Abstract
The present invention provides a dust cover which is provided between an engine room and the driver's seat such that, when a steering shaft provided under a steering wheel of a vehicle is installed passing through a vehicle frame, the steering shaft passes through the dust cover. The dust cover is characterized by comprising: a pair of bearings coupled to the steering shaft; a pair of bearing races provided to surround outer circumferential surfaces of the bearings; a ring-shaped fixing cap forcibly inserted into the bearing races through both sides of an opening by interference fitting, thereby fixing the bearings; and an integrally formed seal part having through-holes to which the bearing races are coupled.

In a dust cover through which a steering shaft passes when the steering shaft provided under the steering wheel of a vehicle is installed through a vehicle frame, the dust cover characterized in that
- the dust cover includes a rolling part (100) coupled to the steering shaft (S) and a seal part (200) provided in a gap between a dash panel of the vehicle frame and the steering shaft (S),
- the seal part (200) includes a plate (230) forming the bottom, an upper protrusion part (210) protruding upward in a conical shape on the upper surface of the plate (230), and a lower protrusion part (220) protruding downward in a conical shape on the lower surface of the plate (230), and
- a through-hole (270), to which the rolling part (100) is coupled, is disposed in each of the upper protrusion part (210) and the lower protrusion part (220),
- wherein the seal part (200) is characterized in that
- a long portion (211) having a long length is formed on an inclined surface of the upper protrusion part (210), a long portion (221) having a long length is formed on an inclined surface of the lower protrusion part (220), the long portion (211) of the upper protrusion part (210) and the long portion (221) of the lower protrusion part (220) are provided to face each other, the long portions (211, 221) have annular wrinkle parts (212, 222) formed to be concave or formed to convexly project, and the inside of the upper protrusion part (210) and the lower protrusion part (220) is empty, and
- wherein the seal part (200) includes
- a side wall part (240) protruding upward along the circumference of the plate (230),
- a flange wing part (250) extending outward from an upper end of the side wall part (240) so as to be placed on the dash panel of the vehicle frame, and
- an impact mitigation gap (280) formed between the upper protrusion part (210) and the side wall part (240).
