Abstract
A compound needle which includes a needle body having a needle hook at a front end thereof and a slider having tongues formed by overlapping two blades and with each other and is so structured that the needle body and the slider are individually movable back and forth in the state in which the blades and of the slider are supported in a blade groove formed in the needle body wherein a partition wall having thickness smaller than that of the needle hook of the needle body is formed in the blade groove and the blades and of the slider are accommodated in the blade groove to sandwich the partition wall therebetween, to thereby provide a reduced sliding resistance and a reduced degree of stretch of the blades when the blades are advanced beyond the needle hook.
