## Abstract

The present disclosure provides a vehicle lamp including: a main bracket pivotably supported to a lamp body; and a sub-bracket pivotably supported to the main bracket. A first optical unit is supported directly to the main bracket, and three second optical units are supported to the main bracket via the sub-bracket. An optical axis adjustment for the first optical unit and the three second optical units is collectively performed by pivoting of the main bracket, and an optical axis deviation between the first optical unit and the three second optical units is corrected by pivoting of the sub-bracket.

## Claims

### Claim 1

A vehicle lamp comprising:
a main bracket pivotably supported by a lamp body;
a plurality of optical units supported by the main bracket and emitting light to form a predetermined light distribution pattern, the plurality of optical units including a first optical unit and a plurality of second optical units; and
a sub-bracket supported to be pivotable vertically with respect to the main bracket about a horizontally extending pivoting axis,
wherein
the first optical unit is supported directly by the main bracket, and the plurality of second optical units are fixed to the sub-bracket and supported by the main bracket via the sub-bracket.

### Claim 2 (depends on 1)

The vehicle lamp of claim 1, wherein the plurality of second optical units are arranged such that at least one of the second optical units irradiates light in a direction different from that of the other second optical units in a horizontal direction.

### Claim 3 (depends on 2)

The vehicle lamp of claim 2, wherein
a projection lens is disposed in front of each of the second optical units in a state of being supported by the main bracket, to cause light emitted from the corresponding second optical unit to be incident on the projection lens, and
the sub-bracket is pivoted with respect to the main bracket about a pivoting axis which extends in a direction perpendicular to a direction positioned in the middle of a plurality of light irradiation directions from the plurality of second optical units.

### Claim 4 (depends on 1)

The vehicle lamp of claim 1, wherein the light emitted from the first optical unit forms a central zone of the predetermined light distribution pattern.

### Claim 5 (depends on 2)

The vehicle lamp of claim 2, wherein the light emitted from the first optical unit forms a central zone of the predetermined light distribution pattern.

### Claim 6 (depends on 3)

The vehicle lamp of claim 3, wherein the light emitted from the first optical unit forms a central zone of the predetermined light distribution pattern.

### Claim 7 (depends on 4)

The vehicle lamp of claim 4, wherein a low beam light distribution pattern is formed as the predetermined light distribution pattern.

### Claim 8 (depends on 5)

The vehicle lamp of claim 5, wherein a low beam light distribution pattern is formed as the predetermined light distribution pattern.

### Claim 9 (depends on 6)

The vehicle lamp of claim 6, wherein a low beam light distribution pattern is formed as the predetermined light distribution pattern.

### Claim 10 (depends on 1)

The vehicle lamp of claim 1, wherein the plurality of second optical units are arranged to be displaced rearwardly with respect to the first optical unit.

### Claim 11 (depends on 1)

The vehicle lamp of claim 1, wherein the main bracket is supported to be vertically and horizontally pivotable with respect to the lamp body, by a pivot disposed at a right upper side of the lamp body and two aiming screws disposed at a left side and a right lower side of the lamp body, respectively.

### Claim 12 (depends on 1)

The vehicle lamp of claim 1, wherein the first optical unit and the plurality of second optical units are arranged horizontally to each other.
