First and second lifting and lowering units (21, 22) are connected to first and second shielding members hung from a head rail (13), and a single operating cord (14) drives the first and second lifting and lowering units to lift and lower the first and second shielding members independently. A rotating member (26) is attached to the head rail, and the operating cord is wound around the rotating member. Between a first input shaft (21a) to which the turning force of the rotating member is transferred and a first output shaft (21b) that can lift and lower the first shielding member, a first clutch (31) of the first lifting and lowering unit is provided, and a first stopper (41) is provided in the first output shaft. Between a second input shaft (22a) to which the turning force of the rotating member is transferred and a second output shaft (22b) that can lift and lower the second shielding member, a second clutch (32) of the second lifting and lowering unit is provided, and a second stopper (42) is provided in the second output shaft. A solar radiation shielding apparatus of the present invention lifts and lowers the first shielding member and the second shielding member independently with a relatively simple structure with operation of one operating cord.
