A blind apparatus comprises a first link mechanism, a second link mechanism, slat supporting mechanisms, slats (9) respectively supported by the slat supporting mechanisms, a raising and lowering mechanism (10) for the slats, and a tilting mechanism for tilting the slats. The link mechanisms have flexible belt-shaped bodies and shaft members connected to one end portion (39) of each of the arm members. A blind apparatus comprises a first link mechanism; a second link mechanism; slat supporting mechanisms each having one end portion connected to the first link mechanism and another end connected to the second link mechanism; slats respectively supported by the slat supporting mechanisms; a raising and lowering mechanism for raising and lowering the slats; and a tilting mechanism for tilting the slats by causing the first and the second link mechanisms to undergo relative positional changes as the slats are raised or lowered by the raising and lowering mechanism. Each of the slat supporting mechanisms has an arm member for supporting an end portion of the slat at a central portion of the arm member. The first link mechanism has a flexible belt-shaped body and shaft members to which the belt-shaped body is secured and which are rotatably connected to one end portion of each of the arm members. The second link members have a flexible belt-shaped body and shaft members to which the belt-shaped body is secured and which are rotatably connected to another end portion of each of the arm members. |
