Lamp for vehicle

A lamp for a vehicle, the lamp comprising:

• a lamp housing part including an internal space configured to accommodate a light source;
• an outer lens part coupled to one side of the lamp housing part and configured to cover the internal space;
• a vibration part fixed to the outer lens part, the vibration part including:
• a polarized piezoelectric element;
• and
• a first electrode and a second electrode respectively facing two opposite sides based on a direction in which the piezoelectric element is polarized;
• and
• a cover member provided at one side of the vibration part and including a partial region facing the outer lens part with the vibration part interposed therebetween, the cover member comprising one or more vibration reduction holes;
• and
• a cover coupling member including one side fixed to the outer lens part to couple the cover to the cover coupling member,
• wherein the piezoelectric element is configured to output a sound by being vibrated by a change over time in voltage applied to the first electrode and the second electrode,
• wherein the cover member further comprises:
• a cover body facing the outer lens part with the vibration part interposed therebetween, the cover body spaced apart from the vibration part;
• and
• cover extension regions protruding from two opposite sides of the cover body toward the cover coupling member, and
• wherein the one or more vibration reduction holes is formed in the cover body.
