Abstract: PURPOSE: To provide a device for engaging holding parts with spectacle lenses, where the spectacle lenses are prevented from falling and being broken owing to the interference of an arm with the holding parts. CONSTITUTION: The device which is arranged in a plate so as to fix the holding parts to the spectacle lenses is provided with one arm 13 receiving the holding parts so as to be rotation possible and a carriage for permitting the arm 13 to rotate between a lifting load end position and lowering engagement end position. The carriage can straightly move between a drawing halt position and the advance end of a movement position. In a transmitting device which is operated between a driving device and one of the arm 13 or the carriage, the arm 13 is located at a drawing engagement position when the carriage is located at least at the position being adjacent to the advance end of the movement position. A restraining device is operated between the arm 13 and the carriage and permits the arm 13 to be restrained to the carriage at a lowering halt position in terms of a liberation.
