PROBLEM TO BE SOLVED: To provide a metallic mold for centrifugal casting in which a ring- shaped frame body can easily be fitted/separated to/from a metallic mold body and which is therefore produced at a low cost and enables increase of casting cycle. SOLUTION: When the ring-shaped frame body 16 is fitted to the cylindrical metallic mold body 12, the ring-shaped frame body 16 is provided with a ball plunger 32 engaged with the recessed part 20 of the above metallic mold body 12. Balls 38 in the ball plunger 32 are engaged with the recessed part 20 of the metallic mold body 12 by shifting a chuck member 50 and holding the ring- shaped frame body 16 with the claw parts 52 of the member 50. The recessed part 20 is off-set against the balls 38 in the ball plunger 32 at the top part 42 by a distance (t). Thus, when the balls 38 are abutted on the one side surface of the recessed part 26, the ring-shaped frame body 16 is pushed to the surface 26 with the reaction of the abutment.
