  As shown in FIG. 2, the mirror base 3 for supporting the side mirror 1 with respect to the vehicle front door 31 includes the base body 5 fixed to the outer panel 31a and the base body 5 sandwiched from above and below. An upper base cover 7 and a lower base cover 9 that cover a part of the outer surface of the base body 5 are provided.

The base body 5 is made of aluminum die casting, and protrudes to the right in the vehicle width direction from the mounting plate 17 attached to the outer panel 31a of the front door 31 and the upper end portion of the mounting plate 17 as shown in FIGS. In order to reinforce the support plate 19 and the support plate 19, four vertical ribs 21, 23, 25, 27 that connect the lower surface of the support plate 19 and the outer surface of the mounting plate 17, and four vertical ribs Are provided with a front horizontal rib 33 and a rear horizontal rib 35 that connect the front and rear vertical ribs 21 and 27 and the outer surface of the mounting plate 17 respectively.

  The mounting plate 17 is formed with two positioning pins 29 that extend leftward in the vehicle width direction and obliquely downward, and three substantially cylindrical mounting bosses 37 that also extend diagonally downward on the left side in the vehicle width direction. The mounting plate 17 is positioned with respect to the front door 31 by inserting two positioning pins 29 into two positioning holes (not shown) formed in the outer panel 31 a of the front door 31. At the same time, the three bolts are screwed into the screw holes 37a of the three mounting bosses 37 from the vehicle body side to be fixed to the outer panel 31a of the front door 31.

  As shown in FIG. 4, a concave portion 39 having a substantially circular cross section is formed in the central portion of the support plate 19, and a cylindrical portion 41 extending upward from the peripheral portion of the concave portion 39 is formed. By inserting the rotation shaft of the unit into the concave portion 39 and the cylindrical portion 41, the portion of the side mirror 1 above the mirror base 3 is supported. The cylindrical portion 41 is formed with two protrusions 43 protruding outward in the radial direction.

  The support plate 19 is formed with first, second and third engagement holes 45, 47 and 49 having a rectangular cross section around the cylindrical portion 41 in order from the front side. A first positioning hole 51 having a circular cross section is formed so as to be adjacent to the left side of the joint hole 49. Further, a second positioning hole 53 having an oval cross section is formed so as to face the first positioning hole 51 with the cylindrical portion 41 interposed therebetween.

  Both the front and rear horizontal ribs 33 and 35 are formed in a substantially triangular shape in plan view. Thus, the front horizontal rib 33 is formed with a fourth engagement hole 55 having a rectangular cross section at the front edge, and the front edge on the right side of the fourth engagement hole 55 in the vehicle width direction. A first engagement cutout 57 is formed by cutting out a substantially trapezoidal shape. On the other hand, the rear horizontal rib 35 is formed with a fifth engagement hole 59 having a rectangular cross section at the rear edge, and the rear edge is substantially outside the fifth engagement hole 59 in the vehicle width direction. A second engagement notch 61 cut out in a trapezoidal shape is formed.

  Further, as shown in FIG. 5, the frontmost vertical rib 21 among the four vertical ribs is connected to the outer surface of the mounting plate 17 at substantially the same height as the front horizontal rib 33. A horizontal rib 63 is formed, and a front protrusion 65 extending in the vehicle width direction and protruding rearward is formed below the horizontal rib 63. On the other hand, of the four vertical ribs, the rearmost vertical rib 27 has a level substantially equal to that of the rear horizontal rib 35, and connects the vertical rib 27 and the vertical rib 25 on the one front side. A rib 67 is formed, and a rear ridge 69 extending in the vehicle width direction and projecting forward is formed below the horizontal rib 67.

  The upper base cover 7 is a thin resin molded product formed by using a mold, and as shown in FIGS. 6 and 7, a substantially elliptical shape that supports a portion of the side mirror 1 above the mirror base 3. Of the top wall 71, an inclined wall portion 73 that extends from the peripheral portion on the left side in the vehicle width direction of the top wall portion 71 toward the outer panel 31 a of the front door 31 while being gently inclined downward, and the vehicle of the top wall portion 71. It has an upper peripheral wall portion 75 extending downward from a peripheral portion on the right side in the width direction and a front edge portion and a rear edge portion (a peripheral portion excluding an edge portion on the outer panel 31a side) of the inclined wall portion 73. In addition, the lower end surface 75a of the upper side peripheral wall part 75 comprises the mating surface with the lower side base cover 9 (refer FIG.13 and FIG.14).

