Abstract: A shield for a helmet includes a shield having a sun visor rotatably and axially supported at a position different from a rotation center of the shield. The sun visor rotates within a range from a first position where the sun visor, like a bill of a hat, lies above a front opening part and projects forward to a second position where the sun visor lies outside facing the shield in an overlapping manner, and the sun visor is retained in the first position. The sun visor is operated and moved forward and away from the shield to rotate from the first position to the second position.
