Abstract
To provide a seat weight measuring apparatus capable of improving the safety against an abnormal force acting on the seat. A seat weight measuring apparatus (5) includes seat connecting mechanisms (17) arranged between seat fixing portions (19) of a vehicle and a seat (3), and load sensors (13) which detect the seat weight loaded on the mechanisms. It further includes displacement restriction mechanisms (25) that restrict the displacement of the seat (3) relative to the seat fixing portions (19). When the load sensors receive a force exceeding a predetermined level, the excess load is borne by the displacement restriction mechanisms instead of the load sensors.
