Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain desired combustion performance while suppressing oil degradation due to spillover of fuel from a piston cavity.SOLUTION: A fuel injection nozzle 22 is mounted by slidably fitting and inserting a nozzle housing 22b closer to an injection hole 22a into a nozzle insertion hole 31a formed in a cylinder head 31, while fixed and supported by fitting and inserting a nozzle housing 22c in a head side of the fuel injection nozzle 22 into a supporting member 32. Further, a top wall of the supporting member 32 is engaged with a cam 34 fixed to a rotation shaft 33 that synchronously rotates with engine rotation, and a return spring 35 is mounted as forced into a compressed state between a bottom of the supporting member 32 and an upper surface of the cylinder head 31. The profile of the cam 34 is set to axially reciprocally move the fuel injection nozzle 22 during an injection period of the fuel from the injection fuel nozzle 22.
