Claims

[Claims for Utility Model Registration] 1. A substantially cylindrical filter provided in an exhaust path for guiding exhaust gas discharged from an internal combustion engine to the outside to collect unburned particulates in the exhaust gas; and the substantially cylindrical filter. An exhaust gas purification device consisting of multiple sheathed heaters arranged around the entire outer circumference of a shaped filter. 2 The plurality of sheathed heaters are arranged such that a substantially horseshoe-shaped sheathed heater having an inner diameter of about half the diameter of the filter is installed in front of the suction part and behind the exhaust part of the filter, and has an inner diameter slightly larger than the diameter of the filter. 2. The exhaust gas purification device according to claim 1, wherein a plurality of substantially horseshoe-shaped sheathed heaters having circular arc portions are arranged at equal intervals around the outer circumference of the filter. 3. The plurality of substantially horseshoe-shaped sheathed heaters are arranged with each end facing in the same direction, and each end is fitted into a support plate installed on the outside of the filter to form an integrated body. The exhaust gas purification device according to claim 2, characterized in that: 4 In the plurality of sheathed heaters, a substantially horseshoe-shaped sheathed heater having an inner diameter of about half the diameter of the filter is installed close to the front of the suction part and the rear of the exhaust part of the filter, and a plurality of rod-shaped sheathed heaters 2. The exhaust gas purification device according to claim 1, wherein the filters are arranged in parallel in the axial direction of the outer periphery of the filter. 5. The rod-shaped sheathed heater includes an annular support frame installed in front of the suction part of the substantially cylindrical filter;
Both ends of the sheathed heaters are fitted into an annular support frame installed at the rear of the exhaust section, and the two approximately horseshoe-shaped sheathed heaters placed at the front and rear are also fitted with both ends of the annular support frames at the front and back, forming an integrated structure. 5. The exhaust gas purification device according to claim 4, wherein the exhaust purification device comprises:
