PROBLEM TO BE SOLVED: To provide a dynamic characteristic measuring device capable of accurately measuring dynamic characteristics of an engagement point of a planetary gear mechanism.SOLUTION: A dynamic characteristic measuring device 100 measures dynamic characteristics of a planetary gear mechanism 50, and includes: a carrier support tool 130 for supporting a carrier 61 instead of a case 70; a counter drive support tool 140 for supporting a counter drive 62 instead of the case 70 via a bearing 71; a counter driven gear 55 engaged with a counter drive gear 54; a drive motor 110 for driving the counter driven gear 55; a load motor 120 pivotally supported by a sun gear 52; a carrier displacement sensor 151 for detecting the displacement of the carrier 61; a counter drive displacement sensor 152 for detecting the displacement of a counter drive 62; and a controller 150 for calculating a relative displacement for the counter drive 62 of the carrier 61. |
