Abstract
A steering lock device includes a position detector that detects a position of a lock member. The position detector includes a first unlock detecting portion of a digital output type that detects that the lock member is located in an unlock position and a second unlock detecting portion of an analog output type that detects that the lock member is located in an intermediate position, which is between a lock position and the unlock position. A position determination portion determines whether or not the lock member is located in the unlock position based on a detection signal of the first unlock detecting portion and a detection signal of the second unlock detecting portion, which has a parabolic output waveform that changes in accordance with movement of the lock member.
