する密封装置。 The outer cylindrical part has a stepped large diameter part and a small diameter part,
Consists of a seal member formed by baking a rubber elastic body around the outer periphery of a metal ring having a radius extending in the radial direction, and a sleeve member formed by baking a rubber elastic body around a substantially U-shaped metal ring. In the sealing device, the sealing member includes a sealing lip that slides on the sleeve member on the inner circumferential side to seal the sealing fluid, a dust lip that prevents dust from entering from the outside air, and an annular protrusion that slides into contact with the end surface of the sleeve member. 1. A sealing device comprising: an outer circumferential portion of the sleeve member being bent to form a minute gap with a concave portion and a convex portion provided in a small diameter portion of the sealing member.
