A windbreak for doors is provided to adjust projection of a blade according to a gap between a door and a doorframe by rotating an adjustment cap screwed at an end of an operation shaft. A windbreak for doors comprises a case(1), a blade(2), wires(7,7'), a set of rollers(8,8'), and a screwed portion(9). The blade, which is installed within the case whose lower side is open, is reciprocated at the lower side of the case by an operation shaft(3) transversely sliding from the case. The wires have one end connected to the end portion of the operation shaft that allows the other end to be connected to a front end of the blade. The rollers, spaced away from each other inside the case, are configured to guide the wires. The screwed portion is formed at a projected end of the operation shaft exposed at one side of the case, to make screw connection with an adjustment cap(10). |
