特徴とする回転軸シール装置。 In a rotary shaft sealing device in which an oil seal is inserted between a seal holder provided integrally with a housing and a rotary shaft penetrating the seal holder and protruding outward to isolate the inside and outside of the housing, the seal holder first and second annular protrusions forming a minute gap with the outer peripheral surface of the rotating shaft are sequentially formed toward the oil seal, and an air supply source is connected between the first and second annular protrusions. A rotary shaft sealing device characterized in that a first annular chamber is formed, and a second annular chamber communicating with a drain passage is formed between the second annular projection and the oil seal.
