Claim:
A vehicle headlamp comprising: a bulb comprising a flange and a terminal; a terminal fitting to which the terminal of the bulb is coupled; a lamp unit comprising a bulb attaching portion into which the bulb is inserted and attached from behind; an outer housing configured to engage with the lamp unit at a location behind the bulb attaching portion; an inner housing disposed inside the outer housing such that a clearance is provided in a radial direction between the outer housing and the inner housing and such that, relative to the outer housing, the inner housing is movable in an axial direction and is rotatable about an axis extending in the axial direction; and a spring disposed between the outer housing and the inner housing to bias the inner housing toward the bulb in the axial direction; wherein the outer housing comprises a first restricting portion, wherein the inner housing comprises: a terminal housing portion configured to accommodate the terminal fitting; a bulb pressing portion configured to contact a bottom portion of the bulb; and a second restricting portion, wherein, when the outer housing is engaged with the lamp unit, the spring biases the inner housing such that the bulb pressing portion presses the bulb to press the flange of the bulb against the bulb attaching portion of the lamp unit and such that the first restricting portion is separated from the second restricting portion, and wherein, when the outer housing is disengaged from the lamp unit, the spring biases the inner housing such that the inner housing is displaced toward the bulb in the axial direction and such that the first restricting portion and the second restricting portion are engaged with each other to restrict a further displacement of the inner housing.
