In a vehicle door mirror, a mirror housing accommodating electric components is rotatably supported at a base member that is mounted to a side door, and a coupler that is electrically connected to the electric components is attached to the base member. A sheet member that is positioned to and held by the base member and is sandwiched between the side door and the base member is fastened to the side door by being fastened together with the base member, and the coupler is clamped between the base member and the sheet member. Accordingly, the coupler can be attached using a fewer number of components and a fewer number of working steps.
