An electric oral cleaning tool having a movable oral cleaning head, comprising:

• a housing having a head section with a head cavity for accommodating a movable oral cleaning head and a neck section with a neck cavity and a handle coupling section;
• a first magnetic coupling element including at least a permanent magnet or a magnetizable element being provided in the neck section for mechanical handle drive shaft connection by magnetic interaction;
• wherein the first magnetic coupling element is mounted at a motion transmitter, the motion transmitter extending inside the neck cavity to the head cavity, the motion transmitter being arranged so as to be movable in a linear or longitudinal direction, wherein the motion transmitter is coupled with the oral cleaning head such that during operation the linear reciprocation is transmitted to the oral cleaning head, and
• wherein the motion transmitter is made as a single integral part from a plastic material, and
• wherein the first magnetic coupling element is overmolded with an injection-molded plastic material and has at least one groove filled with the injection-molded plastic material.
