As preferably, described base side edge is provided with slotting ear, and inserting ear is inverted "L" shaped, and dust boot lateral edges is provided with card ear, and Ka Ershang is provided with the draw-in groove matched with slotting ear.Base side edge is provided with slotting ear, and dust boot side arranges card ear, and the slotting ear in inverted "L" shaped can insert in the draw-in groove on card ear, and it is spacing that draw-in groove can insert ear to card, realizes being connected together of dust boot and base, be convenient to assembling and the dismounting of dust boot and base.
As preferably, described dust boot lower edge and circular groove inwall flush fit.
As preferably, base upper surface is kidney ellipsoid, and base axis direction overlaps with the projection in the horizontal plane of steering gear input shaft axis; Described circular groove is in the kidney ellipsoid identical with base upper surface shape.
As preferably, seal groove comprises storage tank and gas guide groove, is provided with liner in storage tank, and dust boot lower end embeds in circular groove, gas guide groove and circular groove conducting.
Therefore, steering gear input shaft dust boot of the present utility model possesses following advantage: embed when dust boot lower end after in the circular groove on base, gas guide groove and circular groove conducting, run through in base lower end and deflation hole is set, deflation hole and gas guide groove conducting, along with extruding when installing, dust boot extruding liner, extrude base, the gas in seal groove is discharged by deflation hole simultaneously.When dust boot is assemblied in deflector, the base of kidney ellipsoid and dust boot can increase body openings scope, adapt to the deflector of different angle, and increase sealing effectiveness by circular groove, seal groove and liner.Dust boot upper surface projection is provided with several seal rings identical with dust boot shape, seal ring raises up and forms the kidney ellipsoid identical with dust boot shape, seal ring compresses and is fitted on vehicle body, further increase sealing and dustproof effect, the noise of machinery space and propons is not easily delivered to driving compartment.
