Abstract
A pillow type pressure detector having a base board on the front surface of which a load cell type load sensor is mounted; a holder cover which is so provided as to be spaced a predetermined distance from the base board; a flat-plate-shaped load transmitting board and a flat-plate-shaped retaining board positioned between the base board and the holder cover; a pillow type pressure reaction jig positioned between the load transmitting board and the retaining board; and a pillow holding member for clamping predetermined portions of the pressure reaction jig mounted over the base board and the holder cover. There are provided a mechanism for simultaneously swinging the load transmitting board and the retaining board relative to the base board, a mechanism elastically supporting the pillow holding member on the side of the base board and/or a thin-plate-shaped depressing member provided over the surface of the load sensor for fixedly secure the load sensor to the base. Distortion resulting from setting of the pressure detecting element is eliminated and accuracy of detection is improved.
