Abstract
The wiper device for a sewing machine having a wiper member swingable from the operating position to a non-operating position on an embroidery presser foot, in which a needle thread-end is retained by being clamped between a frictional-resistance applying member fixed to an underside of a thread engagement portion located on a distal end of the wiper member and an upper surface of a cloth presser pressing a workpiece cloth by a returning movement of the wiper member from an operating position in which the wiper member performs a thread wiping operation to a stand-by position.
