ABSTRACT:
A joining structure of an automotive vehicle power plant including a transmission and a torque converter. The housing of the transmission is integrally formed with a generally annular flange which is joined with a generally annular flange of the casing of the torque converter by fastening bolts so that the joining surfaces of the transmission housing and the torque converter casing are in tight contact with each other. Each fastening bolt is disposed through the bolt holes which are respectively formed in the flanges of the transmission housing and the torque converter casing. A plurality of depressions are formed at the joining surface of the transmission housing flange in such a manner that each bolt hole merges in the depression, so that projected and depressed parts are formed in the joining surface. The projected part is in contact with the joining surface of the torque converter casing flange. When the bolts are fastened, the fastening force is initially applied to the projected parts and thereafter gradually applied to the depressed parts, thereby being uniformly distributed over the whole joining surface of the transmission housing flange.
