Abstract (en)

An assembly in which a holding and sealing member which is formed by combining plural mat members is placed on a circumferential surface of an exhaust gas treatment member. The first mat member 125A has a top end face 148A, a bottom end face 149A and a side end face 150A, and a protrusion part 160 is formed on the side end face 150A. Further, the second mat member 125B has a top end face 148B, a bottom end face 149B and a side end face 150B, and a recess part 170 is formed on the side end face 150B. By fitting the protrusion part 160 and the recess part 170 together, the first mat member 125A and the second mat member 125B are joined together at the side end faces 150A and 150B. the protrusion part 160 of the first mat member 125A has a contour part Rl extending from a point A as a starting point and a contour part R2 extending from a point B as a starting point. The first point A is nearer to the top end face 148A of the first mat member 125A than the second point B. An angle ± between a line segment P1 starting from the first point A and a line segment P2 passing through the first point A on the first contour part R1 is such that ± > 90°. An angle ² at the second point B on the second contour part R2 is such that ² < 90°.
