とするエンジンオーバラン防止装置。 A sleeve is provided on the outer periphery of a hub that rotates integrally with the main shaft of the transmission, and engages with each gear stage by means of a fork, and an outer circumferential groove is formed at the front and rear of the hub, and a groove is formed in the sleeve in correspondence with the outer circumferential groove. Inner circumferential grooves are formed, and day tents are inserted into each of the outer circumferential grooves, which are constantly biased toward the center of rotation by springs and which reverse the springs with a centrifugal force greater than the allowable rotation speed of each gear stage. An engine overrun prevention device characterized by having a tapered tip that is high on the outside and low on the inside.
