<P>PROBLEM TO BE SOLVED: To provide a deodorization apparatus capable of preventing a gas not heated by a heater from flowing into the neighborhood of a deodorization part. <P>SOLUTION: This deodorization apparatus is provided with the heater 1, the deodorization part 2 and a heat insulation material 4 interposed between an internal pipe and an apparatus body 3. The heat insulation material 4 is provided with a cylindrical body 41 surrounding the internal pipe, the heater 1 and the deodorization part in a peripheral direction of the internal pipe; and a lid body 42 having at least one part stored in one end close to the deodorization part 2 of the cylindrical body 41 and closing one end of the cylindrical body 41. Recessed parts 45c, 46c having thickness of an end mounted with the lid body 42 made smaller than the other parts are provided on an inner surface of the cylindrical body 41. The lid body 42 is formed to a shape corresponding to an inner peripheral surface of the cylindrical body 41, and a contact surface of the lid body and the cylindrical body 41 has a surface along a thickness direction of the lid body 42 and a surface crossing in the thickness direction over the whole periphery of the lid body 42, respectively. Since a gap between the lid body 42 and the cylindrical body 41 is bent along the thickness direction of the lid body 42, permeation of gas is inhibited. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
