A piston cooling structure for an engine includes a first nozzle and a second nozzle for injecting a cooling liquid towards a back face of a piston that reciprocally move within a cylinder bore along a cylinder axis line. The first angle of inclination of an axis of the first nozzle relative to the cylinder axis line is set to be smaller than the second angle of inclination of an axis of the second nozzle relative to the cylinder axis line.