A circular insertion hole 77 is formed through the top wall 71 at the center thereof, and two notches 79 are formed at the peripheral edge of the insertion hole 77. The top wall 71 has an insertion hole 7.
A first upper engaging portion 81 and a second upper engaging portion 83 that extend downward are formed around the main positioning pin 7 so as to be adjacent to the left side of the second upper engaging portion 83. 85 and a sub positioning pin 87 extending downward so as to face the main positioning pin 85 with the insertion hole 77 interposed therebetween. Further, a third upper engagement portion 89 extending downward is formed in the vicinity of the front boundary between the top wall portion 71 and the inclined wall portion 73, while the rear side of the top wall portion 71 and the inclined wall portion 73. A fourth upper engaging portion 91 extending downward is formed in the vicinity of the boundary.

  These first to fourth upper engaging portions have different vertical lengths (the first upper engaging portion 81 and the second upper engaging portion 83 are short, the third upper engaging portion 89 and the fourth upper engaging portion are short). Although the engaging portion 91 is long), it basically has the same structure, and has a substantially wedge-shaped engaging claw at its tip.

  The main positioning pin (first positioning member) 85 is a protruding member extending downward for positioning the upper base cover 7 with respect to the base body 5, and is formed of two substantially rectangular plates extending downward. It is formed in a cross-like cross section in which members are crossed at right angles. The sub-positioning pin 87 is also a protruding member that extends downward for positioning the upper base cover 7 with respect to the base body 5 and is formed in a cross-shaped cross section like the main positioning pin 85. Unlike the main positioning pin 85, the cross-shaped cross section is formed so as to increase upward from the central portion in the vertical direction.

  Further, four engaging protrusions 93 projecting inward from the inner peripheral surface of the upper peripheral wall 75 are formed at substantially equal intervals, and a space is formed between the upper peripheral wall 75 and the upper peripheral wall 75. Thus, three substantially L-shaped ribs 95 extending downward from the top wall portion 71 are formed so as to be positioned between the four engaging protrusions 93.

  On the other hand, the lower base cover 9 is a thin resin-molded product formed using a mold, like the upper base cover 7. As shown in FIGS. 8 and 9, a substantially semicircular resin plate is used. It is formed in a shape that is bent so as to be bent downward, and the entire peripheral edge portion excluding the edge portion on the outer panel 31a side constitutes a lower peripheral wall portion 97 that extends upward. In addition, the upper end surface 97a of the lower side peripheral wall part 97 comprises the mating surface with the upper side base cover 7 (refer FIG.13 and FIG.14).

  The lower base cover 9 has a first lower engagement portion 99 that extends upward at the front end portion thereof, and a second lower engagement portion 101 that extends upward toward the center in the front-rear direction and the right side in the vehicle width direction. A third lower engaging portion 103 extending upward is formed at the rear end portion. These first to third lower engaging portions have basically the same structure as the first to fourth upper engaging portions, and have substantially wedge-shaped engaging claws at their tip portions.

  Further, the lower base cover 9 has a positioning cylinder at a position corresponding to the main positioning pin 85 of the upper base cover 7 (between the second lower engaging portion 101 and the third lower engaging portion 103). A (second positioning member) 105 is formed. This positioning cylinder 105 is a cylindrical member extending upward for positioning the lower base cover 9 with respect to the upper base cover 7, and the lower side through the pedestal portion 107 formed of a thin plate member. A base cover 9 is provided. Since this pedestal portion 107 is formed in a U-shaped cross section, it can firmly support the positioning cylinder 105 provided at the tip thereof, and the cross section is constituted by a thin plate member. Therefore, the influence of the contraction is reduced, so that the occurrence of sink marks on the outer surface of the lower base cover 9 can be suppressed.

Further, the lower base cover 9 has a rear side of the first lower engagement portion 99, more specifically, at a position corresponding to the right end of the front protrusion 65 of the base body 5 in the vehicle width direction. While a front rotation restricting portion 109 that abuts against the front ridge 65 is formed, on the front side of the third lower engagement portion 103, more specifically, a vehicle in the rear ridge 69 of the base body 5. A rear-side rotation restricting portion 111 that abuts against the rear-side protrusion 69 is formed at a position corresponding to the right end of the width direction.

