[0044] Hereinafter, an example of an embodiment of the electric storage unit, the peripheral vision confirmation device for an electric storage vehicle of the present application will be described in detail based on the drawings. In the scope of the present specification and the technical solution of the other paper, front, rear, upper, lower, left, and right are front, rear, upper, lower, left, and right when the peripheral vision confirmation device for an electric storage vehicle of the present application is mounted on a vehicle. In addition, in the drawings, there are sometimes schematic views, so the main components are illustrated, the illustration of components other than the main components is omitted, and a part of the hatching is omitted.

[0045] (Explanation of the structure of the embodiment)

[0046] Hereinafter, the structure of the electric storage unit, the peripheral vision confirmation device for an electric storage vehicle of the embodiment will be described. In the drawings, reference numeral 1 is the peripheral vision confirmation device for an electric storage vehicle (hereinafter, simply referred to as "vision confirmation device") of the embodiment.

[0047] (Explanation of the peripheral vision confirmation device for an electric storage vehicle 1)

[0048] As shown in Figure 1 , the vision confirmation devices 1 are respectively mounted on the left and right doors (vehicle bodies) D of the vehicle (automobile) V. The vision confirmation devices 1 are substitutes for the outside mirror devices (not shown), such as vehicle rearview mirrors, for example, door mirror devices mounted on the left and right doors D of the vehicle.

[0049] Hereinafter, the vision confirmation device 1 mounted on the left door D of the vehicle V will be described. In addition, the vision confirmation device 1 mounted on the right door D of the vehicle V has substantially the same structure as the vision confirmation device 1 mounted on the left door D of the vehicle V, so the description is omitted.

[0050] As shown in Figures 1 to 5 , the vision confirmation device 1 includes a base 2, a rotation shaft 3, a vision confirmation assembly 4, and display devices (monitors) 5M, 5ML, and 5MR. The base 2, the rotation shaft 3, and the vision confirmation assembly 4 are mounted on the door D, and the display devices 5M, 5ML, and 5MR are mounted in the interior (inside the vehicle) of the vehicle V.

[0051] That is, the left display device 5ML is fitted in the vicinity of the left visual confirmation assembly 4. The right display device 5ML is fitted in the vicinity of the right visual confirmation assembly 4. The center display device 5M is fitted in the vicinity of the driver's seat. Further, at least either one of the left display device 5ML and the right display device 5ML and the center display device 5M can be fitted.

[0052] In Figure 3 , the symbol A is a use position (first position) of the visual confirmation assembly 4. The symbol B is a rear storage position (second position) of the visual confirmation assembly 4. The symbol C is a front storage position of the visual confirmation assembly 4. The symbol E is the rear of the vehicle V. The symbol F is the front of the vehicle V. The symbol O is a rotation center line of the visual confirmation assembly 4, and is also a center line of the shaft portion 30 of the rotation shaft 3, and is also a rotation center line.

[0053] Also, in Figure 3 , the symbol ΘB is an angle at which the visual confirmation assembly 4 is rotated from the use position A to the rear storage position B to be stored in the rear storage position B, that is, a rear rotation storage angle. The rear rotation storage angle ΘB is also an angle at which the visual confirmation assembly 4 is rotated by the motor between the use position A and the rear storage position B, that is, a motor rotation angle. In this example, the rear rotation storage angle ΘB is about 60°.

[0054] Also, in Figure 3 , the symbol ΘC is an angle at which the visual confirmation assembly 4 is rotated from the use position A to the front storage position C to be stored in the front storage position C, that is, a front rotation storage angle. In this example, the front rotation storage angle ΘC is about 80°.

[0055] In a case where the aforementioned visual confirmation unit 5 of the visual confirmation assembly 4 is a camera, the rear rotation storage angle ΘB and the front rotation storage angle ΘC are the same angle in the left visual confirmation device 1 and the right visual confirmation device 1. On the other hand, in a case where the visual confirmation unit 5 is a mirror, the angle of the left visual confirmation device 1 and the angle of the right visual confirmation device 1 are different.

[0056] (Explanation of the base 2)

[0057] The base 2 is composed of a base member and a cover member that covers the base member. As shown in Figure 1 , Figure 3 , and Figure 4 , the base 2 has a first fixed portion 21 of a vertical plate shape and a second fixed portion 22 of a horizontal plate shape. The inside of the base 2 communicates with the inside of the vehicle V via an opening (not shown) of a door panel of the door D.

[0058] The first fixing portion 21 is fixed to the door D by a screw or the like (not shown). As a result, the base 2 is fixed to the door D, i.e., the vehicle body. In the second fixing portion 22, the rotation shaft 3 is fixed by a screw or the like. Further, in the second fixing portion 22, the fixing portion 32 of the rotation shaft 3 is fixed.

[0059] (Explanation of rotation shaft 3)

[0060] As shown in Figure 5 , Figure 6 , the rotation shaft 3 is composed of a hollow cylindrical shaft portion 30, a circular plate portion 31 of a circular plate shape, and a fixing portion 32 of a four-edged plate shape. That is, the circular plate portion 31 is integrally provided at the lower end portion of the shaft portion 30. The fixing portion 32 is integrally provided at the lower surface of the circular plate portion 31.

[0061] The center line (rotation center line) O of the shaft portion 30 passes through the center of the circular plate portion 31. A portion (four-edged plate portion) of the fixing portion 32 protrudes toward the door D with respect to the shaft portion 30 and the circular plate portion 31. The circular plate portion 31 and the fixing portion 32 are provided with a circular or arbitrary shape through-hole which communicates with the hollow portion of the shaft portion 30.

[0062] A fitting portion is provided at the outer peripheral surface of the upper end portion to the intermediate portion of the shaft portion 30. A circular fitting groove is provided at the outer peripheral surface of the upper end portion of the shaft portion 30.

[0063] The fixing portion 32 is fixed to the second fixing portion 22 of the base 2 by a screw or the like. As a result, the rotation shaft 3 is fixed to the base 2.

[0064] An electrically-operated working range limiting protrusion as an electrically-operated working range limiting mechanism is provided at the upper surface of the circular plate portion 31. The electrically-operated working range limiting protrusion limits the range (electrically-operated working range) in which the visual confirmation assembly 4 is rotated by electricity between the use position A and the rear storage position B. That is, the electrically-operated working range limiting protrusion constitutes a stop mechanism which stops the visual confirmation assembly 4 at the use position A and the rear storage position B, respectively.

[0065] Further, a storage working range limiting protrusion as a storage working range limiting mechanism is provided at the upper surface of the circular plate portion 31. The storage working range limiting protrusion limits the storage working range of the visual confirmation assembly 4. The storage working range limiting protrusion is in the shape of a circular arc centered on the center line O of the shaft portion 30.

