DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Four embodiments (examples) of the vehicle mirror device according to the present invention will be described in detail below with reference to the drawings. Note that the drawings are schematic diagrams, and therefore main components are shown, and components other than the main components are omitted, and some hatching or cross sections are omitted. Furthermore, Figs. 13, 14, 15, 16, and 47 are shown in gray scale.

[0024] In this specification, front, rear, up, down, left and right refer to the front, rear, up, down, left and right when the vehicle mirror device according to the present invention is mounted on a vehicle (not shown).

[0025] (Description of the configuration of the first embodiment) 1 to 4 show a vehicle mirror device according to a first embodiment of the present invention. The configuration of the first embodiment is shown conceptually. The configuration of the vehicle mirror device according to the first embodiment will be described below. In FIGS. 1 to 4, reference numeral 1A denotes the vehicle mirror device according to the first embodiment.

[0026] (Description of vehicle mirror device 1A) In this example, the vehicle mirror device 1A is a door mirror for a vehicle (hereinafter, referred to as "door mirror 1A.") The door mirror 1A is provided on each of the left and right doors (not shown) of the vehicle.

[0027] The door mirror 1A installed on the left door will be described below. Here, in the door mirror 1A installed on the left door, the left side is the outside of the vehicle, while the right side is the inside of the vehicle. The door mirror installed on the right door is almost symmetrical in configuration to the door mirror 1A installed on the left door. For this reason, the description of the door mirror installed on the right door will be omitted.

[0028] As shown in Figures 1 to 4, the door mirror 1A includes a base 2A, a shaft 3A, a mirror housing 4A, a mirror 5A, a first drive unit 6A, a second drive unit 7A, a support member 8A, and a pivot mechanism 9A.

[0029] The base 2A is fixed to the vehicle body, in this example, to a door (not shown). The shaft 3A is fixed to the base 2A. In this example, the shaft 3A has a cylindrical shape. The center line of the shaft 3A constitutes a storage axis V0A-V0A.

[0030] The mirror housing 4A has a hollow shape with one surface (the surface facing the rear of the vehicle) open and the other surfaces closed. A mirror 5A is fixed to the opening on one surface of the mirror housing 4A. The mirror housing 4A and the mirror 5A form an accommodation space 40A.

[0031] An opening 41A is provided on the bottom surface of the mirror housing 4A near the door. In this example, the opening 41A has a circular shape. The shaft 3A is inserted through the opening 41A. As a result, the shaft 3A constituting the storage axis V0A-V0A extends through the opening 41A into and out of the storage space 40A.

[0032] The first drive unit 6A and the second drive unit 7A are each housed in the housing space 40A. The first drive unit 6A and the second drive unit 7A are each integrally disposed on a single support member 8A.

[0033] The first drive unit 6A is a so-called electric storage unit. The first drive unit 6A has a first motor 61A as the first drive unit and a rotational force transmission unit 62. The rotational force transmission unit 62 is composed of a reduction mechanism, a clutch mechanism, and the like. The rotational force transmission unit 62 transmits the rotational force of the first motor 61A to the fixed side shaft 3A, and rotates the first drive unit 6A, the second drive unit 7A, and the support member 8A around the storage axis V0A-V0A in the direction of the dashed arrow.

[0034] As a result, the first motor 61A of the first drive unit 6A rotates the mirror housing 4A (including the mirror 5A) about the storage axis V0A-V0A in the direction of the dashed arrow via the second drive unit 7A, the support member 8A and the pivot mechanism 9A.

[0035] The second drive unit 7A is a so-called power unit. The second drive unit 7A includes a first advancing / retracting rod 70A, a second advancing / retracting rod 71A, a second motor 72A as a second drive unit, a third motor 73A as a second drive unit, a first detector 74A, and a second detector 75A.

[0036] The first advancing / retracting rod 70A is attached to the second motor 72A via a rotational force conversion mechanism so that it can advance and retreat. That is, the first advancing / retracting rod 70A advances and retreats due to the rotational force of the second motor 72A. As a result, the second motor 72A of the second drive unit 7A rotates the mirror housing 4A (including the mirror 5A) around the second axis V2A-V2A in the direction of the solid arrow via the first advancing / retracting rod 70A and the pivot mechanism 9A. As shown in FIG. 3, the second axis V2A-V2A is an axis line connecting the second center point A3 as a support point of the spherical portion of the second advancing / retracting rod 71A and the center point A1 of the pivot mechanism 9A.

[0037] Similarly, the second advancing / retracting rod 71A is attached to the third motor 73A via a rotational force conversion mechanism so as to be capable of advancing and retracting. That is, the second advancing / retracting rod 71A advances and retreats due to the rotational force of the third motor 73A. As a result, the third motor 73A of the second drive unit 7A rotates the mirror housing 4A (including the mirror 5A) around the first axis V1A-V1A in the direction of the dashed arrow via the second advancing / retracting rod 71A and the pivot mechanism 9A. As shown in FIG. 2, the first axis V1A-V1A is an axis connecting the first center point A2 as a support point of the spherical portion of the first advancing / retracting rod 70A and the center point A1 of the pivot mechanism 9A.

[0038] Here, the driving speed of the first motor 61A is faster than the driving speeds of the second motor 72A and the third motor 73A.

[0039] The first detector 74A detects the forward and backward displacement of the first advancing and retracting rod 70A and outputs the detection result as a detection signal. As a result, the first detector 74A detects the rotational displacement of the mirror housing 4A caused by the second motor 72A via the first advancing and retracting rod 70A and the pivot mechanism 9A.

[0040] Similarly, the second detector 75A detects the forward and backward displacement of the second advancing and retracting rod 71A and outputs the detection result as a detection signal. As a result, the second detector 75A detects the rotational displacement of the mirror housing 4A caused by the third motor 73A via the second advancing and retracting rod 71A and the pivot mechanism 9A.

[0041] The first detection unit 74A and the second detection unit 75A are connected to a control unit (not shown). Each driver adjusts the angle of the mirror 5A to match his / her field of vision, and the adjustment result is stored in the control unit. Thus, each driver can operate the control unit to automatically adjust the angle of the mirror 5A to match his / her field of vision.

[0042] In this example, the support member 8A is composed of a first support part 81A and a second support part 82A that are integrally formed. The first support part 81A constitutes a casing for the first drive unit 6A. The first motor 61A is disposed in the first support part 81A. The second support part 82A constitutes a casing for the second drive unit 7A. The second motor 72A and the third motor 73A are disposed in the second support part 82A.

[0043] As a result, the first motor 61A, the second motor 72A, and the third motor 73A are each integrally disposed on the single support member 8A. As a result, the relative positional relationship between the first motor 61A, the second motor 72A, and the third motor 73A is invariant with respect to the rotation of the mirror housing 4A, supported by the single support member 8A. In other words, the relative positional relationship between the first motor 61A, the second motor 72A, and the third motor 73A is constant regardless of the movement of the mirror housing 4A.

[0044] The first support portion 81A and the second support portion 82A of the support member 8A may be separated from each other. That is, the first motor 61A may be disposed in the first support portion 81A, and the second motor 72A and the third motor 73A may be disposed in the second support portion 82A. Even in this case, the relative positional relationship between the first motor 61A, the second motor 72A, and the third motor 73A is unchanged by the first support portion 81A and the second support portion 82A against the rotation of the mirror housing 4A.

[0045] The pivot mechanism 9A is composed of a first pivot portion 91A and a second pivot portion 92A. The first pivot portion 91A is fixed to the support member 8A and has a spherical concave surface. The second pivot portion 92A is fixed to the mirror housing 4A via a bracket 93A and a screw 94A and has a spherical convex surface. The spherical convex surface of the second pivot portion 92A is rotatably fitted into the spherical concave surface of the first pivot portion 91A.

[0046] As a result, the mirror housing 4A (including the mirror 5A) on the second pivot portion 92A side can rotate about the center point A1 of the pivot mechanism 9A relative to the support member 8A (including the first drive unit 6A and the second drive unit 7A) on the first pivot portion 91A side.

[0047] This allows the mirror housing 4A (including the mirror 5A) to rotate about the first axis V1A-V1A and about the second axis V2A-V2A relative to the support member 8A (including the first drive unit 6A and the second drive unit 7A). The center point A1 of the pivot mechanism 9A is also the intersection of the first axis V1A-V1A and the second axis V2A-V2A.

[0048] The size of the opening 41A in the mirror housing 4A is set to a size that allows rotation of the mirror housing 4A by the second drive unit 7A. In other words, the size of the opening 41A is set to a size that prevents the periphery of the opening 41A in the mirror housing 4A from hitting the shaft 3A when the mirror housing 4A is rotated about the first axis V1A-V1A and about the second axis V2A-V2A by the second drive unit 7A.

[0049] In addition, the size of the opening 41A in the mirror housing 4A is set based on the distance between the intersection A1 of the first axis V1A-V1A and the second axis V2A-V2A and the storage axis V0A-V0A, and the diameter of the shaft 3A.

