The invention relates to a toothbrush (10), the brushneck (12) of which, connected to an exchangeable brushhead, is deflectably held, in a reversible, resilient manner, on a hollow handle (14) by a swivel joint (18) surrounded by a sealing element (16). The brushneck (12) is provided at its coupling end (20) facing the handle (14) with an articulated head (22). The handle exhibits at its coupling end (24) facing the brushneck 912) an articulated fork (26), between whose fork legs 928,30) an articulated head 922) of the brushneck (12) is fitted-in and connected by a swivel axle (32). The sealing element (16) consists of a pressure- elastic material. The articulated fork (26) is itself of tension-elastic configuration, so that the sealing element (16) is held by the articulated fork (26) under elastic pre- tension between the mutually opposite coupling ends (20,24) of the handle (14) and of the brushneck (12). The toothbrush can be economically manufactured using a least possible number of signal parts and enables a deflection movement, which is elastically damped by the sealing element and by the elastically configured articulated fork, which deflection movement is limited by the articulated head. |
