     A speed-regulating support frame for music box is an integral structure of spring casing and speed-regulating support frame. A through hole is made on the top ofthe integral structure. A movable plate of bearing, which has L-shape structure and can be linked to or detached from the through hole at any time, can be locked in the flat hole on peripheral wall of spring casing by its elastic pins. After said movable plate is positioned on the through hole, the level of its top is lower than the top level of said integral structure. Its advantage is that its speed-regulating axle is not damaged easily when the music box is impacted.
