  Further, in the connection surface 3e where the surface protrusion 3f1 is formed, an inclined surface 3e1 is formed from the base end portion of the surface protrusion 3f1 toward the inner peripheral surface 3a.

  Returning to FIG. 1, the display unit 4 is arranged along the back surface of the mirror unit 2 to which the mirror frame unit 3 is mounted, and is configured as a display having a screen unit 4 a that displays a display image and a frame 4 b that surrounds the screen unit 4 a. Is done. The driver can visually recognize the display from the surface 2a side of the mirror unit 2 (through the mirror unit 2) by the light emitted from the display. Further, since the shape (size) of the screen of the display is formed to be the same or substantially the same as the mirror surface of the mirror unit 2, the driver visually recognizes the display so as to see the mirror unit 2 through the mirror unit 2 (half mirror). It becomes possible to do. In the drawing, the internal structure of the display unit 4 is omitted.

  The housing body 5 is formed in a container shape having an opening 5 a serving as an entrance for receiving the mirror 2 and the display 4 on which the mirror frame 3 is mounted, and the display 4 and the like are mounted on the housing 5. .

  The mirror cover 6 attached to the opening 5 a of the housing body 5 is formed in a rectangular frame shape and has a window frame-shaped opening 6 a for visually recognizing the mirror portion 2. The peripheral portion of the opening 6a is inclined so as to be recessed toward the opening 6a. The mirror cover 6 is mounted in the opening 5 a of the housing main body 5 to constitute a housing together with the housing main body 5. As shown in FIG. 4A, when the mirror part 2 accommodated in the housing is viewed from the surface 2a side, the mirror cover 6 becomes an outer frame that covers the edge 2d (not shown) of the mirror part 2.

  After the mirror part 2, the mirror frame part 3 and the display part 4 having the above configuration are accommodated in the housing body part 5, the mirror cover 6 is attached to the housing body part 5 so as to sandwich the accommodated members. The room mirror 1 is assembled. As shown in FIGS. 4B and C (the internal structure of the display unit 4 and the housing body 5 are omitted), the mirror frame unit 3 is disposed between the mirror unit 2 and the mirror cover 6 in the interior of the vehicle rearview mirror 1. It is interposed (positioned so as to be sandwiched) between the mirror unit 2 and the display unit 4.

  Next, an example of the process of assembling the vehicle room mirror 1 will be described. First, the mirror part 2 and the mirror frame part 3 are prepared. As shown in FIG. 5A, the opening 3b of the mirror frame 3 is expanded outward by an external force so that the mirror 2 is accommodated in the opening 3b of the elastically deformable mirror frame 3 prepared. Then, a corresponding one side (for example, long side) of the outer periphery of the mirror unit 2 is inserted into a groove 3c (see FIG. 3A) formed on one side (for example, long side) of the inner periphery of the mirror frame 3 with the opening 3b widened. To do. Then, the remaining three sides of the mirror part 2 are also inserted into the groove part 3c, and the external force that widens the opening part 3b is released. Then, as shown in FIG. 5B, the mirror frame portion 3 is mirrored in the state in which the edge 2d (see FIG. 5A) of the mirror portion 2 is fitted into the groove 3c (see FIG. 3A) by the restoring force of the widened opening 3b. 2 is attached.

  After the mirror frame 3 is mounted on the mirror 2, the members are accommodated in the housing main body 5 in the order shown in FIG. 1. First, the display unit 4 is accommodated from the opening 5 a of the housing body 5, and the display unit 4 is mounted on the housing body 5 so that the back surface of the display unit 4 faces the bottom side of the housing body 4.

  After the display unit 4 is mounted, as shown in FIG. 6A (a cross-sectional view in which the internal structure of the display unit 4 and the housing body 5 are omitted), the display unit 4 and the back surface 2b of the mirror unit 2 face each other. The mirror part 2 to which the mirror frame part 3 is mounted is positioned above 4. The mirror part 2 (and the mirror frame part 3) is lowered from that position, and the mirror part 2 is accommodated in the housing main body part 5 so as to overlap the display part 4. In this state, the rear surface protruding portion 3f2 (see FIG. 3B) of the mirror frame portion 3 contacts the surface of the frame 4b (see FIG. 1) of the display portion 4 in a frame shape.

