PURPOSE:To prevent a damage caused by a molten metal, of an elastic mechanism by attaching the elastic mechanism to a base housing. CONSTITUTION:As for a clamping mechanism 1, a spring case 27 is attached to a base housing 9 so that an operating end part 32 of the spring case 27 being an elastic mechanism is displaced elastically in the direction B against an outer frame 28. Also, the operating end part 32 is connected to a flange part 23 of a cover housing 22 through an arm ring 48 and a fine adjustment supporting mechanism 62. Accordingly, the spring case 27 is provided on a part separated from holes 11, 16 and 64, with regard to the direction B, and it is not exposed to high heat. |
