An injury reducing steering tilt column structure of a vehicle is provided to allow the chest of a passenger to make surface-contact with a steering wheel by reducing the tilt angle of a column through a height adjusting unit. An injury reducing steering tilt column structure of a vehicle includes an air bag control unit(10), a tilt lever releasing unit(20), a guide bar(30), and a height adjusting unit(40). The air bag control unit detects a collision condition during a test. The tilt lever releasing unit releases a tilt lever(21) under the collision condition by using the explosive force of gunpowder. The guide bar allows the angle of a tilt column(31) to be easily regulated. A coil spring(41) is provided in the height adjusting unit. Therefore, the structure reduces the tilt angle of the column during a collision of the vehicle.
