| Zusammenfassung: | The invention concerns a brush part (13), which can be placed upon a shaft (2) of a handpiece (1) of an electric toothbrush and is designed so that it can be detached therefrom. Said brush part comprises a bristle area, a brush shank (12) and an attachment part (11) situated inside the brush shank (12). This attachment part (11) has a first spring element (35) and a second spring element (30) that act upon the shaft (2) when the brush part (13) is placed upon the shaft (2). This results in a play-free connection between the brush part and the shaft that enables the transmission of even high vibration frequencies. |
