The susceptor 30 may be inserted into the through hole 54 from the one surface 51 (see FIG. 3) of the flange 50 toward the other surface 53 thereof. The susceptor 30 may be inserted into the through hole 54 from the other end of the susceptor 30. The other end 35a of the susceptor 30 may be inserted into the through hole 54 in the state in which the leg 35 (see FIG. 4) is not formed.

When the susceptor 30 is inserted into the through hole 54, the sloping surface of the other end 35a may be inserted into the through hole 54 while sliding on the inner circumferential surface of the flange 50. The other end 35a of the susceptor 30 may extend through the through hole 54, and may be exposed at the other surface 53 of the flange 50. The flange 50 may be made of an elastic material. For example, the flange 50 may be made of plastic.

After the other end 35a of the susceptor 30 passes through the through hole 54, the recessed portion 33 may be inserted into the through hole 54. The recessed portion 33 may be forcibly fitted into the through hole 54 in the flange 50. The diameter d4 of the through hole 54 may be set to have dimensions such that the recessed portion 33 is capable of being inserted into the through hole 54 but the susceptor body 31 is incapable of being inserted into the through hole 54. The inner circumferential surface of the flange 50 may surround the outer circumferential surface of the recessed portion 33 in the state of being in close contact therewith.

The retainer surface 331 may catch on the one surface 51 of the flange 50, and thus may not pass through the through hole 54 (see FIG. 3). The retainer surface 331 may be supported by the one surface 51 of the flange 50 (see FIG. 3).

Consequently, it is possible to seal the gap in the through hole 54 between the susceptor 30 and the flange 50, and it is possible to prevent liquid from leaking between the susceptor 30 and the flange 50.

Referring to FIGS. 6 and 7, after the other end 35a of the susceptor 30 is exposed at the other surface 53 of the flange 50, the other end 35a of the susceptor 30 may be bent radially outwards so as to form the leg 35. The other end 35a of the susceptor 30 may be formed so as to have a small thickness. The susceptor 30 may be made of metal, which has a certain rigidity but is sufficiently thin so as to be easily torn. For example, the susceptor 30 may be made of stainless steel.

A presser 60 may include a presser body 64 and a bit blade 65. The bit blade 65 may project radially outwards from the outer circumferential surface of the presser body 64.

The presser body 64 may have the form of a cylinder. The diameter of the presser body 64 may be smaller than or similar to the diameter of the susceptor hole 34. The presser body 64 may be inserted into the susceptor hole 34. The bit blades 65 may be formed so as to be gradually widened in a direction opposite the direction in which the presser 60 is inserted.

The leg 35 may be formed by pressing the other end 35a of the susceptor 30 around the susceptor hole 34 using the presser 60. The presser 60 may have rigidity higher than that of the susceptor 30. When the presser body 64 is inserted into the susceptor hole 34, the bit blades 65 may press the other end 35a of the susceptor 30. When the bit blades 65 press the other end 35a of the susceptor 30, the other end 35a of the susceptor 30 may be bent outwards while being torn, thereby forming the legs 35. The portions of the other end of the susceptor 30 at which the legs 35 are not formed are supported by the retainer protrusions 531, whereby the portions of the other end 35a may be prevented from being torn or bent outwards. The susceptor hole 34 may enable the other end 35a of the susceptor to be easily bent outwards.

Each of the plurality of legs 35 may be bent radially outwards, and may thus be disposed in a corresponding one of the plurality of retainer grooves 532. The legs 35 may extend in a direction intersecting the longitudinal direction of the susceptor 30. The other surface 53 of the flange 50 may support the legs 35. Each of the legs 35 may be disposed in a corresponding retainer groove 532 between a pair of adjacent retainer protrusions 531. The pair of retainer protrusions 531 may be disposed at or in close contact with the two lateral side portions of the leg 35.

Accordingly, it is possible to prevent the susceptor 30 from rotating with respect to the flange 50 when the stick 200 (see FIG. 1) is inserted into or separated from the aerosol-generating device. Furthermore, it is possible to prevent the susceptor 30 from being separated from the flange 50 by fixing the susceptor 30 to the flange 50 in a simple manner.

Referring to FIGS. 7 and 8, the sensing device 40 may be inserted into the susceptor through the susceptor hole 34. The sensing device 40 may be inserted into the susceptor after the legs 35 are formed. The temperature sensor 41 may be inserted into the susceptor 30, and the sensor cover 43 may plug the susceptor hole 34. The sensor cover 43 may be bonded to the susceptor 30. The conductive pin 42 connected to the temperature sensor 41 may be exposed to the outside of the susceptor 30 through the sensor cover 43.

Referring to FIG. 9, the first rib 241 and the second rib 242 may project radially inwards from the inner circumferential surface of the lower portion of the pipe 22. Each of the first rib 241 and the second rib 242 may have the shape of a ring. The first rib 241 may be formed at the lower end of the pipe 22. The second rib 242 may be formed at the lower portion of the pipe 22 above the first rib 241. A rib hole 246 may be formed by perforating the center of the first rib 241.

The flange 50 may be disposed in the mount space 244 defined between the first rib 241 and the second rib 242. The flange 50 may be forcibly fitted into the mount space 244, or may be insert-molded in the mount space 244. The first rib 241 may cover the periphery of the other surface 53 of the flange 50 in the state of being in close contact therewith. The outer circumferential surface of the flange 50 may be in close contact with the inner circumferential surface of the pipe 22 in the mount space 244 defined between the first rib 241 and the second rib 242. The other side of the susceptor 30, the conductive pin 42, the retainer protrusion 531, and the retainer groove 532 may be exposed through the rib hole 246.

A first projection 243 may be formed so as to project upwards from the first rib 241. The first projection 243 may circumferentially extend along the shape of the first rib 241. The first projection 243 may have a shape corresponding to the first depressed portion 533. The first projection 243 may be formed in the shape of a ring. The first projection 243 may be spaced inwards apart from the inner circumferential surface of the pipe 22. The first projection 243 may be inserted or forcibly fitted into the first depressed portion 533.

A second projection 245 may project outwards from the first projection 243. The second projection 245 may be connected to the first projection 243. The second projection 245 may have a shape that is convex outwards from the first projection 245. The second projection 245 may be one of a plurality of second projections. Each of the plurality of second projections 245 may have a shape corresponding to one of the second depressed portions 534. The second projections 245 may be inserted or forcibly fitted into respective second depressed portions 534.
