Claims

[Claims for Utility Model Registration] (1) A support flange is provided at the end of one pipe, and a connection flange facing the support flange is provided at the end of the other pipe, and a spherical sliding member is provided at the base of the connection flange. The bearing surface forms a flared part formed on the inner peripheral surface, and between the support flange of one pipe and the flared part of the other pipe, the end face abuts the support flange and a spherical shape formed on the outer peripheral surface. In a pipe joint device that includes a sealed bearing whose sliding surface is in sliding contact with a sliding receiving surface of a flared portion, and in which both flanges are connected by a tightening means through an elastic member, the inside of the inner circumferential surface of the sealed bearing is A pipe joint device characterized in that a support flange forming an annular space and abutting an end face of a seal bearing is perpendicular to the axial direction of one pipe. (2) A support flange is provided at the end of one pipe, and a connection flange facing the support flange is provided at the end of the other pipe, and a spherical sliding receiving surface is provided on the inner peripheral surface of the end of the other pipe. The end surface is in contact with the support flange between the support flange of one pipe and the flare part of the other pipe, and the spherical sliding surface formed on the outer peripheral surface is in contact with the support flange of the other pipe. In a pipe joint device in which a sealed bearing is interposed in sliding contact with a sliding receiving surface and both flanges are connected by a tightening means via an elastic member, an annular space is formed inside the inner circumferential surface of the sealed bearing, A pipe joint device characterized in that a support flange that contacts the end face of a sealed bearing is orthogonal to the axial direction of one pipe.
