Patent ID: 7506713

Claim:
A heat exchanger for motorcycle use mounted on a motorcycle in which heat is exchanged between air and a heating medium flowing inside the heat exchanger, wherein the heat exchanger is fixed to a motorcycle body via a fixing member; the fixing member includes a through-hole into which a portion of the motorcycle body is inserted via a cylindrical grommet capable of being elastically deformed and a collar; a cylindrical burring portion, which protrudes onto one side, is formed in an inner circumferential edge portion of the through-hole; the grommet is inserted into the through-hole so that the grommet contacts with the inner circumferential edge portion of the through-hole; and a forward end portion of the burring portion is directed outward in the radial direction with respect to the inner circumferential edge portion of the through-hole to avoid contact between an inner circumferential surface of the forward end portion of the burring portion with a cylindrical portion of the grommet.
