A method of molding a boot for a constant velocity joint includes: molding a compact by injection molding; raising split dies of an inner die so as to separate the split dies from a set ring; raising a core shaft of the inner die so as to separate the core shaft from the split dies; separating each of the split dies from the compact; introducing a lower end portion of the separated split die into the set ring along an engaging surface; and inserting a lower end portion of the core shaft through the set ring from above the set ring, and pressing upper end portions of the split dies downward by a protruding portion at an upper end portion of the core shaft so that the lower end portions of the split dies are engaged with the engaging surface and the split dies are brought into close contact. |
