PROBLEM TO BE SOLVED: To provide a static unbalance measuring instrument which is more simple and inexpensive.SOLUTION: A static unbalance measuring instrument 10 comprises a center pin 11, first beam member 12 to fourth beam member 15 extending radially from the center pin 11, a first a platform balance 16 having a tip of the first beam member 12 or a tip of the second beam member 13 mounted thereon to measure mass, a second platform balance 17 arranged symmetrically with respect to the first platform balance 16 centering on the center pin 11 to have a tip of the third beam member 14 or a tip of the fourth beam member 15 mounted thereon to measure mass, and an operation part 18 for operating an unbalance amount and an unbalance position on the basis of the mass measured by the second platform balance 17 and the mass measured by the first platform balance 16. The platform balances can be diverted as a commercial item, and a commercially available personal computer sufficiently serves as the operation part. Then, according to this invention, a static unbalance measuring instrument being more simple and inexpensive is provided. |
