acts on the electrical component side mounting portion 10. The direction of this pressurization is different from the combination direction in which the electrical component side mounting portion 10 and the vehicle side mounting portion 20 are combined, and is also different from the vector on the virtual plane. As a result, the electrical component-side mounting portion 10 is fixed to the vehicle-side mounting portion 20 in such a direction that pressure is applied in the front-rear, left-right, and vertical directions, and the state electrical component-side mounting portion 10 does not fall off. As a result, even if there is a gap between the electrical component side mounting portion 10 and the vehicle side mounting portion 20, the state of this gap is maintained after these are temporarily fixed by the elastic body 30 of the present embodiment. . Even if an impact force is applied to the electrical component side mounting portion 10 from the outside, the state of this gap is maintained as long as the impact force does not exceed the applied pressure holding the state of the gap. Electrical components do not cause a position shift.

  The electrical component mounting portion 10 generates a second pressing force by elastic deformation of the elastic portion 30 at the mounting position of the vehicle side mounting portion 20, and the second pressing portion 321 of the hanging portion 32 that is inclined in the left-right direction is the rear surface 14. The (second pressure-receiving portion) is pressed, and the front surface 13 presses the inner surface 22aa (second receiving portion) of the front wall 22a of the vehicle-side mounting portion 20 forward and rightward by the pressing force. At that time, the electrical component mounting portion 10 is formed in a shape corresponding to the vehicle-side mounting portion 20. That is, the length of the upper surface 11 in the front-rear direction is slightly larger than the distance from the front wall 22a of the vehicle-side mounting portion 20 to the hanging portion 32 of the elastic portion 30. Thereby, in the attachment position of the vehicle side attachment part 20, the front surface 13 contact | abuts to inner surface 22aa of the front wall 22a, and the rear surface 14 contact | abuts to the inclined surface 321 of the hanging part 32 of the elastic part 30 (refer FIG. 7). Here, “contact” refers to contact in a state where pressure is applied. In addition, here, there is a gap between the front surface of the rail 16 and the rail receiver 23, and the front surface 13 of the electrical component mounting portion 10 first comes into contact with the inner surface 22 aa of the front wall 22 a by the second pressing force. It is said. Further, the length of the upper surface 11 in the left-right direction is preferably equal to the distance between the rail receivers 23 of the vehicle-side mounting portion 20. Thereby, in the attachment position of the vehicle side attaching part 20, both the side surfaces 15 and 15 contact | abut to the rail receivers 23 and 23 (refer FIG. 7).

  As shown in FIG. 4, rails 16, 16 projecting laterally are provided on both the left and right side surfaces 15, 15 of the electrical component side mounting portion 10. This rail 16 is used to guide the mounting position when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20. The rail 16 has a shape corresponding to a rail receiver 23 of the vehicle side mounting portion 20 described later. Here, the rail 16 has a vertically long shape, and the central axis in the length direction is orthogonal to the upper surface 11 (parallel to the front surface 13 and the rear surface 14).

  Further, as shown in FIG. 5, a rear portion of the electrical component side mounting portion 10 has a concave portion 17 that is recessed forward. The concave portion 17 is a portion that comes into contact with the elastic portion 30 of the vehicle-side attachment portion 20 and receives a pressing force of the elastic portion 30 when attached to the vehicle-side attachment portion 20, and conforms to the shape of the elastic portion 30. Has a shape. Specifically, the concave portion 17 has a shape that contacts at least a part of the concave portion 17 along the first pressing portion 331 that is the bent portion 33 of the elastic portion 30. Here, the recess 17 includes a recess upper surface 17 a that is an inclined surface in which the thickness in the vertical direction of the recess 17 decreases toward the back in FIG. 5 with respect to the upper surface 11, and a recess front surface 17 b that is parallel to the front surface 13. It is configured. And in the rear part of the electrical equipment side attaching part 10, it is comprised with the material which continued from the one side 15 to the other side 15 (refer FIG. 6). The distance from the upper surface 11 to the inclined surface 17a of the upper surface of the concave portion is formed slightly larger than the vertical length of the inclined surface 321 of the hanging portion 32 of the elastic portion 30 at the fixing position of the electrical component side mounting portion 10. . By taking a certain distance from the upper surface 11 to the recess upper surface 17a, the length of the hanging portion 32 of the elastic portion 30 to be described later is increased to facilitate elastic deformation. Further, the distance from the rearmost portion of the rear surface 14 to the concave front surface 17b is formed to be larger than the length in the front-rear direction of the bent portion 33 of the elastic portion 30 described later. By making the distance from the rearmost part of the rear surface 14 to the concave front surface 17b larger than the bent portion 33, when the elastic portion 30 engages with the concave portion 17, the bent portion 33 does not contact the concave front surface 17b. can do.

