Lamp module for vehicle and lamp for vehicle including the same

A lamp module for a vehicle, comprising:

• a first light source configured to output light and having a first optical axis;
• and
• a light guide part disposed in front of the first light source and configured to receive the light output from the first light source, the light guide part including:
• a lower surface;
• a first recessed area recessed upwardly from the lower surface;
• a rear light guide section comprising a rear surface facing the first light source, wherein the first optical axis extends through the rear surface, and the rear surface has a second optical axis traversing the first optical axis;
• and
• a front light guide section disposed in front of the rear light guide section,
• wherein the rear light guide section further comprises an upper surface including a total reflection portion configured to reflect, toward the front light guide section, a substantially entire portion of the light output from the first light source and transmitted to the light guide part via the rear surface,
• wherein the front light guide section is configured to externally output the substantially entire portion of the light reflected by the total reflection portion toward the front light guide section to form a light distribution pattern,
• wherein the first recessed area is configured to shield a portion of the light output from the first light source to form a beam pattern, and
• wherein the rear surface of the rear light guide section has a vertically and horizontally symmetrical shape.
