A tongue (67) is provided, at a front end thereof, with a drop-loop preventing step (79), and the hook (11) is provided, on an outer edge portion thereof extending from a sharp-pointed tip (27) of the hook to a top (29) of the hook, with a loop escape surface (31) to hide the drop-loop preventing step (79) when the hook (11) is closed by the tongue (67). In addition, the front end of the tongue is lowered so that a height between a bottom of the needle body and a top of the drop-loop preventing step (79) is lowered more when the slider is in a knock-over position than before the slider arrives at the knock-over position and also the top of the drop-loop preventing step (79) positioned at the knocked-over position can be positioned at a lower level than the top (29) of the hook. This can allow a further smooth knock-over of the loop without negative effects on the yarn feed requirements for the capture of the yarn by the needle hook. <IMAGE>
