摘要： A tape cassette has a case with upper and lower halves and an open space at the front thereof. A magnetic tape housed in the case is wound around a pair of reels. A brake is slidably mounted on the inner surface of the lower half of the case to prevent the reels from being rotated. Part of a spring is attached to the brake. The spring has free ends and urges the brake in a direction. A device for positioning the spring includes a partition wall on the inner surface of the lower half of the case which partitions the open case from the inside of the case. An independent abutment member on the partition wall abuts the free ends of the spring.
