ータリトランス。A rotor magnetic body disposed on the upper cylinder side forming the upper part of the cylinder unit around which the magnetic tape is wound and rotatable integrally with the upper cylinder, a rotor coil attached to the rotor magnetic body, and the cylinder. In a rotary transformer for a video tape recorder, which includes a stator magnetic body disposed on the lower cylinder side that forms the lower part of the unit, and a stator coil attached to this stator magnetic body, the rotor magnetic body and the stator magnetic body are mutually connected. A convex portion having a trapezoidal cross section is formed on one of the surface portions facing the rotor, a concave portion having a cross section corresponding to the convex portion is formed on the other surface portion, and the convex portion or the concave portion on the rotor magnetic body side is formed with a convex portion having a trapezoidal cross section. A rotary transformer for a video tape recorder, characterized in that a rotor coil is disposed in a concave portion or a convex portion on the stator magnetic body side.
