Abstract:
1. An exhaust purifying apparatus comprising a particulate filter for collecting particulates in an exhaust gas, the particulate filter including partitioning walls for forming a passage, the partitioning walls being made of a porous material, and end portions of adjacent partitioning walls being brought close to each other so as to narrow the respective passage formed by the partitioning walls so that the cross-sectional area of a flow path formed by the end portions of the adjacent partitioning walls is smaller than the cross-sectional area of a flow path formed by the remaining portions of the adjacent partitioning walls, wherein the particulate filter has extended portions that extend beyond both top ends of the partitioning walls from end surfaces of the particulate filter such that the extended portions prevent damage of the top ends of the partitioning walls when the particulate filter is being handled, wherein the end portions of the partitioning walls are combined together and the top ends of the partitioning walls are connected with each other so as to close one end surface of the passage, and wherein the extended portions are a portion of an outer peripheral wall of the particulate filter.
