  "textContent": "[Technical Field] The present invention relates to a wheel deformation mechanism and a structure of a vehicular shock-absorbing device using the mechanism. [Technical Problem] In the conventional suspension device, there are problems that a vibration damping effect for an in-wheel motor vehicle is too low to alleviate an impact on the wheel and that a mounting space is required on the vehicle body side. There is a problem that since the conventional tire is poor in ability to absorb distortion of a contact patch caused by turning, the contact patch of the wheel is subjected to horizontal friction at the time of direction change. [Solution] An expansion and contraction mechanism as shown in that connects two rotors and a band-shaped tread by a movable arm is incorporated in a wheel, [Main Use of Invention] The vehicle wheel is expanded and contracted by a rotation speed difference between the two rotors so as to control the posture of the vehicle body.",
