FLUID RESISTANCE-REDUCING STRUCTURE AND FACE OR HEAD WEAR USING SAID STRUCTURE

摘要

The fluid resistance-reducing structure has multiple protruding stripes (2) on the fluid-contacting surface (1) of the object, the stripes being separated from each other by an interval (i) and formed at an angle (alpha) with respect to the direction of fluid flow. The face or head wear uses said fluid resistance-reducing structure on the fluid-contacting surface (1) thereof. A fluid resistance-reducing structure that is effective in reducing fluid resistance while having a simple structure is thereby provided, and a face or head wear that uses said fluid resistance-reducing structure and is effective in reducing fluid resistance is provided.
