Load sensor and electromechanical brake system

Abstract

A load sensor used in an electromechanical brake system is provided. The load sensor includes a flange member capable of deflecting when receiving, at a load receiving portion, a load from the axially front side; a support member capable of supporting the flange member from the axially rear side, at a support portion displaced from the load receiving portion in a radial direction orthogonal to the axial direction; a displacement detecting mechanism configured to detect the amount of relative movement between the flange and support members; and a variable detection sensitivity mechanism enabling the relative movement amount with respect to the change of the load applied to the flange member to be larger in a low load range in which the load is equal to or lower than a predetermined load value than in a high load range in which the load is higher than the predetermined load value.
