Abstract: A small-sized load sensor unit including a pressure member, to which a pressing force is applied, a strain body which is fixed to the pressure member by a first fixing member, a strain measuring unit which is provided on the strain body and is configured to be deformed together with the strain body, a first restricting unit which restricts a pressing force applied to a substantially center portion of the pressure member such that the pressing force becomes a predetermined threshold value or less, and a second restricting unit which restricts the pressure member from moving by a predetermined amount or more when a pressing force of an excessive load is applied to an edge portion of the pressure member.

Abstract: There is provided a load sensor including: a pressing shaft configured to transmit a load in an axial direction of the pressing shaft; a sensor element configured to measure the load being transmitted by the pressing shaft; and a load limiting means configured to limit the load applied to the sensor element and protect the sensor element from being applied with excessive load, the load limiting means being configured to be deformable by the load when the load transmitted by the pressing shaft exceeds an allowable measurement range set for the sensor element.
