A helmet with shield and having a shield supporting structure that reduces wind-noise, the shield being substantially flush with an outer surface of the helmet shell when fully closed. The shield is ascended or descended against slant surface segments when the shield is moved in a forward or a rearward direction as the supporting shaft is moved in a forward or a rearward direction and the shield is turned in an upward or a downward direction so as to cause the shield to be protruded out of or indented into the step segment.
