ABSTRACT:
In the sensor: torsion beams 7a, 7b are fixedly connected between the centers of opposite outer sides of central fixed board 1 and the corresponding centers of opposite inner sides of a window 5; electrodes 11a, 11b, 12a, 12b are mounted on a front and a rear surface of weight portions 9a, 9b; and, an outer cover 21, which is constructed of an upper and a lower board 17, 19 provided with electrodes 23a, 23b, 25a, 25b corresponding to the electrodes of the weight portions, is mounted on a side surface of an outer frame 15 in which both the central fixed board 1 and the weight board 3 are received, so that the central fixed board 1 is rotatably supported. It is possible to increase the length of each of the torsion beams 7a, 7b. These electrodes 11a, 11b, 12a, 12b may be produced through a single path in printing process.
