[0028] Hereinafter, the configuration of the base assembly and the vehicle peripheral vision confirmation device according to the present embodiment will be described. Figures 1 to 3 In the figure, reference numeral 1 denotes a peripheral vision confirmation device for a vehicle according to the present embodiment.

[0029] (Description of Vehicle Peripheral Vision Confirmation Device 1)

[0030] In this embodiment, the vehicle peripheral vision confirmation device 1 is a vehicle outside mirror device and a vehicle door mirror (hereinafter referred to as "door mirror 1"). The door mirror 1 is respectively mounted on the left and right doors 10 of the vehicle (refer to FIG. Figure 6 (double-dotted line in ).

[0031] The following describes the door mirror 1 mounted on the right door 10. In this case, the right side of the door mirror 1 is the vehicle's exterior, while the left side is the vehicle's interior. Furthermore, the door mirror 1 mounted on the left door is roughly bilaterally symmetrical with the door mirror 1 mounted on the right door 10. Therefore, the description of the door mirror mounted on the left door will be omitted.

[0032] like Figures 1 to 3 As shown, the door mirror 1 includes a vision confirmation assembly 2 and a base assembly 3. The base assembly 3 is fixed to a panel (door panel, vehicle body panel, or vehicle body exterior panel) of the vehicle door 10. The vision confirmation assembly 2 is mounted on the base assembly 3 so as to be rotatable about a rotation centerline C.

[0033] (Visual confirmation of component 2 instructions)

[0034] like Figures 1 to 3 As shown, the visual confirmation assembly 2 includes a housing 20 , a visual confirmation unit 21 , an electric storage unit (not shown), and a wiring harness H. In some cases, the visual confirmation assembly 2 includes a side turn signal lamp mounted on the housing 20 as a vehicle lamp.

[0035] The housing 20 has a hollow box shape, and its front side (the rear side of the vehicle) is open.

[0036] In this example, the visual confirmation unit 21 is a reflector, located within the opening of the housing 20. The visual confirmation unit 21 is attached to the housing 20 via a drive mechanism (power unit). The drive mechanism allows the mirror surface (reflective mirror) of the visual confirmation unit 21 to rotate left and right around a vertical axis and up and down around a horizontal axis, enabling adjustment of the mirror surface. The reflector may also be equipped with a heater for defogging, an EC layer for automatic anti-glare, or the like.

[0037] Alternatively, a camera can be used as the visual confirmation unit 21 instead of the reflector in this example. If the visual confirmation unit is a camera, the vertical dimensions of the housing 20 are significantly reduced. Furthermore, information about the vehicle's surroundings captured by the camera is displayed on a display device (not shown) inside the vehicle via an image processing device (not shown).

[0038] The electric storage unit electrically enables the visual confirmation component 2 to be in the use position ( Figures 1 to 3 The rear storage position (not shown) can be rotated (see Figure 1 (The solid arrow in the clockwise direction around the rotation center line C).

[0039] The electric storage unit consists of a housing, a rotating shaft, a motor, a switch mechanism, a speed reduction mechanism, and a clutch mechanism. The housing houses the rotating shaft, the motor, the switch mechanism, the speed reduction mechanism, and the clutch mechanism. The housing is housed within and mounted on the housing 20.

[0040] On the other hand, the rotation shaft is attached to the base assembly 3. Thus, the vision confirmation assembly 2 is rotatably attached to the base assembly 3. The center line of the shaft portion of the rotation shaft is the rotation center line C of the vision confirmation assembly 2.

[0041] The harness H is connected to the electric storage unit and the electric and electronic devices of the drive unit.

Alternatively, the rib 7 may be provided integrally on the entire periphery of the fixing portion 40 without the cutout portion 70 .

[0065] The rib 7 abuts against the edge of the gasket 5, causing the edge of the gasket 5 to contact the vehicle door 10, thereby sealing the gap between the gasket 5 and the vehicle door 10. The rib 7 has a lower rib 71 corresponding to the lower edge 45 of the fixing portion 40 of the base 4. Alternatively, the rib 7 may have at least the lower rib 71.

