| Outline of Final Research Achievements |
The effect of micro-texturing on improvement of lubrication properties in reciprocating lubricated surface was investigated by various patterns such as unidirectional groove, long form dimple, cross-groove, dimple, and non-treated mirror finished surface. The conclusions are as follows ; In the case of large reciprocating stroke, "dimple pattern" is most suitable because lubricating oil in the dimple is possible to bear the normal load. On the other hand, in the case of small reciprocating stroke, "cross-grooved pattern" is most suitable because a supply of the lubricating oil from outside of contacting surfaces is possible in an acceleration effect of the initial running-in process.