[0066] (Explanation of visual confirmation assembly 4)

[0067] As shown in Figure 1 , Figure 3 , Figure 4 , the visual confirmation assembly 4 is rotatably mounted to the shaft portion 30 of the rotation shaft 3. The visual confirmation assembly 4 has a housing 4H, a visual confirmation unit 5, and an electrically-operated storage unit 6.

[0068] (Description of casing 4H)

[0069] like Figure 3 as well as Figure 4 As shown, the housing 4H is a hollow, box-shaped structure. In this example, the housing 4H is constructed by dividing it into two parts, which are then watertightly installed through interlocking, bonding, cladding, etc. A circular through hole 40 is provided on the rear surface of the end of the housing 4H opposite to the rotating shaft 3.

[0070] The housing 4H houses the visual confirmation unit 5 and a portion of the motorized retraction unit 6. Specifically, the fixing part 32 of the rotation shaft 3 of the motorized retraction unit 6 is located outside the housing 4H and fixed to the second fixing part 22 of the base 2. Therefore, the housing 4H houses most of the motorized retraction unit 6, except for the fixing part 32 of the rotation shaft 3. Furthermore, sometimes a camera (not shown) separate from the visual confirmation unit 5 is housed within the housing 4H. This camera is used for visual confirmation from below.

[0071] (Explanation of Visual Confirmation Unit 5)

[0072] In this example, the visual verification unit 5 is a camera that captures images of the area surrounding the vehicle V. Figure 2 as well as Figure 4 As shown, the visual confirmation unit 5 has a main body, a lens 51, and a wiring harness 52. The visual confirmation unit 5 is housed in and assembled in the housing 4H.

[0073] The main body is fixed to the housing 4H by screws or the like. The lens 51 faces the through-hole 40 of the housing 4H. The wiring harness 52 is connected to the main body. The wiring harness 52 is disposed inside the vehicle V from inside the housing 4H through the rotating shaft 3 and the base 2. The wiring harness 52 is provided with a connector for electrical connection to the electric storage unit 6.

[0074] In order to capture images of the side and rear views of the vehicle V using the visual confirmation unit 5, which is equal to or greater than the field of view of the existing side mirror device (not shown), the visual confirmation unit 5 needs to be configured to protrude outward from the door D. Therefore, when the visual confirmation assembly 4 is in the use position A, the housing 4H, which houses the visual confirmation unit 5 internally, protrudes outward from the door D. Furthermore, the amount of protrusion of the housing 4H is smaller than that of the existing side mirror device and the vehicle visual confirmation device of Patent Document 1.

[0075] like Figure 2 As shown, the visual verification unit 5 is connected to the image processing device (image processing ECU) 54 via wiring harness 52. The image processing device 54 is connected to the detection device 57 and the display devices 5M, 5ML, and 5MR via signal lines 55 and 56, respectively.

[0076] The visual confirmation unit 5 as a camera captures the information of the rear and side of the vehicle V as an image in the periphery of the vehicle V, and outputs the image of the captured information of the rear and side of the vehicle V to the image processing device 54 via the wire harness 52.

[0077] The detection device 57 is mounted on the vehicle V. The detection device 57 is connected to the image processing device 54 via the signal line 55. The detection device 57 detects the vehicle information, and outputs the detected vehicle information as a detection signal to the image processing device 54 via the signal line 55. As the detection device 57, for example, a steering angle detection unit (steering angle sensor), a gear position detection unit (gear position sensor), a direction indication detection unit (direction indication sensor), a vehicle speed detection unit (vehicle speed sensor), a vehicle position detection unit (vehicle position sensor), an ultrasonic wave detection unit (ultrasonic wave sensor), other detection units, or the like are used singly or in combination.

[0078] The image processing device 54 is mounted on the vehicle V. The image processing device 54 is connected to the visual confirmation unit 5, the detection device 57, the display devices 5M, 5ML, 5MR via the wire harness 52, the signal lines 55, 56, respectively. The image processing device 54 appropriately processes the image of the information of the rear and side of the vehicle V captured by the visual confirmation unit 5, based on the vehicle information from the detection device 57. Further, the image processing device 54 also has a case where the image of the information of the rear and side of the vehicle V captured by the visual confirmation unit 5 is processed by a manual operation of the driver, not based on the vehicle information of the detection device 57. The image processing device 54 outputs the processed image to the display devices 5M, 5ML, 5MR.

[0079] The display devices 5M, 5ML, 5MR are mounted in the field of view of the driver in the interior of the vehicle V. The display device 5M is connected to the image processing device 54 via the signal line 56. The display devices 5M, 5ML, 5MR display the image processed by the image processing device 54. The driver can visually confirm the rear and side of the vehicle V by visually confirming the image displayed on the display devices 5M, 5ML, 5MR. That is, the driver can confirm the rear view of the vehicle V.

[0080] (Explanation of the electric storage unit 6)

[0081] As Figures 5 to 17As shown, the electric storage unit 6 is a component that is partially housed within the housing 4H and is electrically operated to rotate the visual confirmation component 4 between the use position A and the rear storage position B. The electric storage unit 6 includes the aforementioned rotating shaft 3, housings 6U and 6D, motor 7M, reduction mechanism 7, holding component (plate, holding plate) 7H, clutch mechanism 8, rotational force transmission mechanism 9, and limiter 9S of the limiting mechanism.

[0082] The rotating shaft 3, motor 7M, reduction mechanism 7, holding member 7H, clutch mechanism 8, rotational force transmission mechanism 9, and limiter 9S are housed within housings 6U and 6D. The motor 7M, reduction mechanism 7, holding member 7H, and clutch mechanism 8 are arranged in a direction intersecting (orthogonal or approximately orthogonal) the axis of the rotating shaft 3. Furthermore, the axial direction G of the drive shaft (output shaft, rotating shaft) 71M of the motor 7M intersects (orthogonally or approximately orthogonally) the axis of the rotating shaft 3. Here, the axis of the rotating shaft 3 is in the direction of the rotation center line O.

[0083] like Figure 6 as well as Figure 17 As shown in (A), in a top-down view, the clutch mechanism 8 is positioned between the rotational force transmission mechanism 9 and the motor 7M. The orientation H of the rotational force transmission mechanism 9, the clutch mechanism 8, and the motor 7M intersects (or is orthogonal or approximately orthogonal) the axial direction G of the drive shaft 71M of the motor 7M. As a result, the protrusion of the housings 6U and 6D, i.e., the visual confirmation component 4, is... Figure 1 The protrusion (in the left-right direction) is smaller than that of existing side mirror devices and the vehicle vision confirmation device of Patent Document 1. Furthermore, the configuration direction H is the direction connecting the rotation center line O and the axis O1 described later.

