PURPOSE:To feed parts to the extent of a tip of a driver bit as well as to make automatic assembling attainable, by making a set to chuck jaws capable of chucking and rotating the parts so as to cause them to be set up. CONSTITUTION:A chuck unit 28 is connectedly installed in a driving shaft 23 of a rotary driving source 22 being liftable by actuation of a cylinder 18 so as to receive this rotation, while each chuck jaw 49 installed in this chuck unit 28 free of opening or closing is constituted into being rotatable in design. Doing as the abovemention, not only automatic assembling for parts, which are so far unable to be fed to the extent of a tip of a driver bit due to pneumatic feed, comes possible to be done but also automatic assembling for parts, which are so far unable to do it due to the lack of the driver bit, comes possible too. |
