The clamp includes a spring supporting member and a pressure member which clamp the laminated leaf spring assembly therebetween. The apparatus further comprises a hydraulic cylinder for pressing the pressure member to urge the laminated leaf spring assembly against the spring supporting member. The pressure of a pressurized fluid supplied to the hydraulic cylinder is controlled by a control valve of a hydraulic control member. The operating pressure of the control valve is controlled by detecting values of predetermined factors of a body to be supported by a detector and supplying predetermined signals to the control valve in accordance with the detected values.
