  • the ring-shaped member 72 is disposed between the chamber 50 and the second member 200.
  • the ring-shaped member 72 can function as a support portion that abuts against the bottom portion 56 of the chamber 50 and supports the chamber 50.
  • the ring-shaped member 72 can be made of, for example, a resin, and in particular, can be made of polycarbonate, ABS resin, PEEK, or a polymer alloy containing multiple types of polymers, or a metal such as aluminum.
  • the ring-shaped member 72 is preferably made of PEEK. Note that the ring-shaped member 72 may have a notch through which the shaft portion 36a of the first member 36 passes, instead of the through hole 72a.
  • the heater cushion 74 may be formed of an elastic material such as silicone rubber. When using silicone rubber, the preferred Shore A hardness range is 40 to 60, and can be selected appropriately depending on the deformation of the heater cushion 74.
  • the heater cushion 74 is configured to be positioned and fixed to the inner housing 10 or a fixing part 22 fixed to the inner housing 10.
  • the heater cushion 74 has a through hole 74a in the center, into which the shaft part 36a of the first member 36 is inserted.
  • the heater cushion 74 may have a notch through which the shaft part 36a of the first member 36 passes, instead of the through hole 74a.
  • the heater cushion 74 is formed of an elastic member such as silicone rubber as described above, and is configured to bias the chamber 50 toward the insertion guide member 34, i.e., in the positive direction of the Z axis, via the second member 200 and the ring-shaped member 72. Specifically, when the insertion guide member 34 is inserted into the housing and abuts against the flange portion 52a, the heater cushion 74 is compressed by the insertion guide member 34 and the chamber 50, biasing the chamber 50 toward the insertion guide member 34. In this way, the heater cushion 74 presses the chamber 50, the first member 36, and the second member 200 toward the housing such as the inner housing 10 or a member fixed to the housing.
  • the heater cushion 74 fixed to the fixing portion 22 is elastically deformed, so that the heater cushion 74 can maintain a state in which it biases the chamber 50 within the inner housing 10.
  • the heater cushion 74 biases the chamber 50 via the second member 200 and the ring-shaped member 72, so that the heater cushion 74 and the chamber 50 do not come into contact with each other. This makes it difficult for heat from the chamber 50 to be transferred to the heater cushion 74, so deterioration of the heater cushion 74 can be suppressed, and heat loss from the chamber 50 can also be suppressed. From a similar perspective, it is preferable that the ring-shaped member 72 be formed from a material with a lower thermal conductivity than the heater cushion 74.
  • the first member 36 is configured so that the shaft portion 36a passes through an opening in the fixed portion 22 fixed to the inner housing 10.

  • the fixed portion 22 has a flat surface 22a that faces the flat surface 360 of the shaft portion 36a.
  • the flat surface 360 of the shaft portion 36a abuts against the flat surface 22a of the fixed portion 22, thereby preventing relative rotation of the chamber 50 with respect to the fixed portion 22.
  • the second member 200 presses the first member 36 from the side in the direction (axial direction) in which the first member 36 extends outside the chamber 50.
  • the frictional force caused by this pressing acts as a stopper that suppresses the positional displacement of the first member 36, particularly the displacement in the axial direction.
  • the second member 200 can suppress the displacement of the first member 36 in both the front-rear direction and either one of the directions in which the first member 36 extends.
  • a gas flow path may be formed inside the chamber 50 based on the shape of the first member 36, and the axial displacement of the first member 36 extending from the inside to the outside of the chamber 50, particularly the displacement of the first member 36 relative to the chamber 50, may have a negative effect on the heating efficiency.
  • the second member 200 can also suppress such a negative effect.
  • the first member 36 may be fixed to the chamber 50 by an adhesive or the like, but the adhesion may weaken due to deterioration of the epoxy resin contained in the adhesive. Even in such a case, the second member 200 can suppress the above-mentioned negative effect.

  • FIG. 11B is a plan view of the second member 200.
  • FIG. 11C is a cross-sectional view taken along line 11C-11C of FIG. 11B.
  • the second member 200 comprises an abutting portion 210 that abuts against the first member 36, and a base portion 220.
  • the abutting portion 210 is configured such that its end portion 211 abuts against the shaft portion 36a of the first member 36.
  • the material of the second member 200 is not particularly limited as long as it can suppress axial displacement of the first member 36.
  • the abutting portion 210 presses the first member 36 from the side of the first member 36 to suppress axial displacement of the first member 36, so high machining precision is required for the end 211 of the abutting portion 210.
  • the second member 200 contains a metal, and it is more preferable that the second member 200 is a metal member.
  • the metal constituting the second member 200 is not particularly limited, but can be, for example, stainless steel.

It is preferable that the contact surface, which is the end surface of the end portion 211 of the contact portion 210, is configured so that there is substantially no gap between the end portion 211 and the side surface of the shaft portion 36a.
  • the end portion 211 of the contact portion 210 since the shaft portion 36a is cylindrical, the end portion 211 of the contact portion 210 has an arch-shaped end surface with a curvature radius equal to the radius of the cross section of the shaft portion 36a (see FIG. 11B).
  • the second member 200 is configured to contact the first member 36 from multiple directions. From this viewpoint, it is more preferable that the second member 200 has multiple contact portions 210 having shapes corresponding to the side surfaces of the shaft portion 36a.
  • the base 220 is a member that supports the abutment portion 210.
  • the base 220 can function as a connection portion that supports and connects the multiple abutment portions 210.
  • four abutment portions 210 are formed on the second member 200, but the number of abutment portions 210 is not particularly limited and can be one, two, three, or five or more.
  • the base 220 is preferably annular. In this way, by having at least a portion of the second member 200 be annular, the second member 200 can be easily positioned around the first member 36 and can be easily attached. Note that the base 220 does not have to be annular, and may have a polygonal outline shape, for example.
  • the base 220 is formed along the surface S10.
  • the abutment portion 210 is a member extending from the abutment surface in a direction inclined with respect to the axial direction.
  • the abutment portion 210 is arranged along a conical surface. In this way, the abutment portion 210 is formed inclined with respect to the surface S10 and the axial direction, and can be elastically deformed in a direction perpendicular to the inclination (see arrow A10).
  • the shaft portion 36a when the shaft portion 36a is inserted into the second member 200, the shaft portion 36a can be pressed by elasticity and fixed more stably. From this viewpoint, it is preferable that the second member 200 has elasticity.
