A steering device smoothly moves a variable tilt lock gear in a tilt direction, smoothly engages the movable tilt lock gear with a stationary tilt lock gear, and facilitates the assembling. When a movable tilt lock gear is not well engaged with a stationary tilt lock gear, and the respective threads of a gear of the movable tilt lock gear and a gear of the stationary tilt lock gear are abutted against each other, arm parts of a wire spring are elastically deformed by its reaction force. As a result, the movable tilt lock gear is slightly moved in the vertical direction of the vehicle body while the stationary cam is fixed, and the gear of the movable tilt lock gear and the gear of the stationary tilt lock gear are normally engaged with each other.
