Friction enhanced element for shaft clamping device for toy wheel hub, is thin and laminar, where shaft clamping device is provided for frictionally engaged clamp on shaft

摘要

The friction enhanced element (1) is thin and laminar, where a shaft clamping device is provided for frictionally engaged clamp on a shaft (3). A friction enhanced surface has a larger friction coefficient with the shaft than the shaft clamping device. An independent claim is included for a toy wheel hub with a shaft clamping device.
