PROBLEM TO BE SOLVED: To remove foreign matter adhering to a slide surface, and maintain a floating effect of floating one member to the other member, in order to solve a problem in a case of using a friction reduction method with floating to a slide part.SOLUTION: An engine 1 includes a crank shaft 10 and a connecting rod 20 relatively moving to the crank shaft 10, and has a low friction layer 40 on the slide surface of at least one member of the crank shaft 10 and the connecting rod 20, the low friction layer subjected to friction reduction processing of floating any one member to the other member when the relative speed of both member 10, 20 is a predetermined relative speed or more. The engine includes deposit removal means of removing foreign matter adhering to the slide surface.SELECTED DRAWING: Figure 4 |
