Patent ID: 7263827

Claim:
A heat insulator attaching structure for a vehicle exhaust pipe, comprising: a heat insulator with a cross-section orthogonal to an extending direction thereof being curved substantially into an arc shape is attached to an exhaust pipe of a vehicle engine so as to allow distance therebetween; an attachment member attached to an inner-peripheral face of the heat insulator, the attachment member being formed with a single curved arc-shaped contact portion and a pair of attachment portions, the attachment portions being formed on outward sides of the arc-shaped contact portion in a radial direction thereof so as to allow distance therebetween for attaching the attachment member to the inner-peripheral face of the heat insulator, an inner-peripheral face of the arc-shaped contact portion of the attachment member contacting an outer-peripheral face of the exhaust pipe; and a band member fitted around an outer-peripheral face of the arc-shaped contact portion of the attachment member and the outer-peripheral face of the exhaust pipe, thereby fastening the attachment member to the exhaust pipe, wherein the heat insulator, the attachment member, and the band member are separate elements.
