Abstract:
1. A diaphragm type load detection sensor comprising: a mounting portion attached to an installation plate; a strain generation portion provided on the mounting portion and having a load applied portion formed at the center thereof to which a load to be detected is applied; and a strain gauge provided on the strain generation portion, wherein said strain gauge has sensing elements evenly provided on substantially a whole periphery thereof and positioned at predetermined distances from the center axis of the load applied portion of the strain generation portion; a projection is formed on the load applied portion at the center axis thereof and said sensing elements are provided on a surface of the strain generation portion at such side that is opposite to the side where said projection is formed; said sensing elements have a pattern wherein the sensing element is disposed to receive a strain in the peripheral direction and a pattern wherein the sensing element is disposed to receive a strain in the radial direction; and said mounting portion is attached to the installation plate with a flexible resilient member interposed therebetween.
