A vehicle headlamp having a leveling device for adjusting an optical axis, said vehicle headlamp comprising: a fixing member; a tilting member which is tiltably mounted on the fixing member; and the leveling device, wherein: the fixing member has: a mount portion in which a through hole is provided, wherein: the leveling device has: a housing for providing a cylinder portion which is inserted into the through hole and is mounted at a rim of the through hole; a drive unit which is disposed in the housing; and a shaft which is retractably mounted on the housing and cylinder portion, is mounted on the tilting member, is advanced/retracted with respect to the housing and the cylinder portion by driving the drive unit, for tilting the tilting member with respect to the fixing member to adjust an optical axis of the vehicle headlamp; the fixing member further has an abutment protrusive portion which is provided on the mount portion; the leveling device further has an abutment face protrusive portion which comes in abutment against the abutment protrusive portion of the fixing member characterized in that a rib is integrally provided inside the housing of the leveling device; the abutment face protrusive portion of the leveling device is provided partly of the housing to prevent occurrence of a surface sink with an exterior face of the housing corresponding to the rib; and that the abutment face protrusive portion is provided partly of the housing, thus allowing the thickness of the housing to be increased at sites of the abutment face protrusive portion and decreased at other sites with respect to the abutment face protrusive portion. a fixing member; a tilting member which is tiltably mounted on the fixing member; and the leveling device, wherein: the fixing member has: a mount portion in which a through hole is provided, wherein: the leveling device has: a housing for providing a cylinder portion which is inserted into the through hole and is mounted at a rim of the through hole; a drive unit which is disposed in the housing; and a shaft which is retractably mounted on the housing and cylinder portion, is mounted on the tilting member, is advanced/retracted with respect to the housing and the cylinder portion by driving the drive unit, for tilting the tilting member with respect to the fixing member to adjust an optical axis of the vehicle headlamp;
