DETAILED DESCRIPTION

[0024] Below, with reference to accompanying drawing, the vehicle mirror device 10 of present embodiment is described.The rearview mirror device 10 of present embodiment is arranged at the side door (illustration omitted) on the left side of vehicle.In addition, the arrow FR shown suitably in each figure represents the front, and arrow UP represents the top, and arrow LH represents the left.

[0025] like Figures 1 to 3As shown, the door mirror device 10 includes an arm member 15 , a folding mechanism 24 , an actuator support member 25 , a mirror 28 , a sunshade hood 30 , a lower cover 50 , and an upper cover (light shield) 60 .

[0026] One end of the arm member 15 is supported by the side door. A support portion 16 is provided at the other end of the arm member 15. Furthermore, a folding mechanism 24 is provided on the upper surface of the support portion 16, and an actuator support member 25 is provided above the folding mechanism 24. Furthermore, a mirror 28 is supported on a mirror driving actuator (not shown) provided at the rear of the actuator support member 25. When the mirror driving actuator is actuated, the angle of the mirror 28 relative to the actuator support member 25 changes.

[0027] like Figures 2 to 4 As shown, the shading eaves 30, which is an integrally molded product made of resin, includes a frame portion 31, a flange portion 32, a receiving tube 33, a bottom plate portion 34, and a lower supported portion 35. The front shape of the frame portion 31 constituting the rear end portion of the shading eaves 30 is roughly rectangular. The annular flange portion 32 protrudes forward from the outer peripheral edge portion of the frame portion 31. Moreover, the annular receiving tube 33 protrudes forward from the inner peripheral edge portion of the frame portion 31. The amount of the receiving tube 33 protruding forward is greater than that of the flange portion 32. The outer peripheral edge portion of the bottom plate portion 34 is connected to the inner peripheral edge portion of the front end portion of the receiving tube 33. A through hole 34A is formed in the central portion of the bottom plate portion 34. The central axis (axis) AX (refer to Figure 1 、 Figure 8 ) is substantially parallel to the front-rear direction. Moreover, the lower supported portion 35 extends toward the front from the lower end portion of the frame-shaped portion 31.

[0028] like Figures 2 to 4 As shown, a notch 37 having a U-shaped side surface is formed on the left side of the receiving tube 33. The notch 37 includes a first portion 37A constituting the rear end thereof, a second portion 37B extending forward from the upper end of the first portion 37A, and a third portion 37C extending forward from the lower end of the first portion 37A. Therefore, an elastic deformation portion 38 surrounded by the notch 37 is formed on the left side of the receiving tube 33. That is, the rear end of the elastic deformation portion 38 is adjacent to the first portion 37A, the upper edge of the elastic deformation portion 38 is adjacent to the second portion 37B, and the lower edge of the elastic deformation portion 38 is adjacent to the third portion 37C. The elastic deformation portion 38 is a cantilever beam whose front end serves as a supporting end. That is, the elastic deformation portion 38 can be elastically deformed in the thickness direction (inner circumference and outer circumference) of the left side of the receiving tube 33. As shown in FIG. Figure 6 and Figure 7 As shown, when the elastic deformation portion 38 is in the free state, the design surface 33A, which is the inner peripheral surface of the housing tube 33 , and the inner surface of the elastic deformation portion 38 are flush with each other.

[0029] Further Figure 4 and Figure 8 As shown, a first engaging portion 42 is provided on the outer surface (left side) of the elastically deformable portion 38. The first engaging portion 42 is shaped like a substantially triangular prism that is substantially parallel to the vertical direction. The rear surface of the first engaging portion 42 is formed by an engaging surface 43 that is a flat surface, and the outer surface (left side) of the first engaging portion 42 is formed by a guide surface 44 that is a flat surface that is inclined relative to the engaging surface 43 when viewed from above.

[0030] Further Figure 2 、 Figure 3 、 Figure 7 and Figure 8 As shown, the second engaging portion 47 is provided on the entire front edge portion of the flange portion 32 excluding the lower end portion.

[0031] The light shielding eaves 30 having such a structure is partially fixed to the actuator support member 25, and the rear portion of the actuator support member 25 passes through the through hole 34A toward the rear. Figure 1 As shown, the sight glass 28 is located inside the receiving tube 33.

[0032] The lower cover 50 , which is an integrally molded resin product, is fixed to the light shielding eaves 30 by screws at multiple locations.

[0033] The upper cover 60, which is an integrally molded resin product, is a hollow body with its rear and lower surfaces opened. Figure 5 As shown, a first engaged portion 61 is provided on the inner surface of the left side of the upper cover 60. The first engaged portion 61 includes three engaging protrusions 62 separated from each other in the vertical direction. A guided surface 63 is formed on the right edge of each engaging protrusion 62, which is inclined relative to the left-right and front-back directions when viewed from above. An engaged surface 64 is formed on the front edge of each engaging protrusion 62, which is substantially perpendicular to the front-back direction when viewed from above.

[0034] Further Figure 7 and Figure 8 As shown, a second engaged portion 67 composed of a groove is formed on the rear edge of the upper cover 60 over the entire circumference.

