A sheet member (24) which has superior fabricating ability to be put on easily in a predetermined position, and also an exhaust gas purifying device (10) having such a sheet member (24) are disclosed.
In the present invention, a sheet member (24) including inorganic fibers is provided, in which said sheet member (24) has a first and a second surface (26,28) substantially facing away from each other that are perpendicular to a direction of thickness of the sheet member (24). The first surface (26) has at least one lowest point and at least one highest point; and a maximum difference between the lowest and the highest point of the first surface (a maximum unevenness difference) h is 0.4 mm‰¦h‰¦9 mm.
In such sheet members (24), when the first surface (26) is placed in contact with another member, because the contacting area between the sheet member (24) and other member becomes small due to the unevenness formed on the first surface (26), frictional force occurring when the sheet member is moved horizontally against the other member is reduced. |
