摘要： A dynamic quantity sensor device capable of measuring a dynamic quantity at a high precision and securing insulation of a pressure sensing body easily. This dynamic quantity sensor includes a pressure sensing body composed of composite ceramics in which a material having a pressure resistance effect is dispersed on a matrix made of an electrical insulation ceramic material and a pressure receiving body having an electrical insulation characteristic and disposed on a pressure receiving surface of the pressure receiving body, wherein the pressure sensing body and the pressure receiving body are integrated with each other.

摘要： A load sensor comprises a load detecting element and a temperature compensating element. The load detecting element is made of the material and acting the load thereon. The temperature compensating element is made of the same material with the load detecting element, and made as the same dimension or similar figure with the load detecting element. The load detecting element and the temperature compensating element are arranged closely each other. Further, each of the load detecting element and the temperature compensating element comprises conductive part which is made of the same composite. The conductive parts of the load detecting element and the temperature compensating element are electrically connected to a power source in parallel each other. Difference between voltages which act on the conductive parts of the load detecting element and the temperature compensating element is detected as a equivalent of the load.

摘要： An electric power steering system (1) includes a tubular sensor housing (34) which accommodates a torque sensor (20), a gear housing (32) which accommodates a speed reduction mechanism (24), and an upper bearing (40) and a lower bearing (41) which rotatably support a steering shaft (3) on opposite sides of the speed reduction mechanism (24). The gear housing (32) includes a tubular lower housing (37) supporting the lower bearing (41), and an upper housing (36). The upper housing (36) includes an inner tube (67), an outer tube (68), and an annular connection wall (69) connecting the inner tube (67) and the outer tube (68). The outer tube (68) is press-fitted in the lower housing (37). The inner tube (67) is press-fitted to an inner periphery (72) of a lower portion (71) of the sensor housing (34), whereby the inner tube (67) has a reduced diameter. As a result, an outer ring (44) of the upper bearing (40) is tightly fitted and supported in the inner tube (67).