[0066] (Explanation of Spaces S1, S2, and S3)

[0067] The interior of the base assembly 3, that is, the interior surrounded by the base 4, the gasket 5, and the cover 6, forms a first space S1. Furthermore, the interior surrounded by the retaining portion 46 and the connecting portion 47 of the fixing portion 40 of the base 4, and the connecting portion 53 of the gasket 5 forms a second space S2. Furthermore, the interior surrounded by the base 4, the gasket 5, and the cover 6 and located below the first space S1 forms a third space S3.

[0068] The holding portion 46 of the fixed portion 40 surrounding the first space S1 is inclined downward toward the upper drain 80. Also, the connecting portion 53 of the gasket 5 surrounding the second space S2 is inclined downward from the upper drain 80 to the lower drain 81. The lower edge portion 45 of the base 4, the lower edge portion 51 of the gasket 5, and the lower edge portion 60 of the cover 6 surrounding the third space S3 are lowered downward from the lower drain 81 to the final drain 82.

[0069] (Explanation of drains 80, 81, 82)

[0070] As shown in FIG. 1, the upper drain 80 and the lower drain 81 are provided in the fixed portion 40 of the base 4 at positions above the lower side rib 71. Also, the final drain 82 is provided in the gasket 5 at a position below the lower side rib 71. Figures 2 to 6 The upper drain 80 is provided at the front end portion (inclined front end portion) of the holding portion 46 of the fixed portion 40 that contacts the gasket 5. The upper drain 80 causes the water W in the first space S1 to flow down along the inclined portion of the holding portion 46 of the fixed portion 40 into the second space S2.

[0071] The lower drain 81 is provided at the horizontal portion of the connecting portion 47 of the fixed portion 40 opposite the holding portion 46. The lower drain 81 causes the water W in the second space S2 to flow down along the inclined portion of the connecting portion 53 of the gasket 5 into the third space S3.

[0072] The final drain 82 is provided at the vertical portion of the lip portion 54 of the gasket 5. The final drain 82 causes the water W in the third space S3 to flow down along the vertical direction of the lower edge portion 45 of the base 4, the lower edge portion 51 of the gasket 5, and the lower edge portion 60 of the cover 6 toward the outside of the door 10.

[0073] Thus, the first space S1 → the upper drain 80 → the second space S2 → the lower drain 81 → the third space S3 → the final drain 82 constitute a path (drainage path) for draining the water W in the housing 20 of the visual confirmation assembly 2 toward the outside of the door 10.

[0074] The width T1 between the lower edge portion 45 of the base 4 and the lower edge portion 60 of the cover 6 surrounding the third space S3 is larger than the width (i.e., the protruding dimension of the lower side rib 71) T2 between the lower edge portion 45 of the base 4 and the lower edge portion 51 of the gasket 5 opposite each other via the lower side rib 71. Further, T3 is the width when the sealing structure composed of the lower edge portion 45 of the base 4, the lower edge portion 51 of the gasket 5, the lower side rib 71, and the sandwiching member 55 seals the door 10.

As a result, the base member 3, the vehicle peripheral vision confirmation device 1 of the present embodiment have good drainage efficiency.

[0087] In the base member 3, the vehicle peripheral vision confirmation device 1 of the present embodiment, since the width T1 between the lower edge portion 45 of the base 4 and the lower edge portion 60 of the cover 6 that surround the third space S3 is set to be larger than the width T2 between the lower edge portion 45 of the base 4 and the lower edge portion 51 of the gasket 5 that face each other via the lower side rib 71, the width T3 at the time of sealing of the sealing structure can be reduced, and the width T1 of the third space S3 of the drainage path can be ensured to be large. As a result, the base member 3, the vehicle peripheral vision confirmation device 1 of the present embodiment can achieve a space saving of the width T3 up to the sealing surface (the outer surface of the door 10) of the sealing structure, and can maintain the drainage efficiency.

[0088] In the base member 3, the vehicle peripheral vision confirmation device 1 of the present embodiment, since the lip portion 54 that abuts against the door 10 is provided at the front end of the lower edge portion 51 of the gasket 5, the sealing property of the lower edge portion 51 of the gasket 5 and the door 10 can be ensured by the lip portion 54.

[0089] Further, in the base member 3, the vehicle peripheral vision confirmation device 1 of the present embodiment, since the final drain 82 is provided at the lip portion 54, the sealing property can be ensured, and the drainage efficiency can be maintained.
