PURPOSE: A rear ferrule having a bellows shaped elastic unit and a pipe connecting member including the same are provided to obtain a buffer force or a compensation force relative to a change of an external force or external circumstances such as pressure or temperature by the elasticity of the bellows shaped elastic unit in a corrugated pipe shape and a bendable property. CONSTITUTION: A rear ferrule of a pipe connecting member comprises a connecting member main body, a driving nut, an electric potential ferrule, and a rear ferrule (40). The rear ferrule includes a nose unit (41), a tail unit (42), an outer circumferential surface (43), an inner circumferential surface (44), and corrugated units (45,46) in a bellows shape. The tail unit has a rear inclined surface (42b). A plurality of peaks and valleys are consecutively formed on the outer circumferential surface and the inner circumferential surface. The number of the peaks and valleys on the inner circumferential surface is greater than the number of the peaks and valleys on the outer circumferential surface. |
