Abstract: Apparatus for pulling a single crystal of this invention is suitable as a silicon single crystal pulling technology that meets the needs for increased efficiency in the manufacture of semiconductors and can thus be utilized in the field of manufacturing semiconductors. The apparatus includes pulling means for forming an engaging stepped portion on a single crystal and a holding mechanism for gripping the engaging stepped portion of the single crystal. As the weight of the single crystal increases as the single crystal pulling operation proceeds, the apparatus causes the holding mechanism to start holding the single crystal before the weight of the single crystal reaches the limit of a load that can be borne by the dash neck portion. As a result of such construction, even when pulling a single crystal that is heavy, the apparatus can engage and grip such single crystal reliably, thereby implementing safe production of single crystals free from falling accidents.
