PROBLEM TO BE SOLVED: To solve a problem that specified light distribution characteristics cannot be obtained due to shielding by a headlight since an outer lens of a recent front combination lamp is formed into a shape along a vehicle body and a lamp fitting mounted to the outside of the vehicle body such as a turn signal lamp, and retreats. SOLUTION: A plurality of inner face prisms provided at a prescribed position of the inner face of the outer lens includes: a first surface for making light from a lamp of lamp fitting incident to a lens on the inner face side of an outer lens and returning it to the inner face side by totally being reflected on the outer face side; and a second surface for taking the light returned to the outer face side of the outer lens by the first surface via the outer lens into air at a predetermined angle. The light taken from the inner face prism into the outer lens is transmitted through the outer lens at a predetermined angle and emitted to the outside of the outer lens.
