PROBLEM TO BE SOLVED: To provide a mechanism for pulling out a cast body, that facilitates exchange of consumables such as clamping members for holding a cast body and that reduces the component cost of the clamping members. SOLUTION: The clamping mechanism 64 is equipped with a mandrel 100, swinging parts 102, and lug members 104. The mandrel 100 is connected to the end of a driving rod 86 in the direction of the arrow A2. At both ends of the mandrel 100, the first and second tapered parts 106 and 108 are each formed. The swinging parts 102 are rotatably mounted pivotally on the rotary shaft 110 formed on the housing 105. A part of the swinging parts 102 is exposed outside the housing 105 through the opening 112 formed therein. The lug members 104 abutted on the inner periphery 62 of a cylindrical cast body 60 are each structured as a separate body from the swinging parts 102 and mounted thereon at a part exposed outside the housing 105 freely attachably/detachably with a bolt 124 or the like.
