a case;

a cover coupled to the case;

a shield supported inside the case and configured to adjust a predetermined light beam pattern generated by a head lamp;

a motor configured to drive the shield;

a block disposed inside the case and the cover, and configured to rotatably support the shield and limit an angle of rotation of the shield,

wherein the shield comprises a shaft rod formed at one side thereof,

wherein the block comprises a through hole formed therein and the block is configured to allow the shaft rod to be rotatably inserted therein,

wherein the shaft rod of the shield comprises a detent, and

wherein the block comprises a guide slit and the block is configured to allow the detent to be inserted therein and to be rotated over a first predetermined angle while being guided by the guide slit.

2. The shield apparatus of claim 1 , wherein the block comprises a body part including the through hole and the guide slit formed therein, and an extending part outwardly extending from the body part and allowing the block to be fixed to the case.

3. The shield apparatus of claim 2 , wherein the extending part comprises a first extension part having a first surface in contact with the case, and a second extension part having a second surface in contact with the cover.

4. The shield apparatus of claim 3 , wherein the first and second extension parts are spaced apart from each other by a second predetermined angle.

5. The shield apparatus of claim 4 , wherein the second predetermined angle is about 90 degrees.

6. The shield apparatus of claim 4 , wherein the guide slit is formed between the first and second extension parts.

7. The shield apparatus of claim 1 , wherein the body part comprises a cutoff part formed at one side thereof, and the cutoff part guides the detent to the guide slit.

8. The shield apparatus of claim 7 , wherein the cutoff part comprises a guide surface, an outer side surface of which inclines such that the depth thereof gradually decreases toward the guide slit.

9. The shield apparatus of claim 1 , wherein the guide slit extends in a longitudinal direction orthogonally crossing the through hole.

10. The shield apparatus of claim 1 , wherein the detent comprises a protrusion.

11. The shield apparatus of claim 10 , wherein the protrusion is integrally formed with the shaft rod.
