    Abstract: The resin molding apparatus (200) is capable of rotatably support, around an axis of a neck portion (2), a hollow molded product having a main body having a form of a container and the cylindrical neck portion (2). A pinched portion (4), which is pinched by neck portion pinching parts (13, 14) of metallic mold members (11, 12) of the apparatus (200), is formed around the neck portion (2). An outer profile of the pinched portion (4) around the axis of the neck portion (2) is a non-circular profile. An integrated inner profile of the mated neck portion pinching parts (13, 14) is a profile along an outer profile of the pinched portion (4). When the neck portion pinching parts (13, 14) pinch the pinched portion (4), the neck portion pinching parts (13, 14) push the pinched portion (4) to rotate the hollow molded product, thereby correcting the rotation angle around the axis.
