To provide a cylindrical member structure for preventing the dislocation of the body of a cylindrical member from a heat insulating material even when adhesive is separated therefrom or it is not applied thereto.
A metal band member is spirally rolled up in the axial direction to form the cylindrical member. The cylindrical member 1 has a wavy uneven portion continuously formed on the peripheral wall face in the axial direction. On the inner periphery of the cylindrical member 1, the heat insulating material 3 is mounted with the adhesive. The cylindrical member 1 has a bent portion 9 at an end 7 for preventing the fall (jump) of the heat insulating material 3 off/out of the cylindrical member 1 when the adhesive of the heat insulating material 3 is separated therefrom.
