Abstract: The present disclosure relates to a clothes folding device including: a loading assembly which causes the clothes to be pushed-in and seats the clothes on a first folding layer equipped with a conveyor for transport; a folding assembly which performs the folding of the clothes while the pushed-in clothes are transported; and an unloading assembly which is disposed below the folding assembly and loads the clothes discharged by the folding assembly. The loading assembly includes: a seating plate which forms an inclined surface at an inlet and allows the clothes to be seated thereon; a clamp assembly which fixes the clothes and moves the clothes to the first folding layer; and a transport roller which presses the clothes seated on the first folding layer and rotates together with the moving of the clothes while pressing the clothes, and thus, preventing the clothes from being separated. The clamp assembly includes a wheel assembly and a clamp plate which presses inserted clothes from both sides. The wheel assembly includes a unidirectional rotating wheel which rotates together with the inserted clothes.
