  Moreover, the side door 10 is provided with a door inner panel (not shown) that constitutes a door inner plate in a vehicle body inner side portion of the door body. Between the door outer panel 12 and a door inner panel (not shown), a door belt line outer reinforcement (hereinafter simply referred to as “outer reinforcement”) 14 is disposed on the door outer panel 12 side. The outer reinforcement 14 is a high-strength and high-rigidity member for reinforcing the upper portion of the door. The outer reinforcement 14 has a long shape and extends in the longitudinal direction of the vehicle body along the door belt line of the door outer panel 12. The outer reinforcement 14 is joined to the inside of the door by welding. Further, the outer reinforcement 14 is provided with a mounting plate portion 14 </ b> A (which is an element grasped as an “attachment target portion” in a broad sense) at a portion facing the through hole 12 </ b> A of the door outer panel 12. The mounting plate portion 14 </ b> A is provided in a stepped shape portion that is lowered by one step inwardly in the door thickness direction with respect to the upper and lower portions of the outer reinforcement 14.

  A lower portion 22A of a stay 22 (base) as a support member constituting the door mirror device 20 is attached to the mounting plate portion 14A on the vehicle body side. The stay 22 is formed in a metal (for example, aluminum alloy) columnar shape, and is inserted into the through hole 12A on the vehicle body side. In addition, the insertion direction to 12 A of through-holes at the time of the assembly | attachment of the stay 22 is shown by the arrow A direction in the figure, and this direction is hereafter abbreviated as an assembly direction. The lower portion 22A of the stay 22 is disposed on the door inner side (vehicle body inner side) with respect to the door outer panel 12, and includes a protruding portion 122A protruding in a convex shape toward the mounting plate portion 14A at the lowermost portion. The bottom surface of the protruding portion 122A of the stay 22 is disposed on the mounting plate portion 14A, and a bolt 24 (a male screw portion) is provided in a screw hole (female screw portion) 22C formed in the lower portion 22A of the stay 22. ) Are screwed together to apply a fastening load to the mounting plate portion 14A. Thereby, the lower part 22 </ b> A of the stay 22 is fixed to the mounting plate part 14 </ b> A of the outer reinforcement 14.

  FIG. 3 shows a rear view of the portion taken along line 3 of FIG. 2 in a state where the outer reinforcement 14 is seen through. As shown in FIG. 3, the lower portion 22A of the stay 22 is fastened to the mounting plate portion 14A (see FIG. 2) at a total of three locations. Note that the through hole 12A of the door outer panel 12 is set to be larger than the lower portion 22A of the stay 22.

  As shown in FIG. 2, the upper portion of the stay 22 is disposed on the door outer side (vehicle body outer side) with respect to the door outer panel 12. A mounting portion (not shown) of a stay cover 30 (base cover) as a second covering member is fixed to the upper portion of the stay 22 by fastening fastening means (bolts or the like). In addition, a hole 30 </ b> A for penetrating the top wall portion 22 </ b> B provided on the upper portion of the stay 22 is formed through the upper portion of the stay cover 30. The stay cover 30 is made of resin having rigidity, is formed in a substantially box shape opened toward the outer reinforcement 14 side, and covers the outer periphery from the upper portion of the stay 22 to the intermediate portion. Further, the lower side of the stay cover 30 is inserted into the through hole 12 </ b> A integrally with the stay 22. Here, a predetermined gap is set between the outer peripheral surface of the stay cover 30 and the through hole 12A, and a gasket 28 is provided as a sealing member for sealing between the stay cover 30 and the through hole 12A. ing.

  The gasket 28 is a substantially container-shaped rubber member having elasticity for preventing wind noise, and is disposed over the entire circumference between the stay cover 30 and the through hole 12A. The bottom portion 28 </ b> C of the gasket 28 is penetrated by the projecting portion 122 </ b> A of the stay 22 and is pressed against the mounting plate portion 14 </ b> A by the lower portion 22 </ b> A of the stay 22. Further, the gasket 28 has a vertical wall in which the outer diameter of the vertical wall portion 28B closely contacting the through hole 12A of the door outer panel 12 is slightly larger than the inner diameter of the through hole 12A and closely contacting the outer peripheral surface of the stay cover 30. The inner diameter of the inner surface of the portion 28 </ b> B is set slightly smaller than the outer dimension of the stay cover 30. That is, the vertical wall portion 28 </ b> B of the gasket 28 is in close contact with the through hole 12 </ b> A and the stay cover 30 while being slightly pressed inward in the thickness direction. Further, the lip portion 28 </ b> A provided at the outer peripheral end of the gasket 28 is elastically pressed against the outer surface of the door outer panel 12.

