Abstract

PURPOSE:To make the pitch of a different feed pitch feedable at a driving part for a single setting feed stroke, by installing a roller being variable for its setting position to a feed lever rocking fulcrum and rocking together with the feed lever and an engager engaging the roller in the axial direction of a feed shaft. CONSTITUTION:When a feed pitch 13 is rotated, an auxiliary feed lever 15 and a main feed lever 20 rock in a fixed angular range whereby a feed shaft 29 is fed in pitch in its axial direction via an engager engaging a roller 24 to be rocked together with the the main feed lever 20. This feed pitch is determined with both of a rocking angle of the main feed lever 20 and a setting position of the roller 24 in relation to a support pin 19 of the main feed lever 20. Therefore, when this feed pitch is changed, it is simple enough to do the following process that a screw shaft 26 is rotated by operation of a control knob 25 and a slider 23 is moved along both guide parts 22 of the main feed lever 20, then the setting position of the roller 24 to the support pin 19 is adjusted.
