ストン装置。 A sphere is provided at one end of the connecting rod that connects the crankshaft and the piston, and the front surface of this sphere is brought into contact with the seating surface of the piston, while the rear surface of this sphere is caulked with a caulking part provided on the piston, thereby connecting the piston and the sphere. In the piston device, the piston is formed of a steel pipe and a seat body that is press-fitted into the steel pipe and integrally molds the seat surface and the caulked part by forging. Machine piston device.
