That is, 1 has a cylindrical shape, is supported by a plurality of wheels 2 and is rotatable around a horizontal axis 3, and has end jigs 4 attached to both ends. Said cylinder type 1
While rotating the cylinder around the horizontal axis 3,
A resin liquid is injected into the cylindrical mold 1, and a resin pipe 5 is centrifugally formed on the inner peripheral surface of the cylindrical mold 1 between both end face jigs 4. In such a conventional centrifugal forming apparatus, the end face jig 4 is made of metal. Therefore, it is not easy to attach or remove the tube from the cylinder, and it must be firmly attached to prevent it from falling off during centrifugal molding.

状になることから脱落は完全に防止できる。 That is, the present invention has a cylindrical shape that is rotatable around a horizontal axis, and centrifugal molding is performed in which a resin tube is centrifugally formed on the inner peripheral surface of the cylindrical shape between end jigs attached to both ends of the cylindrical shape. In the apparatus, the end jig is made of rubber, and a hemispherical recess is formed at the end of the inner peripheral surface of the cylindrical shape, and a hemispherical convex part that can be fitted into the recess is formed on the outer periphery of the end jig. This paper proposes a centrifugal molding device that is integrally formed with the According to this configuration, by using the elastic force of the rubber to fit and remove the convex part into the concave part, it is possible to easily attach and detach the end face jig to and from the cylindrical shape with a single touch. During centrifugal molding, the centrifugal action causes the protrusions to sink into the recesses, so that falling off can be completely prevented.
以下、本考案の一実施例を第２図に基づいて説

されている。 Hereinafter, one embodiment of the present invention will be described based on FIG. 2. 10 is a cylindrical shape, and 11 is an end jig. Here, the end face jig 11 is made of rubber. A hemispherical recess 12 is formed in an annular shape at the end of the inner peripheral surface of the cylindrical shape 10. On the other hand, on the outer periphery of the end face jig 11, a hemispherical convex portion 13 that can be fitted into and removed from the recessed portion 12 is integrally formed in an annular shape.
