The structure of the dust-proof member 6 may be a cover structure, a mesh structure, or the like, but is not limited thereto as long as the dust-proof member can block external foreign matter.

The specific connection relationship between the dust-proof member 6 and other components may be set in various ways, for example:

in a possible realization, the dust protection 6 is removably associated with the support wall 402, the end of the operating element 2 being located inside the support wall 402.

In practical application, the dust-proof part 6 and the supporting wall 402 are always in a sleeved sealing state, and when the operating part 2 needs to be driven to adjust the position of the adjusting part 1, the dust-proof part 6 only needs to be detached from the supporting wall 402, and then the operating part 2 in the dust-proof part is rotated. After the position of the adjusting member 1 is adjusted, the dust-proof member 6 is connected to the support wall 402 and sealed.

Through so setting up, can further improve the dustproof effect of casing 4 in daily use, simultaneously, when needs adjustment regulating part 1 position, only need with dustproof 6 pull down, the tip of rotating tooth operating parts 2 can, very convenient.

For the connection between the dust-proof member 6 and the supporting wall 402, for example, the dust-proof member 6 may be made of rubber material and sleeved on the supporting wall 402, or the dust-proof member 6 may be bonded to the supporting wall 402, which is not listed here.

In another possible implementation, the dust-proof member 6 is connected to the end of the operation member 2 located outside the mounting tube 3, and the dust-proof member 6 is provided with a through hole for passing through the operation member 2.

In practical applications, when the end of the operating element 2 needs to be rotated to adjust the position of the adjusting member 1, the operating element 2 only needs to be rotated by the operating portion 201 of the operating element 2. Through so setting up, improved the operating efficiency, when needs rotate operating parts 2, need not to carry out other loaded down with trivial details operations.

In this implementation, the dust-proof component 6 may be made of rubber and sleeved on the supporting wall 402, or the dust-proof component 6 may be adhered to the supporting wall 402. It should be understood that, since the dust-proof member 6 is provided with the through hole for passing through the operation member 2, the sealing property between the operation member 2 and the dust-proof member 6 needs to be improved, and based on this, in order to improve the sealing property between the operation member 2 and the dust-proof member 6, the operation member 2 and the dust-proof member 6 may be provided as a clearance fit.

Further, in order to improve the sealing performance between the adaptor 5 and the dust-proof member 6 and prevent the contaminants and moisture from entering the housing 4 or the installation tube 3, as shown in fig. 2, the apparatus further includes: and a seal 7. The seal 7 is arranged between the adapter part 5 and the dust part 6.

The sealing member 7 may be a sealing ring, a sealing sleeve, or the like, but is not limited thereto as long as it can seal between the adaptor 5 and the dust-proof member 6.

Correspondingly, the embodiment of the application also provides a vehicle, and the vehicle comprises the steering adjusting device in the embodiment.
