摘要： A piston cooling apparatus includes: a main body including a communication passage communicating with an oil path formed in an internal combustion engine; a nozzle pipe portion including an oil injection port configured to inject oil having passed through the communication passage toward a piston; and a filter disposed upstream of the nozzle pipe portion on the flow passage of the oil and including a hole having a smaller diameter than the minimum diameter of the oil injection port, the oil being injected toward the piston from the oil injection port, wherein: the filter is removably mounted on the outer surface of the outer wall portion of the main body existing upstream on the oil flow passage; and the main body is mounted on the internal combustion engine in a state where at least a portion of the filter is inserted into the oil path.
