PURPOSE: A speed drive gear for a manual transmission is provided to reduce parts and simplify assembling process by integrally forming a gear part and a flange part of the speed drive gear, and to prevent noise and breakage by restricting clearance after assembling. CONSTITUTION: A speed drive gear of a manual transmission is composed of a gear part(10) combined with a main shaft(6) to receive rotational force of the main shaft, and engaged with the speed gear; and a flange part(12) integrally extended in the end of the gear part, and connected to a propeller shaft. A fixing nut(18) is inserted to the side of the flange part, and combined with the main shaft. The gear part is spline-combined with the main shaft, and the fixing nut is assembled with the flange part. The speed drive gear is fixed in the main shaft, and the flange part is assembled with the propeller shaft by the bolt. Driving force is transmitted through the main shaft to the propeller shaft in driving the engine. Parts and expenses are reduced with integrally forming the gear part and the flange part of the speed drive gear. Noise and breakage are prevented with assembling without clearance.
