Abstract:
A torque detector for detecting a torque acting mutually between a first shaft and a second shaft arranged end to end on a common axis, comprising:a plurality of elastic rods, secured at each end to a facing end of said first shaft and a facing end of said second shaft such that said rods are individually able to twist in response to said torque;at least one movable element with wings, wherein said at least one movable element is secured to and spans two of said elastic rods and is displaced radially inwardly and outwardly with respect to said common axis in response to the twisting of said elastic rods;and detection means, disposed so as to face said wings radially to said common axis and which generates a magnetic flux in a magnetic circuit which includes said wings and detecting said radial displacement of said wings as electromagnetic change.
