PURPOSE: A power transmitting motor coupling device is provided to transmit the power of a motor by preventing and reducing the knocking noise due to mechanical impact load or rattle generated in a speed reducer side by absorbing external impact load by using couplers transmitting motor power.;CONSTITUTION: A power transmitting motor coupling device(1) comprises first and second couplers(10, 20) composing a pair and a flexible roller(30). The first and second couplers are coupled with each other and made of elastic materials. The flexible roller is located between the first and second couplers transmits to the second coupler side from the first coupler side or reversely.;COPYRIGHT KIPO 2012
