## Abstract

PURPOSE: To easily and accurately measure the gravity center position of the body by providing a 1st rotary shaft and a 2nd rotary shaft which cross a perpendicular direction orthogonally at an optional point in a space and measuring the gravity center position in three-dimensional coordinates whose origin is at a fixed point on the 2nd rotary shaft where one optional end of the body to be measured is fixed from specific equations.
CONSTITUTION: The 1st rotary shaft and 2nd rotary shaft which cross the perpendicular direction orthogonally at the optional position O are provided and the rotary torque around the 1st rotary shaft at this time is denoted as T0. One end of the body to be measured is fixed at a fixed point P at a distance L1 from the point O on the 2nd rotary shaft and one turn of the body to be measured is made around the 2nd rotary shaft to detect the position where the rotary torque around the shaft becomes maximum. The angle α of rotation between this position and the 1st position where the body to be measured is fitted is detected and the rotary torque T1 of the 1st rotary shaft and the maximum rotary torque T2 of the 2nd rotary shaft are detected. Those values and the weight W of the body to be measured which is already measured are substituted in the equations to find the gravity center position (gx,gy,gz) of the measured body in the three-dimensional coordinates which has its origin at the fixed point P.
