Claim Text:
1. A rubber vulcanizer comprising: a pair of heat plates disposed to be opposed to each other in a prescribed direction and to be separated from each other in the prescribed direction; one or more dies for rubber molding stacked on each other in the prescribed direction between the heat plates to be pressurized by the opposed heat plates, wherein the rubber vulcanizer is able to realize either a state in which the dies of which the number is N are stacked on each other in the prescribed direction between the heat plates, or a state in which the dies of which the number is (N+1) are stacked on each other in the prescribed direction between the heat plates, where N is a natural number that satisfies at least a condition that 1≦N≦M, and M is a certain positive integer; and a partially-pressurizing device that is able to selectively pressurize, in the prescribed direction and independent of the pressurization by the opposed heat plates, a number of the dies that are stacked on each other in the prescribed direction, which number is smaller than a maximum number of the dies that are stacked on each other in the prescribed direction during rubber vulcanization.
