STEERING LOCK DEVICE

A steering lock device (1) includes a trigger (70) that is displaced as a frame cover (20) drops from a frame (10), an auxiliary lock device (60) that holds a lock member (50) in a locked position as the trigger (70) is displaced under condition that the lock member (50) is positioned in the locked position, housing components (30, 35) that are arranged in a housing chamber (13) defined by the frame cover (20) and the frame (10) or in a guide hole (14), and a trigger coupling member (73) that couples the housed components (30, 35) and the trigger (70). When the housed components (30, 35) are displaced, the trigger (70) is displaced via the trigger coupling member (73).
