PROBLEM TO BE SOLVED: To provide a shielding material transfer device of an electric solar radiation shielding apparatus that can smoothly and stably transmit driving force of a motor to a conveyor belt for transferring a runner.SOLUTION: In a shielding material transfer device of an electric solar radiation shielding apparatus; pulleys are each rotatably supported on transfer devices which are installed at both ends of a rail; a belt can be transferred in the rail on the basis of the rotation of the pulleys; a motor unit is installed in at least either of the transfer devices to rotatably drive the pulleys; and runners are transferred along the rail with the belt transferred based on the rotation of the pulleys. The pulley 13 is rotatably supported through one bearing 12 on a shaft part 11 provided in the case 7 of the transfer device 5b. The belt 14 is supported in a manner immovable in the axial direction of the pulley with a flange 16 installed on one side in the axial direction of the pulley and with a sleeve 21 arranged on the other side in the axial direction of the pulley. In the case, there is provided a guide wall 15 which guides the belt to the position to be put on the pulley. |
