A drive plate (E) for an automotive vehicle for transmitting a torque from a crankshaft (6) to a torque converter (7), while absorbing a thrust load applied from the torque converter to the crankshaft is formed with: a central mount portion (11) for mounting a crankshaft; an outer gear (20) formed in an outermost circumference of the drive plate; a plurality of weight reducing holes (30) formed between the central mount portion and the outer gear at regular angular intervals; and a plurality of the outer mount portions (12) for mounting a torque converter (7) formed near an outer circumference of the drive plate at regular angular intervals. In particular, the outer mount portions (12) are formed in such a way as to project radially inward from the outer gear (20) into the weight reducing holes (30), respectively. Since the virtual bending radius (deformation length L) of the drive plate can be increased, the bending angle (DA1) can be reduced when a thrust load is applied from the torque converter to the drive plate, so that it is possible to reduce a bending stress concentrated at the central mount portion (11) as small as possible, for prevention of the drive plate from being damaged.
