A tension controller of a tape recorder maintains a constant tension in a running tape in the tape recorder. One embodiment includes a friction element for generating frictional force on one side of a tape reel disk, a tension controller for controlling the tension of the tape in which the tension controller is resiliently contacted by means of a spring in an upper face of the friction element, a slant cam formed at the edge of the contacted surface, and a tension pole formed in the upper direction on one side of a tension arm. A lifter minimizes the frictional action on the tape by being connected to a moving lever formed on the lower side of the tension controller and raising the tension during controller high-speed searching. Automatic control of the infinitesimal tension of the tape and prevention of interference in the tape during high-speed searching may be attained. The deck can be compact and the number of parts for the fabrication can be reduced to a simple structure, thereby providing many advantages in the fabrication process.
