Steering lock device

A steering lock device (1) includes a position detector (27) that detects a position of a lock member (12). The position detector (27) includes a first unlock detecting portion (27b) of a digital output type that detects that the lock member (12) is located in an unlock position from a positional relationship with a detected portion (28) and a second unlock detecting portion (27c) of an analog output type that detects that the lock member (12) is located in an intermediate position, which is between a lock position and the unlock position, from a positional relationship with the detected portion (28). A position determination portion (31) determines whether or not the lock member (12) is located in the unlock position based on a detection signal (Sb) of the first unlock detecting portion (27b) and a detection signal (Sc) of the second unlock detecting portion (27c), which has a parabolic output waveform that changes in accordance with movement of the lock member (12). 转向锁定装置(1)具备对锁定部件(12)的位置进行检测的位置检测部(27)。位置检