<Vehicle side mounting part>
Then, the structure of the vehicle side attaching part 20 is demonstrated. The vehicle side mounting portion 20 supports the electrical component side mounting portion 10 and fixes the in-vehicle electrical component 2 (see FIG. 2) to the windshield. As shown in FIG. 5, the vehicle side mounting portion 20 includes a vehicle side mounting portion 20 and an elastic portion 30.

(Vehicle side mounting part)
As shown in FIG. 6, the vehicle-side mounting portion 20 includes a plate-shaped top plate portion 21, a wall portion 22 formed in a range half of the outer peripheral edge of the top plate portion 21, and the outer peripheral edge of the top plate portion 21. In this case, a pair of rail receivers 23, 23 formed at both ends of the wall portion 22 are provided. The vehicle side mounting portion 20 is made of, for example, a synthetic resin, and the top plate portion 21, the wall portion 22, and the rail receiver 23 are integrally formed.

  The top plate portion 21 is a plate material having a rectangular shape (plan view) viewed from above (see FIG. 4). An adhesive sheet (not shown) is installed on the upper surface 21 a of the top plate portion 21, and is fixed to the passenger compartment side of the windshield using this adhesive sheet. Note that a paste or liquid adhesive may be applied to the upper surface 21a of the top plate portion 21 instead of the adhesive sheet. Further, when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20, the upper surface 11 of the electrical component side mounting portion 10 contacts the lower surface 21 b of the top plate portion 21. The lower surface 21b of the top plate portion 21 is a first contact surface.

  As shown in FIG. 6, the wall portion 22 of the vehicle-side mounting portion 20 includes a front wall 22a that protrudes in a direction perpendicular to the front surface of the lower surface 21b of the top plate portion 21, and a lower surface 21b of the top plate portion 21 that is continuous with the front wall 22a. It consists of side walls 22b and 22b formed on the left and right sides, respectively. When the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20, the front surface 13 of the electrical component side mounting portion 10 abuts on the inner surface 22aa of the front wall 22 a (see FIG. 7). On the other hand, the inner surfaces 22ba of the side walls 22b are formed so that the side surface 15 of the electrical component side mounting portion 10 does not come into contact with the space when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20. (See FIG. 7). It is desirable that the height of the wall portion 22 is smaller than the height dimension of the front surface 13 of the electrical component side mounting portion 10. The height of the wall portion 22 is made smaller than the upper surface 11 of the electrical component side mounting portion 10 when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20 and the tip of the wall portion 22 is mounted on the vehicle. This is to prevent contact with the housing 2c (see FIG. 2) of the electrical component 2. Further, the side walls 22b and 22b are half the length of the entire side in this embodiment. Therefore, the side walls 22b, 22b are not formed on the rear side of the rail receivers 23, 23.

  Both rail receivers 23, 23 are arranged continuously to the wall portion 22 at positions substantially opposite to each other in the center of the vehicle-side mounting portion 20 in the front-rear width. Inside each rail receiver 23, there is a vertical groove 23a (vertical groove). The vertical groove 23a has a substantially U shape (U shape) as viewed from below (viewed from the bottom) (see FIG. 7). Both rail receivers 23, 23 are in contact with both side surfaces 15, 15 of the electrical component-side mounting portion 10 when the electrical component-side mounting portion 10 is combined with the vehicle-side mounting portion 20, and the vertical groove 23 a has the rail 16, 16 in combination. That is, the distance between the rail receivers 23 and 23 should be equal to the lateral width of the electrical component side mounting portion 10, and the shape and depth of the vertical groove 23 a should be matched to the dimensions of the rails 16 and 16. . Thereby, the rail receivers 23 and 23 can guide the electrical component side mounting portion 10 to the mounting position.

  Moreover, it is desirable that the vertical height of each rail receiver 23 is larger than the side wall 22b and smaller than the height of the central portion of the electrical component side mounting portion 10. The height of the rail receivers 23 and 23 is adjusted so that the electrical component side mounting portion 10 can be easily guided to the mounting position, and when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20, the rail receiver This is to prevent the tips of 23 and 23 from coming into contact with the housing 2c (see FIG. 2) of the in-vehicle electrical component 2.

