A full erasing head unit disposed on a deck chassis of a video cassette recorder includes a full erasing head, a base plate for mounting the full erasing head thereon in such a way that the full erasing head comes into contact with a traveling tape, the base member movably disposed on the deck chassis, a resilient member for exerting an elastic force on the base plate, a pin provided at the deck chassis and coming into contact with the resilient member in such a way that the resilient member biased by a tape tension is allowed to return to an initial position thereof, thereby additionally performing the role of the impedance roller.
