<p>In a shield (4) for a helmet according to this invention, an air introducing mechanism portion (23) disposed at a region including a lower end portion of a shield main body portion (21) and its vicinity includes a large number of vent holes (36) extending substantially in a vertical direction so that a traveling wind can flow substantially upward from substantially below substantially along the inner surface of the shield main body portion (21). This invention can provide a shield (4) for a helmet which, despite that raindrops and the like will enter inside the shield main body portion (21) at a low possibility, can introduce the traveling wind inside the shield main body portion (21) well, and in which the shield main body portion (21) can be worked comparatively well and the strength of the shield main body portion (21) is not particularly impaired.</p> |