[0050] The storage axis V0A-V0A and the second axis V2A-V2A are in a parallel position as shown in Figures 1, 2, and 4. Also, the storage axis V0A-V0A and the first axis V1A-V1A are in a twisted position as shown in Figures 1, 2, and 4.

[0051] As shown in FIG. 2, the second drive unit 7A is disposed outside the vehicle relative to the first drive unit 6A.

[0052] (Description of Function of First Embodiment) The vehicle mirror device 1A according to the first embodiment is configured as described above, and its operation will be described below.

[0053] The first motor 61A of the first drive unit 6A is rotated. Then, the mirror housing 4A and the mirror 5A rotate around the storage axis V0A-V0A of the shaft 3A in the direction of the dashed arrow, i.e., in the front-rear direction of the vehicle, via the first drive unit 6A, the second drive unit 7A, the support member 8A, and the pivot mechanism 9A. As a result, the mirror housing 4A and the mirror 5A are deployed laterally relative to the vehicle when in use, and folded and stored vertically relative to the vehicle when not in use.

[0054] Also, the second motor 72A of the second drive unit 7A is rotated. Then, the first advancing / retracting rod 70A advances and retreats, and the mirror housing 4A and the mirror 5A rotate about the second axis V2A-V2A in the direction of the solid arrow, i.e., in the left-right direction of the vehicle, relative to the first drive unit 6A, the second drive unit 7A, and the support member 8A via the pivot mechanism 9A. This adjusts the left-right angle of the mirror 5A. At this time, the first detector 74A detects the left-right rotational displacement of the mirror housing 4A and outputs the detection result to the controller as a detection signal.

[0055] Furthermore, the third motor 73A of the second drive unit 7A is rotated. Then, the second advance / retract rod 71A advances / retracts, and the mirror housing 4A and the mirror 5A rotate around the first axis V1A-V1A in the direction of the dashed arrow, i.e., in the vertical direction of the vehicle, relative to the first drive unit 6A, the second drive unit 7A, and the support member 8A via the pivot mechanism 9A. This adjusts the vertical angle of the mirror 5A. At this time, the second detection unit 75A detects the vertical rotational displacement of the mirror housing 4A and outputs the detection result to the control unit as a detection signal.

[0056] This allows the angle of the mirror 5A to be adjusted so that the driver can easily see from the sides and rearward.

[0057] The drive speed of the first motor 61A is faster than the drive speeds of the second motor 72A and the third motor 73A. As a result, the storage operation can be performed faster than the angle adjustment operation, and the angle adjustment operation can be performed slower than the storage operation.

[0058] When an external force in the front-to-rear direction of the vehicle is applied to the mirror housing 4A during use, the clutch mechanism of the first drive unit 6A causes the mirror housing 4A and the mirror 5A to rotate around the storage axis V0A-V0A of the shaft 3A in the direction of the dashed arrow, i.e., in the front-to-rear direction of the vehicle. This makes it possible to buffer the external force applied to the components including the mirror housing 4A and the mirror 5A.

[0059] In particular, when an external force is applied from the front to the rear of the vehicle, the spherical convex surface of the front second pivot portion 92A abuts against the spherical concave surface of the rear first pivot portion 91A to support the load in the compression direction. Also, the first advancing / retracting rod 70A and the second advancing / retracting rod 71A of the second drive unit 7A are pressed in to absorb the impact. If the impact is larger than the impact that the first advancing / retracting rod 70A and the second advancing / retracting rod 71A can absorb, the larger impact is absorbed by the clutch mechanism of the first drive unit 6A.

[0060] (Explanation of Effects of the First Embodiment) The vehicle mirror device 1A according to the first embodiment has the above-mentioned configuration and functions, and the effects thereof will be described below.

[0061] The vehicle mirror device 1A according to the first embodiment has a simple configuration since it includes a mirror housing 4A, a mirror 5A, a first drive unit 6A, and a second drive unit 7A. As a result, the vehicle mirror device 1A according to the first embodiment can make the first drive unit 6A and the second drive unit 7A compact and integrate them.

[0062] In the vehicle mirror device 1A according to the first embodiment, the storage axis V0A-V0A, the first axis V1A-V1A, and the second axis V2A-V2A are in a twisted position, so that the rotation of the mirror housing 4A and the mirror 5A about the storage axis V0A-V0A, and the rotation of the mirror housing 4A and the mirror 5A about the first axis V1A-V1A and the second axis V2A-V2A can be performed independently. As a result, the vehicle mirror device 1A according to the first embodiment can perform the storage operation and the angle adjustment operation smoothly and independently.

[0063] In the vehicle mirror device 1A according to the first embodiment, as shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the storage axis V0A-V0A and the first axis V1A-V1A are in a twisted position. As a result, the vehicle mirror device 1A according to the first embodiment can independently rotate the mirror housing 4A and the mirror 5A about the storage axis V0A-V0A, and can independently rotate the mirror housing 4A and the mirror 5A about the first axis V1A-V1A and about the second axis V2A-V2A. This allows the vehicle mirror device 1A according to the first embodiment to smoothly and independently perform the storage operation and the angle adjustment operation.

[0064] In the vehicle mirror device 1A according to the first embodiment, as shown in Figs. 1, 2, and 4, the storage axis V0A-V0A and the second axis V2A-V2A are in a parallel position, and as shown in Figs. 1, 2, 3, and 4, the storage axis V0A-V0A and the first axis V1A-V1A are in a twisted position. As a result, the vehicle mirror device 1A according to the first embodiment can independently rotate the mirror housing 4A and the mirror 5A around the storage axis V0A-V0A, and rotate the mirror housing 4A and the mirror 5A around the first axis V1A-V1A and the second axis V2A-V2A. This allows the vehicle mirror device 1A according to the first embodiment to smoothly and independently perform the storage operation and the angle adjustment operation.

[0065] The vehicle mirror device 1A according to the first embodiment has a simple configuration since the first drive unit 6A has the first motor 61A, and the second drive unit 7A has the second motor 72A and the third motor 73A.

[0066] In the vehicle mirror device 1A of this embodiment 1, the relative positional relationship between the first motor 61A, the second motor 72A and the third motor 73A remains unchanged despite the rotation of the mirror housing 4A, so that the storage operation and the angle adjustment operation can each be performed independently.

[0067] In the vehicle mirror device 1A of this embodiment 1, the first motor 61A, the second motor 72A and the third motor 73A are installed on at least one support member 8A, so that the storage operation and the angle adjustment operation can be performed reliably and independently.

[0068] In the vehicle mirror device 1A of this embodiment 1, the driving speed of the first motor 61A is faster than the driving speeds of the second motor 72A and the third motor 73A, so that the storage operation can be performed faster than the angle adjustment operation, and the angle adjustment operation can be performed slower than the storage operation.

[0069] In the vehicle mirror device 1A of this embodiment 1, the shaft 3A constituting the storage axis V0A-V0A extends into and out of the storage space 40A through the opening 41A of the mirror housing 4A, so that the components can be arranged compactly.

[0070] In the vehicle mirror device 1A according to the first embodiment, the size of the opening 41A of the mirror housing 4A is set to a size that allows the second drive unit 7A to rotate the mirror housing 4A, so that when the second drive unit 7A rotates the mirror housing 4A around the first axis V1A-V1A and around the second axis V2A-V2A, the periphery of the opening 41A of the mirror housing 4A does not come into contact with the shaft 3A. As a result, the vehicle mirror device 1A according to the first embodiment does not apply a load to the components.

[0071] In the vehicle mirror device 1A of this embodiment 1, the size of the opening 41A in the mirror housing 4A is set based on the distance between the intersection A1 of the first axis V1A-V1A and the second axis V2A-V2A and the storage axis V0A-V0A, and the diameter of the shaft 3A, so that it is possible to reliably prevent the peripheral edge of the opening 41A in the mirror housing 4A from coming into contact with the shaft 3A.

[0072] In the vehicle mirror device 1A of this embodiment 1, the second drive unit 7A has a first detection section 74A that detects the rotational displacement of the mirror housing 4A caused by the second motor 72A and a second detection section 75A that detects the rotational displacement of the mirror housing 4A caused by the third motor 73A, so that the angle adjustment of the mirror 5A can be automated.

[0073] In the vehicle mirror device 1A according to the first embodiment, the pivot mechanism 9A is composed of a first pivot portion 91A fixed to the support member 8A and a second pivot portion 92A fixed to the mirror housing 4A. As a result, in the vehicle mirror device 1A according to the first embodiment, the mirror housing 4A (including the mirror 5A) on the second pivot portion 92A side can rotate around the center point A1 of the pivot mechanism 9A with respect to the support member 8A (including the first drive unit 6A and the second drive unit 7A) on the first pivot portion 91A side. As a result, the vehicle mirror device 1A according to the first embodiment can reduce the mass of the second pivot portion 92A and the mirror housing 4A (including the mirror 5A) on the movable side, and can suppress the influence of the vehicle vibration on the movable side mirror 5A.

