Abstract
The present invention discloses a winding device that includes a screen, a shaft portion to which one end of the screen is fastened, a rotary shaft member that fits to an end portion of the shaft portion so that the rotary shaft member is rotated around a rotation axis along an axial direction of the shaft portion, and a biasing portion that biases the rotary shaft member in a rotation direction for winding the screen. A relative rotation restriction structure and a movement restriction structure are formed on a fitting portion between the shaft portion and the rotary shaft member. The relative rotation restriction structure restricts a relative rotation of the shaft portion with respect to the rotary shaft member. The movement restriction structure restricts a movement of the shaft portion in the axial direction with respect to the rotary shaft member.
