Claims

[Scope of utility model registration request]

a strain-generating portion that is elastically deformed by an external force;
In a force detector having a strain gauge that detects the elastic deformation of the strain-generating portion and measures the magnitude of force, the strain gauge is provided on an outer peripheral side surface and an outer peripheral slope that constitute the outer peripheral surface of the strain-generating portion, respectively. while measuring forces in two mutually different directions, and forming a groove-shaped gap in the strain-generating portion to facilitate elastic deformation.
A force detector characterized in that wall surfaces forming the gap are in contact with each other to prevent deformation greater than the gap amount of the gap.
