PROBLEM TO BE SOLVED: To provide a three-frame mirror in which a rear visual field is made sufficient by removing a lower part of four-frame mirror, i.e., a conventional one and preventing deposition of snow and water drop because the visual field by rear view mirror is made well during driving a car. SOLUTION: The deposition of snow and water drop is made less by changing the conventional four-frame to the three-frame to solve a defect of the prior art. COPYRIGHT: (C)2004,JPO
