<P>PROBLEM TO BE SOLVED: To stabilize more the condition of holding/fixing a pipe material by a holding member. <P>SOLUTION: Pinions 159, 161 gearing with an internal gear 175 are rotated to a base plate 157 by rotating an internal gear 175 to a base plate 157. By this rotation, moving plates 163, 165 which have plating racks 163b2, 165b2 which gear with pinions 159, 161 are made to mutually move to approach, thereby a pipe material is held and fixed by rollers 167, 169 which moving plate 163, 165 support individually. In this condition, an external tooth 175b of an internal gear 175 is made to engage with a lock claw 185 formed at a slide bar 187 which can move along a cylindrical part 183 of a base plate 157 circumference, thereby moving in a direction of moving plates 163, 165 which separate from each other through pinions 159, 161 and plating racks 163b2, 165b2 by rotation of an internal gear 175 is regulated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
