Vehicle wheel`s rim pressing device, has coupling unit formed by rubbing end between peripheral surfaces of retaining units and one peripheral surface at base plate coaxial to central recess and base plate

摘要

The device has a base plate (2) with a central recess (4), and multiple retaining units (6, 8, 10) rotatable around a swivel, whose rotation axes are aligned perpendicular to the base plate. A coupling unit couples rotation of the retaining units and is formed by a rubbing end between peripheral surfaces (24, 28) of the retaining units and the peripheral surface (28) at the base plate coaxial to the central recess and the base plate.
