Abstract
An electric heater is placed so as to cover an upper opening of a crucible. Then, a plurality of angle members are disposed along the side portions of the electric heater and are pressed and fixed by clamps. The clamp includes, at its bottom, a curved portion formed by bending a plate-like spring member into a convex shape, and generates pressing force between the curved portion and corresponding claw portions at the upper edge, thereby clamping the crucible.
