<p><P>PROBLEM TO BE SOLVED: To enable suspension in an intended direction by mounting a suspension ring part which is rotatable right, left and all around, on a hole-suspension jig. <P>SOLUTION: The hole-suspension jig 10 including a body 11 provided with a workpiece insertion opening 13 opening downward a cross a pair of legs 12a and 12b, and a suspension pin 14 disengageably extending a cross the pair of legs of the body is structured to suspend the workpiece in a manner that an end of the workpiece is inserted into the workpiece insertion opening of the body in the state that the suspension pin is inserted into a hole penetrating the end of the workpiece. In the hole-suspension jig 10, a rotary rod 35 is mounted on the body to be freely rotatable all around, and a suspension ring 27 is fitted to be freely rotatable right and left around a suspension ring bolt 41 penetrating a shaft hole (39) of the rotary rod. As an example, a tapered surface (37) formed on the lower end of the rotary rod is made to be freely rotatable all around while bringing the same into slide contact with a tapered surface (34) of the inner diameter space (33) of a rod fitting member 29 embedded in and fixed to the body (Fig.6, Fig.7). <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