[0084] (Instructions for Motor 7M)

[0085] like Figures 6 to 11 As shown, the motor 7M is held in the holding member 7H. The motor 7M is mounted on the housings 6U and 6D via the holding member 7H and is housed within the housings 6U and 6D. A switch circuit board 70M is provided on the motor 7M. Terminals are provided on the switch circuit board 70M. The terminals are disposed in the connector portion of the lower housing 6D. The connector of the wiring harness 52 is detachably fitted into the connector portion of the lower housing 6D and electrically connected to the terminals, thereby powering the motor 7M via the wiring harness 52, the connector, the terminals, and the switch circuit board 70M.

[0086] The motor 7M described above includes a drive shaft 71M, a main body 72M, a cylindrical portion 73M, and an end cap 74M. Specifically, the cylindrical portion 73M is provided on one side of the main body 72M. The drive shaft 71M rotatably protrudes from the cylindrical portion 73M. The end cap 74M is provided on the opposite side of the main body 72M.

[0087] (Explanation of speed reduction mechanism 7)

[0088] As shown in FIG. 1, the speed reduction mechanism 7 is held together with the motor 7M in a holding member 7H. The speed reduction mechanism 7 is installed in the housings 6U, 6D via the holding member 7H together with the motor 7M, and is housed in the housings 6U, 6D. Figures 6 to 12

[0089] The speed reduction mechanism 7 has a first worm gear 71, a second worm gear 72, and a helical gear 73 of an intermediate gear.

[0090] The first worm gear 71 is provided with a first shaft portion 711 as a shaft portion at one end, and a second shaft portion 712 at the other end. The first shaft portion 711 is installed to a drive shaft 71M of the motor 7M. The diameter of the first shaft portion 711 is larger than the diameter of the second shaft portion 712.

[0091] The second worm gear 72 is provided with a first shaft portion 721 at one end, and a second shaft portion 722 at the other end. The diameter of an end portion (front end portion) of the first shaft portion 721 is smaller than the diameter of the other end portion (portion on the second worm gear 72 side) of the first shaft portion 721.

[0092] The helical gear 73 is fixed to the large diameter portion of the first shaft portion 721. As a result, the helical gear 73 rotates together with the second worm gear 72 on the same shaft. The helical gear 73 is engaged with the first worm gear 71.

[0093] (Explanation of clutch mechanism 8)

[0094] As shown in FIG. 1, the clutch mechanism 8 is installed in the housings 6U, 6D, and is housed in the housings 6U, 6D. The clutch mechanism 8 has a clutch rotation shaft 80, a first clutch gear 81, a second clutch gear 82, a clutch 86, a washer 83, a coil-shaped clutch spring 84, and a C-ring 85. Figure 6 Further, the second clutch gear 82 and the clutch 86 of this example are respectively independently configured. The second clutch gear 82 and the clutch 86 are not rotatable relative to each other. However, the second clutch gear 82 and the clutch 86 can be integrally configured.

[0095] The lower end of the clutch rotation shaft 80 is installed to the lower housing 6D. The center line (hereinafter referred to as "axial line") Ol of the clutch rotation shaft 80 is parallel or substantially parallel to the rotation shaft 3, that is, the rotation center line O.

[0096]

[0097] ​​On the clutch rotating shaft 80, from bottom to top and outwards, are fitted a clutch spring 84, a first clutch gear 81, a clutch 86, a second clutch gear 82, a washer 83, and a C-ring 85. Thus, the clutch mechanism 8 is configured as a unit from the lower flange of the clutch rotating shaft 80 to the upper C-ring 85 of the clutch rotating shaft 80. A second worm gear 72 meshes with the second clutch gear 82.

[0098] On the upper surface of the first clutch gear 81, a plurality of notched protrusions, three in this example, are provided at equal or approximately equal intervals in the circumferential direction around the axis O1. On the lower surface of the clutch 86, a plurality of notched recesses, three in this example, are provided at equal or approximately equal intervals in the circumferential direction around the axis O1, corresponding to the three notched protrusions of the first clutch gear 81. Alternatively, notched recesses may be provided on the first clutch gear 81, and notched protrusions may be provided on the clutch 86. Furthermore, when the second clutch gear 82, which serves as the second clutch, is integral with the clutch 86, notched recesses or notched protrusions may be provided on the second clutch gear 82.

[0099] Normally, the notch protrusion of the first clutch gear 81 and the notch recess of the clutch 86 are engaged by the spring force of the clutch spring 84, and the rotational force of the motor 7M will not deviate. The rotational force of the motor 7M is transmitted to the rotational force transmission mechanism 9 via the reduction mechanism 7. In addition, when an external force greater than the rotational force of the motor 7M is applied to the housings 6U and 6D, i.e., the visual confirmation component 4, the notch protrusion of the first clutch gear 81 and the notch recess of the clutch 86 overcome the spring force of the clutch spring 84, and the engagement state is released, becoming an open state. The aforementioned force (i.e., an external force greater than the rotational force of the motor 7M) is not transmitted to the reduction mechanism 7, thereby causing the housings 6U and 6D, i.e., the visual confirmation component 4, to rotate.

[0100] Furthermore, in this example, the entire clutch mechanism 8 is housed within the housings 6U and 6D. However, a portion of the clutch mechanism 8, such as a portion of the clutch rotating shaft 80 or the clutch spring 84, may be disposed outside the housings 6U and 6D.

[0101] (Explanation of the rotational force transmission mechanism 9)

[0102] like Figure 6 As shown, the rotational force transmission mechanism 9 is mounted on the rotating shaft 3 and housed within the housings 6U and 6D. The rotational force transmission mechanism 9 transmits the rotational force of the motor 7M to the housings 6U and 6D via the reduction mechanism 7 and the clutch mechanism 8, causing the housings 6U and 6D, i.e., the visual confirmation component 4, to rotate between the first position (use position A) and the second position (rear storage position B).

[0103] The rotational force transmission mechanism 9 includes a lifting gear 91, a lifting frame 92, and a C-ring 93. The lifting gear 91, the lifting frame 92, and the C-ring 93 are sequentially engaged with the shaft portion 30 of the rotating shaft 3 from the bottom. The second clutch gear 82 of the clutch mechanism 8 is engaged with the lifting gear 91.

[0104] (Instructions for Limiter 9S)

[0105] like Figure 6 As shown, the limiter 9S engages with the shaft portion 30 of the rotating shaft 3, and is located between the coil-shaped spring 90 and the lower housing 6D, and is stored within the housings 6U and 6D. The limiter 9S stops the housings 6U and 6D, i.e., the visual confirmation component 4, at the first use position A and the rear storage position B of the second position, respectively.

