An intermittent feed member adapted for an intermittent feed mechanism comprises a shaft provided having a plurality of individually groove portions which are formed in its outer periphery along the circumferential direction. Each of the groove portions has a bottom portion extending straightwardly. These groove portions have a rather small lead angle and are successively staggered axially so that their inside portions may communicate with one another, whereby a single helical groove is formed. |