(Elastic part)
In the present embodiment, the elastic portion 30 has a structure corresponding to a leaf spring having a predetermined strength and an inclined surface. As shown in FIG. 5, the elastic portion 30 includes a joining portion 31 joined to the lower surface 21 b (first contact surface) of the top plate portion 21, and a hanging portion 32 formed by bending downward from the joining portion 31. The bent portion 33 is formed by bending forward from the drooping portion 32, and the end portion 34 extends further downward from the bent portion 33. Here, the front surface of the hanging portion 32 has an inclined surface 321 that is inclined forward as it goes in the depth direction (right direction) of FIG. Further, the upper surface of the bent portion 33 has an inclined surface 331 which is inclined upward as it goes in the depth direction (right direction) of FIG. These inclined surfaces may be formed so that the leaf spring itself matches this shape. Alternatively, the leaf spring itself may not be provided with an inclined surface structure, but may be configured by adhering and fixing another triangular prism-shaped member having an inclined surface formed of resin or the like to the leaf spring.

  The joint portion 31 is a portion joined to the top plate portion 21 and may be joined to the top plate portion 21 by any means. For example, the joining portion 31 and the top plate portion 21 may be joined using a paste-like or liquid adhesive, or may be joined using a screw or the like. The position where the joining portion 31 is joined to the top plate portion 21 is the second pressing portion which is the inclined surface of the drooping portion 32 by generating a second pressing force by elastic deformation of the elastic portion 30 at the attachment position of the vehicle side attachment portion 20. 321 presses the second pressure-receiving portion 14 that is the inclined surface of the rear surface of the electrical component-side mounting portion 10, and the front surface 13 is pressed against the inner surface 22aa (second receiving portion) of the front wall 22 a of the vehicle-side mounting portion 20 by the pressing force. ) To the position where it is pressed forward and downward to the left. Here, the distance between the front wall 22a of the vehicle-side mounting portion 20 and the inclined surface 321 of the hanging portion 32 is the inclination of the front surface 13 and the rear surface of the electrical component-side mounting portion 10 at the combination fixing position of the electrical component-side mounting portion 10. It is slightly smaller than the dimension in the front-rear direction with the second pressure-receiving portion 14 that is a surface. As a result, the second pressing portion 321 that is the inclined surface of the hanging portion 32 abuts on the second pressure-receiving portion 14 that is the inclined surface of the rear surface of the electrical component side mounting portion 10 at the mounting position, and the electrical component side mounting portion 10. The pressure in the left front direction due to elastic deformation is transmitted to

The inclined surface 331 on the upper surface of the bent portion 33 abuts along at least a part of the concave portion 17 of the electrical component side mounting portion 10 (here, the inclined surface 17a (first pressure-receiving portion) on the upper surface of the concave portion) at the mounting position. . And the 1st press part 331 which is the contact part of this bending part 33 produces the 1st pressing force of the upper front left direction with an elastic deformation with respect to the electrical equipment side attaching part 10. FIG. The first pressing force is received by the lower surface 21 b (first receiving portion) of the vehicle side mounting portion 20 through the upper surface 11 of the electrical component side mounting portion 10 and the joint portion 31 of the elastic portion 33. As a result, the positioning and fixing of the electrical component side mounting portion 10 in the up / down / forward / left direction is realized. Here, the shape and dimensions of the bent portion 33 may be any as long as the electrical component side mounting portion 10 does not fall out of the vehicle side mounting portion 20 at the mounting position in consideration of the mass of the in-vehicle electrical component 10. Here, the bent portion 33 is substantially 90 ° with respect to the hanging portion 32. Note that the angle of the continuous portion 33a where the bent portion 33 and the end portion 34 are continuous should be moderate (approximately 30 ° to 60 °). The continuous portion 33a is for smoothly engaging the electrical component side mounting portion 10 with the bent portion 33 when the electrical component side mounting portion 10 is mounted on the vehicle side mounting portion 20 from below. The continuous portion 33a plays a role of a slide surface that abuts the corner portion of the electrical component side mounting portion 10 and elastically deforms the hanging portion 32 rearward.
As described above, the first pressing portion 331 and the second pressing portion 321 of the elastic portion 30 of the vehicle-side mounting portion 20 are inclined in the up / down / front / back / left / right directions with respect to the rail direction, so that these pressing forces are combined. The applied pressing force (hereinafter referred to as “synthetic pressing force”) acts on the electrical component side mounting portion 10. As a result, the electrical component side mounting portion 10 is pressed by the elastic portion 30 in the up / down, front / rear, left / right directions, and is securely fixed. At this time, the component force acting in the rail direction of the combined pressing force acts at least in the direction of pressing and fixing the electrical component side mounting portion 10 against the vehicle side mounting portion 20. Thereby, both are fixed and the dropout of the electrical component side attachment part 10 is prevented.
Moreover, even if there is a gap between the electrical component side mounting portion 10 and the vehicle side mounting portion 20 by the combined pressing force acting in the up / down / front / back / left / right directions with respect to the rail direction, It is held in a pressed state in the pressing direction. Even if an external force such as an external impact is applied to the electrical component side mounting portion 10, the previous gap state is restored by this combined pressing force. As a result, the mounting position of the electrical component-side mounting portion 10 is accurately held without causing a shift in the position where the electrical component-side mounting portion 10 is fixed to the vehicle.