[0035] like Figure 2 and Figure 3 As shown in FIG. 1 , if the upper cover 60 separated from the shading eaves 30 in the forward direction is moved backward, the upper cover 60 is Figure 7As shown, the guided surface 63 of each engaging protrusion 62 of the first engaged portion 61 contacts the guide surface 44 of the first engaging portion 42 provided on the elastic deformation portion 38 of the shading eaves 30 in a free state. If the upper cover 60 is moved further rearward from this state, the elastic deformation portion 38 elastically deforms toward the inner peripheral side (right side) of the shading eaves 30 with the supporting end (front end) as the center, so that each engaging protrusion 62 flips over the guide surface 44 rearward. Moreover, when each engaging protrusion 62 moves to a position further rearward than the guide surface 44, the elastic deformation portion 38 wants to return to the free state. As a result, as shown in FIG. Figure 8 As shown, the engaging surface 43 of the first engaging portion 42 of the elastically deformable portion 38, which has been slightly elastically deformed from its free state, engages with the engaged surface 64 of each engaging protrusion 62. Furthermore, the second engaged portion 67 of the upper cover 60 is entirely engaged with the second engaging portion 47 of the flange portion 32 of the light shielding eaves 30. Therefore, as Figure 1 As shown, the upper cover 60 is detachably mounted on the shading eaves 30 and the lower cover 50 in a manner that covers the folding mechanism 24 and the actuator support member 25. Then, the shading eaves 30 and the upper cover 60 are fixed to each other by screws at multiple locations. Figure 1 The rearview mirror arrangement 10 shown is completed.

[0036] Next, the operation of this embodiment will be described.

[0037] The light shielding canopy 30 of the rearview mirror device 10 includes a housing tube 33 extending along the central axis AX, open on one side (the rearward side) in the direction of the central axis AX, and housing the mirror 28. A first engaging portion 42 is provided on the outer periphery of the housing tube 33. Furthermore, the lower cover 50, supported by the light shielding canopy 30 so as to be positioned on the outer periphery of the housing tube 33, includes a first engaged portion 61 that can engage and disengage with the first engaging portion 42. Providing the first engaging portion 42 on the outer periphery of the housing tube 33 allows the light shielding canopy 30 to be provided with a large first engaging portion 42 for engaging with the first engaged portion 61, even when the diameter of the housing tube 33 is small, as centered on the central axis AX. Consequently, the rearview mirror device 10 can achieve a high engagement force between the first engaging portion 42 and the first engaged portion 61, even when the diameter of the housing tube 33 is small.

[0038] Furthermore, since the first engaged portion 61 includes three engaging protrusions 62 , the engaging force between the first engaging portion 42 and the first engaged portion 61 can be increased compared to a case where the first engaged portion 61 is composed of a single engaging protrusion 62 .

[0039] The housing tube 33 of the sunshade canopy 30 of the rearview mirror device 10 includes a cantilever beam-shaped elastically deformable portion 38 provided with a first engaging portion 42 and capable of elastically deforming toward the inner and outer circumferences of the housing tube 33. Therefore, when the upper cover 60 is assembled to the sunshade canopy 30, the first engaging portion 42 and the first engaged portion 61 are easily engaged.

[0040] Furthermore, the rearview mirror device 10 includes a second engaging portion 47 on the sunshade canopy 30 and a second engaged portion 67 on the lower cover 50. The second engaging portion 47 and the second engaged portion 67 engage with each other at a position further rearward than the first engaging portion 42 and the first engaged portion 61. Therefore, relative movement of the upper cover 60 relative to the sunshade canopy 30 in the direction of the central axis AX, to one side (rearward) and the other side (forward), is restricted by the first engaging portion 42, the second engaging portion 47, the first engaged portion 61, and the second engaged portion 67.

[0041] Moreover, if Figure 8 As shown, when the direction perpendicular to the central axis AX in a plan view is defined as the orthogonal direction PX, the engaging surface 43 of the first engaging portion 42, which engages with the engaging protrusion 62, is tilted rearward at an angle α relative to the orthogonal direction PX. Therefore, if a forward external force is applied to the upper cover 60 in this state, each engaging protrusion 62 is guided rightward by the engaging surface 43. In other words, each engaging protrusion 62, due to the engaging surface 43, causes the first engaged portion 61 to move in a direction that increases the engagement between the engaging surface 43 and the engaged surface 64. Therefore, even if a forward force is accidentally applied to the upper cover 60, there is little risk that the engagement between the first engaging portion 42 and the first engaged portion 61 will be disengaged.

[0042] Moreover, a first portion 37A is provided at the rear end portion of the notch 37. Therefore, a tool 70 (see FIG. 1 ) is inserted into the gap between the left side portion of the frame portion 31 and the receiving tube 33 and the left side portion of the sight glass 28. Figure 8 ), the rear end of the elastically deformable portion 38 is moved toward the inside (right side) of the housing tube 33 using the distal end of the tool 70, thereby releasing the engagement between the first engaging portion 42 and the first engaged portion 61 as desired. That is, after removing the plurality of screws from the shading eaves 30 and the upper cover 60, the upper cover 60 can be easily and intentionally removed from the shading eaves 30 using the tool 70.

[0043] Further Figure 6 and Figure 7As shown, when the elastically deformable portion 38 is in the free state, the design surface 33A, which is the inner circumferential surface of the housing tube 33, is coplanar with the inner surface of the elastically deformable portion 38. Therefore, even if the design surface 33A is exposed through the gap between the frame portion 31 and the left side of the housing tube 33 and the left side of the mirror 28, the elastically deformable portion 38 does not easily impair the design of the rearview mirror device 10.

[0044] As mentioned above, the rearview mirror device 10 according to the embodiment has been described. However, the design of the rearview mirror device 10 can be modified as appropriate without departing from the scope of the present invention.

[0045] The first engaged portion 61 may include only one engaging protrusion 62. Alternatively, the first engaged portion 61 may include two or four or more engaging protrusions 62.

[0046] The shape of each first engaged portion 61 may be different from that in the embodiment.

[0047] The present invention can also be applied to the right rearview mirror device.
