The present disclosure relates to an oral hygiene device, the oral hygiene device having a longitudinal axis, a carrier element attached for driven operation, and a first end for transmitting drive force to the carrier element. A motion transmission device having a first end provided at a position that is offset from the longitudinal axis, the motion transmission device being positioned essentially on the longitudinal axis or essentially in operation. A motion transmission device having a second end disposed to be positioned on a longitudinal axis in general, wherein the motion transmission device is a first coupling component comprising a first end. Essentially having a first connecting part extending along a central axis arranged at an angle with respect to the longitudinal axis and a second connecting part comprising a second end. The first connecting component includes the first connecting component and the second connecting component. A first connecting part fixedly connected to the first connecting part of the elastic pivoting element allowing to pivot relative to each other in at least a first pivoting plane spanning the longitudinal axis and the central axis； Comprising a reinforced plastic material and made from a plastic material having a Young's modulus of at least 5000 MPa or from a metal material, and at least the first connecting part, in particular the entire elastic pivoting element, of 3000 MPa or less, optionally 1000 MPa or less, Further, it is optionally made from a plastic material having a Young's modulus of 500 MPa or less.本開示は、口腔衛生用具に関するものであり、該口腔衛生用具は、長手方向軸と、従動動作のために取り付けられるキャリア要素と、駆動力をキャリア要素に伝達するための第１の端部を有する運動伝達装置であって、第１の端部が、長手方向軸からオフセットされている位置に提供され、運動伝達装置が、本質的に長手方向軸上に位置付けられるか、又は動作中に本質的に長手方向軸上に位置付けられるように配設される第２の端部を有する、運動伝達装置と、を備え、運動伝達装置が、第１の端部を備える第１の連結部品であって、本質的に、長手方向軸に対してある角度で配設される中心軸に沿って延在する、第１の連結部品と、第２の端部を備える第２の連結部品とを有し、第１の連結部品は、第１の連結部品及び第２の連結部品が、長手方向軸及び中心軸にわたる少なくとも第１の回動平面の中で互いに対して回動できるようにする弾性回動要素の第１の接続部分と固定的に接続され、第１の連結部品が、強化プラスチック材料を含み、少な