  As shown in FIG. 4A, the gasket 28 before being arranged has a shape in which the lip portion 28A is bent at an acute angle with respect to the vertical wall portion 28B. 4B, the gasket 28 changes the angle of the lip portion 28A with respect to the vertical wall portion 28B according to the relative position in the assembly direction (arrow A direction) with respect to the door outer panel 12. The variation in the relative position is absorbed. In other words, the shape of the gasket 28 shown in FIG. 4A before being disposed is that the relative position of the mounting plate portion 14A (with which the bottom portion 28C is in contact) with respect to the door outer panel 12 varies in the assembling direction (arrow A direction). The gasket 28 has a height h from the pressure contact side proximal end a to the distal end b of the lip portion 28A (along the standing direction of the vertical wall portion 28B) due to deformation (displacement) of the lip portion 28A. Variation in the assembly direction (arrow A direction) can be absorbed within the range of (length).

  As shown in FIG. 2, a mirror device main body 32 is disposed above the top wall portion 22B of the stay 22, and a support shaft for a storage mechanism of the mirror device main body 32 is provided on the upper surface side of the top wall portion 22B. 34A is attached. A visor cover 36 as a first covering member is attached to the storage mechanism via a metal frame (not shown). In other words, the visor cover 36 is supported by the stay 22 via the frame and the storage mechanism. The visor cover 36 is disposed above the stay cover 30. The parting part 40 between the visor cover 36 and the stay cover 30 is set outside the vehicle body of the through hole 12A, and a gap 40A is set between the bottom surface 36A of the visor cover 36 and the upper surface 30B of the stay cover 30. .

  Thus, in a state where the storage mechanism is operated, the visor cover 36 does not interfere with the stay cover 30, and the frame (not shown), the visor cover 36, and the like rotate with respect to the stay 22 on the fixed side. The mirror 38 (see FIG. 1), which will be described later, moves between a retracted position where the mirror surface faces inward in the vehicle width direction and a deployed position where the mirror surface faces substantially the rear side of the vehicle.

  As shown in FIG. 1, the visor cover 36 is formed in a substantially bowl shape and constitutes the outer shape of the mirror device main body 32, and a mirror 38 is provided inside the vicinity of the opening end thereof. The mirror surface of the mirror 38 is directed toward the opening side of the visor cover 36, and the anti-mirror surface side (the opposite side of the mirror surface) of the mirror 38 is covered with the visor cover 36. Further, a mirror surface adjustment mechanism (not shown) is disposed inside the visor cover 36 on the side opposite to the mirror surface of the mirror 38, and the mirror 38 is supported by the mirror surface adjustment mechanism. The mirror surface adjustment mechanism is attached to a frame (not shown).

(Operation and effect of the embodiment)
Next, the operation and effect of the above embodiment will be described.

  As shown in FIG. 2, the stay 22 is inserted into a through hole 12 </ b> A formed in the door outer panel 12 and attached to the mounting plate portion 14 </ b> A on the vehicle body side, and a stay cover 30 that covers the stay 22 is attached to the stay 22. Since it is fixed and inserted into the through hole 12A integrally with the stay 22, even if the position of the stay cover 30 with respect to the door outer panel 12 varies in the assembly direction (direction of arrow A), the stay cover 30 and the door outer panel 12 Interference is prevented or suppressed.

  As a result, distortion and cracking of both due to interference between the stay cover 30 and the door outer panel 12 are prevented or suppressed. Incidentally, if the door outer panel is made thinner as in recent years, the door outer panel may be distorted due to the interference between the stay cover side and the door outer panel. In the management, occurrence of the cause of the distortion can be prevented or suppressed. The gap management is management for avoiding interference, but there is also an aspect of management of appearance quality (maintaining a constant feeling of gap).

  Here, a supplementary explanation will be made in comparison with the comparison structure.For example, the lower end of the stay cover is arranged on the outer peripheral side of the through hole of the door outer panel, and a gap is formed between the lower end of the stay cover and the outer surface of the door outer panel. In the contrast structure to be formed, it is necessary to manage the gap in the assembly direction (see the direction of arrow A in FIG. 2). For this reason, the gap management is difficult in consideration of component tolerances on the door mirror device side and the side door side. That is, in the contrast structure, when the height dimension of the stay or the stay cover varies or the position of the mounting plate portion of the outer reinforcement for attaching the stay shifts in the assembling direction, the lower end portion of the stay cover and the outer surface of the door outer panel The interval between will change. In particular, since the outer reinforcement is joined to the inside of the door by welding, the position of the mounting plate portion of the outer reinforcement to which the stay is attached is difficult to manage with high accuracy and generally tends to vary. Therefore, in the contrast structure, in order to keep the gap at a predetermined interval, for example, a structure for absorbing a dimensional error on the vehicle body side (for example, a structure in which another part such as a spacer is provided) is required. , Gap management becomes complicated.

