PURPOSE:To provide a curve mirror which dispenses with exchange of the mirror to prevent the mirror from dewing or getting misted at the surface thereof and increase the durability and heating efficiency of the mirror, by containing a heater in the inside. CONSTITUTION:A heater 14 and a thermoswitch 15 is provided in the inner space constituted by a mirror 4 and a bracket 3. When the temperature of the inner space has become low, the thermoswitch detects to heat the heater through a controller in a control box 16 and increase the temperature of the mirror 4 in order to remove dew or the like on the surface thereof by evaporation. A heat conductive isolation sheet 11 is attached to the rear face of mirror 4 and a heat isolation material 12 is attached to the face of bracket 3 to increase the heat conductive efficiency to the mirror. A photoelectromotive module 13 is attached to the bracket 3 to make use of solar energy as the electric source necessary for heating the heater. |
