<P>PROBLEM TO BE SOLVED: To provide a piston for an internal combustion engine capable of suppressing permanent deformation of skirts, achieving wear reduction and improvement of anti-seizing properties of a sliding part, reducing weight, friction and noise, and reducing oil consumption and blow-by gas. Ž<P>SOLUTION: The piston 1A for the internal combustion engine includes a head 2, a pair of first and second pin bosses 3, 4 provided in the lower part of the head 2, a first sidewall provided on the lateral side of the first pin boss 3, and a second sidewall 5 provided on the lateral side of the second pin boss 4. The skirts 7A extended downwardly from the peripheral edge part of the head 2 are partially provided on portions corresponding to end parts of the first and second sidewalls 5A, 6A on the peripheral edge part lower side of the head 2.
