PURPOSE:To easily and surely confirm the rear view and the view of the space beside the front of a vehicle and assure safety driving, by fitting a support frame frame with an inner mirror which is circular and has a large radius of curvature and with an outer mirror which is annular and has a small radius of curvature. CONSTITUTION:An almost flat mirror 3, which is circular and has a large radius of curvature, is attached to the central part of a support frame 2 coupled with a support rod 1, which is attached to the front fender of a vehicle so that the support rod 1 can be fixed or adjusted. An annular mirror 4 having a small radius of curvature is secured on the peripheral part of the support frame 2. The boundary edges of the mirrors 3, 4 are fixed in the annular grooves of a holding frame 5. The rear view is confirmed by the inner mirror 3. The view of the space beside the front of the vehicle is confirmed by the outer mirror 4. The images on the mirrors 3, 4 are prevented by the presence of the holding frame 5 from being confused with each other. |
