Abstract
An external gear includes a body, external teeth, a diaphragm, and a strain gauge. The diaphragm extends in a direction intersecting with an axial direction on another side in of the body the axial direction. The strain gauge is on at least one of a surface on one side of the diaphragm in the axial direction and a surface on another side of the diaphragm in the axial direction. The strain gauge is only in a region that is about a half or less of a radial length from one end of the diaphragm in the axial direction to the other end of the diaphragm in the axial direction with a radial midpoint between the one end of the diaphragm in the axial direction and the other end of the diaphragm in the axial direction as a center in a section passing through the central axis.
