PURPOSE: To increase an anti-glare range according to environments by a method wherein in a sunvisor of a vehicle or the like, a shielding plate to be attached slidable on a rod fixed on the upper part of a room is provided with a cut at its bottom and a colored transparent plate is housed freely movable in its lower portion.

CONSTITUTION: A shielding plate 6 is formed by covering a frame made of plastic or the like with cloth of urethane or the like, and mounted freely slidable on an arm with a slide tube 6b. A cut 6 is formed at the bottom of the shielding plate 6, and a colored transparent plate 7 is housed in the shielding plate 6 so that it can be moved downward. This constitution can prevent glare on a side, where an area to be prevented against light and glare is large, with sliding of the shielding plate 6 and movement of the colored transparent plate 7, improving anti-glare effect.
