Abstract

The lens holder10 related to the embodiment of this invention can be fixed removably on the front part(21) of the light guide(20), and used for collecting light which emits from the front part(21) of the light guide(20). The lens holder comprised : a cylindrical part(11) with a ring-shaped convex part(11a) located on inner surface, and the ring-shaped convex part(11a) is disposed on the opposite side of the ring-shaped slot part(21b) being formed on the front part(21) of the light guide(20); lens(12) is settled on the front part of the cylindrical part(11); a ring element(13), which is accommodated in the slot part(21b) of the light guide(20) side and the convex part(11a) of the cylindrical part(11), and can deform elastically in the direction of diameter.
