ABSTRACT:
A VCR having a reel gear brake device is formed with a friction plane along the circumferential plane of a reel gear, and a brake member arranged to be able to swing about a hinge shaft toward the friction plane by a predetermined angle. An operational spring is installed between one end of the brake member and a brake operating member, and one end of the brake member projects to extend for forming an elastic beam. A control cam eccentrically rotated at the center of the elastic beam is closely installed for minutely controlling the braking force of the brake member since the elastic force of the elastic beam is changed in accordance with the rotated positions of the control cam. Thus, the operation of the brake member is maintained in the optimum state and manufacturing cost is lowered to enhance assembling productivity while the construction is simplified.