[0074] In the vehicle mirror device 1A according to the first embodiment, the second drive unit 7A is disposed on the outside of the vehicle relative to the first drive unit 6A. As a result, the vehicle mirror device 1A according to the first embodiment can reduce the vertical dimensions of the mirror housing 4A and the mirror 5A, and accordingly the projected area of ​​the front of the mirror housing 4A and the mirror 5A can be reduced. As a result, the vehicle mirror device 1A according to the first embodiment can reduce air resistance, improving fuel efficiency. In addition, the vehicle mirror device 1A according to the first embodiment can be installed in a small sports car that does not suit a large door mirror device, and even if it is installed, the design of the small sports car is not impaired.

[0075] (Description of the configuration, operation, and effect of the second embodiment) Fig. 5 is a front view (view from the rear to the front of the vehicle) showing a vehicle mirror device according to a second embodiment of the present invention in a used state. In Fig. 5, the same reference numerals as those in Figs. 1 to 4 indicate the same components. The configuration of this second embodiment is a conceptual configuration, similar to the configuration of the first embodiment.

[0076] In the vehicle mirror device 100A of this embodiment 2, the base 2A and the mirror housing 4A are fitted together via fitting receiving portions 200A, 400A which are composed of spherical surfaces centered on the intersection A1 of the first axis V1A-V1A and the second axis V2A-V2A.

[0077] The fitting receiving portion 200A on the base 2A side forms a spherical concave surface. The fitting receiving portion 400A on the mirror housing 4A side forms a spherical convex surface with a radius R. The spherical concave surface of the fitting receiving portion 200A on the base 2A side and the spherical convex surface of the fitting receiving portion 400A on the mirror housing 4A side face each other. The gap between the spherical concave surface of the opposing surface of the fitting receiving portion 200A on the base 2A side and the spherical convex surface of the opposing surface of the fitting receiving portion 400A on the mirror housing 4A side is constant and is about 0.5 mm to about 5 mm in this example.

[0078] The vehicle mirror device 100A according to the second embodiment has the above-mentioned configuration, and therefore can achieve the same effects as those of the vehicle mirror device 1A according to the first embodiment.

[0079] In particular, in the vehicle mirror device 100A of this embodiment 2, the base 2A and the mirror housing 4A are engaged via the engaging receiving portions 200A, 400A which are composed of a spherical surface centered on the intersection A1 of the first axis V1A-V1A and the second axis V2A-V2A, so that the mirror housing 4A can be smoothly rotated relative to the base 2A.

[0080] Moreover, in the vehicle mirror device 100A of the second embodiment, the gap between the spherical convex fitting receiving portion 400A on the mirror housing 4A side is constant, so that the base 2A and the mirror housing 4A can be seen as one unit, which is aesthetically preferable.

[0081] The vehicle mirror device 100A according to the second embodiment includes a base 2A fixed to the vehicle body (door D), and the base 2A and the mirror housing 4A are fitted to each other via fitting receiving parts 200A and 400A formed of a spherical surface centered on the intersection point A1 between the first axis V1A-V1A and the second axis V2A-V2A, so that the mirror housing 4A can rotate smoothly around the first axis V1A-V1A and the second axis V2A-V2A. As a result, the vehicle mirror device 100A according to the second embodiment can use small motors with low output as the second motor 72A and the third motor 73A, and the manufacturing cost can be reduced accordingly.

[0082] (Description of the configuration of the third embodiment) 6 to 48 show a vehicle mirror device according to a third embodiment of the present invention.

[0098] A motor, a rotational force transmission mechanism, and other mechanisms are housed inside the gear case 60 and the cover 61. The gear case 60 and the cover 61 are made up of a gear case 60 and a cover 61. In this example, the gear case 60 is made of a resin having high rigidity (PA resin containing glass fiber). The gear case 60 is provided with a first fixing portion 601 and a second fixing portion 602. The first fixing portion 601 and the second fixing portion 602 are provided with screw holes into which the screws 73 are screwed.

[0099] The gear case 60 and the cover 61 are stored in the storage space 35 of the structure 34, and are assembled to the shaft 20 so as to be rotatable around a storage axis (third axis) V0 which is the center line of the shaft 20.

[0100] The storage unit 6 rotates the structure 34, i.e., the mirror assembly 3, between the use position (set position) A and the rear storage position P2 around the storage axis V0 relative to the fixed side shaft 20 and base 2, via the rotating side gear case 60 and cover 61 and the holding unit 7, to position it at the use position P1 or the rear storage position P2 (see Figure 10).

[0101] Stoppers 204 and 603 are provided on the shaft 20 and the gear case 60, respectively. The stoppers 204 and 603 stop the structure 34, i.e., the mirror assembly 3, at the use position P1 or the rear storage position P2.

[0102] In this example, the stoppers 204, 603 of the stopping mechanism for the use position P1 or the rear storage position P2 are provided between the base 2 (shaft 20) side and the storage unit 6 (gear case 60) side. The stopping mechanism may be provided inside the storage unit 6.

[0103] 10, the mirror assembly 3 can be rotated to a front storage position (forward tilted position) C in addition to the use position P1 or the rear storage position P2. A stop mechanism (not shown) is also provided to stop the mirror assembly 3 at the front storage position P3.

[0104] (Description of holding unit 7) The holding unit 7 is stored in the storage space 35. The holding unit 7 has a fixed side part 70, a movable side part 71, a washer 72, and a screw 73. The holding unit 7 holds the structure 34 of the mirror assembly 3 via the movable side part 71 and the washer 72 relative to the fixed side part 70 so as to be rotatable about a first axis V1 and a second axis V2.

[0105] The fixed side portion 70 is provided with a convex spherical pivot portion 700. The movable side portion 71 is provided with a concave spherical pivot portion 710. The concave spherical pivot portion 710 of the movable side portion 71 is attached to the convex spherical pivot portion 700 of the fixed side portion 70 so as to be rotatable about a first axis V1 and a second axis V2. The washer 72 is sandwiched between the convex spherical pivot portion 700 of the fixed side portion 70 and the concave spherical pivot portion 710 of the movable side portion 71.

[0106] (Explanation of 1st axis V1, 2nd axis V2, storage axis V0) In this example, the first axis V1 and the second axis V2 are orthogonal to each other as shown in Fig. 6. That is, the first axis V1 and the second axis V2 intersect perpendicularly (at a right angle). The intersection of the first axis V1 and the second axis V2 constitutes the holding center CH. The holding center CH is the center of the pivot portion of the fixed side part 70 and the pivot portion of the movable side part 71. In this example, the holding center CH is close to the storage axis V0.

[0107] In this example, the first axis V1 is in a skewed position with respect to the storage axis V0 as shown in Fig. 11. Also, the first axis V1 and the storage axis V0 intersect perpendicularly, i.e., vertically (at a right angle), when viewed from the front as shown in Fig. 6.

[0108] In this example, the second axis V2 is parallel to the storage axis V0 and is located on the rear side and outside of the vehicle, as shown in FIGS.

[0109] In this example, the first axis V1 and the second axis V2 intersect perpendicularly, but they may not intersect perpendicularly. In this case, the first axis V1 and the storage axis V0 do not intersect perpendicularly in a front view, or the second axis V2 is not parallel to the storage axis V0.

[0110] In this example, the holding center CH is close to the storage axis V0, but it may be located on the storage axis V0. In this case, the second axis V2 and the storage axis V0 coincide. In other words, the second axis V2 and the storage axis V0 are one axis.

[0111] Furthermore, in this example, the first axis V1 is in a skewed position with respect to the storage axis V0, but may intersect with the storage axis V0. In this case, the first axis V1 and the storage axis V0 are in a state where they intersect perpendicularly, or in a state where they intersect but not perpendicularly.

One end 813 of the first rod portion 811 and one end 823 serving as a support point of the second rod portion 821 are attached to the movable side portion 71 by clips 812 and 822, respectively.

[0142] As shown in Figures 14 and 21, in the opposing surfaces of the second main body part 820 of the second mirror angle adjustment unit 82 and the mirror 31 of the structure 34 that face each other in the direction around the second axis V2, the opposing surface 824 of the second main body part 820 is inclined so that the distance between it and the opposing surface of the mirror 31 of the structure 34 located in the neutral position (the position shown in Figures 21(B) and 22) becomes longer from the side closer to the second axis V2 (the left side in Figures 14 and 21) to the side farther from the second axis V2 (the right side in Figures 14 and 21).

[0143] Although not shown in Figure 21, as shown in Figure 14, in the opposing surfaces of the first main body part 810 of the first mirror angle adjustment unit 81 and the mirror 31 of the structure 34 that face each other in the direction around the first axis V1, the opposing surface 814 of the first main body part 810 is inclined so that the distance between it and the opposing surface of the mirror 31 of the structure 34 located in the neutral position (position shown in Figure 25) becomes longer from the side closer to the first axis V1 (lower side in Figure 14) to the side farther from the first axis V1 (upper side in Figure 14).

