Claims

[Claims for Utility Model Registration] 1. Two planes a including both left and right opening end faces 4 and 5.
, b intersect with each other in the form of a symmetrical short cylinder, and is made of a slightly elastically deformable heat insulating material. 2. The split-type elbow heat insulating cover according to claim 1, wherein the unit heat insulating cylinder 1 has a cylinder wall cut out at the shortest generatrix 7 position thereof. 3. The split type elbow insulation cover according to claim 1, wherein the unit insulation cylinder 1 has a cylinder wall cut out at the position of the shortest generatrix line 7, and a cut groove is provided on the inner surface of the cylinder wall opposite thereto. 4. The split-type elbow heat insulating cover according to claim 1, wherein the unit heat insulating cylinder 1 is cut in the cylinder diameter direction including the shortest generating line 7 to form a half cylinder.
