Abstract: Motor bodies are housed between a case and a case-inner, with the whole of the outside-periphery surrounded by an outer peripheral wall. The upper-side-outer-peripheral face of the outer-peripheral wall slopes continuously downwards on progression from an uppermost portion of the outer-peripheral face towards a vehicle right side edge of the outer-peripheral face, and slopes continuously downwards from the uppermost portion towards the vehicle left side edge of the outer-peripheral face. Accordingly, even suppose water is to reach the upper side of the upper-side-outer-peripheral face, the upper-side-outer peripheral face of the outer-peripheral wall causes such water to always flow downwards towards the lower side of the outer-peripheral wall, and hence water can be suppressed or prevented from remaining standing on the upper-side-outer peripheral face of the outer-peripheral wall 46, enabling water to be suppressed or prevented from seeping in to the motor bodies.

Abstract: Suppressing liquid from seeping into an adjusting section through a discharge hole. In a vehicle door mirror device an opening hole in a holder portion of a mirror-surface adjustment-device is in communication with opening outlet of a mirror holder outer through an opening outlet in the mirror holder outer and a gap between the mirror and the mirror holder outer. Accordingly, even suppose water seeps into the mirror-surface adjustment-device through the opening hole in the holder portion, the water would be externally discharged outside the mirror holder outer through the opening hole, the opening outlet, the gap and the opening outlet. Furthermore, even suppose water at high pressure from outside the mirror holder outer is to reach the opening outlet, the water can be suppressed from seeping into the mirror-surface adjustment-device through the opening outlet and the opening hole due to the water pressure being reduced in the gap.

Abstract: An optical apparatus includes an image source, a scanning mirror, an actuator, and a scanning controller. The image source outputs an image by simultaneously projecting a two-dimensional array of image pixels representing a whole portion of the image. The scanning mirror is positioned in an optical path of the image to reflect the image. The actuator is coupled to the scanning mirror to selectively adjust the scanning mirror about at least one axis. The scanning controller is coupled to the actuator to control a position of the scanning mirror about the at least one axis. The scanning controller includes logic to continuously and repetitiously adjust the position of the scanning mirror to cause the image to be scanned over an eyebox area that is larger than the whole portion of the image.
