The lens includes: a first protrusion having a first contact surface in contact with one surface of the base assembly and a second contact surface formed at a different height from the first contact surface and being in contact with the other surface of the base assembly; and a second protrusion spaced apart from the first protrusion and having a third contact surface in contact with one surface of the base assembly. The lamp unit of the present invention can prevent the lens from being pushed or separated from a substrate and prevent the lens from shaking on a substrate. |
