Abstract
A sunlight-shielding device includes two one-way clutches characterized by a short overall length, compact size, simple structure, and fewer parts for a sunlight-shielding device in which two shielding materials suspended from a head box can be switched using a single-loop up/down operation cord. Each one-way clutch includes has an input disk, input plate, top plate, and output drum provided on a center pin in a rotatable manner such that when the input plate rotates in a specified direction due to the rotation from the input disk, an engagement part of the top plate projects along a guide groove and engages with an engagement projection strip of the output drum, to transmit the rotation from the input disk to the output drum.
