Vehicle lamp

A vehicle lamp comprising:

• a light source;
• and
• a light guide body configured to guide light emitted from the light source,
• wherein the light guide body has:
• a first light guide part disposed in front of the light source;
• an incidence section that is located on a base end side of the first light guide part and that is configured to cause the light emitted from the light source to enter the first light guide part;
• a diverging portion located on a tip side of the first light guide part;
• a second light guide part extending from the diverging portion toward one side in a first direction;
• a third light guide part extending from the diverging portion toward other side in the first direction;
• a first curved portion that is a portion of the second light guide part curved from the diverging portion toward the one side in the first direction;
• and
• a second curved portion that is a portion of the third light guide part curved from the diverging portion toward the other side in the first direction,
• wherein an optical path length of the second light guide part is longer than an optical path length of the third light guide part,
• the diverging portion has an oval shape in a cross section of a second direction which is perpendicular to an axial direction of the first light guide part, the oval shape being a shape in which two imaginary mutually tangent partial circles of the first curved portion and the second curved portion are connected with each other in the first direction, and the diverging portion is formed so that at least a part of a boundary between the first curved portion and the second curved portion describes a straight line, which is extending in a short direction of the oval shape, at a center part of the oval shape in a longitudinal direction of the oval shape,
• the first light guide part has an oval cross-sectional shape, which has the first direction as a longitudinal direction, from the incidence section to the diverging portion in a cross section in the second direction,
• a first light guide emitting section and a second light guide emitting section are provided on both sides of a diverging center portion where the first curved portion and the second curved portion diverge and curve in opposite directions with respect to each other from the boundary, the first light guide emitting section having a plurality of groove portions configured to emit a part of light which has been guided through the first light guide part and which has entered an upper surface of the first curved portion to an outside and the second light guide emitting section having a plurality of groove portions configured to emit a part of light which has been guided through the first light guide part and which has entered an upper surface of the second curved portion to an outside,
• the light source is disposed so that an optical axis of the light emitted from the light source is shifted toward the second light guide part with respect to a boundary line passing through the boundary so that a ratio of light (L1) diverged and guided toward the second light guide part is greater than a ratio of light (L2) diverged and guided toward the third light guide part.
