A seat weight measuring apparatus capable of estimating with higher precision the weight and the center of gravity of a passenger on the seat and with reduced cost. A seat weight measuring apparatus 9 comprises a load cell 50, a connecting mechanism 15, which connects a seat 3 and the seat fixing portion 13 of the vehicle body, and a transmitting mechanism 16 which transmits the action of the seat weight on the connecting mechanism 15 to the load cell 50. In the transmitting mechanism and the connecting mechanism, arms 23 pivotally supported by horizontal pivots 31 so that the arms 23 can pivot about the pivots 31. Actions according to the pivotal movements of the arms are transmitted to a load cell 50. Loads on the front side portion and the rear-side portion of the seat are each measured by one center load cell 50.
