Figures 1 to 5 show an embodiment of the present invention, in which Figure 1 is a longitudinal sectional view of a piston, Figure 2 is a view taken in the direction of Figure 1, and Figure 3 is a perspective view of a piston pin. Figure 4 is a diagram showing the fitted state of the piston pin and connecting rod, Figure 5 is a longitudinal sectional view showing the state in which the connecting rod is connected to the piston via the piston pin, and Figure 6 is another embodiment of the present invention. It shows
FIG. 7 is a longitudinal sectional view showing a conventional example, showing a fitted state of a piston pin and connecting rod. In the figure, 1 is a piston, 2 is a boss, 3 is a pin hole, and 4
4a is the lower part of the piston pin 4, 4b is the upper part of the piston pin 4, 5 is the connecting rod, 6 is the pin hole, and 7 is the gap.
Claims (1)
側部分の半円の半径より小さい円弧状にピストン
ピンを形成し、該ピストンピンを一体に嵌合する
ピン孔をピストンのボスに半径方向に設け、更に
前記ピストンピンに嵌合するコンロツドのピン孔
に、該ピストンピンの頂部及び底部の接触しつつ
所要の角度回転し得る隙間を設けたことを特徴と
するエンジンのピストン構造。 A piston pin is formed in the lower part in a semicircular shape and the upper part in an arc shape whose top part is smaller than the radius of the semicircle in the lower part, and the pin hole into which the piston pin is integrally fitted is formed in the boss of the piston. A piston structure for an engine, characterized in that a gap is provided in a radial direction and further provided in a pin hole of a connecting rod that fits into the piston pin, allowing the top and bottom of the piston pin to rotate through a required angle while being in contact with each other.