[0144] The first rod portion 811 has an arc shape centered on the holding center CH, as shown in Fig. 40. As a result, one end 813 of the first rod portion 811 advances and retreats in an arc direction centered on the holding center CH on a first plane S1 that includes the second axis V2 and is perpendicular to the first axis V1, as shown by the arc shape solid arrow in Fig. 42, by driving the first main body portion 810. This adjusts the angle of the mirror surface about the first axis V1.

[0145] The second rod portion 821 has an arc shape centered on the holding center CH, as shown in Fig. 21 and Fig. 40. As a result, one end 823 of the second rod portion 821 advances and retreats in an arc direction centered on the holding center CH on a second plane S2 that includes the first axis V1 and is perpendicular to the second axis V2, as shown by the arc shape solid arrow in Fig. 42, by driving the second main body portion 820. This adjusts the angle of the mirror surface about the second axis V2.

[0146] The distance between one end 813 of the first rod portion 811 and the holding center CH, and the distance between one end 823 of the second rod portion 821 and the holding center CH are farther apart than at least one of the distance between the nearby storage axis V0 and the holding center CH or the distance between the nearby holding center CH and the center of gravity CG.

[0147] Here, the holding center CH is close to the center of gravity CG of the structure 34 and the movable portion 71. Note that the holding center CH and the center of gravity CG may coincide with each other.

[0148] (CG explanation of center of gravity) The center of gravity CG is the center of gravity of a movable part that rotates around a first axis V1 and a second axis V2 relative to a fixed part in the mirror assembly 3. The movable part of the mirror assembly 3 has a structure 34 (comprised of a mirror housing 30 (comprised of a main body part 32 and a ring part 33) and a mirror 31), a movable side part 71 of the holding unit 7 (comprised of a first movable side bracket 76 and a second movable side bracket 77), and a screw 73.

[0149] The fixed portion of the mirror assembly 3 includes a storage unit 6, a fixed side portion 70 of the holding unit 7 (consisting of a first fixed side bracket 74 and a second fixed side bracket 75), a first mirror angle adjustment unit 81, a second mirror angle adjustment unit 82, a camera 5, and a harness 50.

[0150] Further, the entire mirror assembly 3 except for the shaft 20 constitutes a movable part side that rotates around a storage axis V0 relative to the fixed part side of the shaft 20 and the base 2.

[0151] (Explanation of Camera 5 and Harness 50) As shown in FIG. 43, the camera 5 has a main body portion 51, a lens portion 52, and an attachment portion 53.

[0152] As shown in FIG. 43, the harness 50 includes a camera harness 54, an electrical harness 55, a first mirror angle adjustment harness 56, and a second mirror angle adjustment harness 57.

[0153] The camera 5 is electrically connected to the end of the camera harness 54. As a result, the camera 5 and the harness 50 form an integrated assembly. The end of the electrical harness 55 is electrically connected to an electrical connector 550. The end of the first mirror angle adjustment harness 56 is electrically connected to a first mirror angle adjustment connector 560. The end of the second mirror angle adjustment harness 57 is electrically connected to a second mirror angle adjustment connector 570.

[0154] (Explanation of First Rotation Range Restriction Unit 91 and Second Rotation Range Restriction Unit 92) As shown in Figs. 22 to 27, the first rotation range restricting portion 91 and the second rotation range restricting portion 92 are provided on the fixed side portion 70 and the movable side portion 71, respectively.

[0155] The first rotation range restricting portion 91 restricts the range of rotation of the structure 34 around the first axis V1 (see FIGS. 26 and 27). The first rotation range restricting portion 91 has a first stopper 901 and a second stopper 902 provided on the fixed side portion 70 and the movable side portion 71, respectively.

[0156] The second rotation range restricting portion 92 restricts the range of rotation of the structure 34 around the second axis V2 (see FIGS. 23 and 24). The second rotation range restricting portion 92 has a first stopper 901, a second stopper 902, a third stopper 903, a fourth stopper 904, a fifth stopper 905, and a sixth stopper 906 provided on the fixed side portion 70 and the movable side portion 71, respectively.

[0157] The first stopper 901 and the second stopper 902 serve as both the first rotation range restricting portion 91 and the second rotation range restricting portion 92. The third stopper 903, the fourth stopper 904, the fifth stopper 905, and the sixth stopper 906 are dedicated to the second rotation range restricting portion 92.

[0158] 31, the first stopper 901 of the fixed side part 70 is made of a convex part (pin structure) provided in the center of the convex spherical pivot part 700 of the third fixed part 743 of the first fixed side bracket 74. The first stopper 901 of the movable side part 71 is made of the inner peripheral surface of a circular through hole provided in the center of the concave spherical pivot part 710 of the third attachment part 763 of the first movable side bracket 76, as shown in FIGS.

[0159] As shown in Fig. 33, the second stopper 902 of the fixed side part 70 is made up of the inner peripheral surface of a circular recess provided in the center of the convex spherical pivot part 700 of the first fixed part 751 of the second fixed side bracket 75. As shown in Fig. 39, the second stopper 902 of the movable side part 71 is made up of the outer peripheral surface of a circular protrusion provided in the center of the concave spherical pivot part 710 of the second movable side bracket 77.

[0160] 31, the third stopper 903 of the fixed side part 70 is formed from one end surface of the recess 747 of the convex spherical pivot part 700 of the first fixed side bracket 74. The third stopper 903 of the movable side part 71 is formed from one end surface of the convex part 766 of the first movable side bracket 76 as shown in FIGS.

[0161] 31, the fourth stopper 904 of the fixed side part 70 is made of a convex part (pin structure) provided on a part of the third fixed part 743 of the first fixed side bracket 74 on the second fixed part 742 side. The fourth stopper 904 of the movable side part 71 is made of a surface (wall surface) of a part between the third attachment part 763 and the second attachment part 762 of the first movable side bracket 76 as shown in FIGS. 36 and 37.

[0162] 33 and 34, the fifth stopper 905 of the fixed-side part 70 is formed from one end surface of the recess 755 of the convex spherical pivot part 700 of the second fixed-side bracket 75. The fifth stopper 905 of the movable-side part 71 is formed from one end surface of the convex part 770 of the second movable-side bracket 77 as shown in FIG.

[0163] 33 and 34, the sixth stopper 906 of the fixed side part 70 is made of a protrusion (pin structure) provided in a portion between the first fixed part 751 and the second fixed part 752 of the second fixed side bracket 75. As shown in Fig. 39, the sixth stopper 906 of the movable side part 71 is made of one surface of the mounting part of the second movable side bracket 77 on the outer side of the vehicle (the right side in Fig. 39).

[0164] Since the mirror angle adjustment may be performed manually, a force larger than the electric force of the first mirror angle adjustment unit 81 and the second mirror angle adjustment unit 82 may act on the first rotation range regulating part 91 and the second rotation range regulating part 92. Furthermore, when the mirror assembly 3 is manually rotated to the rear storage position P2 or the front storage position P3, a force always acts on the first rotation range regulating part 91 and the second rotation range regulating part 92.

[0165] For this reason, it is preferable that the first stopper 901, the second stopper 902, the third stopper 903, the fourth stopper 904, the fifth stopper 905 and the sixth stopper 906 of the first rotation range regulating portion 91 and the second rotation range regulating portion 92 have a sturdy structure.

[0166] (Explanation of Spacer 4) In this example, the spacer 4 is made of POM resin. The spacer 4 is interposed between the base 2 and the mirror housing 30, as shown in FIGS.

[0167] The spacer 4 rotates together with the structure 34 relative to the base 2 when the structure 34 rotates about the storage axis V0 and when the structure 34 rotates about the second axis V2. The spacer 4 does not rotate together with the structure 34 and is in a stationary state together with the base 2 when the structure 34 rotates about the first axis V1.

[0168] 44, the spacer 4 has a cylindrical shape with a low height (short axial length). A circular insertion hole 40 is provided in the center of the spacer 4. The insertion hole 40 of the spacer 4 and the insertion hole 36 of the mirror housing 30 are aligned with each other.

[0169] The central axis of the spacer 4 coincides with or nearly coincides with the second axis V2. The center of the insertion hole 40 of the spacer 4 coincides with or nearly coincides with the storage axis V0. Therefore, in a plan view of the spacer 4 (viewed from above), the outline circle of the spacer 4 and the circle of the insertion hole 40 are misaligned with each other.

[0170] The spacer 4 has a step surface 43 formed between the upper portion 41 and the lower portion 42. The upper portion 41 has a larger diameter than the lower portion 42. The lower portion 42 has a convex shape that protrudes downward from the step surface 43, and is fitted into the concave spacer support portion 25 of the base 2 so as to be rotatable around the storage axis V0 and the second axis V2.

[0171] The edge of the insertion hole 36 of the structure 34 and the edge of the insertion hole 40 of the spacer 4 are provided with mating surfaces 38, 44, respectively (see Figs. 17 to 19). The mating surface 38 of the structure 34 and the mating surface 44 of the spacer 4 are formed of a surface of revolution with the first axis V1 as the center line, in this example, a spherical surface.

