Title: Piston pin supporting structure for internal combustion
Inventor: KOJIMA MASAMICHI
IPC: F16J1/18
Filed: 1995-02-17
Abstract: PURPOSE: To improve an assembling property of a piston pin and the like by forming engaging grooves engaging with a circlip in the piston pin and forming a positioning groove engaged with the circlip on the inner circumference face of a piston pin hole. CONSTITUTION: Recessed end faces 22 opposed to each other parallelly are formed in one end of a piston pin 2. In each of the recessed end faces 22, an engaging groove 21 with which a circlip 5 is engaged is formed. A positioning groove 12 with which the circlip 5 is engaged is formed on the inner circumference face of a piston pin hole 11. When the piston pin 2 is assembled in the piston 1, the circlip 5 is previously engaged with the respective engaging grooves 21, and then, the circlip 5 is warped so as to be inserted into the piston pin hole 11 while being engaged with the engaging grooves 21. In this process, the circlip 5 is pressed to a pair of the opposed engaging grooves 21 when the circlip 5 is warped so as to be inserted into the piston pin hole 11, so that engagement with the respective engaging grooves 21 is not released.
