When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0036] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] With the continuous development of automobile technology, more and more models are equipped with rear-wheel steering devices to meet market demand. In the rear-wheel steering device, a sensor component is required. Its structure is that the body of the sensor 32 is made with a slide groove, and the sensing slider of the sensor 32 is assembled in the slide groove. When working, the sensing slider of the sensor 32 slides linearly in the slide groove, so that the sensing circuit of the sensor 32 obtains the position of the slider, thereby obtaining the linear displacement. In the prior art, since the ball head limit column of the sensor 32 needs to leave a hole to place the screw-in tool, the sensor sheet of the sensor 32 cannot be embedded.
