Heat insulator

Abstract

A heat insulator includes a first covering part and a second covering part. The first covering part is configured to cover a bent part formed in an exhaust pipe of an internal combustion engine. The first covering part has a plurality of slits extending in a circumferential direction of the exhaust pipe. The plurality of slits are arranged with a given space from each other in a direction in which the exhaust pipe extends such that a plate part between slits is present between the plurality of slits. The second covering part covers the other part of the exhaust pipe than the bent part. At least a part of the second covering part is bonded to the exhaust pipe.
