Document Type and Number:
Japanese Patent JP2020079611
Kind Code:
A
Abstract:
To provide an airflow generation structure capable of further suppressing the entry of dust, and provide a sealing construction.SOLUTION: In a sealing construction 1, a fin structure 60 includes a body part 61 arranged in a clearance between a housing 53 on which an oil seal 20 is mounted and a hub 11 which extends over the outer periphery side of a boss part 14 rotatable around the axis passing through a through-hole 53h of the housing 53 and is formed integrally with the boss part 14, and rotatably mounted integrally with the boss part 14. The fin structure 60 further includes a plurality of vane parts 62 extending from an outer peripheral face 61g of the body part 61 to the outer periphery side for generating an airflow in a centrifugal direction perpendicular to the axis x when the boss part 14 is rotated, and a plate-like part 63 rotatably mounted integrally with the boss part 14 and provided between the body part 61 and the plurality of vane parts 62 and the housing 53 or the hub 11.SELECTED DRAWING: Figure 1
