摘要： To provide a blind slat resistant to bending with keeping good rotation of a slat. The slat (16) is formed with a lift cord passing hole (16a) through which a lift cord passes, and when a length of the lift cord passing hole (16a) in a slat width direction is b, a slat width is a, and a slat crown height is e, 0.59 · e a + 0.19 ≤ b a ≤ -1.41 · e a + 0.70 is satisfied, and the slat (16) is formed with a protrusion (16g), which crosses an extension line (16d) of the lift cord passing hole (16a) and protrudes beyond a general plane (16e) of the slat, the extension line (16d) connecting an edge (16b) of the lift cord passing hole (16a) in the slat width direction and an edge (16c) of the slat (16) in the slat width direction.

摘要： The object is to provide a slat for blinds which resists bending while satisfactorily retaining the rotatability of the slat. A slat (16) is formed with lifting/lowering cord insertion holes (16a) through which lifting/lowering cords are inserted, and b/a satisfies A where b is the slat-widthwise length of the lifting/lowering cord insertion hole (16a), a is the slat width, and e is the slat camber, and a projection (16g) is formed which projects beyond the general surface (16e) of the slat across an extension (16d) of the lifting/lowering cord insertion hole (16a) connecting the slat-widthwise end edge (16b) of the lifting/lowering cord insertion hole (16a) and the slat-widthwise end edge (16c) of the slat (16).
