Abstract

PURPOSE:To prevent malfunction of a torque sensor by supporting an input shaft within a housing with a radial bearing and a ball bearing of 4 contact point type and by making them, together with the torque sensor arranged on the input shaft, in a body with the housing. CONSTITUTION:A pinion shaft 3 as an input shaft consists of an upper shaft 3a and a lower shaft 3b connected via a torsion bar 5 with both shafts supported in a housing 4 by means of a ball bearing 40 and a 4 point contact ball bearing 41. A torque sensor 60 consists of an annular resistance keeping member 60a fitted over the upper shaft 3a to rotate together with the shaft 3a and with its bottom end being centered on the axis of the upper shaft 3a, and a detector holding member 61 fitted over the lower shaft 3b to rotate together with the shaft 3b with its top end surface formed as a detection probe to be in sliding contact with a point on the resistance keeping body. Since the longitudinal displacement of the input shaft is kept almost zero with the 4 point contact bearing, the torque sensor is prevented from functioning incorrectly.
