PURPOSE: Assembling structure of a clutch hub for a synchronizer in a manual transmission is provided to improve the durability and operate the synchronizer actively by preventing wear of a spline of the clutch hub or a spline groove of an input shaft with forming the taper spline end of the clutch hub. CONSTITUTION: A spline is formed in the outer periphery of an input shaft(52) of a transmission, and a spline is formed in the inner periphery of a clutch hub(54) corresponding to the spline of the input shaft. The clutch hub is pressed and fitted to the input shaft of the transmission, and the end of the spline of the clutch hub is tapered at an angle of 1-10 degrees. The length of the taper end of the spline is 1-10 mm. Spline grooves(52a) are formed circumferentially in the outer periphery of the input shaft, and splines(54b) are formed circumferentially in the inner periphery of the clutch hub. Wear is prevented by inserting the spline end of the clutch hub to the spline groove of the input shaft.
