Claims

[Scope of utility model registration request]

An input shaft with one end connected to the engine in an intermittent manner and a drive gear provided at the other end, and a plurality of transmission gears corresponding to gears in the same rotational direction and gears in the opposite rotational direction of the input shaft are rotatably connected to the engine. A main shaft provided, a plurality of sub-transmission gears positioned substantially parallel to the main shaft and meshing with the transmission gear are provided so as to rotate together, and a driven gear meshing with the driving gear is provided, and the input shaft is provided with a driven gear meshing with the drive gear. a subshaft that rotates integrally with the transmission; and an operation mechanism that connects the main shaft to the input shaft or one of the transmission gears so as to rotate integrally with the input shaft or one of the transmission gears according to the operation position of the operation lever. An electromagnetic brake capable of stopping the rotation of the subshaft is provided, and means is provided for detecting that the operating lever is in a position where it is operated only to shift gears in the reverse rotation direction, and when an output signal of the means is generated, the electromagnetic brake is activated. A gear noise prevention device for a transmission, characterized in that the rotation of the subshaft is stopped by:
