PURPOSE:To minimize the machining while eliminating the waste of material, by building up a strain gauge sticking section of a pair of plate bodies. CONSTITUTION:A straingauge sticking section 11 is made up of a pair of plate bodies 12 parallel with each other mounted on a support section 9 at one end thereof while a force applying section 10 at the other end thereof. A straingauge 13 is stuck on the one plate body 12. When an object to be measured is placed on a tray mounted on a flat part 10a of the force applying section 10, the load acts on the force applying section 10 which receives a downward force so that the one pair of the plate bodies 12 composing the straingauge sticking section 11 will deform according to the load and outputted as changes in the electrical signal from a straingauge 13. This enables accurate measurement of force applied on the force applying section 10 while requiring no much time for ma chining because of the straingauge sticking section 11 made up of a pair of plate bodies 12 and also permits very inexpensive manufacture without waste of costly ultraduralumin material. |
