The invention relates to a chainwinder comprising a housing formed by a body and a metal base, to receive a chain therein; a drive mechanism engageable with the chain, to selectively drive the chain from the housing to alter the degree of openness of an attached window, the drive mechanism including at least one drive gear rotatable about an axis extending between respective ends of the drive gear, the drive gear being mounted relative to the body at a first end portion and mounted relative to the base plate at a second end portion; and a wear component mounted between the base and the second end portion of the drive gear. The invention is particularly suitable for heavy duty chainwinders, and reduces the wear on the drive gear relative to conventional chainwinder designs, enabling a longer functional life. ~rW r'~oZIA ~"X\ AW" SOO~ ' ANg & A'.'
