As shown in FIG. 6, the outer lens 3 is mounted on the front opening side of the housing 1 so as to cover the valve LP. The outer lens 3 is, for example, a colored transparent or transparent clear lens.

As shown in FIG. 6, the inner lens 5 serves to guide the light Hv from the bulb LP to the rear of the vehicle body, and has a cross section having a prism 39 on the surface opposite to the bulb LP. It is formed as a substantially L-shaped lens. The inner lens 5 has an inner lens attachment recess 3 formed between the front reflection portion 7 and the dark portion 9.
7 and fitted.

The inner lens mounting recess 37 is shown in FIG.
As shown in FIG. 3, a part of the boundary 41 between the front reflection part 7 and the dark part 9 is cut out. The inner lens mounting concave portion 37 is formed at the boundary between the front reflecting portion 7 and the dark portion 9 as a concave substantially corresponding to the shape of the mounting fixing portion of the inner lens 5. The bottom surface 37 of the inner lens mounting recess 37
“a” is lower than the position where the boundary line 41 is formed, and lower than the position of a ridge line 51 a due to a notch described later.

The inner lens mounting recess 37
On the bottom surface 37a of the base member, a projection 43 for positioning the inner lens 5 and a boss hole 45 for screwing the inner lens 5 are formed. As shown in FIG. 7, a screw 47 for fixing the inner lens 5 to the inner lens mounting recess 37 is screwed into the boss hole 45. In order to secure the mounting of the inner lens 5 with the screw 47, a boss 49 having a boss hole 45 is protruded to the side opposite to the inner lens mounting recess 37 so as to extend the length of the screw portion. We have secured enough.

A part of the boundary 41 cut out (hereinafter referred to as a notch 51) has a mountain-shaped R-shape whose central portion protrudes upward, as shown in FIGS. ,
In addition, both ends 51b and 51c of the ridge 51a of the notch 51 protrude forward from the center position of the ridge 51a, and are connected to the dark portion 9. Therefore, the ridge 51a of the notch 51 looks like a curve that is continuous with the boundary 41 when the housing 1 is viewed obliquely from above, as shown in FIG.

As described above, in the notch portion 51, the ridge line 51 is formed so as to be a curve continuous with the boundary line 41.
Since a is formed, the appearance is good. If the notch 51 is not provided with an R-shape, the ridgeline 51a does not look like a curve continuing to the boundary line 41, and the appearance is poor.

In the signal lamp configured as described above, the light Hv from the bulb LP passes through the front reflection section 7.
Is emitted to the front of the vehicle body via the outer lens 3 by the reflecting mirror. Also, some light Hv from this bulb LP
As shown in FIG. 6, the light is guided to the dark portion 9 by the inner lens 5, irradiated to the prism 53 formed on the outer lens 3, and irradiated toward the rear of the vehicle body via the outer lens 3. .

Light Hv guided by the inner lens 5
Is formed by cutting out a part of the boundary line 41 between the front reflecting portion 7 and the dark portion 9 to form the inner lens mounting concave portion 37, so that there is no portion that blocks the light Hv. The light is guided to the prism 53. In this way, even if the angle θ described with reference to FIG. 8 is an acute angle, the light Hv of the bulb LP can be guided to the dark part 9.

Also, since the inner lens 5 is fitted and mounted in the inner lens mounting recess 37, the rigidity of the mounting portion of the inner lens 5 is increased, and the mounting of the inner lens 5 is facilitated. it can.

Also, since the bottom surface 37a of the inner lens mounting concave portion 37 is lower than the ridge line 51a of the notch portion 51, when the signal lamp is viewed from the side of the vehicle body, the notch portion 51 becomes a shadow and the inner lens Screw 4 for attaching 5
7 disappears, and the appearance is improved. In particular, when the outer lens 3 is transparent, the inside of the outer lens 3 can be visually observed, so that the present invention has industrial value.

Although a specific embodiment to which the present invention is applied has been described above, the present invention can be variously modified without being limited to the above-described embodiment.

For example, if a lateral prism is formed on the outer lens 3, the light Hv from the bulb LP is diffused to further improve the appearance.

[0031]

The present invention is embodied in the form described above and has the following effects.

According to the signal light of the present invention, since the inner lens is fitted and attached to the concave portion formed by cutting out a part of the boundary line between the front reflecting portion and the dark portion, the inner lens is connected to the bulb by the inner lens. Light can be guided backward. In addition, since the inner lens is fitted in the concave portion, the rigidity of the mounting portion of the inner lens can be increased, and the inner lens can be easily mounted.

Further, according to the signal light of the present invention, since the bottom surface of the concave portion in which the inner lens is fitted is lower than the ridge line of the notch portion, the notch portion is formed when the signal light is viewed from the side of the vehicle body. The screw that attaches the inner lens becomes invisible as a shadow, making the appearance better.
