Abstract
A position detection device for detecting a position of a rack shaft having a rack teeth portion that meshes with a pinion gear in a part in an axial direction, is provided with a capacitance member that is arranged around a periphery of the rack shaft and forms a capacitive load together with the rack shaft, and a calculation unit that calculates the position of the rack shaft based on a capacitance between the rack shaft and the capacitance member. The capacitance member is arranged to face at least a part of the rack teeth portion. The capacitance changes in accordance with the position of the rack shaft.
