Claims (15)

1. A vehicle lamp body device provided with a turn light, a position light and a driving light inside a same headlight unit, wherein

a front and back direction, a vertical direction, and a width direction correspond to a front and back direction of a vehicle, a vertical direction of the vehicle, and a width direction of the vehicle when the device is in use and mounted on the vehicle, wherein

the device comprising:

a first lens for which a first light source for the turn light and a second light source for the position light and the driving light are alternately arranged; and

a second lens which is arranged below the first lens and on which light from the first light source and the second light source is made incident,

wherein

the first lens includes a first body part having a predetermined length in the width direction,

the first light source and the second light source are attached to a plurality of light source holding parts formed along the width direction at a rear end edge of the first body part in the front and back direction so as to emit light downward,

the second lens includes a second body part positioned below the first body part and having a predetermined length in the width direction,

at a rear end edge of the second body part in the front and back direction, light incident parts on which the light radiated from the first light source and the second light source is made incident are formed at positions corresponding to the light source holding parts of the first body part,

a first diffusion part is provided on a front end surface of the first lens, which is a light exit surface of the light of the first lens and a second diffusion part is provided on a front end surface of the second lens, which is a light exit surface of the light of the second lens.

2. The vehicle lamp body device according to claim 1 , wherein the second lens comprises a groove part which reflects and disperses the light from the first light source or the light from the second light source to an area of a light source which is not lighted.

3. The vehicle lamp body device according to claim 1 , wherein the first diffusion part and the second diffusion part are configured such that light distribution components are different.
