PROBLEM TO BE SOLVED: To provide a rotary type component force measuring instrument capable of finding component force precisely. SOLUTION: This instrument is provided with a rotary type component force detector 11 integrally formed with the second I-shaped cross-section type sensing beam 15 for connecting a rim attaching frame 12 and a hub attaching frame 13 to the attaching frame 12, 13, and the first sensing beam 16 for connecting the second sensing beam 15 to the attaching frame 12, orthogonal shearing type strain gages A1-H4 are bonded respectively onto obverse and reverse faces of sensing parts, signals from the strain gages A1-H4 are read out respectively from a bridge circuit in every of the sensing parts, output signals from the bridge circuits are sampled by an electronic circuit arranged inside a rotary part, in response to timing signals from rotation angle detection signals, the output signals are transmitted to a signal processing part 33 arranged outside the rotary part by a noncontact data transmission method, and 6 component forces are calculated in the every rotation angle, by correcting the output signals by preliminarily stored correction information in every rotation angle position of the detector 11, and by conducting coordinate transformation.
