By the way, in recent years, with the diversification of the design of the door portion of the vehicle, a door structure in which the outer edge portion of the mirror base extends to the outer side (outer peripheral side) than the window frame portion of the door has been developed.
As described above, in the door in which the mirror base is provided with the extending portion extending outward from the door frame portion, the appearance from the inside of the vehicle is improved, and the mirror base and the door opening portion are closed when the door is closed. In order to eliminate the gap between them, it is necessary to extend the elastic sheet member interposed between the mirror base and the base mounting seat to the back surface of the extension portion of the mirror base. In this case, the edge portion of the elastic sheet member that is superposed on the back surface of the extending portion needs to be pressed from the back surface side in order to prevent curling up. For this reason, it is considered that a separate plate member is superposed on the edge of the elastic sheet member, the elastic sheet member is sandwiched between the plate members, and the edge of the elastic sheet member is fixed to the extending portion.

  However, in the case where the edge portion of the elastic sheet member is fixed with a separate plate member as described above, there is a concern that the number of parts increases and the mounting operation becomes complicated and the manufacturing cost increases. .

  Accordingly, the present invention is intended to provide a door mirror mounting structure that can prevent the elastic sheet member from being rolled up without increasing the number of parts or complicating the mounting operation.

The invention according to claim 1, which solves the above problem, is provided between a door body (for example, a door body 2 in an embodiment described later) and a door window frame (for example, a door sash 3 in an embodiment described later). A base mounting seat (for example, a mirror installation plate 6 in an embodiment described later) is provided on a mirror base (for example, a mirror base 8 in an embodiment described later) that supports a door mirror (for example, a door mirror 7 in an embodiment described later). An extension portion (for example, an extension portion 9 in an embodiment described later) that extends outward along the door surface direction from the outer edge portion of the window frame portion in a state where the mirror base is attached to the base mounting seat. ), And the mirror base is attached to the base mounting seat from the outside of the vehicle body via an elastic sheet member (for example, an elastic sheet member 10 in an embodiment described later). A door mirror mounting structure to be attached, wherein a locking flange (for example, a locking flange 20 in an embodiment to be described later) that protrudes inward of the vehicle body along an outer edge of the extension portion is provided.