[0106] (Instructions for maintaining component 7H)

[0107] like Figures 6 to 14 As shown, the retaining member 7H holds the motor 7M and the reduction mechanism 7, and holds them within the housings 6U and 6D. Consequently, the retaining member 7H, along with the motor 7M and the reduction mechanism 7, is mounted within the housings 6U and 6D, and is housed within them. The retaining member 7H is composed of an elastic component, such as a POM (polypropylene oxide) component. The rigidity of the retaining member 7H is lower than that of the housings 6U and 6D. The retaining member 7H enables the motor 7M and the reduction mechanism 7 to be mounted with high precision within the housings 6U and 6D.

[0108] The retaining member 7H has a first gear retaining part 71H, a second gear retaining part 72H, a first motor engagement retaining part 73H, a second motor engagement retaining part 74H, a first engaged retaining part 75H, a second engaged retaining part 76H, a pair of gear engagement retaining parts 77H, a first rib 78H serving as multiple motor ribs, and at least one (one in this example) second rib 79H serving as a housing rib. The first rib 78H and the second rib 79H are in the shape of reinforcing ribs.

[0109] In this example, the retaining component 7H is manufactured independently as two components (two parts), such as the first retaining component 7H1 and the second retaining component 7H2, by forming with a metal mold.

[0110] (Description of the first retaining component 7H1)

[0111] The first retaining member 7H1 has a first gear retaining part 71H, a second gear retaining part 72H, a first motor engaging retaining part 73H, a first engaged retaining part 75H, a pair of gear engaging retaining parts 77H, multiple first ribs 78H, and multiple second ribs 79H.

[0112] The first retaining member 7H1 is composed of a single component. That is, the first retaining member 7H1 has a basic shape as a hollow cylindrical shape that houses the first worm gear 71, the drive shaft 71M of the motor 7M, and the cylindrical portion 73M. In addition, the first retaining member 7H1 has a shape in which a pair of flat plate shapes are integrally formed on the cylindrical shape, and the pair of flat plate shapes have space to accommodate the helical gear 73.

[0113] (Description of each part of the first retaining component 7H1)

[0114] like Figures 7 to 10 , Figure 14 As shown, a first gear retaining portion 71H is disposed in the middle portion of the first retaining member 7H1. A circular through-hole is provided in the first gear retaining portion 71H. The first shaft portion 711 of the first worm gear 71 is rotatably held in the circular through-hole of the first gear retaining portion 71H. The inner surface of the first gear retaining portion 71H and the outer surface of the first shaft portion 711 have a minimum required clearance.

[0115] like Figure 7 , Figure 10 , Figure 14 As shown, a second gear retaining portion 72H is disposed at one end of the first retaining member 7H1. The second gear retaining portion 72H is a cylindrical shape with one end closed. A second shaft portion 712 of the first worm gear 71 is rotatably held in the circular recess of the second gear retaining portion 72H. The inner surface of the second gear retaining portion 72H and the outer surface of the second shaft portion 712 have a minimum required clearance.

[0116] like Figure 6 , Figure 7 , Figure 10 , Figure 13 , Figure 14 As shown, the first motor engagement and holding portion 73H is located at the other end of the first holding member 7H1. The first motor engagement and holding portion 73H is adjacent to the first gear holding portion 71H and is located on the opposite side from the second gear holding portion 72H. The first motor engagement and holding portion 73H is a hollow cylindrical shape. The cylindrical portion 73M of the motor 7M is engaged and held within the hollow portion of the first motor engagement and holding portion 73H. That is, the first motor engagement and holding portion 73H engages and holds the cylindrical portion 73M from the outside.

[0117] On the inner surface of the first engagement and holding portion 73H of the motor, a plurality of first ribs 78H are integrally provided along the axial direction G. The top surface of the first rib 78H overlaps with the outer surface of the cylindrical portion 73M. As a result, the first engagement and holding portion 73H of the motor can hold the cylindrical portion 73M without loosening by means of the multiple first ribs 78H, as the top surface of the first rib 78H abuts against the outer surface of the cylindrical portion 73M in an overlapping state.

[0118] The portion 710H between the gear first holding portion 71H and the motor first fitting holding portion 73H is a portion 710H adjacent to the gear first holding portion 71H. In the portion 710H adjacent to the gear first holding portion 71H, an insertion hole 711H is provided halfway from the lower side to the upper side. The insertion hole 711H communicates with the through hole of the gear first holding portion 71H and the hollow portion of the motor first fitting holding portion 73H. The shape of the insertion hole 711H is a cuboid shape. The outer shape of the portion 710H adjacent to the gear first holding portion 71H is a cylindrical shape with the same diameter as the motor first fitting holding portion 73H.

[0119] As shown in Figs. 1 and 2, Figures 7 to 11 , Figure 13 , Figure 14 The first fitted holding portion 75H is provided at the middle portion of the first holding member 7H1. The first fitted holding portion 75H is in an integrated configuration with the gear first holding portion 71H. The first fitted holding portion 75H is in the shape of a square plate with one side equal to the diameter of the motor first fitting holding portion 73H. The first fitted holding portion 75H is fitted and held from the outside to the first fitting holding portions 61U, 61D of the housings 6U, 6D.

[0120] On the outer surface of the first fitted holding portion 75H, a plurality of second ribs 79H are integrally provided in the axial direction G. The top surface of the second ribs 79H has an overlapping dimension with the inner surface of the first fitting holding portions 61U, 61D. As a result, the first fitted holding portion 75H is held without play to the first fitting holding portions 61U, 61D via the plurality of second ribs 79H by the top surface of the second ribs 79H abutting the inner surface of the first fitting holding portions 61U, 61D in an overlapping state.

[0121] Here, the gear first holding portion 71H that holds the first shaft portion 711 of the first worm gear 71 is fitted and held to the housings 6U, 6D via the second ribs 79H. On the other hand, the gear second holding portion 72H that holds the second shaft portion 712 of the first worm gear 71 is directly fitted and held to the housings 6U, 6D without passing through the second ribs 79H. As a result, the fitted and held state of the gear second holding portion 72H to the housings 6U, 6D has a degree of freedom compared to the fitted and held state of the gear first holding portion 71H to the housings 6U, 6D.

[0122] As shown in Figs. 1 and 2, Figures 7 to 11 , Figure 13 , Figure 14As shown, a pair of gear engagement and holding portions 77H are the middle parts of the first holding member 7H1 of the holding member 7H, and are disposed between the first gear holding portion 71H, the first engaged holding portion 75H, and the second gear holding portion 72H. A receiving space is provided between the pair of gear engagement and holding portions 77H. The first worm gear 71 and the helical gear 73 of the reduction mechanism 7 are housed in the receiving space. The lower parts of the pair of gear engagement and holding portions 77H are connected as one piece.

