Abstract
A lamp device for a vehicle is configured by a reflecting mirror, a lens in which lens steps for diffusing light are formed, and a light source positioned between the reflecting mirror and the lens. The reflecting mirror is divided into two portions by the vertical plane including the main optical axis of the reflecting mirror. A reflecting face is formed in the following manner. Reflected light from a portion which is positioned in one side with respect to the vertical plane propagates in a direction which is inclined with respect to the main optical axis and without intersecting the vertical plane including the main optical axis, and is then emitted through the lens steps formed in one portion of the lens. Reflected light from a portion which is positioned in the other side with respect to the vertical plane including the main optical axis propagates in a direction which is inclined with respect to the main optical axis and without intersecting the vertical plane including the main optical axis, and is then emitted through the lens steps formed in the other portion of the lens.
