Summary:PURPOSE: A high efficiency piston is provided to prevent abrasion in a piston pin when the piston moves up and down by forming a plurality of uneven parts. CONSTITUTION: A high efficiency piston is installed to move a piston(110) up and down in a cylinder. A piston pin(122) connected with a connecting rod(120) is installed in a pin hole formed in a cut part of the piston. A width(W2) of a boss comprising the pin hole is narrow, and a length of the piston pin is correspondently formed to the width of the boss. A plurality of first concave grooves is formed on an inner circumference of the pin hole. A plurality of second concave grooves is formed on an outer circumference of the piston pin. A cut hole vertically connected to the cut part(116) is formed on a lower outer circumference of the boss.
