FIG. 3 shows an enlarged part of FIG. The vehicle lamp 100 shown in FIGS. 2 and 3 includes a fixed unit 10 arranged on the vehicle body 2 side, which is a fixed portion, and a movable unit 20 arranged on the back door 7 side, which is a movable portion. The fixed side unit 10 and the movable side unit 20 are separated with a gap 30 therebetween. The vehicle lamp 100 has a so-called slant shape, which is curved or bent toward the rear side from the vehicle inner side to the vehicle outer side.

The fixed unit 10 includes a light source (first light source) 11, a light guide 12, an inner housing 13, an inner lens 14, an outer lens (first outer lens) 15, a lamp housing 16, and a reflecting member 19. and

The light source 11 is, for example, a semiconductor type light source such as an LED. The light source 11 supplies light to the fixed unit 10 .

The light guide 12 guides the light from the light source 11 and emits it upward. FIG. 4 is a diagram schematically showing an example of the optical member (first optical member) 8. As shown in FIG. As shown in FIGS. 2 to 4, the light guide 12 is rod-shaped, and is arranged in a curved state toward the rear side from the inside to the outside of the vehicle. The light guide 12 has an incident surface 12a at the end on the back door 7 side (movable side, left side). The incident surface 12a is planar, for example. The light guide 12 has an end surface 12b on the side opposite to the incident surface 12a, that is, at the end on the gap 30 side. As shown in FIG. 4, the light guide 12 internally reflects the light L1 incident from the entrance surface 12a by the prism portion 12c arranged on the lower side surface and emits it from the output portion 12d on the upper side surface. , the light is guided to the inner lens 14 .

The inner lens 14 has a rod-shaped portion 14r and a plate-shaped portion 14s. The rod-shaped portions 14r are arranged above the light guide 12, and arranged side by side along the direction in which the light guide 12 extends. The bar-shaped portion 14r extends linearly, for example, along the vertical direction. The rod-shaped portion 14r has an incident surface 14a and an exit surface 14b. The incident surface 14 a faces the upper side surface of the light guide 12 . The rod-shaped portion 14r is arranged so that the incident surface 14a faces the light guide 12 with a gap therebetween. The incident surface 14a allows the light emitted from the upper side surface of the light guide 12 to enter inside.

The exit surface 14b emits the light incident inside. A prism portion 14c is formed on the rear side of the emission surface 14b in the vehicle-mounted state. The prism portion 14c reflects the light incident from the entrance surface 14a and internally reflected by the exit surface 14b to the front side when mounted on the vehicle. The light reflected by the prism portion 14c is emitted in the front direction from the emission surface 14b of the rod-shaped portion 14r. In the present embodiment, the light reflected by the prism portion 14c is emitted rearward of the vehicle from the emission surface 14b, for example.

The plate-like portion 14s is formed integrally with the rod-like portion 14r. 14 s of plate-shaped parts connect between the adjacent rod-shaped parts 14r. The plate-like portion 14s is, for example, a plate-like shape and is arranged along the vertical direction so as to correspond to the rod-like portion 14r. The plate-like portion 14s has an incident surface 14d, a reflecting surface 14e, and an output surface 14f. The incident surface 14 d faces the upper side surface of the light guide 12 .

Next, an example of the operation of the vehicle lamp 100 configured as described above will be described. When the driver performs a predetermined operation such as operating a direction indicator on the vehicle side or operating a hazard switch, the vehicle lamp 100 switches the light source 11 of the fixed unit 10 and the movable unit 10 in response to the operation. Light is emitted from each of 20 light sources 21 .

FIG. 5 is a diagram schematically showing an example of a path of light when the vehicle lamp 100 is turned on. As shown in FIG. 5 , light emitted from the light source 11 of the fixed-side unit 10 enters the light guide 12 and is guided by the light guide 12 . A portion of the guided light L1 is guided from the light guide 12 to the inner lens 14 and emitted from the emission surfaces 14b and 14f of the inner lens 14 to the front side. The light L1 is emitted forward from the front portion 17 of the outer lens 15 .

Further, part of the guided light L2 is emitted from the end surface 12b of the light guide 12 toward the leg portion 18 side.

As shown in FIGS. 9 to 11, in the inner lens 114, each of the bar-shaped portion 114r and the plate-shaped portion 114s is formed with a strip-shaped prism portion 114x along the vertical direction on the front side. The prism portion 114p is provided over the entire direction in which the inner lens 114 extends.

In the folded portion 114t, a strip-shaped prism portion 114y extending in the vertical direction is formed on the first surface 114m on the vehicle inner side, and a strip-shaped prism portion 114z extending in the vertical direction is formed on the second surface 114n on the vehicle outer side. be done. The prism portion 114y diffuses the light traveling through the folded portion 114t. The prism portion 114z emits the light diffused by the prism portion 114y toward the outside of the vehicle. The prism portion 114y has a larger pitch than the prism portion 114z. In other words, the prism portion 114z is formed finer than the prism portion 114y.

FIG. 12 is a diagram showing a state in which the outer lens 115 is viewed from inside. As shown in FIG. 12, the outer lens 115 has a prism portion 118 a formed on the inner surface side of the leg portion 118 . The prism portion 118a has a strip shape along the vertical direction. The prism portion 118a internally reflects the light incident on the outer lens 115 from the outside of the gap (the gap 30) to the outside (the gap 30).

In the configuration shown in FIGS. 7 to 12 , the reflecting member 119 reflects the light emitted from the inner surface of the folded portion 114 t of the inner lens 114 toward the outer side of the vehicle. The light reflected by the reflecting member 119 is incident on the folded portion 114t and emitted from, for example, the prism portion 114z. In this way, with the configuration in which the inner lens 114 is provided with the folded portion 114t, light can be efficiently emitted to the outside of the vehicle.
