Abstract
A strain body of a force sensor according to the present invention includes a tilting structure disposed between a force receiving body and a support body, a force-receiving-body-side deformable body connecting the force receiving body and the tilting structure, and a support-body-side deformable body connecting the tilting structure and the support body. The tilting structure includes a first tilting body that extends in a second direction orthogonal to a first direction and that is elastically deformable by the action of force in the first direction.

A force sensor comprising:
- a force receiving body that receives action of force or moment to be targeted for detection;
- a support body that is disposed on one side of the force receiving body in a first direction and that supports the force receiving body;
- a strain body that connects the force receiving body and the support body and that is elastically deformed by the action of force or moment received by the force receiving body;
- a detection element that detects displacement caused by elastic deformation produced in the strain body;
- and
- a detection circuit that outputs an electric signal indicating force or moment acting on the strain body, on the basis of a detection result by the detection element, wherein
- the strain body includes a tilting structure disposed between the force receiving body and the support body, a force-receiving-body-side deformable body that connects the force receiving body and the tilting structure, the force-receiving-body-side deformable body being elastically deformable by the action of force or moment received by the force receiving body, and a support-body-side deformable body that connects the tilting structure and the support body, the support-body-side deformable body being elastically deformable by the action of force or moment received by the force receiving body, and
- the tilting structure includes a first tilting body that is disposed in a plane including the first direction and a second direction orthogonal to the first direction, the first tilting body extending in a direction different from the first direction and being elastically deformable by the action of force in the first direction.