[0172] As a result, the edge of the insertion hole 36 of the structure 34 forms a spherical convex shape following the spherical mating surface 38. On the other hand, the edge of the insertion hole 40 of the spacer 4 forms a spherical concave shape following the spherical mating surface 44.

[0173] The mating surface 38 of the structure 34 and the mating surface 44 of the spacer 4 may be other than the spherical surface in this example. For example, as shown in Fig. 45, they may be a barrel surface of a surface of rotation with the first axis V1 as a center line, or as shown in Fig. 46, they may be a cylindrical surface of a surface of rotation with the first axis V1 as a center line.

[0174] The mating surface 38 of the structure 34 and the mating surface 44 of the spacer 4 are provided with engagement portions 39, 45, respectively, in the rotational direction about the first axis V1 (see FIGS. 18, 19, 45, and 46). In this example, the engagement portion 39 of the structure 34 is concave. On the other hand, the engagement portion 45 of the spacer 4 is convex. Note that the engagement portion 39 of the structure 34 may be convex, and the engagement portion 45 of the spacer 4 may be concave.

[0175] As shown in Figure 19, the engagement portions 39, 45 engage with each other when the structure 34 rotates around the storage axis V0 and when it rotates around the second axis V2, and the spacer 4 rotates together with the structure 34 relative to the base 2 (see the arc-shaped solid arrow and dashed arrow in Figure 19).

[0176] Furthermore, as shown in FIG. 19, when the structure 34 rotates around the first axis V1, the engagement portions 39, 45 slide relative to each other (see the straight dashed arrow in FIG. 19), so that the spacer 4 does not rotate together with the structure 34 but remains stationary together with the base 2.

[0177] Among the shaping surfaces (design surfaces, external surfaces) of the structure 34, shaping surface S3 (see Figure 47) including the boundary with the mating surface 38 of the structure 34, and surface S4 (see Figure 47) of the mating surface 44 of the spacer 4 including the contour of the edge facing the shaping surface S3, are composed of a surface extending perpendicularly to the plane S5 of the curved straight line L on the plane S5 including the storage axis V0 and the second axis V2, as shown in Figure 48.

[0178] In this example, the curved straight line L is extended perpendicular to the plane S5 to form the printing surface S3 of the structure 34 and the surface S4 of the spacer 4, but a straight line, curve, or free curve other than the curved straight line L may be extended perpendicular to the plane S5 to form the printing surface S3 of the structure 34 and the surface S4 of the spacer 4.

[0179] The stepped surface 43 of the spacer 4 faces the lower side of the vehicle. Therefore, the stepped surface 43 of the spacer 4 is placed on the upper surface of the attachment portion 22 of the base 2 (the surface facing the structure 34).

[0180] An outer peripheral wall portion (outer peripheral edge portion) of the upper portion 41 of the spacer 4 is a flange portion having a flange shape. The flange portion (upper portion 41) is disposed between the opposing surface of the mounting portion 22 of the base 2 and the mating surface 38 of the structure 34. The flange portion (upper portion 41) has a size sufficient to cover the recessed opening of the spacer support portion 25 even when the spacer 4 and the structure 34 rotate together around the storage axis V0 and the second axis V2, as shown in Figs. 17 and 20.

[0181] (Description of the assembly process of the door mirror device 1) The assembly process of the door mirror device 1 will be described below.

[0182] The third fixing portion 743 of the first fixed side bracket 74 is attached and fixed to the first fixing portion 601 of the storage unit 6 with the screw 73. Also, the first fixing portion 751 of the second fixed side bracket 75 is attached and fixed to the second fixing portion 602 of the storage unit 6 with the screw 73.

[0183] At this time, the fitting convex portion of the third mounting portion 746 of the first fixed-side bracket 74 is fitted into the fitting hole of the boss portion of the first mounting portion 753 of the second fixed-side bracket 75. In addition, the fitting convex portion of the second mounting portion 754 of the second fixed-side bracket 75 is fitted into the fitting hole of the boss portion of the second mounting portion 745 of the first fixed-side bracket 74.

[0184] As a result, the holding center CH, which is the center of the convex spherical pivot part 700 of the first fixed side bracket 74 and the convex spherical pivot part 700 of the second fixed side bracket 75, is fixed to the storage unit 6. It should be noted that in this example, the holding center CH is not positioned on the storage axis V0, which is the rotation center line of the storage unit 6.

[0185] The mounting portion 53 of the camera 5 is attached and fixed to the first mounting portion 744 of the first fixed side bracket 74 with the screw 73. The harness 50 integrated with the camera 5 is inserted into the harness insertion hole 202 of the shaft 20 of the storage unit 6. The electrical connector 550 of the electrical harness 55 in the harness 50 is electrically connected to the storage unit 6.

[0186] The first main body 810 of the first mirror surface angle adjustment unit 81 is attached and fixed to the first fixing portion 741 of the first fixed side bracket 74 with the screw 73. Similarly, the second main body 820 of the second mirror surface angle adjustment unit 82 is attached and fixed to the second fixing portion 742 of the first fixed side bracket 74 with the screw 73.

[0187] The washer 72 is placed from the outside onto the convex spherical pivot portion 700 of the first fixed side bracket 74 and the convex spherical pivot portion 700 of the second fixed side bracket 75. At this time, the first stopper 901 of the first fixed side bracket 74 is positioned in the first through hole 721 of the washer 72. The second stopper 902 of the second fixed side bracket 75 faces the second through hole 722 of the washer 72. The recess 747 of the first fixed side bracket 74 and the recess 755 of the second fixed side bracket 75 face the elongated hole 723 of the washer 72.

[0188] This forms a fixed portion of the mirror assembly 3, which has a storage unit 6 having a shaft 20, a fixed side portion 70 of the holding unit 7 (consisting of a first fixed side bracket 74 and a second fixed side bracket 75), a first mirror angle adjustment unit 81, a second mirror angle adjustment unit 82, a camera 5, and a harness 50, as shown in Figure 16.

[0189] The concave spherical pivot portion 710 of the first movable bracket 76 is placed over the convex spherical pivot portion 700 of the first fixed bracket 74 from the outside with the washer 72 sandwiched between them. At the same time, the convex portion 766 of the concave spherical pivot portion 710 of the first movable bracket 76 is fitted into the concave portion 747 of the convex spherical pivot portion 700 of the first fixed bracket 74 through the long hole 723 of the washer 72. At this time, the first stopper 901 of the first fixed bracket 74 is positioned inside the first stopper 901 of the first movable bracket 76 through the first through hole 721 of the washer 72.

[0190] Furthermore, the concave spherical pivot portion 710 of the second movable side bracket 77 is placed over the convex spherical pivot portion 700 of the second fixed side bracket 75 from the outside with the washer 72 sandwiched therebetween. At the same time, the convex portion 770 of the concave spherical pivot portion 710 of the second movable side bracket 77 is fitted into the concave portion 755 of the convex spherical pivot portion 700 of the second fixed side bracket 75 through the long hole 723 of the washer 72. At this time, the second stopper 902 of the second movable side bracket 77 is positioned inside the second stopper 902 of the second fixed side bracket 75 through the second through hole 722 of the washer 72.

[0191] The flange of one of the fourth mounting portions 764 of the first movable-side bracket 76 is aligned with the flange of one of the mounting portions 771 of the second movable-side bracket 77. In addition, the convex portion of the other of the fourth mounting portions 764 of the first movable-side bracket 76 is fitted into the boss portion of the other of the mounting portions 771 of the second movable-side bracket 77. The first movable-side bracket 76 and the second movable-side bracket 77 are assembled together by the screw 73, and are also assembled to the first fixed-side bracket 74 and the second fixed-side bracket 75 of the fixed portion of the mirror assembly 3 so as to be rotatable about the holding center CH.

[0192] The first mounting portion 761 of the first movable-side bracket 76 is attached to one end 813 of the first rod portion 811 of the first mirror surface angle adjustment unit 81 by a clip 812 so as to be rotatable about the second axis V2. Moreover, the second mounting portion 762 of the first movable-side bracket 76 is attached to one end 823 of the second rod portion 821 of the second mirror surface angle adjustment unit 82 by a clip 822 so as to be rotatable about the first axis V1.

[0193] The fifth attachment portion 765 of the first movable side bracket 76, which is integrally assembled to the fixed portion of the mirror assembly 3, is assembled to the attachment portion 300 of the main body portion 32 of the mirror housing 30 with the screw 73. At this time, the engaging portion of the first movable side bracket 76 and the engaging portion of the main body portion 32 engage with each other in the direction around the first axis V1, and also engage with each other in the direction around the second axis V2.

[0194] The edges of the mirror 31 and the ring portion 33 are fitted into the edges of the opening of the main body portion 32 and fixed together. This allows the mirror housing 30 (i.e., the main body portion 32 and the ring portion 33) and the mirror 31 to be assembled into an integrated structure 34, and the mirror assembly 3 is assembled.

