Abstract
The torque sensor of the present invention converts the torsion of a shaft into an amount of movement of a slider member and detects the amount of movement of the slider member as a variation in the self-inductance of a detection coil unit. The detection coil unit is a bobbin having a coil wound thereon. The bobbin has a cylindrical portion, first and second annular flange portions provided on axially opposite ends of the cylindrical portion, and a third annular flange portion provided between the first and second flange portions. The coil is wound on a second groove defined between the second and third flange portions. An end portion of the coil is connected and fixed to a lead wire (connected to a detection circuit unit) in a first groove defined between the first and third flange portions. The diameter of one of the flange portions of the detection coil unit can he larger than the diameter of the other flange portions to prevent improper assembly of the detection coil unit.
