PROBLEM TO BE SOLVED: To provide a slat lifting/lowering apparatus for a horizontal blind, which can reduce the number of components and the number of man-hours for assembly while enabling simultaneous ascent/descent of a lifting/lowering cord suspended and supported ahead of and in the rear of a slat.SOLUTION: In a slat lifting/lowering apparatus for a horizontal blind, a lifting/lowering cord suspended from each of a plurality of winding shafts rotatably supported in a head box is suspended ahead of and in the rear of a slat, and a rotational-direction conversion device for concurrently winding or unwinding the lifting/lowering cords by rotating the winding shaft suspending the lifting/lowering cord on the indoor side of the slat and the winding shaft suspending the lifting/lowering cord on the outdoor side of the slat in directions opposite to each other on the basis of rotation of a drive shaft is provided between the drive shaft and each of the winding shafts. Rotation conversion devices 13 and 14 are configured by meshing bevel gears together. |
