To provide a hermetically sealing device that sufficiently exerts a necessary characteristic.SOLUTION: A hermetically sealing device 10 includes: a main body portion 3; a first lip 41 projecting from the main body portion 3; and a second lip 42 projecting from the main body portion 3 and disposed on the inner side than the first lip 41 in the radial direction of the first lip 41. The first lip 41 and the second lip 42 extend from the main body portion 3 toward one of an inner member and an outer member. First grease G1 is applied to the surface of the first lip 41, and second grease G2 is applied to the surface of the second lip 42. The characteristic of the first grease G1 is different from that of the second grease G2.SELECTED DRAWING: Figure 2

    【課題】必要とされる特性を充分に発揮することができる密封装置を提供すること。【解決手段】密封装置10は、本体部3と、本体部3から突出する第1リップ41と、本体部3から突出し、第1リップ41よりも第1リップ41の半径方向の内側に位置する第2リップ42と、を備え、第1リップ41および第2リップ42は、本体部3から内側部材または外側部材の一方に向かって延びており、第1リップ41の表面に塗布された第1グリスG1と、第2リップ42の表面に塗布された第2グリスG2と、を備え、第1グリスG1の特性と、第2グリスG2の特性とは、互いに異なる。【選択図】図2
