Patent ID: 11402285

Abstract:
The invention relates to a force sensor 100 that detects a force acting from the outside, and provides the force sensor 100 whose reduction in size and cost can be achieved. The force sensor 100 includes a support member 20, a force receiving member 4 that is displaced with respect to the support member 20 by the action of an external force, an elastic connection member 5 connecting the support member 20 and the force receiving member 4, scales 8a to 8d, which are detection target object bodies, disposed at the elastic connection member 5, displacement detection elements 9a to 9d that are mounted on the sensor substrate 7 composing the support member 20 so as to face the scales 8a to 8d in a one-to-one manner, and that detect movements of the scales 8a to 8d.