[0195] The mating surface 38 of the mirror housing 30 is aligned with the mating surface 44 of the spacer 4, and the engagement portion 39 of the mirror housing 30 is engaged with the engagement portion 45 of the spacer 4. The lower portion 42 of the spacer 4 is fitted into the recess of the spacer support portion 25 of the base 2, and the step surface 43 of the spacer 4 is placed on the upper surface of the spacer support portion 25 of the base 2.

[0196] As a result, the mirror assembly 3 is placed on the base 2 via the spacer 4. At this time, the flange portion of the upper portion 41 of the spacer 4 is positioned between the mating surface 38 of the mirror housing 30 and the upper surface of the spacer support portion 25 of the base 2, as shown in FIG.

[0197] Further, the shaft 20 and the shaft fixing portion 24 are inserted into the storage space 35 through the insertion hole 40 of the spacer 4 and through the insertion hole 36 of the mirror housing 30. Note that the illustration of the shaft 20 is omitted in Fig. 17. Also, only the shaft 20 may be inserted without the shaft fixing portion 24 being inserted. In other words, it is sufficient that at least the shaft 20 is inserted into the storage space 35 through the insertion hole 40 of the spacer 4 and through the insertion hole 36 of the mirror housing 30.

[0198] The fixing portion 200 of the shaft 20 on the mirror assembly 3 side is attached and fixed to the shaft fixing portion 24 of the mounting portion 22 of the base 2 with a screw 27. The cover portion 23 is assembled to the mounting portion 22. This completes the assembly of the door mirror device 1.

[0199] (Explanation of the Function of the Third Embodiment) The door mirror device 1 according to the third embodiment is configured as described above, and its operation will be described below.

[0200] (Explanation of the neutral position of the mirror surface) The mirror surface, which is the reflective surface of the mirror 31, is in the neutral position when it is located at the positions shown in Figures 21(B), 22, and 25. Also, when the structure 34 of the mirror assembly 3 is located at the position shown by the solid lines in Figures 11 and 12, the mirror surface is in the neutral position.

[0201] (Adjusting the angle of the mirror surface horizontally (front-back, left-right)) The structure 34 is rotated horizontally (in the direction of the solid arc arrow in Figures 23 and 24) around the second axis V2 relative to the base 2, either electrically by driving the second mirror angle adjustment unit 82 with a remote control, or manually.

[0202] For example, as shown in Figures 21(A) and 23, when the structure 34 is rotated forward (to the left; counterclockwise when viewed from above), the mirror surface faces outward. Also, as shown in Figures 21(C) and 24, when the structure 34 is rotated backward (to the right; clockwise when viewed from above), the mirror surface faces inward. This adjusts the horizontal angle of the mirror surface, as shown in Figure 11.

[0203] At this time, due to engagement between the engagement portion 39 of the mirror housing 30 of the structure 34 and the engagement portion 45 of the spacer 4, the spacer 4 rotates horizontally around the second axis V2 relative to the base 2 together with the structure 34 (see the dashed arc arrow in Figure 19), as shown by the solid arc arrow in Figures 19 and 20.

[0204] At this time, the movable portion 71 (structure 34 side) of the holding unit 7 rotates together with the washer 72 horizontally about the second axis V2 relative to the fixed portion 70 (base 2 side) of the holding unit 7.

[0205] When the structure 34 rotates around the second axis V2 to a predetermined angle, the rotation of the structure 34 is restricted by the operation of the first stopper 901, the second stopper 902, the third stopper 903, the fourth stopper 904, the fifth stopper 905, and the sixth stopper 906 of the second rotation range restricting portion 92, as shown in Fig. 23 and Fig. 24. In this example, the predetermined angle is about 10° in the front-rear direction from the neutral position. Note that this predetermined angle is not particularly limited.

[0206] (Adjusting the vertical (up and down) angle of the mirror surface) The structure 34 is rotated vertically (in the direction of the solid arc arrow in Figures 26 and 27) around the first axis V1 relative to the base 2, either electrically by driving the first mirror angle adjustment unit 81 with a remote control, or manually.

[0207] For example, as shown in Fig. 26, when the structure 34 is rotated upward (counterclockwise when viewed from the left side), the mirror surface faces upward. Also, as shown in Fig. 27, when the structure 34 is rotated downward (clockwise when viewed from the left side), the mirror surface faces downward. This adjusts the vertical angle of the mirror surface as shown in Fig. 12.

[0208] At this time, the spacer 4 does not rotate together with the structure 34, and is at a standstill together with the base 2. That is, only the structure 34 rotates vertically around the first axis V1 relative to the spacer 4 and the base 2 (see the straight dashed arrow in FIG. 19).

[0209] At this time, the movable portion 71 (structure 34 side) of the holding unit 7 rotates vertically together with the washer 72 about the first axis V1 relative to the fixed portion 70 (base 2 side) of the holding unit 7.

[0210] When the structure 34 rotates around the first axis V1 to a predetermined angle, the rotation of the structure 34 is restricted by the operation of the first stopper 901 and the second stopper 902 of the first rotation range restricting portion 91, as shown in Fig. 26 and Fig. 27. In this example, the predetermined angle is about 10° in both the up and down directions from the neutral position. Note that this predetermined angle is not particularly limited.

[0211] Here, in the case where the first mirror angle adjustment unit 81 and the second mirror angle adjustment unit 82 are electrically driven, the first rod portion 811 and the second rod portion 821 advance and retreat by driving the first main body portion 810 and the second main body portion 820, and rotate the structure 34 via the movable side portion 71. In addition, in the case where they are manually driven, the clutch mechanism of the first main body portion 810 and the clutch mechanism of the second main body portion 820 are disengaged in conjunction with the rotation of the structure 34, and the first rod portion 811 and the second rod portion 821 advance and retreat following the rotation of the structure 34.

[0212] As described above, the door mirror device 1 according to the third embodiment has a remote control mirror surface adjustment function for adjusting the angle of the mirror surface by a remote control.

[0213] (Explanation of the use position P1, rear storage position P2, and front storage position P3 of the mirror assembly 3) 10 indicates the mirror assembly 3 located at the use position P1, and the two-dot chain line in Fig. 10 indicates the mirror assembly 3 located at the rear storage position P2 or the front storage position P3.

[0214] (Explanation of storing and returning mirror assembly 3) 10, the storage unit 6 is driven to electrically rotate the mirror assembly 3 located at the use position P1 around the storage axis V0 in a clockwise direction as viewed from above relative to the base 2. Then, the mirror assembly 3 rotates and is stored at the rear storage position P2.

[0215] In addition, the storage unit 6 is driven to electrically rotate the mirror assembly 3 located at the rear storage position P2 around the storage axis V0 in the counterclockwise direction as viewed from above relative to the base 2. Then, the mirror assembly 3 rotates and returns to the use position P1.

[0216] When the mirror assembly 3 is located at the use position P1 or the rear storage position P2, the stopper 204, 603 of the stopping mechanism is actuated. This stops the rotation of the mirror assembly 3, and the mirror assembly 3 is located at the use position P1 or the rear storage position P2.

[0217] In this manner, the door mirror device 1 according to the third embodiment has an electric storage function for electrically storing and returning the mirror assembly 3.

[0218] Furthermore, the mirror assembly 3 located at the use position P1 is manually rotated counterclockwise as viewed from above about the storage axis V0 relative to the base 2. Then, the clutch mechanism of the rotational force transmission mechanism of the storage unit 6 is disengaged, and the mirror assembly 3 rotates and is stored at the front storage position P3.

[0219] Furthermore, the mirror assembly 3 located at the front storage position P3 is manually rotated clockwise around the storage axis V0 relative to the base 2 as viewed from above. Then, the mirror assembly 3 rotates and returns to the use position P1. At this time, the clutch mechanism, which was in the disengaged state, becomes in the engaged state.

[0220] When the mirror assembly 3 is located at the use position P1 or the front storage position P3, the stopper of the stopping mechanism is actuated, whereby the rotation of the mirror assembly 3 is stopped and the mirror assembly 3 is located at the use position P1 or the front storage position P3.

[0221] Furthermore, when an external force is applied to the mirror assembly 3 located at the use position P1, the mirror assembly 3 rotates around the storage axis V0 from the use position P1 to the rear storage position P2 or the front storage position P3 due to the buffering effect.

[0222] When the mirror assembly 3 rotates around the storage axis V0, due to engagement between the engagement portion 39 of the mirror housing 30 of the structure 34 and the engagement portion 45 of the spacer 4, the spacer 4 rotates around the storage axis V0 together with the mirror assembly 3 (see the dashed arc arrow in Figure 19) relative to the base 2, as shown by the solid arc arrow in Figures 19 and 20.

[0223] At this time, the storage axis V0 and the second axis V2 are misaligned. As a result, as shown in Fig. 17, the gap (rotation gap) between the inner peripheral wall surface of the circular recessed opening of the spacer support part 25 of the base 2 (see the large circle centered on the second axis V2 shown by the dashed line in Fig. 20) and the outer peripheral wall surface of the cylindrical lower part 42 of the spacer 4 that fits into the circular recessed opening of the spacer support part 25 is not constant.

