PROBLEM TO BE SOLVED: To provide a screen capable of eliminating a sense of blockage by making it possible to freely open and close a vane in spite of the fact that the screen using a frosted glass or the like is mostly used in a room and that a fence such as block, concrete or the like is mostly used in the open to feel like blocking as a common blindfold. SOLUTION: The effect of a bearing by combining a stainless steel-made pipe 1 with a shaft 2 is obtained to enable both aluminum and wooden products to smoothly open and close.
