摘要

[Problem]To provide a structure that achieves a reduction in size for a rotary forge device equipped with a spherical seat having a shaft that swings and rotates together with a mold.[Solution]The other end portion in the axial direction of a swinging shaft 13 is supported in a state in which movement toward one side (the lower side) in the axial direction with respect to a drive mechanism 17 is prevented, and a member for preventing the swinging shaft 13 from moving toward one side in the axial direction with respect to a frame 10 is not included at a portion of the swinging shaft 13 positioned between a convex spherical seat 14 and the drive mechanism 17 in the axial direction.
