Claims

[Scope of utility model registration request]

The bracket holding the pinch roller facing the capstan is rotatably inserted into the support shaft fixed to the support base without a retaining mechanism, and the bracket is inserted into the support shaft torsionally. One of the arms extending from both ends of the coil spring is pressed against the hook on the support base with elastic force, and the other arm applies elastic force against the bracket in a direction to press the pinch roller toward the capstan. At least one of the hooking part on the support base and the bracket is formed with a fitting groove in which the arm of the torsion coil spring is fitted without shifting in the axial direction of the support shaft. Pinch roller mechanism of tape player.
