PROBLEM TO BE SOLVED: To provide a crank chamber compression type internal combustion engine that does not sucks air even if a fuel level is largely inclined at the abrupt braking or abrupt turning of a vehicle, or during ascending or descending a slope. SOLUTION: A crank chamber compression type internal combustion engine includes a lubricating oil reservoir chamber 38 provided outside a crank chamber 2a, and at a lower side from a cylinder head 4, an oil supply passage 39 for making the lubricating oil reservoir chamber 38 communicate with a lubricated part of a valve gear 15, and a lubricating oil pump 40 provided at the oil supply passage 39 for supplying lubricating oil in the lubricating oil reservoir chamber 38 to the lubricated part. An fuel suction port 39a of the oil supply passage 39 is located at a lower level than a fuel level S' in the lubricating oil reservoir chamber 38 when it is in a maximum inclination state.
