1. A load detecting device for a vehicle seat comprising:

  • a supporting base adapted to be mounted on a floor of the vehicle;

    a plurality of load sensors including at least one pair of front and rear load sensors arranged along a forward and backward direction of a seat for the vehicle on the supporting base, each of the load sensors including;

    a load input portion;

    a deflection portion that deflects in response to a load transmitted from the load input portion; and

    a deflection gauge that measures an amount of deflection generated at the deflection portion, the load sensors detecting the load based on the amount of deflection measured by the deflection gauge;

    a connecting member connecting the load input portions of the at least one pair of front and rear load sensors;

    a seat supporting member formed separately from the connecting member and connected to the connecting member, the seat supporting member adapted to support the seat and transmit load applied to the seat to the connecting member; and

    a stopper formed separately from and disposed between the at least one pair of front and rear load sensors, and that prevents deformation of the connecting member at least in a vertical direction of the seat when load exceeding a predetermined value is applied to the connecting member.