  Further, the lower base cover 9 has a protruding wall 113 protruding upward and for suppressing the intrusion of wind into the base cover, in the vicinity of the inner side of the lower peripheral wall 97 and the lower peripheral wall 97. It is formed substantially in parallel. As shown in FIG. 13 (A), the protruding wall 113 is provided with a slight gap between the protruding peripheral wall 113 and the lower peripheral wall 97, and the upper end thereof is the upper end of the lower peripheral wall 97. It is formed so as to protrude upward. As a result, even when a gap is formed on the mating surface formed by the lower end surface 75a of the upper peripheral wall portion 75 and the upper end surface 97a of the lower peripheral wall portion 97, the wind that has entered from the gap first begins with the rib wall 113. Therefore, it is possible to prevent the traveling wind from being caught in the base cover. Then, the protrusion wall 113 fits into a space between the substantially L-shaped rib 95 formed on the upper base cover 7 and the upper peripheral wall portion 75, whereby the upper peripheral wall of the upper base cover 7. The upper base cover 7 and the lower base cover 9 are fitted in the inner periphery of each other at the peripheral edge portions.

  Furthermore, four engagement hooks (engagement portions) 115 that are hooked on the four engagement projections 93 formed on the upper base cover 7 are formed on the ridge wall 113. This engagement hook 115 is formed with an engagement hole 115 a at a portion between two notches 113 a formed in the ridge wall 113. Thus, since the engagement hook 115 is edge-cut from the rigid protrusion wall 113 by the two notches 113a, it can be bent and deformed using the elasticity of the resin.

  The base body 5, the upper base cover 7, and the lower base cover 9 configured as described above are assembled as follows.

  That is, in the upper base cover 7, as shown in FIG. 11, the main positioning pin 85 is inserted into the first positioning hole 51 having a circular cross section, and the sub positioning pin 87 is a second positioning hole 53 having an oval cross section. Is positioned with respect to the base body 5. In addition, the cylindrical portion 41 of the base body 5 is fitted in the insertion hole 77 of the upper base cover 7, and two protrusions 43 that protrude radially outward from the cylindrical portion 41 are formed on the peripheral edge of the insertion hole 77. Two notches 79 are fitted. Further, as shown in FIG. 10A, the engaging claw of the fourth upper engaging portion 91 of the upper base cover 7 is engaged with the fifth engaging hole 59 formed in the front horizontal rib 33 of the base body 5. 10B, the engaging claw of the second upper engaging portion 83 of the upper base cover 7 is engaged with the third engaging hole 49 formed in the support plate 19 of the base body 5. As shown in FIG. 10C, the engaging claw of the first upper engaging portion 81 of the upper base cover 7 is engaged with the first engaging hole 45 formed in the support plate 19 of the base body 5. 10D, the engagement claw of the third upper engagement portion 89 of the upper base cover 7 is formed in the fourth engagement hole formed in the front horizontal rib 33 of the base body 5. 55 is engaged.

In this manner, the engagement claws of the four upper engagement portions of the upper base cover 7 engage with the four engagement holes of the base body 5 (more precisely, the hooks are caught by the peripheral portions of the four engagement holes). Thus, the upper base cover 7 is fixed to the base body 5 in the vertical direction. Since the main positioning pin 85 is inserted into the first positioning hole 51, the upper base cover 7 is also fixed to the base body 5 in the front-rear direction and the vehicle width direction. On the other hand, since the main positioning pin 85 having a cross-shaped cross section is inserted into the first positioning hole 51 having a circular cross section, the upper base cover 7 seems to rotate around the main positioning pin 85 with respect to the base body 5. However, when the upper base cover 7 tries to rotate around the main positioning pin 85, the auxiliary positioning pin 87 comes into contact with the long side portion of the second positioning hole 53 having an oval cross section. The base body 5 is also fixed in the direction of rotation around the vertical axis.

  On the other hand, as shown in FIG. 11, the lower base cover 9 is positioned with respect to the upper base cover 7 by the main positioning pins 85 being fitted into the cylindrical holes 105 a of the positioning cylinder 105. Further, as shown in FIG. 12 (A), the engagement claw of the third lower engagement portion 103 of the lower base cover 9 has a second engagement notch formed in the rear horizontal rib 35 of the base body 5. The engaging claw of the second lower engaging portion 101 of the lower base cover 9 is formed on the support plate 19 of the base body 5 as shown in FIG. The engaging claw of the first lower engaging portion 99 of the lower base cover 9 is formed in the front horizontal rib 33 of the base body 5 as shown in FIG. The first engagement notch 57 is engaged. Although not shown, the front rotation restricting portion 109 abuts on the front ridge 65 and the rear turn restricting portion 111 abuts on the rear ridge 69.

