Abstract: In one embodiment of this invention, a blow nozzle, which introduces blow air into a molded article in which a flange portion is supported by a blow cavity mold, includes a nozzle main body and an outer nozzle. The outer nozzle includes a first surface brought into press contact with the flange portion and a second surface disposed further outwards in a radial direction than the first surface and being brought into contact with the blow cavity mold. From when the nozzle main body is moved and the first surface is brought into contact with the flange portion to when the second surface is brought into contact with the blow cavity mold and the movement of the nozzle main body is stopped, the first surface of the outer nozzle is overdriven so that the flange portion is airtightly sealed by the first surface.

Abstract: A mold includes a position adjustment mechanism that receives a shaft portion extending from a cavity mold, which accommodates a preform, and adjusts a position where the cavity mold is held on a plane intersecting an extending direction of the shaft portion. The position adjustment mechanism includes a first member in which a linear cam hole that receives the shaft portion is formed, and a second member that is disposed to overlap the first member in the extending direction of the shaft portion and rotates with respect to the first member along a plane. The second member has an elongated hole that intersects the cam hole in a direction of the plane and positions the shaft portion together with the cam hole. Further, a position where the cam hole and the elongated hole intersect each other moves along a longitudinal direction of the cam hole by rotation of the second member.
