- the first guide is formed by connecting a plurality of first guide units, each of which is arranged in a Y direction when the first guide is pulled out from the inside of the slidable stile.
- the first guide includes a pair of side walls arranged to face each other in the axial direction and a bottom wall connecting the side walls.
- the first guide unit is pivoted to the first guide unit, and this pivot allows the first guide to bend in the other Z-axis direction while maintaining linearity in the X-axis direction. It is known that one end in the Z-axis direction of an unfolding screen is inserted between both side walls of each first guide unit in the guide portion (see Patent Document 1, for example).

- each first guide unit is generally an integrally molded product made of resin, and as the screen is deployed and retracted, it repeatedly sticks into and comes off from one end of the screen in the Z-axis direction.
- rigid projections have problems such as being bent and deformed, or being broken and damaged.
- the type of screen is generally changed depending on the application, installation location, and the like of the screen device. Therefore, if the molding material of each of the first guide units is stronger than the screen, there is a risk that one end of the screen in the Z-axis direction will be damaged when the rigid projection pierces the screen.
- the applicant of the present invention can suppress damage to one end of the screen in the Z-axis direction on the side of the screen inserted into the first guide even by repeating deployment and retraction of the screen, and at the same time, regardless of the type of screen, proposed a screen device capable of forming a first guide only with a first guide unit of the type (Japanese Patent Application No. 2020-038505 (unpublished)).
