The invention relates to the field of safety products, in particular to a speed limiter.In order to solve defects in the prior art, the invention provides the speed limiter which is provided with a simple structure and used conveniently and reliably. The speed limiter comprises a speed-limiting brake outer ring, a speed-limiting brake core, a speed-limiting brake needle and a reset structure. A driven structure and a stop structure are arranged on the speed-limiting brake needle. A limiting structure is arranged on the speed-limiting brake core. The driven structure is capable of rotating with the speed-limiting brake core. The stop structure is used for limiting rotation of the brake core. The reset structure, the speed-limiting brake needle and the speed-limiting brake outer ring are connected. The reset structure enables the speed-limiting brake needle to restore at an original position. The speed-limiting brake core can be rotatably arranged in the middle of the speed-limiting brake outer ring. The speed-limiting brake needle can be rotatably arranged onto the speed-limiting brake outer ring. A rotary shaft and the speed-limiting brake core rotate together. During rotation, the speed-limiting brake needle is driven to rotate. In case of excessively high rotary speed, the speed-limiting brake needle may get the speed-limiting brake core stuck when too late to restore. Therefore, the speed limiter has a simple structure and high reliability.