[0123] A pair of gear engagement and holding portions 77H are each provided with a circular through hole 770H. The inner diameter of one through hole 770H is smaller than that of the other through hole 770H. The small-diameter portion and the large-diameter portion of the first shaft portion 721 of the second worm gear 72 are rotatably engaged and held in the small-diameter through hole 770H and the large-diameter through hole 770H, respectively. As a result, the second worm gear 72 held in the housings 6U and 6D is engaged in the circular through holes 770H of the pair of gear engagement and holding portions 77H, which are unlikely to cause positional displacement.

[0124] The inner surface of the small-diameter through hole 770H has a minimum required clearance with the outer surface of the small-diameter portion of the first shaft portion 721. Similarly, the inner surface of the large-diameter through hole 770H has a minimum required clearance with the outer surface of the large-diameter portion of the first shaft portion 721.

[0125] As described above, the first retaining member 7H1 of the retaining member 7H houses the first worm gear 71, the drive shaft 71M of the motor 7M, and the cylindrical portion 73M within the cylindrical gear first retaining portion 71H, gear second retaining portion 72H, motor first engaging retaining portion 73H, and first engaged retaining portion 75H. Furthermore, the first retaining member 7H1 of the retaining member 7H houses the helical gear 73 between a pair of flat gear engaging retaining portions 77H.

[0126] (Description of the second retaining component 7H2)

[0127] The second retaining member 7H2 has a second engaging retaining part 74H, a second engaged retaining part 76H, multiple first ribs 78H, and a second rib 79H. One member serves as both the second engaging retaining part 74H and the second engaged retaining part 76H.

[0128] like Figures 6 to 10 , Figure 13 As shown, the second engaging and retaining portion 74H and the second engaged and retaining portion 76H of the motor are C-shaped with a portion of the annular shape cut off. The end cap portion 74M of the motor 7M is engaged and retained within the circular hollow portion of the second engaging and retaining portion 74H (including the second engaged and retaining portion 76H). That is, the second engaging and retaining portion 74H engages and retains the end cap portion 74M from the outside.

[0129] On the inner surface of the motor second fitting holding portion 74H, a plurality of first ribs 78H are integrally provided in the axial direction G. The top surface of the first rib 78H has an overlapping dimension with the outer surface of the end cap portion 74M. As a result, the motor second fitting holding portion 74H is able to non-loosely hold the end cap portion 74M via the plurality of first ribs 78H by the top surface of the first rib 78H abutting against the outer surface of the end cap portion 74M in an overlapping state.

[0130] The second fitting held portion 76H (including the motor second fitting holding portion 74H) is fitted and held from the outside to the second fitting holding portions 62U, 62D of the housings 6U, 6D. On the outer surface of the circular ring-shaped second fitting held portion 76H, a plurality of second ribs 79H are integrally provided in the circumferential direction. The top surface of the second rib 79H has an overlapping dimension with the inner surface of the second fitting holding portions 62U, 62D. As a result, the second fitting held portion 76H is non-loosely held to the second fitting holding portions 62U, 62D via the plurality of second ribs 79H by the top surface of the second rib 79H abutting against the inner surface of the second fitting holding portions 62U, 62D in an overlapping state.

[0131] (Explanation of the housings 6U, 6D)

[0132] As shown in Figs. 1 and 2, the housings 6U, 6D are rotatably installed to the rotating shaft 3, and are fixed to the housing 4H by screws or the like. Figure 5 Figure 6 Figures 9 to 12 Figure 15 Figure 16 As shown in Figs. 1 and 2, the housings 6U, 6D are rotatably installed to the rotating shaft 3, and are fixed to the housing 4H by screws or the like.

[0133] The housings 6U, 6D are composed of an upper housing (cover) 6U and a lower housing (gear box) 6D. The upper housing 6U and the lower housing 6D are fixed to each other by a plurality of screws 60, which are four in this example. The housings 6U, 6D are composed of a member having a rigidity higher than that of the holding member 7H, such as a synthetic resin material (PA material) to which glass fibers are added, or the like. As a result, the housings 6U, 6D have good dimensional stability compared to a member having a rigidity lower than that of the housings 6U, 6D. That is, the housings 6U, 6D have a small dimensional tolerance in manufacturing compared to a member having a rigidity lower than that of the housings 6U, 6D.

[0134] (Explanation of the upper housing 6U)

[0135] As shown in Figs. 1 and 2, the housings 6U, 6D are rotatably installed to the rotating shaft 3, and are fixed to the housing 4H by screws or the like. Figure 5 Figure 6 Figures 9 to 12 ​​​​​​As shown, the upper outer shell 6U is shaped like a cover that closes the opening on the upper surface of the lower outer shell 6D. A circular through-hole 60U is provided at one end of the upper outer shell 6U. The circumference of this through-hole 60U forms a cylindrical portion that is recessed from the upper outer shell 6U. The upper end of the shaft portion 30 of the rotating shaft 3 is fitted into the cylindrical portion of the upper outer shell 6U from the outside. As a result, the upper outer shell 6U can be rotatably mounted on the shaft portion 30 of the rotating shaft 3. The centerline of the cylindrical portion of the upper outer shell 6U (the center of the through-hole 60U) coincides with the centerline O of the shaft portion 30 of the rotating shaft 3, i.e., the rotation centerline O.

[0136] (Description of the lower outer shell 6D)

[0137] like Figure 5 , Figure 6 , Figures 9 to 12 , Figure 15 , Figure 16 As shown, the lower outer casing 6D is a gearbox, shaped like a box with an open upper surface and a closed lower surface. A mounting portion 60D is integrally formed on the bottom surface (lower surface) of one end of the lower outer casing 6D. The mounting portion 60D is a component with a planar shape (shape viewed from above) or a bottom shape (shape viewed from below) that is circular. A circular through-hole is provided in the center of the mounting portion 60D. The center of the mounting portion 60D and the center of the through-hole are concentric and coincide with the rotation center line O.

[0138] The shaft portion 30 of the rotating shaft 3 is inserted through a hole in the lower outer casing 6D. Furthermore, the bottom surface of the mounting portion 60D of the lower outer casing 6D is mounted on the upper surface of the circular plate portion 31 of the rotating shaft 3 via a washer 65. Thus, the outer casings 6U and 6D are rotatably mounted on the rotating shaft 3. In the middle portion of the lower outer casing 6D, a rotating shaft portion 69 is integrally provided for the clutch rotating shaft 80 to engage from the outside.

