Claims

[Scope of utility model registration request]

In a band brake that obtains braking force by pressing a soft lining against the flange of the brake drum via a steel band, the front half of the input side of the lining surface in contact with the band has multiple recesses throughout the day. A band brake squeal prevention device characterized in that the band brake is provided so that it does not touch the outer edge of the lining.
