Abstract
An exhaust pipe holding member includes an annular portion, an annular outward protruding portion (protruding piece), and a flange portion. The annular portion is formed with a through hole penetrating from one end through the other end. The outward protruding portion protrudes peripherally outward from the outer peripheral surface of the annular portion. The flange portion is disposed closer to one end than to the outward protruding portion, extending peripherally outward from the outer peripheral surface of the annular portion, and is configured to have a thickness greater than that of the outward protruding portion. The flange portion is formed with an annular groove surrounding the through hole.
