Abstract

PURPOSE: To facilitate bending of a seal part to circular truncated cone shape by a method wherein the seal part of fluororesin material which functions for sealing is shaved annularly having a double-ring appearance out of a cylindrical material, and a bending tool is pressed onto it while it is turned.
CONSTITUTION: In a sealing device comprising holding a seal member 1 of fluororesin material which consists of a circular truncated cone part 2 provided, for example, with a seal lip 3 and a spring groove 4 and a holding part 5 in slab form which is connected thereto with a holding member 10 consisting of an inner ring 11 and an outer ring 12, the seal member 1 is formed of an annular member 22 having a double-ring appearence shaved out of a cylindrical material 20. Then, it is fitted in a rotating means 27 coupled to the holding member 10 and provided with a driving means, a bending tool 30 in round bar form is pressed onto the annular member 22 as rotating said member 22, and thus the member 22 is bent and deformed until the circular truncated cone part 2 is so formed.
