NOVELTY - A holding lever pin is attached to elevatable hollow shaft and holding lever holds diameter expansion part of single crystal. Crystal holding mechanism transfers lever drive units from standby to holding position, before transferring holding lever to holding position. Support plate over elevatable carriage base is attached to pulling up mechanism of hollow shaft and crystal holding mechanism.    USE - For manufacture of silicon single crystal.    ADVANTAGE - The apparatus enables pulling up single crystals of large weights without any inclination.    DETAILED DESCRIPTION - A single crystal manufacturing apparatus comprises a rotatable and elevatable hollow shaft (8), a holding lever pin (22) attached to the hollow shaft, and holding lever(s) (9) which holds the lower part of diameter expansion part (24a) of single crystal (24) at a predetermined position. A crystal holding mechanism has holding lever drive units that transfers holding lever from a standby position to a holding position. A suspended seed chuck attaches to lower end of seed crystal, and is arranged by axial center of hollow shaft. On elevation of the hollow shaft winding is carried out independently. The hollow shaft has a pulling up mechanism that rotates synchronously with a main wire (10). A support plate (3) is attached to the pulling up mechanism and crystal holding mechanism. An elevatable carriage base (14) mounts the support plate and an elevation unit elevates the carriage base.    An INDEPENDENT CLAIM is also included for single crystal manufacture, involving Czochralski method. Transition of crystal seed is removed using a dash neck method and single crystal is formed. Diameter of the crystal is then enlarged to form diameter expansion part (24a), and further reduced to predetermined diameter to form fixed diameter part (24b) having predetermined length. When height of fixed diameter part is equivalent to holding lever, the holding lever is transferred from holding position to standby position.
