ABSTRACT:
A tape tension adjusting device for use in a video cassette recorder includes a tension lever rotatably mounted on a deck to be biased toward the tape by a spring and having a tension pole coming into contact with the tape, a band holder mounted on the tension lever and having a first fixing portion which is of a cylindrical shape and a second fixing portion which is substantially a semicircle, the first fixing portion having a smaller diameter than that of the second fixing portion, and a band brake retained around the supply reel, for exerting a braking force on the supply reel. One end of the band brake is fixed to the first fixing portion of the band holder and the other thereof is fixed to the second fixing portion of the band holder, thereby controlling a rotating speed of the supply reel and adjusting tape tension.
