Abstract: A gear-shifting device 50 for a manual transmission comprises a shift arm 53, which is rotatable in correspondence to the shift operation of a change-lever L, and shift pieces 41, 43 and 45, each of which shifts in correspondence to the rotation of the shift arm 53, with this shifting of the shift piece 41 achieving a gear shift. The gear-shifting device 50 further comprises a load-attenuating mechanism 90, which includes a spline groove 51b, a fitting room 91, a steel ball 92 and a coned spring 93. In the attenuating mechanism, the steel ball 92 is pushed to the spline groove 51b by the coned spring 93, allowing the shift arm 53 to rotate with respect to the shift selector shaft 51 to reduce the load acting on the change-lever L from synchro-sleeves 71, 73 and 75.
