  • the flange portion 90a and the end face support portion 76 restrict the axial movement of the heat insulating portion 32. This prevents the heat insulating portion 32 from moving endlessly in the axial direction, and prevents the heat insulating portion 32 from colliding with another member (for example, the inner housing 10 or the chamber 50).
  • the gasket 90 and the heater so that the axial distance between the flange portion 90a and the end face support portion 76 of the heater cushion 74 is substantially the same as the axial length of the support member 32a of the heat insulating portion 32.
  • the cushion 74 may be positioned. In this case, both ends of the support member 32a of the heat insulating portion 32 come into contact with both the flange portion 90a and the end face support portion 76, respectively. Even in this case, although the frictional force from the flange portion 90a and the end face support portion 76 is applied to the support member 32a, the heat insulating portion 32 can move in the first direction.
  • the ring 80 is arranged inside the first end portion 39a of the heat insulating portion 32, the peripheral wall portion 75 of the heater cushion 74 is arranged outside the first end portion 39a, and the second of the heat insulating portion 32 is arranged.
  • the gasket 90 is arranged inside the end 39b.
  • the impact when the ring 80, the heater cushion 74, or the gasket 90 comes into contact with the heat insulating portion 32 is dispersed to both ends, and it is possible to prevent the 32 from being destroyed.
  • the present invention is not limited to this, and the movement of the heat insulating portion 32 in the first direction is restricted to at least one of the inside and the outside of only one of the first end portion 39a and the second end portion 39b of the heat insulating portion 32. Members may be provided.
  • the flavor aspirator 100 of the present embodiment has a so-called counterflow type air flow path in which the air flowing in from the opening 52 of the chamber 50 is supplied to the end face of the consumable material 110, but the chamber is not limited to this. It may have a so-called bottom flow type air flow path in which air is supplied from the bottom 56 of the 50 into the chamber 50.
  • the heating element 42 is not limited to the resistance heating type, and may be an induction heating type. In that case, the heating element 42 can heat the chamber 50 by induction heating. Further, when the consumption material 110 has a susceptor, the heating element 42 can heat the susceptor of the consumption material 110 by induction heating.