[0139] (Explanation of the recesses 61, 62, 63, and 64)

[0140] like Figures 9 to 12 As shown, the outer casings 6U and 6D respectively house a rotating shaft 3, a rotational force transmission mechanism 9, a limiter 9S, a clutch mechanism 8, a motor 7M, a reduction mechanism 7, and a holding component 7H. Specifically, the outer casings 6U and 6D have a first storage recess 61, a second storage recess 62, a third storage recess 63, and a fourth storage recess 64. That is, the first storage recess 61, the second storage recess 62, the third storage recess 63, and the fourth storage recess 64 are respectively provided on the opposite surfaces of the upper outer casing 6U and the lower outer casing 6D.

[0141] The first retractable recess 61 is provided at one end of the outer casings 6U and 6D. The first retractable recess 61 houses the rotating shaft 3, the rotational force transmission mechanism 9, the spring 90, the limiter 9S, and the washer 65.

[0142] The second retractable recess 62 is disposed adjacent to the first retractable recess 61 in the middle part of the outer casings 6U and 6D. The clutch mechanism 8 is housed in the second retractable recess 62.

[0143] The third retractable recess 63 is disposed adjacent to the second retractable recess 62 at the other end of the housings 6U and 6D. The motor 7M, the holding member 7H, and the switch circuit board 70M are housed in the third retractable recess 63.

[0144] The fourth retractable recess 64 is disposed adjacent to the second retractable recess 62 in the middle portion of the outer casings 6U and 6D, and is disposed adjacent to the third retractable recess 63 at the other end of the outer casings 6U and 6D. The deceleration mechanism 7 and the holding member 7H are housed in the two fourth retractable recesses 64.

[0145] (Explanation of bearing section 66)

[0146] like Figure 12 as well as Figure 15 As shown, the second worm gear 72 is rotatably supported on the housings 6U and 6D. That is, a bearing portion 66 is provided on the opposing surfaces of the upper housing 6U and the lower housing 6D.

[0147] Bearing portions 66 are respectively provided on one end, the middle, and the other end of the two fourth retractable recesses 64 from the middle portion of the outer casings 6U and 6D to the other end. The small-diameter and large-diameter portions of the first shaft portion 721 of the second worm gear 72, and the second shaft portion 722 of the second worm gear 72 are rotatably supported by the three bearing portions 66. The bearing portions 66 bear the radial load and thrust load of the second worm gear 72.

[0148] (Explanation of fitting and retaining parts 61U, 61D, 62U, 62D, 63U, 63D)

[0149] like Figures 9 to 11 , Figure 15 As shown, the housings 6U and 6D have fitting and retaining portions that fit and retain the retaining member 7H, namely, first fitting and retaining portions 61U and 61D, second fitting and retaining portions 62U and 62D, and third fitting and retaining portions 63U and 63D.

[0150] The first engaging and retaining portions 61U and 61D are disposed between the third retractable recess 63 and the fourth retractable recess 64 of the outer shells 6U and 6D. That is, the first engaging and retaining portions 61U and 61D are disposed on the opposing surfaces of the upper outer shell 6U and the lower outer shell 6D, and on the surface facing the outer surface of the first engaged and retaining portion 75H of the first retaining member 7H1 (which is integrally constructed with the gear first retaining portion 71H). The first engaging and retaining portions 61U and 61D are engaged and retained by clamping the first engaged and retaining portion 75H from above and below, with the second rib 79H of the outer surface of the first engaged and retaining portion 75H flattened.

[0151] The second engaging and retaining portions 62U and 62D are provided at the ends of the third retractable recesses 63 of the outer shells 6U and 6D (the ends opposite to the fourth retractable recesses 64). That is, the second engaging and retaining portions 62U and 62D are provided on the surfaces opposite to the upper outer shell 6U and the lower outer shell 6D, and on the surfaces opposite to the outer surfaces of the second engaged and retaining portion 76H of the second retaining member 7H2 (which is integrally constructed with the second engaged and retaining portion 74H of the motor). The second engaging and retaining portions 62U and 62D are engaged and retained by clamping the second engaged and retaining portion 76H from above and below, with the second rib 79H of the outer surface of the second engaged and retaining portion 76H flattened.

[0152] The third engagement and holding portions 63U and 63D are provided at the ends of the fourth retractable recesses 64 of the outer shells 6U and 6D (the ends opposite to the third retractable recesses 63). That is, the third engagement and holding portions 63U and 63D are provided on the surfaces opposite to the upper outer shell 6U and the lower outer shell 6D, and on the surfaces opposite to the outer surface of the gear second holding portion 72H of the first holding member 7H1. The third engagement and holding portions 63U and 63D engage and hold the gear second holding portion 72H in a manner that clamps the outer surface of the gear second holding portion 72H from above and below.

[0153] (Explanation of bearing components 64D, 65D, 66D, and 67D)

[0154] like Figures 9 to 11 , Figure 15 , Figure 16 As shown, the lower outer shell 6D of the outer shells 6U and 6D has a first bearing portion 64D, a second bearing portion 65D, a third bearing portion 66D, and a fourth bearing portion 67D as bearing portions.

[0155] The first receiving portion 64D is protrusively provided in the third housing recess 63 side of the first fitting holding portion 61D of the lower case 6D toward the upper surface of the lower case 6D. The first receiving portion 64D is provided opposite to the insertion hole 711H of the holding member 7H. The first receiving portion 64D is in a flat shape of a rectangular parallelepiped. The first receiving portion 64D receives the thrust load of the motor 7M side of the first shaft portion 711 of the first worm wheel 71 by being inserted into the insertion hole 711H of the holding member 7H.

The third receiving portion 66D performs positioning in the axial direction of the end cover portion 74M side of the motor 7M by abutting against the end surface of the end cover portion 74M of the motor 7M.

[0158] The fourth receiving portion 67D is provided in the center of the upper end portion of the first receiving portion 64D of the lower case 6D. The fourth receiving portion 67D is provided opposite to the drive shaft 71M of the motor 7M. The fourth receiving portion 67D is in a U shape with a semicircular bottom. The fourth receiving portion 67D maintains a gap with the drive shaft 71M of the motor 7M.

[0159] (Explanation of assembly of the holding member 7H, the motor 7M, and the reduction mechanism 7)

[0160] Hereinafter, the assembly of the holding member 7H, the motor 7M, and the reduction mechanism 7 will be described with reference to Figure 7 and Figure 8

[0161] First, the first shaft portion 711 of the first worm wheel 71 is integrated with the drive shaft 71M of the motor 7M. The end cover portion 74M of the motor 7M is fitted and held in the motor second fitting holding portion 74H of the second holding member 7H2 (a configuration integrated with the second fitted and held portion 76H).

[0162] ​The bevel gear 73 is housed between a pair of gear fitting holding portions 77H of the first holding member 7H1. The first shaft portion 721 of the second worm wheel 72 is rotatably fitted and held in the through hole 770H of the pair of gear fitting holding portions 77H of the first holding member 7H1. At the same time, the first shaft portion 721 of the second worm wheel 72 is passed through the through hole of the bevel gear 73, and the bevel gear 73 is fixed to the second worm wheel 72 as a unit.

