Here, lubricating oil is placed in the lubricating member 31, and the frictional resistance of the slide frame body 3 when sliding on the Y-direction translation slide table 2 is made smaller by the lubricating oil.

Preferably, the positioning assembly comprises a three-section positioning surface 32 and a positioning pin 33, the three-section positioning surface 32 and the positioning pin 33 are both arranged on the same surface of the floating tire membrane 4, and the three-section positioning surface 32 and the positioning pin 33 are both matched with the vehicle body. The three-section type positioning surface 32 is distributed in an arc shape, is divided into three sections which are not on the same plane, and is provided with the positioning pin 33, so that the floating tire membrane 4 can be accurately positioned on the vehicle body.

Preferably, the floating tire membrane 4 is further provided with a buffer member 34, and the buffer member 34 is provided on the same side as the three-stage positioning surface 32. The cushion member 34 is an airbag for preventing the floating tire 4 from directly colliding with the vehicle body.
