The inner side of the surrounding wall 321 is connected to the friction ring block 31 and defines a limiting space 324 for receiving the friction ring block 31 and the friction unit 4. The limiting space 324 has a limiting opening 325 through which the limiting rotating shaft 1 penetrates, and an assembly opening 326 disposed along the axis L on a side opposite to the limiting opening 325. The end cap 323 is capped to the assembly opening 326. The mounting portion 322 has a mounting hole 327 adapted for mounting the mirror body 91.

The friction unit 4 includes a first friction group 41 between the friction ring block 31 and the limiting ring 12 of the limiting shaft 1 , and a gap between the friction ring block 31 and the abutting ring member 2 . Second friction set 42. The first friction group 41 and the second friction group 42 are both annular and sleeved on the limiting rod portion 111. The first friction group 41 has a first friction member 411 adjacent to the friction ring block 31, a first washer 412 adjacent to the first friction member 411, and a first washer 412 and the limit. A pad 413 between the bit rings 12. The second friction set 42 has a second friction member 421 adjacent to the friction ring block 31 and a second washer 422 adjacent to the second friction member 421. The pad 413 corresponds to the ring segment 113 and has a plurality of internal teeth 414 that engage the stop teeth 115 with each other. The stop teeth 115 and the inner teeth 414 prevent the pad 413 from rotating relative to the limit lever portion 111.

The first friction member 411 , the friction ring block 31 and the second friction member 421 are tightly clamped between the abutting ring member 2 and the limiting ring 12 . The first friction member 411 has a first friction surface 415 that is pressed against the friction ring block 31. The second friction member 421 has a second friction surface 423 that is pressed against the friction ring block 31. The surface roughness of the first friction surface 415 and the second friction surface 423 are different from each other.

The locking nut 5 is screwed to the locking rod portion 112 and is adapted to lock the limiting shaft 1 to a locomotive body 92.

When the present embodiment is assembled, the pad 413 of the friction unit 4 is first inserted into the ring segment 113 of the limiting shaft 1, and the first washer 412, the first friction member 411, and the friction are sequentially The ring block 31, the second friction member 421 and the second washer 422 are fitted into the limiting rod portion 111. Then, the resisting ring member 2 is screwed to the screw lock segment 114, and a pressing force is locked to the resisting ring member 2, so that the first friction member 411, the friction ring block 31 and the second friction The member 421 is tightly clamped between the resisting ring member 2 and the retaining ring 12. In the aforementioned tightened state, the resisting ring member 2 and the limit rotating shaft 1 are riveted to each other. Finally, the end cap 323 is covered by the assembly opening 326.

In this way, the mirror body 91 can be rotated with respect to the limit rotation shaft 1 along the steering joint 3, and is used for observing the passing vehicles. However, since the first friction surface 415 and the second friction surface 423 are in urgent contact with the friction ring block 31, the steering joint 3 needs to overcome a certain degree of friction to rotate relative to the limit rotation shaft 1, otherwise it will remain Positioning. Appropriate friction can prevent the embodiment from rotating due to accidental contact. That is, the embodiment can be rotated to the desired angle only when a sufficient force is deliberately applied. It should be noted that the pressing force affects the magnitude of the aforementioned friction force.

Differently, it is therefore possible to prevent a situation in which the maximum static friction of the first friction surface 415 and the second friction surface 423 needs to be overcome at the same time. It should be noted that in the embodiment, the maximum static friction force is affected by changing the surface roughness of the first friction surface 415 and the second friction surface 423, but for example, the technical means can be adopted. Not limited to this.

In addition, the first washer 412 and the second washer 422 function to uniformly distribute the pressing force to the first friction member 411 and the second friction member 421 . As a result, the steering joint 3 is better fluent when rotated relative to the limit rotation shaft 1 without being caught by uneven force.
