The rear nozzle body 172 has a first steam jetting port 172b formed therethrough along the longitudinal direction thereof. Four first steam jetting ports 172b are formed at the edge of the rear nozzle body 172 and are evenly spaced from each other.

The front nozzle body 173 is formed in a cylindrical shape having the same diameter as that of the rear nozzle body 172 and is spaced a predetermined distance forward of the rear nozzle body 172. The second steam inlet 173a is formed to pass through the front nozzle body 173 along the longitudinal direction of the main body 173. The diameter of the second steam inlet 173a is larger than the diameter of the first steam inlet 172b . Four second steam injection openings 173a are formed at the edges of the front nozzle body 173 and are evenly spaced from each other.

In the present embodiment, the first steam injection port 172b and the second steam injection port 173a are not located on a straight line, and are formed so as to be shifted from each other such that the progress direction in which steam is discharged is not straight. That is, as shown in FIGS. 7 and 8, when the nozzle body 171 is viewed in the longitudinal direction, the second steam jetting port 173a is disposed between the first steam jetting ports 172b.
