Abstract
A spherical coupling structure for a piston and a connecting rod, wherein a protrusion provided to the reverse side of a crown of a piston and a holding member for holding a small end are slidably fitted onto a small end, and a holding/fastening part for holding the protrusion and the holding member is screwed in. The piston is composed of an upper piston that includes the protrusion and a lower piston that includes the holding/fastening part. The masses of the upper piston and lower piston are distributed so as to substantially match each other.
