Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a closed deck type cylinder block, and the closed deck type cylinder block having excellent quality and durability.  <P>SOLUTION: The closed deck type cylinder block 1 is manufactured by press-fitting a bridge material 5 with the surface of a bridge base material 7 covered with a soft covering material 8, into the upper end part of a water jacket 4 of an open deck type cylinder block 2, and welding a joint part between the open deck type cylinder block 2 and the bridge material 5 by electronic beams 9. In press-fitting, the covering material is plastically deformed in an easy manner to ease press-fitting resistance and to reduce residual stress generated to the cylinder block 1 side. Further, since the joint part is welded by electronic beam welding, welding can be performed over the whole press-fitting region, and since stress in a reverse direction to the time of press-fitting the bridge material 5 is generated to the cylinder block 1 by melting/solidification shrinkage due to welding, residual stress is dissolved.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
