Abstract

PURPOSE: To simplify manufacture and to enable shortening of a manufacturing time, by a method wherein a reinforcing member is inserted through a base shaft, and a spherical shell, into which a tube material is formed on the outer circumference of the base shaft, is caulked for fastening.
CONSTITUTION: The reinforcing member 4 is inserted into a position where a spherical part 1a in a base shaft 2 is located, and the base shaft 2 is located in a cylindrical guide 5. The cylindrical tube material 7 is inserted through the outer circumference of the base shaft 2, and the tube material 7 is held by means of a retaining means 6. After the end part of the tube material 7 is carried with a pair of press molds 8 slided in the axial direction and in the proximity of each other, the retaining means 6 is moved again, and the press molds 8 are further slided in the proximity of each other. With this, a spherical shell 3 is formed along the shape of a cavity 8a in the press mold, and the periphery thereof is caulked on the outer circumference of the base shaft 2 for securing. Additionally, the reinforcing member 4 is secured on a projection part on an air inner surface of so caulked part. This simplifies manufacturing and permits shortening of a manufacturing time.