  After the mirror part 2 is accommodated, the mirror cover 6 is positioned above the mirror part 2 as shown in FIG. 6B (a cross-sectional view in which the internal structure of the display part 4 and the housing body part 5 are omitted). The mirror cover 6 is lowered from that position, and the mirror cover 6 is attached to the housing body 5.

  When the mirror cover 6 is lowered, the frame-shaped surface protrusion 3f1 (see FIG. 3B) contacts the frame back so as to surround the opening 6a on the back surface of the mirror cover 6. When the mirror cover 6 is further lowered from this state, the mirror frame part 3 is crushed by the mirror cover 6 and the display part 4. Therefore, as shown in FIG. 4C, the tip of the front surface protruding portion 3f1 is deformed along the shape of the back surface of the mirror cover 6, and the gap between the mirror cover 6 and the mirror frame portion 3 is sealed. Similarly, the front end portion of the rear surface protruding portion 3f2 is also deformed along the surface of the display portion 4, and the gap between the mirror frame portion 3 and the display portion 4 is also sealed.

  As described above, since the mirror frame portion 3 is interposed between the mirror portion 2 and the display portion 4 and seals between the mirror portion 2 and the display portion 4, the sealing between the mirror frame portion 3 and the display portion 4 is performed. Therefore, it is possible to prevent dust from entering between the mirror unit 2 and the display unit 4 from the outside. Further, since the mirror frame portion 3 is also interposed between the mirror portion 2 and the mirror cover 6, it is possible to prevent the mirror portion 2 from coming into direct contact with the mirror cover 6 and reduce the load on the mirror portion 2.

  Since the mirror frame portion 3 is elastically deformable, even if the components constituting the vehicle rearview mirror 1 vary, the mirror interposed between the mirror portion 2 and the display portion 4 or between the mirror portion 2 and the mirror cover 6. The frame part 3 is elastically deformed according to the variation between components. For this reason, sealing can be performed so as to absorb variations among components, and the sealing performance can be improved. 3B, the edge 2b of the mirror 2 is fitted into the groove 3c of the mirror frame 3, and the mirror frame 3 is attached to the mirror 2. As shown in FIG. Therefore, it is possible to prevent dust from entering the back surface 2b from the front surface 2a of the mirror unit 2 through the gap between the mirror unit 2 and the mirror frame unit 3. Further, by using the mirror frame portion 3 as an integrally molded component, it is possible to eliminate the gap in the mirror frame portion 3 itself and to more effectively suppress the intrusion of dust.

  Further, as shown in FIGS. 3A and 4C, the front surface protruding portion 3f1 of the mirror frame portion 3 protrudes toward the mirror cover 6, and contacts the back surface of the mirror cover 6 in a rectangular frame shape. At this time, the tip of the elastically deformable surface protrusion 3f1 has a convex curved surface, so that the tip follows the rear surface of the mirror cover 6 and deforms, and the space between the mirror cover 6 and the mirror frame 3 is sealed. Will increase. The same is true between the rear surface protruding portion 3f2 and the display portion 4.

  Further, the peripheral portion of the opening 6a of the mirror cover 6 is inclined so as to be recessed toward the opening 6a. Correspondingly, an inclined surface 3e1 is formed from the base end portion of the surface protruding portion 3f1 toward the inner peripheral surface 3a. Therefore, when the mirror cover 6 is mounted on the housing main body 5, the inclined surface 3e1 contacts the opening 6a or its peripheral portion, thereby preventing the seal between the mirror frame portion 3 and the mirror cover 6 from becoming incomplete.

  Further, as shown in FIGS. 5A and 5B, the mirror frame portion 3 is attached to the mirror portion 2 by utilizing elastic deformation and its restoring force, so that it can be easily attached and is not easily detached. Further, since the front surface 2a and the back surface 2b (excluding the edge portion 2d) of the mirror unit 2 are exposed from the opening 3b in a state where the mirror frame unit 3 is mounted on the mirror unit 2, when the driver visually recognizes the room mirror 1 Further, the mirror frame part 3 does not block the mirror part 2 and the display part 4.

  Although the embodiment of the present invention has been described above, the present invention is not limited to the specific description, and the illustrated configuration, processing, and the like may be appropriately combined and implemented within a technically consistent range. It is possible, and certain elements and processes can be replaced with known forms.
