Abstract
Abstract A retractable lamp which includes a lamp pivotally held at a first axis to be extended out of and retracted into a housing, a lampcover pivotally held at a second axis to open and close an opening of the housing for exposing and retracting the lamp, and a swing member for imparting motions to the lamp and the lampcover. The retractable lamp can reduce the open area between the lampcover and the lamp which are exposed out of the housing. Due to the reduction of the open area, a reduction in air resistance and noise is thus created and an improvement in the fuel efficiency of an automobile can be realized.
