PROBLEM TO BE SOLVED: To prevent a stress from being generated near a filler metal after the curing of a cast material. SOLUTION: This casting mold consists of a top force 1 and a bottom force 2 which are tightly clamped together and a filler metal 24 of a cylindrical shape through which a cylindrical collar 5 is made to penetrate, in cavity 3 formed between both forces 1, 2 and a barlike support pin 6 arranged running through inside the collar 5 via an appropriate space. The support pin 6 has O-rings 7, 7 wound around the former and the O-rings 7, 7 are in contact with the collar 5 and the support pin 6. In the curing process of a liquid cast material packed in the cavity 3, the O-rings 7, 7 are deformed by a force generated by contraction of the cast material and the position of the filler metal 24 is changed within the range of the space to prevent a stress from being generated near the filler metal 24.
