Abstract: A reel brake device for use in a video cassette recorder comprises a magnetic rubber set in order to ensure a speedy action of a brake lever and to reinforce the braking force. The magnetic rubber set consists of a ring-shaped magnetic rubber mounted around a brake drum of a reel table and a magnetic rubber brake block attached to the brake lever. The magnetic rubber brake block has an opposite magnetic pole to the ring-shaped magnetic rubber and an arc-profiled abutting surface for engaging with the ring-shaped magnetic rubber.
