A first screw 81 having a first manipulation portion 81a and a second screw 91 having a second manipulation portion 91a extend through the heat sink 11. A reference position of an optical axis Ax is adjusted in a first direction by manipulating the first manipulation portion 81a. The reference position of the optical axis Ax is adjusted in a second direction intersecting the first direction by manipulating the second manipulation portion 91a. Of the heat sink 11, at least a portion in which the first manipulation portion 81a and the second manipulation portion 91a are disposed, is disposed outside the housing 2. ## Claims ### Claim 1 A lighting apparatus for mount in a vehicle, the lighting apparatus comprising: a housing that defines and forms at least a part of a lamp chamber; and a lamp unit disposed in the lamp chamber, wherein the lamp unit includes a light source, a heat sink to which the light source is fixed, a projection lens through which at least a part of light emitted from the light source passes, a first screw that extends through the heat sink and has a first manipulation portion, and a second screw that extends through the heat sink and has a second manipulation portion, a reference position of an optical axis of the projection lens is adjusted in a first direction by manipulating the first manipulation portion, and the reference position of the optical axis is adjusted in a second direction intersecting the first direction by manipulating the second manipulation portion, and at least a portion of the heat sink, in which the first manipulation portion and the second manipulation portion are disposed, is disposed outside the housing. ### Claim 2 (depends on 1) The lighting apparatus according to claim 1, wherein a plurality of grooves extending in a direction corresponding to a vertical direction of the vehicle are formed in a region including a position in the heat sink opposite to the light source, and the first screw and the second screw pass through the heat sink at positions that avoid the region. ### Claim 3 (depends on 1) The lighting apparatus according to claim 1, wherein the lamp unit includes a holder that holds the projection lens, and the holder includes a first portion that is displaceable in the first direction by the first screw, and a second portion that is displaceable in the second direction by the second screw, independently of the first portion. ### Claim 4 (depends on 3) The lighting apparatus according to claim 3, wherein one of the first portion and the second portion is displaceable so as to parallel-move the optical axis in corresponding one of the first direction and the second direction. ### Claim 5 (depends on 4) The lighting apparatus according to claim 4, wherein the other of the first portion and the second portion is displaceable so as to tilt the optical axis in the other of the first direction and the second direction. ### Claim 6 (depends on 3) The lighting apparatus according to claim 3, wherein one of the first portion and the second portion is displaceable so as to tilt the optical axis in corresponding one of the first direction and the second direction. ### Claim 7 (depends on 1) The lighting apparatus according to claim 1, further comprising: an actuator including a drive shaft that displaces the optical axis in the first direction, wherein the first screw and the drive shaft are disposed side by side along a direction in which the first screw and the drive shaft extend. ### Claim 8 (depends on 7) The lighting apparatus according to claim 7, wherein the first direction is a direction corresponding to a vertical direction of the vehicle. ### Claim 9 (depends on 1) The lighting apparatus according to claim 1, wherein the lamp unit includes a movable shade that changes a shape of a light distribution pattern formed by the light emitted from the light source. ### Claim 10 (depends on 1) The lighting apparatus according to claim 1, wherein a sealing member is clamped between a portion of an outer surface of the housing and a portion of the heat sink that is disposed outside the housing. ### Claim 11 (depends on 10) The lighting apparatus according to claim 10, wherein a groove that receives the sealing member is formed one of the portion of the outer surface and the portion of the heat sink, and a protrusion that presses the sealing member is formed in the other of the portion of the outer surface and the portion of the heat sink is formed.
