用ピストン。The piston is composed of a piston body, a piston pin that is inserted into the piston body, and a connecting rod that has a small end bearing through which the piston pin is rotatably inserted and has an oil filler port through the top of the piston body. An oil passage consisting of an annular passage and branch passages branching in the radial direction from the annular passage is installed in the upper part of the main body, and the annular passage has an oil supply port that receives an oil jet and discharges internal lubricating oil. A piston for an internal combustion engine, characterized in that the branch passage is further provided with an oil drop hole that opens directly above the oil filler port of the small end bearing of the funnel rod.
