Abstract
PURPOSE: To prevent invasion of rain or dust as well as the generation of shock sound by installing a shock absorbing member on each mutually hitting flange areas of adjacent cylinders, while allowing the flanges to project at least partially from the end surfaces.
CONSTITUTION: Flanges f0 thru f4 are provided at the ends of a plurality of cylinders C0 thru C4. Shock absorbing members 11, 18, 19 and 25 are installed in either one of the flanges hitting with each other during compression stroke, in such a way as to allow flanges to project at least partially from the end surfaces. Then, it may be achieved to absorb the shock during the compression stroke of a multistage cylinder, thereby preventing the generation of shock sound. The shock absorbing members also prevent the invasion of rain or foreign matter such as dust or grit before the sliding surfaces of the cylinders.
