    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).
