The trolley (20) has a wheel for storage of a base part at rails and comprising bearings for indirect fastening at the base part. The wheel bearings allow a translatory relative movement between the wheel and base part in operation. The wheel bearings have a torque-proof bearing portion opposite to the base part and a spring eccentric cam rotatably movable in a circumferential direction in relation to the bearing portion in a limited periphery. The cam has an eccentric ring arranged between the bearing portion and a wheel portion.
