ABSTRACT:
An approximate straight-line mechanism that is connected to the connecting portion connecting the piston and the connecting rod regulates the movement of the connecting portion such that it moves in an approximately straight line along the axial center line of the cylinder. In one aspect, the engaging ends of multiple nearly-straight links, as well as the engaging end of the nearly-straight link that engages with the connecting portion connecting the piston and the connecting rod, constitute a single-side-support construction that enables the nearly-straight links to be rotatably connected while engaging from a prescribed direction.
