An engine flywheel is provided to block backward power supply via structure in response to engine stop, thereby preventing damage to a DMF(Double Mass Flywheel) and minimizing the transmission of shock transmitted to a vehicle body. An engine flywheel includes main and auxiliary masses(1,3), a damper spring(5), a clutch block(9), wedge blocks(11), and clutch weights(13). The main mass is formed in the circular disc shape with a hole in the center. The auxiliary mass is coupled with the main mass concentrically to rotate with respect to each other. The damper spring elastically supports the auxiliary mass with respect to the main mass in the rotation direction between the main and auxiliary masses. The clutch block is contactlessly inserted into the inner diameter part of the auxiliary mass and concentrically coupled with the auxiliary mass, wherein a crank shaft(7) is coupled in the center of the clutch block. The wedge blocks are integrally formed into the auxiliary mass to be adjacent to the clutch block and mounted with the clutch weights rotatively. The clutch weights are held by the wedge blocks by centrifugal force when the clutch block rotates forward, but not in the opposite case.
