Claims

[Scope of utility model registration request]

A vehicle in which one end is fixed to the vehicle body and the other end is rotatably supported on the vehicle body, and a swinging arm fixed to the other end absorbs the vertical movement of the rotatably supported wheel by its torsional elasticity around its axis. A torsion tube for suspension, which includes a fluid chamber provided within the torsion tube and filled with an incompressible fluid, and one end of which is fixed to either one end or the other end of the torsion tube and extends in the axial direction within the fluid chamber. It includes an extending vane, a fixed plate that extends and is fixed in the axial direction within the fluid chamber and partitions the fluid chamber together with the vane, and an orifice passage provided in the vane or the fixed plate that communicates the partitioned fluid chamber. A torsion tube structure for vehicle suspension characterized by:
