Beschreibung
Zusammenfassung:	A vehicle lamp is provided which includes a toroidal lens 30 which extends into an arc shape so as to surround a light source 20 from a front side thereof. By adopting this configuration, light emitted from the light source 20 is allowed to emanate from the toroidal lens 30 as it is as diffuse light in a horizontal plane in which the toroidal lens 30 extends, while the light is allowed to emanate from the toroidal lens 30 as parallel light in a vertical plane. Furthermore, a front surface 30Aa of a central portion 30A of the toroidal lens 30 in the direction in which the toroidal lens 30 extends into the arc shape is formed so as to be displaced rearwards relative to an imaginary extensional plane C1 from front surfaces 30Ba of general portions 30B which are situated at both sides of the central portion 30A.
