PURPOSE:To prevent a blow-by phenomenon from occurring, by installing such a device that always presses a piston to a cylinder with a ring adjusting mouth part. CONSTITUTION:As a device pressing a piston to a cylinder with a ring adjusting mouth part, a slit 7 is cut in a piston skirt, making it take a spring action, while a cylinder wall 1 is pressed by a projected part 8 having the sping action, and a cylinder 1 and a piston 2 are made to be joined together enough with a ring adjusting mouth part at the opposite side. With this constitution, a blow-by phenomenon is preventable from occurring. |
