In case of usual gearing, it is possible to know the meshing condition of the gear by measuring the strain on the root of the tooth. However, it is impossible to stick a strain gauge on the root of the tooth, because the module is too small in case of the strain wave gearing. Therefore, in this study, the space was cut off at the rim part of the circular spline, which was one of the components of the strain wave gearing, by the electric discharge machine, and the strain gauge was stuck there. The consideration on the simultaneous meshing number of teeth was carried out with the measured value of the strain on the root of the tooth got by load tests using this special strain wave gearing. The results showed that 18% of all teeth meshed simultaneously in case of the no-load torque and that 34% of all teeth meshed simultaneously in case of the rated load torque.