[0163] The first holding member 7H1 of the holding member 7H is assembled with the reduction mechanism 7, the motor 7M, and the second holding member 7H2 of the holding member 7H (refer to Figure 7 the solid arrow in FIG. 7). That is, the second shaft portion 712 of the first worm wheel 71 is rotatably held in the gear second holding portion 72H of the first holding member 7H1. The first worm wheel 71 is housed in the first holding member 7H1.

[0176] (Explanation of the electrically rearward retraction)

[0177] When the vision confirmation assembly 4 is located in the use position A shown in FIG. 1, the drive shaft 71M of the motor 7M is caused to rotate forward (or reverse). Then, the rotational force of the drive shaft 71M is transmitted to the housings 6U, 6D via the reduction mechanism 7, the clutch mechanism 8, and the rotational force transmission mechanism 9. Figure 3 The vision confirmation assembly 4 is caused to rotate electrically from the use position A to the rearward retraction position B. When the vision confirmation assembly 4 is located in the rearward retraction position B shown in FIG. 2, the rotation of the vision confirmation assembly 4 is stopped by at least one of the effects of the stop mechanism or the retraction operation range limiting mechanism.

[0178] Figure 3 The vision confirmation assembly 4 is caused to rotate electrically from the use position A to the rearward retraction position B. When the vision confirmation assembly 4 is located in the rearward retraction position B shown in FIG. 2, the rotation of the vision confirmation assembly 4 is stopped by at least one of the effects of the stop mechanism or the retraction operation range limiting mechanism.

[0179] Also, the motor 7M is stalled, a lock current flows, the torque of the motor 7M is output as a maximum torque, the rotation of the motor 7M is stopped by the effect of the switch circuit substrate 70M, and the vision confirmation assembly 4 is stopped and located in the rearward retraction position B.

[0180] (Explanation of the electrically rearward retraction)

[0181] When the vision confirmation assembly 4 is located in the use position A shown in FIG. 1, the drive shaft 71M of the motor 7M is caused to rotate forward (or reverse). Then, the rotational force of the drive shaft 71M is transmitted to the housings 6U, 6D via the reduction mechanism 7, the clutch mechanism 8, and the rotational force transmission mechanism 9.

[0182] The vision confirmation assembly 4 is caused to rotate electrically from the use position A to the rearward retraction position B. When the vision confirmation assembly 4 is located in the rearward retraction position B shown in FIG. 2, the rotation of the vision confirmation assembly 4 is stopped by at least one of the effects of the stop mechanism or the retraction operation range limiting mechanism. Figure 3 The vision confirmation assembly 4 is caused to rotate electrically from the use position A to the rearward retraction position B. When the vision confirmation assembly 4 is located in the rearward retraction position B shown in FIG. 2, the rotation of the vision confirmation assembly 4 is stopped by at least one of the effects of the stop mechanism or the retraction operation range limiting mechanism.​

[0183] And, the motor 7M is stalled, the flow lock current, the torque of the motor 7M is output as the maximum torque, by the action of the switching circuit substrate 70M, the rotation of the motor 7M is stopped, the visual confirmation assembly 4 is stopped and located in the use position A.

[0184] (Explanation of rotation based on manual)

[0185] The visual confirmation assembly 4 located in the use position A can be rotated to the rear E of the vehicle V by manual. In addition, the visual confirmation assembly 4 located in the rear storage position B is reset by rotating to the use position A by manual.

[0186] And, the visual confirmation assembly 4 located in the use position A can be rotated to the front F of the vehicle V by manual. And, the visual confirmation assembly 4 located in the front storage position C is reset by rotating to the use position A by manual.

[0187] (Explanation of effects of the embodiment)

[0188] The electric storage unit 6, the electric storage type vehicle peripheral visual confirmation device 1 of the embodiment has the structure and the action as described above, and the effects thereof will be described below.

[0189] In the electric storage unit 6, the electric storage type vehicle peripheral visual confirmation device 1 of the embodiment, the motor 7M and the reduction mechanism 7 are held to the outer case 6U, 6D having higher rigidity than the rigidity of the holding member 7H via the holding member 7H of the elastic member. As a result, the electric storage unit 6, the electric storage type vehicle peripheral visual confirmation device 1 of the embodiment can smoothly rotate the rotating body (the electric storage unit 6, the visual confirmation assembly 4) in a stable state.

[0190] Furthermore, in the electric storage unit 6, the electric storage type vehicle peripheral visual confirmation device 1 of the embodiment, the first receiving portion 64D of the lower outer case 6D inserted into the insertion hole 711H of the holding member 7H receives the thrust load of the motor 7M side of the first shaft portion 711 of the first worm wheel 71. As a result, the electric storage unit 6, the electric storage type vehicle peripheral visual confirmation device 1 of the embodiment does not apply a burden (load) to the motor 7M, and can smoothly rotate the rotating body (the electric storage unit 6, the visual confirmation assembly 4) in a stable state.

[0191] Moreover, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment is configured such that the insertion hole 711H is provided in the holding member 7H and the first receiving portion 64D is provided in the lower side housing 6D, and thus does not require a special member. That is, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment does not increase the number of components and the manufacturing cost, and enables the rotation body (the electric storage unit 6, the vision confirmation assembly 4) to rotate smoothly in a stable state.

[0192] In the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the cylindrical portion 73M and the end cover portion 74M of both ends of the motor 7M are respectively held in the motor first holding portion 73H and the motor second holding portion 74H of the holding member 7H via the first rib 78H. As a result, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment can absorb the deviation of the dimensional tolerance of the motor 7M and the holding member 7H by the flattening action at the time of assembly of the first rib 78H, and hold (fix) the motor 7M to the holding member 7H without looseness.

[0193] Moreover, in the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the first held holding portion 75H and the second held holding portion 76H of the holding member 7H are respectively held in the first holding portion 61U, 61D and the second holding portion 62U, 62D of the housings 6U, 6D via the second rib 79H. As a result, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment can absorb the deviation of the dimensional tolerance of the holding member 7H and the housings 6U, 6D by the flattening action at the time of assembly of the second rib 79H, and hold (fix) the holding member 7H to the housings 6U, 6D without looseness.

[0194] Thus, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment can hold (fix) the cylindrical portion 73M and the end cover portion 74M of both ends of the motor 7M to the housings 6U, 6D via the holding member 7H without looseness, and thus can prevent the inclination of the motor 7M.

