In a built-in ashtray, when the cigarette lighter is fitted into a swiveled-up holder, without any special locking mechanism for the holder, an automatic sliding of the ashtray into its closed position is avoided. A spring has a progressive characteristic spring curve such that the spring force, which acts upon the ashtray in its moved-out operative position and presses the ashtray toward the outside, is greater than the oppositely directed force component of the operating force acting in the plane of the spring force during the inserting or operating of the cigarette lighter.
