Abstract: PURPOSE: A rattle-noise reducing apparatus of a manual transmission is provided to reduce rattling noise generated by change of engine torque and to improve productivity with a simple structure. CONSTITUTION: A rattle-noise reducing apparatus of a manual transmission includes a drive shaft(22), a drive gear(24), a driven gear(28), a power transmitting gear(30) and an elastic connecting bar(32). The drive shaft is rotated by receiving power of an engine. The drive gear is rotated with the drive shaft by being formed integrally to a tip of the drive shaft. The driven gear is geared to the drive gear and splined to a counter shaft(26) with specific clearance to be moved slightly toward a circumferential direction. The power transmitting gear is fixed to the counter shaft. The elastic connecting bar is fixed to the power transmitting gear on the one end and inserted to a hole(27) of the driven gear on the other end to transmit rotating force of the driven gear to the power transmitting gear. The elastic connecting bar reduces relative rotating speed difference in the driven gear and the counter shaft. Therein, rattling noise generated from a gear groove of the driven gear and splined gear teeth of the counter shaft is reduced.
