A weft of each rung of a ladder cord is formed of two weft threads, an intersecting portion is formed in the weft threads, a slat is inserted between the intersecting portion and one of warp threads of the ladder cord, and a lifting and lowering cord is inserted between the weft threads at a location between the intersecting portion and another of the warp threads.

An operation apparatus of a sunlight shielding apparatus is provided which is equipped with a fail-safe function so as not to hinder behavior of a dweller or the like, and, in usual operation, unnecessary activation of the fail-safe function is prevented, so that enhanced operability can be realized. In a sunlight shielding apparatus in which an operation cord of an endless type is suspended from a pulley supported so as to be capable of rotating in a head box, and a driving shaft is rotated based on an operation of the operation cord by way of the pulley so as to drive a shielding member, the operation cordis made into an endless type by coupling via a coupling section which is configured to be decoupled with a predetermined first pull force, and a torque limiteris interposed between the pulleyand the driving shaft, the torque limiter being configured to run idle with a second rotation torque which is smaller than a first rotation torque which is exerted on the pulley by the first pull force.
