<P>PROBLEM TO BE SOLVED: To provide a tubular body soundproof cover that does not tend to suppress elastic deformation of a tubular body, and a tubular body with the cover. <P>SOLUTION: A tubular body soundproof cover 2 includes a sound absorbing layer 3 disposed outside a tubular body 6 having tubular body-side curved sections 62f, 62r in the direction perpendicular to the axial direction, a surface layer 4 disposed outside the sound absorbing layer 3 in the direction perpendicular to the axial direction, and cover-side curved sections 5f, 5r disposed outside the tubular body-side curved sections 62f, 62r in the direction perpendicular to the axial direction, and having at least part of the sound absorbing layer 3 and at least part of the surface layer 4. The cover-side curved sections 5f, 5r have unbonded sections 50f, 50r in which the sound absorbing layer 3 and the surface layer 4 are not bonded over the entire lengths thereof in the circumferential direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
