Claims

[Scope of utility model registration request]

(1) The piston head portion and the piston skirt portion are partially connected by a connecting portion around the piston pin hub to form an X-shaped piston, and at least the connecting portion and the piston force-toe portion are embedded with reinforcing fibers. A piston characterized in that it is made of fiber-reinforced metal.

(2) The reinforcing fibers in the connecting portion are oriented so as to curve smoothly and roundly around the piston pin hole and extend from around the piston pin hole toward the piston head and piston skirt. The piston according to item 1.

(3) The utility model according to claim 1, wherein the piston skirt portion is formed to have a track shape in cross section, and the fibers in the piston skirt portion are oriented in the circumferential direction of the track shape. piston.