[0224] 17 and 20, the flange portion of the upper portion 41 of the spacer 4 has a size sufficient to cover the recessed opening of the spacer support portion 25 even when the spacer 4 and the structure 34 rotate together around the storage axis V0 and the second axis V2. Therefore, the circular recessed opening of the spacer support portion 25 of the base 2 is covered and hidden by the flange portion of the upper portion 41 of the spacer 4 and cannot be seen from the outside.

[0225] (Explanation of Effects of the Third Embodiment) The door mirror device 1 according to the third embodiment has the above-mentioned configuration and functions, and the effects thereof will be described below.

[0226] In the door mirror device 1 according to the third embodiment, the holding center CH, which is the intersection of the first axis V1 and the second axis V2, is close to the storage axis V0, as shown in Fig. 6. As a result, the door mirror device 1 according to the third embodiment can reduce the projected area of ​​the front surface (front face) of the structure 34 (mirror housing 30 and mirror 31) of the mirror assembly 3, as compared with the mirror assembly 3A1 of an existing door mirror device (for example, the door mirror device of Patent Document 1), as shown in Figs. 7 and 8.

[0227] 7 and 8, the structure 34 of the mirror assembly 3 of the door mirror device 1 according to the third embodiment is indicated by a solid line, while the mirror assembly 3A1 of an existing door mirror device (for example, the door mirror device of Patent Document 1) is indicated by a two-dot chain line.

[0228] In the door mirror device 1 according to the third embodiment, the projected area of ​​the front surface (front face) of the structure 34 of the mirror assembly 3 can be made small, so that air resistance can be reduced, leading to improved fuel efficiency.

[0229] Furthermore, even though the door mirror device 1 according to the third embodiment has a remote control mirror surface adjustment mechanism and an electric storage mechanism, it is possible to reduce the projected area of ​​the front (front face) of the structure 34 of the mirror assembly 3. As a result, the door mirror device 1 according to the third embodiment can be installed in a small sports car on which a large door mirror device does not suit, and even if installed, the design of the small sports car is not impaired.

[0230] Furthermore, by using the storage unit 6, the door mirror device 1 of this embodiment 3 does not require the addition of a memory circuit or the like for returning the mirror assembly 3 to the usage position P1. Moreover, since the mirror assembly 3 is automatically returned to the usage position P1 and is fixed with high rigidity, there is little shaking of the mirror surface while driving.

[0231] Furthermore, in the door mirror device 1 of this embodiment 3, the holding center CH, which is the operating center of the mirror surface, is positioned within the structure 34 of the mirror assembly 3, so that the holding center CH and the mirror surface can be brought closer together, the amount of shaking of the mirror surface can be reduced, and visibility is improved.

[0232] Furthermore, in the door mirror device 1 of this embodiment 3, the first mirror angle adjustment unit 81 and the second mirror angle adjustment unit 82 of the remote control mirror adjustment mechanism and the storage unit 6 of the electric storage mechanism are configured separately, so that the operation speed of the remote control mirror adjustment and the operation speed of the electric storage can be controlled separately, eliminating the need for an operation speed adjustment circuit, etc., and thereby enabling the number of components to be reduced.

[0233] In particular, in the door mirror device 1 of this embodiment 3, the first mirror angle adjustment unit 81 is positioned on the upper side of the vehicle relative to the storage unit 6, and the second mirror angle adjustment unit 82 is positioned on the outside of the vehicle relative to the storage unit 6, so that the projection area of ​​the front (front face) of the structure 34 of the mirror assembly 3 can be further reduced.

[0234] In the door mirror device 1 of this embodiment 3, in the opposing surfaces of the first main body part 810 of the first mirror angle adjustment unit 81 and the structure 34 that face each other in the direction around the first axis V1, the opposing surface 814 of the first main body part 810 is inclined so that the distance between the opposing surface of the structure 34 located in the neutral position (the inner surface of the mirror 31, i.e., the surface opposite the reflective surface of the mirror 31) becomes longer from the side closer to the first axis V1 to the side farther from the first axis V1; and similarly, in the opposing surfaces of the second main body part 820 of the second mirror angle adjustment unit 82 and the structure 34 that face each other in the direction around the second axis V2, the opposing surface 824 of the second main body part 820 is inclined so that the distance between the opposing surface of the structure 34 (see Figure 21 (B)) located in the neutral position becomes longer from the side closer to the second axis V2 to the side farther from the second axis V2. As a result, even if the distance between the opposing surface 814 of the first main body portion 810 and the opposing surface 824 of the second main body portion 820 and the opposing surface of the structure 34 is reduced, the door mirror device 1 according to the third embodiment can prevent the opposing surface of the structure 34 from hitting the opposing surface 814 of the first main body portion 810 and the opposing surface 824 of the second main body portion 820 due to rotation of the structure 34. This allows the door mirror device 1 according to the third embodiment to reduce the size of the storage space 35 for the structure 34.

[0235] 21 is a diagram showing the relative positional relationship between the opposing surface 824 of the second main body part 820 of the second mirror angle adjustment unit 82 that rotates around the second axis V2 and the opposing surface of the structure 34. However, by turning the left and right of FIG. 21 up and down, it can be considered as the relative positional relationship between the opposing surface 814 of the first main body part 810 of the first mirror angle adjustment unit 81 that rotates around the first axis V1 and the opposing surface of the structure 34.

[0236] The door mirror device 1 according to the third embodiment is provided with a first rotation range regulating portion 91 that regulates the range in which the structure 34 rotates around the first axis V1 and a second rotation range regulating portion 92 that regulates the range in which the structure 34 rotates around the second axis V2, respectively, on the fixed side portion 70 and the movable side portion 71, so that the rotation range of the structure 34 can be regulated. As a result, the door mirror device 1 according to the third embodiment can prevent the opposing surface of the structure 34 from hitting the opposing surface 814 of the first main body portion 810 and the opposing surface 824 of the second main body portion 820 due to the rotation of the structure 34, even if the distance between the opposing surface 814 of the first main body portion 810 and the opposing surface 824 of the second main body portion 820 and the opposing surface of the structure 34 is reduced. Moreover, the door mirror device 1 according to the third embodiment can suppress unnecessary mirror angle adjustment and can accurately and quickly adjust the angle of the mirror surface.

[0237] In the door mirror device 1 according to the third embodiment, the spacer 4 is interposed between the base 2 and the mirror housing 30 of the mirror assembly 3, so that the mirror assembly 3 can be smoothly rotated relative to the base 2. As a result, in the door mirror device 1 according to the third embodiment, the first mirror angle adjustment unit 81 and the second mirror angle adjustment unit 82, and the storage unit 6 with the electric storage function can be made smaller, and accordingly the projected area of ​​the front surface (front face) of the structure 34 of the mirror assembly 3 can be made smaller.

[0238] In the door mirror device 1 according to the third embodiment, the edge of the insertion hole 36 of the structure 34 and the edge of the insertion hole 40 of the spacer 4 are provided with mating surfaces 38, 44 that mate with each other, respectively, so that the mirror assembly 3 can be smoothly rotated relative to the base 2. As a result, in the door mirror device 1 according to the third embodiment, similarly to the above, the first mirror angle adjustment unit 81 and the second mirror angle adjustment unit 82 and the storage unit 6 with the electric storage function can be made smaller, and accordingly the projected area of ​​the front surface (front face) of the structure 34 of the mirror assembly 3 can be made smaller.

[0239] In the door mirror device 1 according to the third embodiment, the mating surface 38 of the structure 34 and the mating surface 44 of the spacer 4 are spherical surfaces of revolution with the first axis V1 as the center line, and therefore the mirror assembly 3 can be smoothly rotated relative to the base 2. As a result, in the door mirror device 1 according to the third embodiment, the first mirror angle adjustment unit 81 and the second mirror angle adjustment unit 82, and the storage unit 6 with the electric storage function can be made smaller in size, as in the above-mentioned embodiment, and the projected area of ​​the front surface (front face) of the structure 34 of the mirror assembly 3 can be made smaller accordingly.

[0240] In the door mirror device 1 according to the third embodiment, the mating surface 38 of the structure 34 and the mating surface 44 of the spacer 4 are provided with engagement portions 39 and 45 in the rotation direction with the first axis V1 as the center line. As a result, in the door mirror device 1 according to the third embodiment, when the structure 34 rotates around the storage axis V0 and the second axis V2, the engagement portions 39 and 45 engage with each other, and the spacer 4 rotates together with the structure 34 with respect to the base 2, and when the structure 34 rotates around the first axis V1, the engagement portions 39 and 45 slide against each other, and the spacer 4 does not rotate together with the structure 34 and is in a stopped state together with the base 2. As a result, in the door mirror device 1 according to the third embodiment, the spacer 4 can cover and hide the insertion hole 36 of the spherical convex portion of the structure 34, and the insertion hole 36 of the structure 34 is not visible, resulting in a good appearance. Moreover, even if the insertion hole 36 of the structure 34 is large, the size of the spacer 4 is increased in accordance with the size of the insertion hole 36 of the structure 34, so that the insertion hole 36 of the structure 34 is not visible, resulting in a good appearance.

