Abstract
A displacement detection type six-axis force sensor. The force sensor includes a first end portion; a second end portion; an intermediate portion; a first connecting portion elastically connecting the first end portion to the intermediate portion with first three-degrees of freedom; a second connecting portion elastically connecting the second end portion to the intermediate portion with second three-degrees of freedom; a first detecting part detecting relative displacement between the first end and intermediate portions, accompanied by elastic deformation of the first connecting portion; and a second detecting part detecting relative displacement between the second end and intermediate portions, accompanied by elastic deformation of the second connecting portion. The intermediate portion and the first and second connecting portions are disposed such that a force applied to the first or second end portion is applied to both of the first and second connecting portions without propagating through the intermediate portion.
