Swinging through spherical motion such as capable joint structures for dust seal

摘要

(57) Abstract Objective Simultaneously with attachment to partner part bellows section ourIt makes that it reverses dynamically possible. Constitution Fluctuation or spheric motion etc possible axis 11 is denseIt is installed with the tubed housing 10 which surrounds the re,From the adapter unit 1 which fits to housing 10 to axial 11 side directionThe ke te reversing the bellows section 3 of the conical condition which extends, in the Tipdasu which makes the seal lip section 2 which is provided axis contact 11In toshiru, in seal lip section 2 the said seal lipFrom the axis 11 which extends from section 2 furthermore facing toward inside radialTo provide the support section 4 of small inside diameter, when attaching the partnerIn axis 11 side seal lip section 2 compared to support section inside4 touching, this while reversing bellows section 3, it attaches, it is denseWith it makes possible.
