Abstract

A mushroom-type pin retainer for a pin having a central bore and which connects a piston and a piston rod of an internal combustion engine. The pin retainer is comprised of a mushroom head connected to a shaft. The shaft has a section of larger diameter for insertion into the bore of the pin. This section is no longer than 2 mm in an axial direction and is located remote from the mushroom head, so that the pin retainer may swing by a limited angle during mounting in the bore. This configuration makes the assembly simple to mount, even if it is manufactured by an imprecise manufacturing process such as injection molding.
