A portion overlapping with the first light shielding plate is formed and moved to the left and right to have a structure including a second light shielding plate which can select and adjust the light shielding area and transmittance.

  Since the present invention is configured as described above, it can be easily attached to and detached from an existing sun visor. By appropriately rotating and sliding the first light shielding plate and the second light shielding plate according to the contact state, direction, and angle of light, the light shielding effect can be obtained. It has an excellent effect that the area can be enlarged and the transmittance can be adjusted and selected instantaneously, and the components can be simplified and manufactured at low cost.

FIG. 1 and FIG. 2 are diagrams showing an embodiment of the present invention, which will be described with reference to FIG.
Reference numeral 1 denotes a semitransparent first light shielding plate formed of a synthetic resin in a rectangular shape, and reference numeral 5 denotes a synthetic resin gripping member formed into a substantially U-shaped body having an elastic force for gripping the existing sun visor 6. .

  A pair of the holding members 5 are provided on the left and right sides, and are integrally formed of synthetic resin or the like so as to be connected by the rotating shaft portion 4. Moreover, the cross section of the rotating shaft part 4 is an ellipse, and the long axis dimension of the ellipse is the inner diameter of the hinge part 3 so that it can be stopped at an arbitrary angle when the first light-shielding plate is rotated by fitting with the hinge part 3. It is set a little longer. The hinge part 3 is formed in a tubular shape, and one of the hinge parts 3 has a C-shaped cross section so that the rotating shaft part can be fitted.

  Reference numeral 2 denotes a second light shielding plate, which is formed of a semi-transparent synthetic resin in a rectangular shape, has a transmittance comparable to that of the first light shielding plate, and is configured to overlap the back surface of the first light shielding plate. It can move left and right along the slide guide 10 of the plate.
