It is inserted into a substantially U-shaped lens attachment portion 33 that is integrally provided with the lens, and is fixed with an adhesive 34. In this case, not only the adhesive 34 but also ultrasonic welding may be used. Further, the rear end portion of the clearance lens 6 is fixed to the vehicle body 2 together with the lamp body 4 by a tapping screw 35, as shown in FIG. The entire clearance lens 6 is colorless, and a diffuser lens 11 is formed on the entire surface of the inner surface, and the rear end of the surface of the side lens portion 6b has a substantially V-shape to provide diagonal forward illumination. A tar/signal display lens 10 integrally having a portion 10A and an oblique rear illumination portion 10B is integrally formed to protrude corresponding to the light chamber 7B, and furthermore, this display lens 10
An inner lens 36 (see FIGS. 1 and 2) is disposed inside the lens.

る。In the lamp 1 having such a configuration, when the clearance bulb 8 is turned on at night, etc., the front lens part 6a and the side lens part 6 of the clearance lens 6 are turned on.
The front half of b is illuminated, thereby displaying the vehicle width for the front and sides of the vehicle. On the other hand, when turning on the turn signal bulb 9 when turning right, the light is colored cyan when it passes through the inner lens 36 and illuminates the turn signal display lens 10 of the clearance lens 6 to indicate a right turn. In this case, the turn signal display lens 10 has a V-shaped cross-sectional shape in plan view and is formed to protrude from the side lens portion 6b of the clear second lens 6, so that it can be used not only on the side of the vehicle body but also in front of the vehicle body, diagonally. It is also visible from the front and diagonally behind. Moreover, the light that comes out of the turn signal bulb 9 and passes through the diagonally front lens surface 36A of the inner lens 36 is diffused forward and sideways at a wide angle by the diffusion prism 3γ, and the light that passes through the diagonally rear lens surface 36B is Since the light is refracted at a large angle toward the rear of the vehicle body by the refracting prism 38, the confirmation angle of the turn signal display lens 10 is wide, making confirmation particularly easy and reliable from the direction 806 behind the vehicle body.

せ九車輌用灯具を提供し得る。As explained above, the vehicle lamp according to the present invention has a geometrically shaped turn signal display lens protrudingly formed on the surface of the side lens part of the clearance lens, and an inner lens of the same shape inside the turn signal lens. A turn signal bulb is disposed, a diffusion prism for diffusing the light from the turn signal bulb is disposed on the oblique front lens surface of the inner lens, and a refraction prism is provided on the diagonal rear lens surface for refracting the light from the turn signal bulb toward the rear of the vehicle body. Since the prism is provided, the visibility angle of the turn signal lens is wide, making it easy to see not only the sides and front of the vehicle but also the rear of the vehicle, improving safety and improving the visibility of nine vehicle lights. can be provided.
