PURPOSE: A spring adjuster of an automatic winding slide mosquito net window is provided to optionally adjust the tightness and the looseness of the spring in high speed while adjusting the loosing speed and the loosing degree of a spring adjustment unit in the adjustor. CONSTITUTION: A spring adjuster of an automatic winding slide mosquito net window contains a spring adjustment unit(3) integrated with a large diameter sprocket(1) and a small diameter ratchet gear(2) and combined with one end of a spring supporting shaft through a key groove type shaft hole(4). A click(6) is formed at the left lower end of the spring adjuster and engaged with a gear(5) of the small diameter ratchet gear. An adjusting piece(8) with a driving protrusion(7) is supported in both grooves(10,10') inward a housing(9) of the spring adjustment unit with the elasticity of a compression spring(11). At the same time, the adjusting piece is horizontally moved according to the movement of the driving protrusion. To tighten a spring, a gear(12) of the large diameter sprocket is rotated rightward. To loose the spring, the adjusting piece is pushed to the left by the driving protrusion and the click is released from the gear of the ratchet gear to rotate the ratchet gear leftward.
