The shielding device for a helmet comprises a shield 10 to cover the opened portion of the helmet body 1; a sun visor 20 which is placed on the inside of the shield 10 to shut off sunlight; a visor 30 which is placed between the shield 10 and the sun visor 20 to block the inflow of rainwater; a hinge joining means 40 which pivotably supports both ends of the shield 10 and sun visor 30 so that they can pivot up and down in one body and/or individually; and a rotation interruption means 50 which obstructs the shield 10, sun visor 20 and visor 30 from descending due to self weight as well as makes the shield 10 be pivoted intermittently with respect to the visor 30.
