Claim:
An exhaust-gas purifying apparatus, comprising: an outer cylinder; a plurality of cylinder-shaped supports disposed in the outer cylinder, and having an outer peripheral surface and an inner peripheral surface, at least two of the neighboring cylinder-shaped supports contacting with each other with the outer peripheral surfaces; and a catalytic layer loaded on at least one of the outer peripheral surface and inner peripheral surface of the cylinder-shaped supports, wherein the cylinder-shaped supports in contact, but not fitted into the outer cylinder, are inscribed in a circle having a diameter superior to an inside diameter of the outer cylinder, at least one of the cylinder-shaped supports has a ring-shaped cross-section with a cut-off having a peripheral length such that when the at least one of the cylinder-shaped supports is in elastically deformed state, the cylinder-shaped supports are inscribed in a circle having a diameter inferior to the inside diameter of the outer cylinder, wherein the cylinder-shaped supports are combined into a plurality of groups, and the groups are disposed in the outer cylinder at predetermined intervals in the axial direction of the outer cylinder and the groups of the cylinder-shaped supports are disposed out of phase in the axial direction of the outer cylinder.
