照）。 Reference numeral 21 denotes a contact piece (corresponding to the "portion that contacts the cylindrical body" of the present invention), which is fitted into the fitting section 23 of the protruding molded part 19 and constitutes a part of the protruding molded part 19. are doing. This contact piece 21 corresponds to a contact portion corresponding to the cylindrical body 13 in this invention,
Its shape is approximately elliptical. Also, this contact top 2
The material of No. 1 is a brass material (obtained by heat treating brass) having a Rockwell B hardness of 40 to 60. The reason for limiting the hardness of the material of the contact piece 21 is Rockwell B.
If the hardness exceeds 60, the forming surface of the aluminum cylindrical body 13 may seize with the forming spatula 15, and as a result, the roughness of the forming surface may deteriorate. If it is less than 40, it will be too soft and will wear easily (see Figure 4).

The rotational molding apparatus for cylindrical bodies according to the present invention rotates an aluminum cylindrical body or a forming spatula, and forms an end portion of the cylindrical body with the forming spatula. The cylindrical body made of aluminum has a Rockwell B hardness of 110 to 241, and at least the portion of the forming spatula that contacts the cylindrical body is made of a brass material with a Rockwell B hardness of 40 to 60. Even when the body is molded, as shown in FIG. 4, the molding surface of the cylindrical body does not seize with the molding spatula, and as a result, the molding surface can maintain its smoothness. In addition, when considering the relationship with the hardness of the aluminum cylinder,
If the Rockwell B hardness is softer than the range of 40 to 60, it is impossible to form an aluminum cylindrical body, and if it is hard, seizure will occur.
