PURPOSE:To provide the sealing structure of a rotary shaft where a sealing part is subjected to neither heat generation nor abrasion. CONSTITUTION:A support member 12 for supporting an atomizing nozzle 10 and a rotary shaft and an elastic member 13 for surrounding the circumference of the rotary shaft 11 are provided, and pressure inside a casing is increased by injection from the atomizing nozzle 10, and a seal is separated during rotation of the shaft since the elastic member and the shaft are constituted to separate from each other at the time of rotation of the shaft, and thereby the sealing part may not generate heat by friction. |