  In addition, when removing the electrical equipment side attachment part 10 from the vehicle side attachment part 20, the end part 34 is for a person to push the elastic part 30 back backward. The end portion 34 is preferably disposed at the rear or the same position as the hanging portion 32 in the vertical direction. By engaging the end portion 34 backward, the engagement between the bent portion 33 and the concave portion 17 is canceled. In this state, the electrical component side mounting portion 10 is detached from the vehicle side mounting portion 20 by moving the electrical component side mounting portion 10 downward.

≪Usage of the fixture according to the embodiment≫
With reference to FIG. 8, the attachment method of the vehicle-mounted electrical component 2 using the vehicle side attachment part 20 is demonstrated.
First, a person who mounts the vehicle-mounted electrical component 2 (hereinafter referred to as “installer”) has a vehicle-side mounting portion at a predetermined position on the vehicle side of the windshield (for example, in front of the rearview mirror). 20 is fixed (see FIG. 8A). At this time, the direction of the vehicle-side mounting portion 20 is set so that the elastic portion 30 is rearward with respect to the traveling direction of the vehicle.

  Subsequently, the installer aligns the position of the rail 16 of the electrical component side mounting portion 10 with the vertical groove 23 a (see FIG. 6) of the rail receiver 23, and resists the elastic force of the elastic portion 30, so that the electrical component side mounting portion 10. Is pushed into the vehicle-side mounting portion 20 along the vertical groove 23a from below to above (see FIG. 8B). The vehicle-side mounting portion 20 receives the electrical component-side mounting portion 10 by elastically deforming the hanging portion 32 when the continuous portion 33a (see FIG. 5) of the elastic portion 30 is pressed, and moves the bent portion 33 rearward. .

  Further, when the electrical component side mounting portion 10 is pushed in until reaching the top plate portion 21 (see FIG. 6), the bent portion 33 of the elastic portion 30 moves forward so as to enter the concave portion 17 and engages with the concave portion 17. (See FIG. 8C). In the state shown in FIG. 8C, the hanging portion 32 presses the electrical component side mounting portion 10 forward, and the bent portion 33 presses the electrical component side mounting portion 10 upward. For this reason, even if vibration is generated as the vehicle travels, the in-vehicle electrical component 2 is firmly fixed to the vehicle-side mounting portion 20 and thus does not rattle.

And the rail receiver 23 of the vehicle side mounting portion 20 and the rail 16 of the electrical component side mounting portion 10 have the first pressing force and the second pressing force, respectively. It is the attachment tool 1 which is combined and fixed to each other.
In the above embodiment, the first receiving portion 21b and the second receiving portion 22aa are different surfaces. For example, a part of the first receiving portion 21b is inclined downward as it goes forward. Thus, the second pressing force can be received by the first receiving portion 21b, and the shape of the electrical component side mounting portion 10 corresponding thereto can be matched. In this case, the first receiving portion and the second receiving portion can be a common part.
Further, in the above, the electrical component side mounting portion 10 has an upper surface 11 and a lower surface 12, and the lower surface 12 is inclined with respect to the upper surface 11 at an angle θ as shown in FIG. This inclination angle θ corresponds to the inclination angle of the windshield of the vehicle. Thereby, the vehicle-mounted electrical component 2 can be attached to the vehicle in a certain direction without depending on the inclination angle of the windshield.
