ABSTRACT:
A seat weighing device which is not readily affected by the heat, as well as maintaining stable sensitivity of a load sensor. Four deformation resistors are disposed on a sensor plate with the same distance from the center of a fastening member. Furthermore, four openings are formed at positions near the fixing positions (mounting positions) for the two deformation resistors on the sensor plate. The formation of these openings, reduces the cross-sectional area at positions where the openings have been formed on the sensor plate, and thus, the sensor plate readily flexes (deforms) at a position around the fixing positions for the deformation resistors. This enables the deformation resistors, to measure the load in a sure manner.
