Filed: 2000-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a visual recognition device for vehicle surroundings which prevents a right-side view image and a left-side view image from overlapping one another at the center of the display. SOLUTION: This visual recognition device for vehicle surroundings 1A has a prism 4 of which the apical angle portion 5 is so chamfered that its near-apical-angle portions 5L and 5R are removed.