  As described above, the engaging claws of the three lower engaging portions of the lower base cover 9 are engaged with one engaging hole and two engaging cutout portions of the base main body 5, so that the lower base cover 9 is fixed to the base body 5 in the vertical direction unless it is intentionally removed. Further, since the main positioning pin 85 is fitted in the tube hole 105 a of the positioning tube 105, the lower base cover 9 is fixed to the upper base cover 7 in the front-rear direction and the vehicle width direction. Further, the lower base cover with respect to the upper base cover 7 is formed by bringing the front rotation restricting portion 109 into contact with the front protruding portion 65 and bringing the rear rotation restricting portion 111 into contact with the rear protruding portion 69. 9 is restricted, and a positional shift is suppressed.

  Further, as shown in FIG. 13A, a ridge wall 113 formed so as to protrude upward from the lower base cover 9 includes a substantially L-shaped rib 95 formed on the upper base cover 7 and an upper side. By fitting in the space between the peripheral wall 75, the upper base cover 7 and the lower base cover 9 are inlay-fitted at the peripheral edges of each other. In this manner, the upper base cover 7 and the lower base cover 9 are fitted into the base using the rib wall 113 for suppressing the intrusion of the wind into the base cover, thereby simplifying the structure. In addition, the protrusion wall 113 protruding upward from the mating surfaces 75a and 97a of the upper base cover 7 and the lower base cover 9 can effectively suppress the intrusion of wind into the base cover. .

  In addition, as shown in FIG. 13B, the four engaging hooks 115 formed on the protruding wall 113 are hooked on the four engaging protrusions 93 formed on the upper base cover 7. Since these engagement hooks 115 can be bent and deformed by being cut off from the rigid ridge wall 113 as described above, the engagement hooks 115 are easily hooked on the engagement protrusions 93 and are temporarily attached to the engagement protrusions 93. When hooked, the upper base cover 7 is pulled toward the lower base cover 9 by the elastic force of the resin. As described above, in the cover base structure of the present embodiment, the engagement is performed in the very vicinity of the upper peripheral wall portion 75 and the lower peripheral wall portion 97 that constitute the mating surfaces 75a and 97a of the upper base cover 7 and the lower base cover 9. Since the mating hook 115 is hooked on the engaging protrusion 93, it is possible to reliably prevent the mating surfaces 75a and 97a from opening.

  If the engaging hook 115 having the engaging hole 115a is formed on the protruding wall 113, a horizontal sliding mold is required in addition to the mold that opens in the vertical direction. If there is a gap (meat stealing) 117 (see FIG. 14B) with the wall 113, it is difficult to pull the slide mold outward. For this reason, when the slide mold is pulled outside, the upper end surface of the lower peripheral wall portion 97 must be formed as shown in FIG. 14A, and the upper peripheral wall portion 75 and the lower peripheral wall portion are formed. Since 97 does not come into contact with the surface, there is a risk that traveling wind or the like is likely to be caught in the base cover.

For this reason, in the cover base structure of the present embodiment, the slide mold is pulled inward, so that FIG.
4 (B), the lower end surface 75a of the upper peripheral wall portion 75 and the upper end surface 97a of the lower peripheral wall portion 97 are brought into surface contact with each other so that the mating surfaces of the lower base cover 9 and the upper base cover 7 are brought into contact with each other. It is difficult for gaps to occur in 75a and 97a.

-Effect-
According to this embodiment, the lower base cover 9 has a mating surface between the upper base cover 7 and the lower base cover 9 in the vicinity of the inner side of the lower peripheral wall 97 and substantially parallel to the lower peripheral wall 97. Since the ridge wall 113 protruding upward from 75a, 97a is formed, even when a gap is generated in the mating surfaces 75a, 97a of the lower base cover 9 and the upper base cover 7, the gap Since the invading wind first hits the rib wall 113, it is possible to prevent the traveling wind or the like from being caught in the base cover.

  In addition, since the protrusion wall 113 provided in the vicinity of the inner side of the lower peripheral wall 97 is formed with an engagement hook 115 that is hooked on the engagement protrusion 93 of the upper base cover 7, The opening of the mating surfaces 75a and 97a with the lower base cover 9 can be suppressed, and the intrusion of wind into the base cover can be further suppressed.

  Further, by cutting the edge of the rigid ridge wall 113 by the two notches 113a, it is possible to easily form the engaging hook 115 that can be bent and deformed using the elasticity of the resin.

  In addition, since the upper base cover 7 and the lower base cover 9 are fitted into the base by using the protruding wall 113 for suppressing the intrusion of the wind into the base cover, the structure can be simplified. it can.