[0195] In the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the first shaft portion 711 and the second shaft portion 712 of the first worm gear 71 of the reduction mechanism 7 are respectively held rotatably to the gear first holding portion 71H and the gear second holding portion 72H of the holding member 7H with a required minimum gap. As a result, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment ensures the degree of freedom between the second shaft portion 712 of the first worm gear 71 and the gear second holding portion 72H of the holding member 7H.

[0196] Thus, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment can maintain (keep) the distance (axle distance) between the first worm wheel 71 axle and the second worm wheel 72 axle of the reduction mechanism 7. As a result, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment can smoothly rotate the rotating body (the electric storage unit 6, the vision confirmation assembly 4) in a stable state.

[0197] Moreover, in the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the gear second holding portion 72H of the holding member 7H that holds the second axle portion 712 of the first worm wheel 71 so as to be rotatable is not fitted and held to the third fitting holding portion 63U, 63D of the housing 6U, 6D via the second rib 79H. As a result, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment can reliably ensure the degree of freedom between the second axle portion 712 of the first worm wheel 71 and the gear second holding portion 72H of the holding member 7H, and reliably maintain (keep) the distance (axle distance) between the first worm wheel 71 axle and the second worm wheel 72 axle of the reduction mechanism 7.

[0198] In the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the gear first holding portion 71H, the gear second holding portion 72H of the holding member 7H, and the motor first fitting holding portion 73H are configured by one member (the first holding member 7H1) in a hollow cylindrical shape that accommodates the first worm wheel 71, the driving axle 71M of the motor 7M, and the cylindrical portion 73M of the reduction mechanism 7. As a result, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment can be inexpensive to manufacture because the holding member 7H is simple in configuration, and thus the metal mold is simple in configuration.

[0199] Moreover, in the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, because one member (the first holding member 7H1) is in a cylindrical shape, the grease such as lubricant in the first worm wheel 71 can be stored for a long period of time.

[0200] Moreover, in the electric storage unit 6 and the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the motor first fitting holding portion 73H that fits and holds the cylindrical portion 73M of the motor 7M and the gear first holding portion 71H and the gear second holding portion 72H that rotatably hold the first shaft portion 711 and the second shaft portion 712 of the first worm gear 71 are one identical member and are manufactured by one identical metal mold. As a result, in the electric storage unit 6 and the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, compared with a holding member (not shown) that is a plurality of members and is manufactured by a plurality of metal molds, the shaft deviation of the motor 7M and the reduction mechanism 7 held by the holding member 7H can be suppressed and the holding member 7H is less likely to be affected by the cumulative tolerance of the plurality of members.

[0201] Moreover, in the electric storage unit 6 and the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the metal mold that molds one member (the first holding member 7H1) of the cylindrical shape of the holding member 7H is a mold that is basically a simple cylindrical shape that is opened in the axial direction. As a result, in the electric storage unit 6 and the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the configuration is simple and one member (the first holding member 7H1) of the cylindrical shape of the holding member 7H can be molded by a low-cost metal mold.

[0202] In the electric storage unit 6 and the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the shaft portion of the second worm gear 72, that is, the first shaft portion 721 that is rotatably held to the housing 6U, 6D is rotatably fitted and held in the circular through hole 770H of the pair of gear fitting holding portions 77H of the holding member 7H in a state in which positional deviation is less likely to occur. As a result, in the electric storage unit 6 and the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the distance (the shaft-to-shaft distance) between the first worm gear 71 shaft and the second worm gear 72 shaft of the reduction mechanism 7 can be reliably maintained (held).

[0203] In the electric storage unit 6 and the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, as shown in Figure 17 (A), in a plan view from above, the clutch mechanism 8 is disposed between the rotation force transmission mechanism 9 (including the rotation shaft 3 and the stopper 9S) and the motor 7M, and the arrangement direction H of the rotation force transmission mechanism 9, the clutch mechanism 8, and the motor 7M crosses the axial direction G of the drive shaft 71M of the motor 7M. As a result, in the electric storage unit 6 and the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the protruding amount (the size in the left-right direction in Figure 1 ) is smaller than the protruding amount of the electric storage unit and the electric storage type vehicle peripheral vision confirmation device disposed as shown in Figure 17 (B).

[0204] Furthermore,Figure 17 (B) is a configuration in which the clutch mechanism 8 is disposed between the rotation force transmission mechanism 9 (including the rotation shaft 3 and the stopper 9S) and the second worm wheel 72 of the reduction mechanism 7, and the rotation force transmission mechanism 9, the clutch mechanism 8, and the second worm wheel 72 of the reduction mechanism 7 are disposed in a direction H parallel to the axial direction G of the drive shaft 71M of the motor 7M.

[0205] In the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of this embodiment, the motor 7M, the reduction mechanism 7, the clutch mechanism 8, and the rotation force transmission mechanism 9 are disposed in a direction (orthogonal or substantially orthogonal direction) intersecting the axial direction (rotation center line O direction) of the rotation shaft 3. As a result, the electric storage unit 6, the vision confirmation assembly 4 of the electric storage type vehicle peripheral vision confirmation device 1 of this embodiment can reduce the size (up-down direction size) in the axial direction (rotation center line O direction) of the rotation shaft 3.

[0206] In the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of this embodiment, the axial direction G of the drive shaft 71M of the motor 7M is made to intersect the axial direction of the rotation shaft 3, so that the size of the axial direction of the rotation shaft 3 of the electric storage unit 6, the vision confirmation assembly 4 can be further reduced.

[0207] The electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of this embodiment can reduce the protruding amount of the electric storage unit 6, the vision confirmation assembly 4, and further reduce the size (up-down direction size) in the axial direction (rotation center line O direction) of the rotation shaft 3 of the electric storage unit 6, the vision confirmation assembly 4, while being able to maintain the diameter of the rotation shaft 3 at the same diameter as before. As a result, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of this embodiment can support the electric storage unit 6, the vision confirmation assembly 4 in a stable state with respect to the up-down load.

[0208] In the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of this embodiment, the vision confirmation unit 5 is a camera device that captures the periphery of the vehicle V, so that the size of the housing 4H of the vision confirmation assembly 4, which houses the vision confirmation unit 5 as a camera device together with the electric storage unit 6, that is, the size of the axial direction of the rotation shaft 3 of the vision confirmation assembly 4, can be reliably reduced compared to an outside mirror device that uses a mirror.

[0209] The electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment can display the image of the information of the rear and the side of the vehicle V, which is captured by the vision confirmation unit 5 as a camera, on the display device 5M, 5ML, 5MR. As a result, in the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment, the driver can visually confirm the image displayed on the display device 5M, 5ML, 5MR, and thus can visually confirm the rear and the side of the vehicle V. Thus, the electric storage unit 6, the electric storage type vehicle peripheral vision confirmation device 1 of the embodiment can contribute to traffic safety as much as a mirror.
