Abstract

An exhaust manifold cover is provided with a plate-shaped cover member for covering at least a part of a heat source. The cover member has a first affixation section and a second affixation section, which are affixed so as to be in contact with the heat source. A bellows section in which ridges and grooves extending in a transverse direction perpendicular to a centerline passing through the first and second affixation sections are alternately formed is provided on the cover member at a position between the first and second affixation sections. The bellows section has formed therein a groove pair composed of two grooves having different widths of the two grooves composing the groove pair, the first groove which is near the first affixation section has a greater width than the second groove which is near the second affixation section.

Dependent claims

A heat source cover comprising a sheet-like cover member which covers at least part of a heat source,

wherein the cover member includes a first affixation section and a second affixation section which are fixed by contacting with the heat source,
wherein a bellows section, in which a ridge and a groove extending in a direction perpendicular to a center line passing through the first and second affixation sections are alternately formed, is provided between the first and second affixation sections of the cover member,
wherein an integrated value of the cross-sectional area perpendicular to the center line from a center point between the first affixation section and the second affixation section until the first affixation section is smaller than an integrated value of the cross-sectional area from the center point until the second affixation section,
wherein a pair of stripes configured by two grooves of different width or two ridges of different width is formed in the bellows section, and
wherein, among two stripes configuring the pair of stripes, a stripe closer to the first affixation section has larger width than a stripe closer to the second affixation section.
