<P>PROBLEM TO BE SOLVED: To provide a lifting jig that can achieve high work efficiency by enabling a tilting operation to be easily performed in a lifted state. <P>SOLUTION: The lifting jig 3, which is interposed between a lifting and lowering member and a member (agitating blade) to be lifted, includes a locking part 4 for being coupled to the lifting and lowering member J, and a support part 5 for being coupled to the member to be lifted. The locking part 4 includes a frame 4a in which an arc-shaped guide part 4c is formed. The arc-shaped guide part 4c, which is elongated downward from a position above a central point in such a manner as to be located along an arc corresponding to the one central point, supports the member to be lifted. The support part 5 and the arc-shaped guide part 4c have shapes and dimensions determined so that the center G of gravity of the member to be lifted can agree with or get closer to the central point of the arc-shaped guide part when the member to be lifted is attached to the support part 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
