A rotary sleeve is rotatably arranged on the fixed cylinder via an axis, and the rotary cylinder is fixed to the rotary sleeve, and a ring-shaped rotor magnet facing each other is provided between the fixed cylinder and the rotary cylinder. In a VTR cylinder unit in which a motor mechanism consisting of a magnet and a stator coil is interposed, the yoke holding the rotor magnet is provided with a fixing part located outside the inner diameter of the rotor magnet. A VTR characterized in that the fixing part is fixed to a rotating sleeve or a rotating cylinder, and a hollow disc-shaped rotary transformer is disposed using the space inside the inner diameter part of the rotor magnet. cylinder unit.
