2. Description of the Related Art A vehicular lamp such as a vehicular lamp has a lamp body having an open front, a lens covering the front opening of the lamp body, and a space defined by the lamp body and the lens, that is, a lamp. It is composed of a light source and the like arranged in the room.

Some of such vehicular lamps have a plurality of adjacent light chambers.

For example, a so-called rear combination lamp for an automobile has a structure in which a tail-and-stop lamp and a back lamp are integrally connected, and a light room corresponding to each of the plurality of types of lamps is usually provided. In general, a predetermined lens is separately attached to the reflecting portion of the integrally formed lamp body, and these plural kinds of lenses are generally integrally joined by integral molding or the like.

FIG. 3 shows an example of a conventional rear combination lamp for an automobile having such a structure (only the main part is shown in the drawing).

In FIG. 1, reference numerals b and c denote container-shaped lamp bodies which open forward, and these two lamp bodies b and c are located adjacent to each other in the left-right direction and are formed integrally with each other. At the same time, lens installation grooves d, d are formed along the periphery of the front opening. In the drawings, only the portions of the lens installation grooves d and d common to the lamp bodies b and c, that is, only the portions located where the front openings of the lamp bodies b and c are joined are shown.

[0007] The inner surfaces e and e 'of the lamp bodies b and c are reflectors having a substantially paraboloid of revolution.

F is a lens attached to the left lamp body b so as to cover the front opening thereof, and f 'is an outer lens attached to the right lamp body c so as to cover the front opening thereof. The lenses f, f 'are fixed to the lamp bodies b, c with the ridges g, g' projecting rearward from the respective outer peripheral edges, fitted inside the lens installation grooves d, d. The right side of the ridge g of the lens f is joined to the left side of the ridge g 'of the outer lens f'.

A lamp room h is defined by the left lamp body b and the lens f, and a light source i is disposed inside the lamp room h. A back lamp is formed by the lamp body b, the lens f and the light source i. j is configured.

In particular, a part of the light m which is incident on the portion near the right edge of the lens f among the direct light is internally reflected within the thickness of the lens f by the edge light effect and reaches the outer lens f '. rear,
The light m may be emitted forward from the outer lens f ′, and such light m is colored red when passing through the outer lens f ′, and thereby the tail and stop lamp l
A part of the light emitting surface may be brilliant.

Similarly, a part m 'of the light emitted from the light source i' of the tail and stop lamp 1 may be emitted from the lens f surface of the back lamp j.

Light m, m 'which causes such light leakage
Is a pseudo lighting, which is a serious problem for vehicular lamps.

Further, as described above, the tail and
Since the inner lens k of the stop lamp 1 is attached to the lamp body c by a screw or the like, there is a problem that the number of parts increases and the assembly takes time.

[0019]

In order to solve the above-mentioned problems, a vehicle lamp according to the present invention is arranged such that a reflex reflector having a shade attached to a rear surface thereof straddles the front surfaces of two adjacent lamp rooms. In addition, the end of the inner lens is sandwiched between the leading edge of the partition wall that defines the two lamp chambers and the back surface of the shade, and a light-shielding wall is provided on the shade so as to protrude rearward. The partition is arranged so as to overlap with the partition wall when viewed from the side.

[0020]

Therefore, according to the vehicle lighting device of the present invention, a portion straddling both of the front surfaces of the two adjacent lamp rooms is formed by the shade of the reflex reflector disposed here.
A non-light-emitting portion that does not emit light from a light source disposed in the lamp chamber to the front; and a light-shielding wall that protrudes rearward in the shade, and a partition that defines the light-shielding wall and two lamp chambers. Are arranged so as to overlap when viewed from the side, so that the light emitted from the light source does not pass through the adjacent lamp room or the lens thickness, and so-called pseudo lighting can be reliably prevented.

Further, since the end of the inner lens is sandwiched between the front edge of the partition and the rear surface of the shade, the mounting of the inner lens can be facilitated.