  On the other hand, in the door mirror device 20 according to the present embodiment, the gap management in the assembly direction (see the arrow A direction) is the gap management in the direction along the surface direction of the door outer panel 12, that is, the outer shape of the stay cover 30. And the management of the shape of the through hole 12A. For example, the stay cover 30 is moved in the mounting direction (the direction of the arrow A) when the position of the mounting plate portion 14A of the outer reinforcement 14 is shifted in the mounting direction (arrow A direction). Even if it deviates in the direction of arrow A), the influence on the gap management is very small as compared with the contrast structure. This eliminates the need for gap management in the assembly direction (arrow A direction), facilitates gap management, and eliminates the need for a structure for absorbing dimensional errors on the vehicle body, resulting in high costs. It can be suppressed.

  As another contrasting structure, for example, in a contrasting structure in which the stay (22) is covered with a raised portion obtained by raising a part of the door outer panel (12) instead of the stay cover (30), the movable visor cover It is necessary to manage the gap between the fixed part and the raised part on the fixed side. That is, the stay cover needs to be moved or rotated relative to the vehicle body side (the raised portion) electrically or manually when the door mirror is deployed and retracted. It is necessary to set a gap between the raised portions so that they do not interfere with each other when the stay cover is relatively moved (turned or the like). In this contrast structure, the gap management also serves as the gap management of the building. However, the gap management in such a contrast structure is directly affected by the dimensional variation (error) on the door outer panel side (the raised portion).

  On the other hand, in the door mirror device 20 according to the present embodiment, the stay cover 30 that covers the stay 22 is fixed to the stay 22 instead of a part of the door outer panel 12, so that the movable side visor cover 36 and the fixed side cover are fixed. The management of the gap 40 </ b> A between the parting portion 40 and the stay cover 30 is self-contained within the door mirror device 20 without being affected by variations in dimensions on the door outer panel 12 side.

  Further, in this embodiment, the parting part 40 between the visor cover 36 and the stay cover 30 is set outside the vehicle body of the through hole 12A, so that interference between the visor cover 36 and the door outer panel 12 can be easily prevented or suppressed.

  Furthermore, in the door mirror device 20 according to the present embodiment, the space between the stay cover 30 and the through hole 12A (building gap) is sealed by the gasket 28, so that the vehicle is between the stay cover 30 and the through hole 12A. Is prevented or suppressed (simplification of measures against wind noise). Even if the gap dimension between the stay cover 30 and the through hole 12A varies, the gasket 28 absorbs the gap dimension variation to some extent, and the robustness is good.

  Supplementally, if the stay cover 30 has a straight shape in the assembling direction (arrow A direction), the stay cover 30 and the through-hole 12A can be used even if the position of the stay cover 30 varies in the assembling direction (arrow A direction). However, in the case where the stay cover 30 has a shape that is slightly widened from the viewpoint of design or the like, the position of the stay cover 30 is the assembling direction (direction of arrow A). If it fluctuates, the gap dimension between the stay cover 30 and the through hole 12A changes. Even in such a case, the gasket 28 absorbs the variation in the gap size.

  As described above, according to the door mirror device 20 according to the present embodiment, interference with the door outer panel 12 can be prevented or suppressed.

(Supplementary explanation of the embodiment)
In the above-described embodiment, the case where the vehicle outer mirror device is applied to the door mirror device 20 has been described. However, in the vehicle outer mirror device, for example, a mirror such as a fender mirror device is disposed outside the vehicle body. Other vehicle outer mirror devices may be used.

  In the above embodiment, the stay 22 is inserted into the through hole 12A formed in the door outer panel 12 and attached to the mounting plate portion 14A of the outer reinforcement 14, but the stay (support member) is, for example, the vehicle body side. Other stays such as stays (support members) that are inserted into the opening (insertion part) of the recess formed in the door outer panel (vehicle body outer plate) and attached to the bottom (attachment target part) of the recess ( Support member).

  Furthermore, in the above embodiment, the parting part 40 between the visor cover 36 and the stay cover 30 is set outside the vehicle body of the through hole 12A, and such a configuration is preferable. For example, the first covering member and the second covering member The parting section may be set at the height position of the insertion part, or may be set inside the vehicle body of the insertion part.

  Furthermore, in the above embodiment, the space between the stay cover 30 and the through hole 12A is sealed by the gasket 28, but the sealing member for sealing between the second covering member and the insertion portion is an O-ring. Other sealing members such as may be used.

  In the above embodiment, the screw hole 22C is formed in the lower portion 22A of the stay 22, and the bolt 24 penetrates from the inside of the door of the mounting plate portion 14A and is screwed into the screw hole 22C of the stay 22. The lower portion 22A of the stay 22 is fixed to the mounting plate portion 14A. For example, a stud bolt (fastening member having a male screw portion) is erected on the lower portion (22A) of the stay (22) to attach the mounting plate portion ( 14A) and a nut (female screw member) is screwed into the stud bolt inside the door of the mounting plate portion (14A), so that the lower portion (22A) of the stay (22) is attached to the mounting plate portion. (14A) may be fixed.
