ABSTRACT:
An electrically driven vibrating apparatus such as a dry shaver comprises a single-phase synchronous motor having a drive shaft, together with a part to be reciprocated. A cam is rotated by the motor drive shaft, and a lever is journalled about a pivot and is in contact with the part to be reciprocated. A pressure roller is mounted on the lever and is in constant contact with the cam profile. A compression spring acts on the lever to urge the pressure roller towards the cam.
