Zusammenfassung:	To provide sealing structure achieving improvement of sealing performance for a combustion chamber.SOLUTION: Apex seals 50, 80 are held in a square first member 24b of a first piston member 24. The apex seal 50 contacts a second piston member 28 to seal a space between the first piston member 24 and the second piston member 28. The apex seal 50 has longitudinally divided structure with a main member 51 and a side member 52. The apex seal 80 contacts a housing 4 to seal a space between the first piston member 24 and the housing 4. The apex seal 80 has longitudinally divided structure with a main member 81 and a side member 82.SELECTED DRAWING: Figure 5 【課題】燃焼室のシール性能を向上できるシール構造を提供する。【解決手段】第１ピストン部材２４の角型の第１壁面部材２４ｂに、アペックスシール５０，８０が保持されている。アペックスシール５０は、第２ピストン部材２８に接触して、第１ピストン部材２４と第２ピストン部材２８との間をシールする。アペックスシール５０は、メインピース５１とサイドピース５２とを有する、長手方向に分割された構造を有している。アペックスシール８０は、ハウジング４に接触して、第１ピストン部材２４とハウジング４との間をシールする。アペックスシール８０は、メインピース８１とサイドピース８２とを有する、長手方向に分割された構造を有している。【選択図】図５
