Abstract
A load detection sensor capable of stably weighing a heavy object to be weighed in high precision. The load detection sensor according to the present invention includes a force sensor including a tuning fork vibrator and a block body that has a rectangular parallelepiped outer shape and transmits an applied load to the force sensor by using a lever to reduce the load. It is characterized in that the block body contains therein a lever mechanism and a Roberval mechanism by working on the longitudinal side thereof and that the force sensor is coupled to the side of the block body. Although the block body is cut and ground in the side for fabricating the lever mechanism and the Roberval mechanism, it maintains the rectangular parallelepiped outer shape and sufficient mechanical strength, thereby enabling to stably reduce the applied load.
