2. Description of the Related Art As one of such conventional visual confirmation devices, there is one disclosed in, for example, U.S. Pat. No. 4,824,159. The conventional visual confirmation device is developed as a mirror device for confirming a state of a rear seat of a vehicle, and defines a storage space for storing a mirror on a ceiling side of the vehicle, and a storage space for an opening of the storage space. When the mirror is rotatably supported and the mirror is rotated from the storage space in the opening direction, the angle of the mirror surface can be adjusted according to the user's line of sight.

For this reason, when it is necessary to look at the mirror under the conventional visual confirmation device, the mirror is rotated in the opening direction from the storage space on the ceiling of the automobile, so that the mirror is not in line with the line of sight of the user. If the angle is adjusted to the position, the user can check the state of the back seat of the car, and if it is not necessary to look at the mirror, on the contrary, turn the mirror into the storage space on the ceiling of the car If it moves, the presence of the mirror will not be in the way.

[0004]

Therefore, in the conventional visual confirmation device, the user can angle the mirror to a position in line with his / her line of sight, so that the state of the rear seat of the automobile can be wide-angled. Although it is possible to confirm the mirror over time, each time the mirror is used, the angle of the mirror must be adjusted to a position suitable for one's line of sight. I could not deny it.

When the mirror is installed in a state where it is angled with respect to the user, this time, when the mirror is stored,
Since the mounting angle of the mirror is fixed at an unnatural angle, the appearance deteriorates.
