PROBLEM TO BE SOLVED: To absorb an assembly error or a thermal expansion difference between a vehicle-body-side frame and a tank; to perform accurate measurement without being affected by them; and further to suppress an increase in height or increase in weight and make it easy to assemble the load cells into a vehicle by building load cells into a vehicle body. SOLUTION: On-vehicle weight measuring instruments of this invention are disposed on a front part and on a rear part, respectively, of a vehicle body, and between the vehicle-body-side frame and the tank mounted on the vehicle-body-side frame. The measuring instruments are equipped with load cells. At least one of the load cells is made as an axial pin-shaped load cell by being equipped with a weight loaded part axially in the middle of an axial elastic body while being equipped with supports parts on both the sides, being equipped with strain parts causing shear strains between the loaded part and the support parts, and being mounted with strain gauges on the strain parts. The pin-shaped load cell is mounted via a bearing on the vehicle-body-side frame axially slidably and rotatably. COPYRIGHT: (C)2007,JPO&INPIT
