ABSTRACT:
In a mold, at least a first half includes an insert member forming a cavity surface on one end side; a body member having an insertion part into which the insert member is inserted; and an insert member fixer interposed between the insert member and the insertion part, for holding the insert member. The insert member fixer is made of a shape memory alloy, and presses and holds the insert member when the insert member fixer restores its memorized shape, to make a center axis alignment of the insert member with respect to the body member.
