The slider is movable relative to the housing and the camera in a sliding direction, which is a direction toward and away from the opening within the housing. The support shaft is provided on the opening side of the slider and has an axis that is parallel to the sliding direction . The spare mirror is supported by the support shaft so as to be rotatable around the axis of the support shaft. Further, the spare mirror can be changed in the sliding direction to a housing position in which at least a part of the spare mirror is housed in the housing and a pull-out position in which the entire mirror is pulled out of the housing through the opening. The direction of the mirror surface can be changed by rotating the spare mirror around the axis of the support shaft at the drawing position.

  With this configuration, when the camera is normal, the aerodynamic performance is improved while the oblique rear of the vehicle can be visually recognized by the image captured by the camera by positioning the spare mirror at the housing position. be able to. In addition, when the camera breaks down, the spare mirror is positioned at the pull-out position and then rotated around the axis of the support shaft, so that the oblique rear of the vehicle can be viewed with the spare mirror. In other words, according to the present invention, it is possible to improve the aerodynamic performance at the normal time when the camera is normal, and it is possible to visually recognize the oblique rear side of the vehicle with the spare mirror when the camera malfunctions.