[0241] As shown in Fig. 48, the door mirror device 1 according to the third embodiment has a shaping surface S3 including a boundary between the shaping surface of the structure 34 and the mating surface 38 of the structure 34, and a surface S4 including a contour of an edge portion facing the shaping surface S3 among the mating surface 44 of the spacer 4, which is formed by extending a curved straight line L on a plane S5 including the storage axis V0 and the second axis V2 in a direction perpendicular to the plane S5. As a result, the door mirror device 1 according to the third embodiment can rotate the spacer 4 together with the structure 34 relative to the base 2 when the structure 34 rotates around the storage axis V0 and around the second axis V2 without providing the engagement parts 39, 45 on the mating surface 38 of the structure 34 and the mating surface 44 of the spacer 4. As a result, the door mirror device 1 according to the third embodiment does not need to provide the engagement parts 39, 45, which simplifies the structure and manufacturing and reduces the manufacturing cost.

[0242] As shown in Figure 17, in the door mirror device 1 of this embodiment 3, the spacer 4 has a flange portion of an upper portion 41 that is arranged between the opposing surface of the spacer support portion 25 of the mounting portion 22 of the base 2 and the mating surface 38 of the structure 34, and this flange portion of the upper portion 41 has a size that covers the recessed opening of the spacer support portion 25 even when the spacer 4 and the structure 34 rotate together around the storage axis V0 and the second axis V2. As a result, in the door mirror device 1 of this embodiment 3, even if the storage axis V0 and the second axis V2 are misaligned as in this embodiment 3 and the gap (rotational gap) between the inner wall surface of the circular concave opening of the spacer support part 25 (see the large circle centered on the second axis V2 shown by the dashed line in Figure 20) and the outer wall surface of the cylindrical lower part 42 of the spacer 4 that fits into the circular concave opening of the spacer support part 25 is not constant, this gap (rotational gap) can be covered and hidden by the flange portion of the upper part 41 of the spacer 4, resulting in a good appearance.

[0243] In the door mirror device 1 according to the third embodiment, the first body portion 810 of the first mirror surface angle adjusting unit 81 and the second body portion 820 of the second mirror surface angle adjusting unit 82 are attached to the fixed side portion 70 of the holding unit 7, so that it is possible to reduce the mass (weight) of the movable side portion 71 of the holding unit 7. As a result, the door mirror device 1 according to the third embodiment can suppress the influence of vehicle vibration on the mirror surface of the structure 34 to which the movable side portion 71 is attached.

[0244] In the door mirror device 1 according to the third embodiment, the distance between one end 813 of the first rod portion 811 of the first mirror surface angle adjustment unit 81 and the holding center CH of the holding unit 7, and the distance between one end 823 of the second rod portion 821 of the second mirror surface angle adjustment unit 82 and the holding center CH of the holding unit 7 are farther apart than the distance between the storage axis V0 and the holding center CH, which are close to each other. As a result, the door mirror device 1 according to the third embodiment can suppress the influence of vehicle vibration on the mirror surface of the structure 34 to which the one end 813 of the first rod portion 811 and the one end 823 of the second rod portion 821 are attached via the movable side portion 71. As a result, the door mirror device 1 according to the third embodiment can suppress the shaking of the mirror surface with less force, and therefore the one end 813 of the first rod portion 811 and the one end 823 of the second rod portion 821 can be attached to the movable side portion 71 by the clips 812 and 822 with a simple structure.

[0245] In the door mirror device 1 according to the third embodiment, the holding unit 7 has a fixed side part 70 attached to the storage unit 6 and a movable side part 71 attached to the structure 34, and the holding center CH is close to the center of gravity CG of the structure 34 and the movable side part 71. As a result, the door mirror device 1 according to the third embodiment can reduce the amount of blurring of the mirror surface of the structure 34 of the movable side part 71, improving visibility.

[0246] In the door mirror device 1 according to the third embodiment, the distance between one end 813 of the first rod portion 811 of the first mirror surface angle adjustment unit 81 and the holding center CH of the holding unit 7, and the distance between one end 823 of the second rod portion 821 of the second mirror surface angle adjustment unit 82 and the holding center CH of the holding unit 7 are farther apart than the distance between the holding center CH and the center of gravity CG, which are close to each other. As a result, the door mirror device 1 according to the third embodiment can suppress the influence of vehicle vibration on the mirror surface of the structure 34 to which the one end 813 of the first rod portion 811 and the one end 823 of the second rod portion 821 are attached via the movable side portion 71. As a result, the door mirror device 1 according to the third embodiment can suppress the shaking of the mirror surface with little force, and therefore the one end 813 of the first rod portion 811 and the one end 823 of the second rod portion 821 can be attached to the movable side portion 71 by the clips 812 and 822 with a simple structure.

[0247] In the door mirror device 1 according to the third embodiment, the camera 5 is attached to the fixed part 70 of the holding unit 7, so that it is possible to reduce the mass (weight) of the movable part 71 of the holding unit 7. As a result, the door mirror device 1 according to the third embodiment can suppress the influence of vehicle vibrations on the mirror surface of the structure 34 to which the movable part 71 is attached.

[0248] Moreover, in the door mirror device 1 according to the third embodiment, the camera 5 is attached to the fixed part 70, so the position of the camera 5 is fixed regardless of the rotation of the movable part 71, as shown in Figures 22, 23 and 24. As a result, the door mirror device 1 according to the third embodiment does not require image processing for correcting the position of the image information obtained by the camera 5 when displaying an image on the around view monitor, so an image with an accurate position can be obtained, and an inexpensive image processing device can be obtained.

[0249] (Description of the configuration, operation, and effect of the fourth embodiment) 49 is a cross-sectional view showing a vehicle mirror device according to a fourth embodiment of the present invention (a cross-sectional view showing a state when the structure of the mirror assembly is located at a neutral position; a cross-sectional view corresponding to FIG. 22). The configuration of the fourth embodiment, like the configuration of the third embodiment, shows a more specific configuration than those of the first and second embodiments.

[0250] Hereinafter, a description will be given of the configuration, operation, and effects of the vehicle mirror device according to the embodiment 4. In Fig. 49, the same reference numerals as those in Figs. 6 to 48 indicate the same parts.

[0251] The door mirror device 1 according to the third embodiment rotates the structure 34 about the second axis V2 to adjust the horizontal angle of the mirror surface. In contrast, the door mirror device according to the fourth embodiment rotates the structure 34 about the storage axis V0 to adjust the horizontal angle of the mirror surface.

[0252] That is, in the door mirror device according to the fourth embodiment, the storage axis V0 serves both a storage function for returning the mirror assembly 3 to its stored state and a mirror surface adjustment function for adjusting the horizontal angle of the mirror surface.

[0253] The door mirror device according to the fourth embodiment does not require the second mirror surface angle adjustment unit 82, and therefore the structure and manufacturing are correspondingly simpler, the manufacturing costs can be reduced, and the weight can be reduced.

[0254] In the door mirror device according to the fourth embodiment, it is not necessary to rotate the movable side part 71 around the storage axis V0 in the holding unit 7 relative to the fixed side part 70. Therefore, in the door mirror device according to the fourth embodiment, as shown in Fig. 49, between the first stopper 901 of the fixed side part 70 of the first rotation range regulating part 91 and the first stopper 901 of the movable side part 71, between the fourth stopper 904 of the fixed side part 70 of the second rotation range regulating part 92 and the fourth stopper 904 of the movable side part 71, and between the sixth stopper 906 of the fixed side part 70 of the second rotation range regulating part 92 and the sixth stopper 906 of the movable side part 71.

[0255] As a result, the door mirror device of embodiment 4 can reliably return the mirror assembly 3 to its folded position, and can also reliably adjust the horizontal angle of the mirror surface, while preventing horizontal wobbling of the mirror surface.

[0256] The door mirror device according to the fourth embodiment does not require the second mirror surface angle adjustment unit 82, and therefore can omit the second fixing portion 742 (the portion surrounded by the two-dot chain line in Figs. 30 and 31) of the first fixed side bracket 74 and the fifth mounting portion 765 (the portion surrounded by the two-dot chain line in Figs. 35, 36, and 37) of the first movable side bracket 76. This allows the door mirror device according to the fourth embodiment to be lighter in weight.

[0257] The door mirror device according to the fourth embodiment can perform a storing function and a horizontal mirror adjustment function by electrically driving the storing unit 6.

[0258] In the door mirror device according to the fourth embodiment, at least one of a backlash-free structure (see JP 2003-343704 A), a rotation stop position detection memory circuit, or a rotation speed variable circuit is added to the storage unit 6. As a result, the door mirror device according to the fourth embodiment can stop the mirror assembly 3 and the mirror surface at a predetermined position without rattling, and can quickly return the mirror assembly 3 to its original position and gently adjust the mirror surface.

[0259] The door mirror device according to the fourth embodiment has the above-mentioned configuration, and therefore can achieve the same functions and effects as the door mirror device 1 according to the third embodiment.
