Abstract: A window winder including: a body (2) having a housing (3) and a base plate (5) which when assembled together enclose an inner volume (7), the base plate having an elongate opening (13) therein; a chain (9) accommodated within the inner volume; a drive means (29) for respectively extending the chain (9) from and retracting the chain back into the body (2); a displaceable guide member (11) located within the inner volume (7) for guiding the chain during extension or retraction of the chain; and an abutment means (15) locatable on the guide member (11); wherein the abutment means (15) can be located in an extended position on the guide member (11), such that the movement of the guide member (11) when the chain is being extended is limited by the abutment means (15) abutting a peripheral edge (14) of the elongate opening (13) to thereby limit the maximum extension of the chain (9) from the body (2). 27 29 25 1A 3 7 9 1 1 15 ........ .....................
