PROBLEM TO BE SOLVED: To provide a winding spring adjusting device for a mesh or planar screen, which allows a rocking lever with a claw to elastically and strongly press-contact with a ratchet of a central gear, and stably holds the press-contact state, to thereby facilitate minute adjustment of the winding spring, particularly to a weaker level. SOLUTION: In the mesh or planar screen winding device, a substrate having a peripheral wall and an opening in a front surface, and a base plate superposed on an upper or lower side of the same, are fixed to an upper edge of a storage frame, and a central gear having a central shaft thereof rotatable in one body, is axially supported in a space between the substrate and the base plate. The central gear is a composite gear consisting of a large gear and a ratchet gear. Further the space has installed therein a coiled compressive spring which axially supports a driving small-diameter sub-gear in mesh with the large gear of the central gear, and the rocking lever with the claw, engageable with the ratchet gear, and energizes the rocking lever so as to engage with the ratchet gear. Further the substrate has formed therein a storage chamber in which the compressive spring is directly storable, and a proximal end of the rocking lever has formed therein a pressing button exposed to the opening.
