Abstract:
A piston cooling device includes a main body which includes a communication path communicating with an oil passage provided in the internal combustion engine, a nozzle pipe portion which includes an oil injection port for injecting an oil passing through the communication path, toward the piston, and a filter which is provided at an upstream side of the nozzle pipe portion in an oil flow path to filter the oil. The main body includes a cylindrical portion inserted into the oil passage. The filter has a bottomed cylindrical shape in which a filter side surface stands from a filter bottom surface, and is held inside the cylindrical portion. Filter holes are formed in the filter bottom surface and the filter side surface. The filter is disposed such that the filter bottom surface protrudes further upstream side in the oil flow path than a tip end of the cylindrical portion.

Claim (Index 4):
The piston cooling device according to  claim 3 ,\n wherein the oil passage includes;\n an insertion hole into which the main body is inserted; and \n an upstream hole which is connected to the insertion hole through a step portion and has a smaller diameter than the insertion hole, and \n wherein the filter bottom surface of the filter is disposed along the step portion.
