A load detection structure provided between a vehicle seat and a support leg element to be fixed on a floor. The load detection structure includes a strain plate member pivotally provided within the support leg element and connected at the one end portion thereof with the vehicle seat. Such one end portion is sandwiched between two reinforcement plates, whereas another portion of the strain plate member is formed with an half hinge portion extending transversely thereof. A hinge plate having a half hinge portion is attached to that another end portion, thus defining a through-bore therein, and a hinge pin is inserted in the through-bore, so that the hinge or pivot point of the strain plate member is made small in heightwise thickness. Upper and lower stopper pieces for limiting vertical deflection of the strain plate member are formed in each of two vertical walls of the support leg element.
