摘要： A magnetic tape cassette capable of highly improving workability and productivity in its manufacturing while ensuring its satisfactory function. The cassette includes a spring for constantly urging each of hub braking levers in a direction of engaging the lever with a reel hub to selectively lock the reel hub. The spring is formed so as to have a substantially straightly extending or flat shape when it is unloaded or in a free state and arranged in a casing in a manner to be constantly kept deflected by cooperation of an urging element and a support element each provided on the hub braking lever and a holding element provided on the casing and constantly abuttedly held at one end thereof on a contact element provided on the hub braking lever.
