A retractable handle assembly for luggage in a pulling operation, press a push button to cause a spring in a plunger of buffer device to gradually and damply extending upward immediately. As a result, both a piston rod and thus the buffer device move upward gradually and damply. Also, a sliding tube coupled to the locking mechanism moves upward gradually and damply. As an end, the handle assembly is capable of gradually and damply extending from a top of the luggage a predetermined distance. At this position, a user can easily pull the handle assembly up to its maximum.
