- the exhaust passage heating unit 170 is connected to the exhaust pipe 41 as shown in Figs. 0 (exhaust passage)
- a cylindrical heating main body part 171 disposed adjacently so as to cover the inner wall surface 410a, and is formed integrally with the outer periphery of the heating main body part 171 in an annular and flange-like shape.
- the mounting portion 172 is formed by a connector 173 provided at a radially outer end of the mounting portion 172.
- the exhaust passage heating unit 170 has a heating body such that the outer shell 171b is in close contact with the inner wall surface 410a or a slight gap is formed between the inner shell 410a and the inner wall surface 410a.
- the mounting part 172 With the part 171 inserted into the exhaust passage and the O-ring 200 mounted, the mounting part 172 is sandwiched between the flange parts 412 and 412, and 412 and 422, and fastened by the above-described clamp mechanism 300.
- the exhaust passage is shut off from the outside and vacuum sealed.
- the attachment / detachment operation can be easily performed by providing the attachment portion 172 to the heating main body portion 171.
- the mounting portion 472 is formed by flanges 472a and 472b joined to the outer shell 471b, and a resistance heat is generated between the two flanges 472a and 472b.
- the lead 47 1 c ′ for energization connected to the body 47 1 c and the lead 4 71 c ′ as a temperature sensor for measuring the temperature of the resistance heating element 47 1 c are sandwiched, and the connector 4 7 Up to 3 have been drawn. That is, the flanges 472a and 472b are not completely closed between the two but open to the outside.
- the connector 473 is connected with a power supply cable 90 to the lead 471 c and a cable 9 to be connected to the measuring instrument to the lead 471 c. 1 is to be connected.
