    Abstract: The present invention addresses the problem of performing cleaning of a damper product and removal of a cleaning solution in a short time. Provided is a torsional-vibration-reducing-device manufacturing method including: a press step (S1) for molding an input rotating member and an output rotating member through punching press machining and bending press machining performed on plate materials; a heat treatment step (S4) for performing heat treatment on the molded input rotating member and the molded output rotating member; and a damper assembly step (S7) for assembling a damper product that includes, as components, the input rotating member and the output rotating member on which heat treatment has been performed, and a coil spring. The press step (S1) includes drilling processing for forming a hole opened in an outer-diameter direction with respect to the center line of rotation, at a position of at least one rotating member of the input rotating member and the output rotating member, the position serving as a spring holding section for holding the coil spring. The method includes, after the damper assembly step (S7), a cleaning step (S8) for cleaning the damper product with a cleaning solution and a cleaning-solution removing step (S9) for removing the cleaning solution remaining after the cleaning.

    Abstract: An electric powertrain (98) for an automotive road vehicle (300) is provided. The powertrain (98) comprises: a torque converter (100) having a rear end (102), a front end (104), and an output shaft (106) exiting the torque converter (100) at the rear end (102) and the front end (104), wherein, the torque converter (100) is configured to receive an input torque at the rear (102) end and to deliver an output torque with the output shaft (106). The powertrain (98) further has an electric motor (108) with a motor shaft (110) operationally connected to the rear end (102) of the torque converter (100).
