Abstract

Abstract Translated from Japanese (57)【要約】 【課題】低コストで、大型化することなく、エンジンに 応じてオートデコンプ装置を簡単に備えることができ、 しかも取り外しが容易で保守点検作業が簡単であるオー トデコンプ装置を備える船外機を提供する。 【解決手段】船外機102は、船舶に搭載された船外機 102にエンジン1を備え、このエンジン1のクランク 軸2に連動して回転し吸気弁27と排気弁28を開閉す るカム軸25を設け、エンジン1の始動に排気弁27を 開き圧縮圧を抜くオートデコンプ装置Dを備え、オート デコンプ装置Dに、エンジン1の始動時にクランク軸2 との連動を遮断して排気弁28を開状態として圧縮圧を 抜き、始動後にクランク軸2と連動して排気弁28を閉 じ状態として圧縮圧の抜きを中止する遠心クラッチ機構 45を備え、この遠心クラッチ機構45をエンジン1の 外側部に着脱自在に設けている。 (57) 【Abstract】 PROBLEM TO BE SOLVED: To easily provide an auto decompression device according to an engine at a low cost without increasing the size, Moreover, an outboard motor provided with an auto decompression device that is easy to remove and easy for maintenance and inspection work is provided. SOLUTION: An outboard motor 102 is equipped with an engine 1 in the outboard motor 102 mounted on a ship, and a camshaft which rotates in conjunction with a crankshaft 2 of the engine 1 to open and close an intake valve 27 and an exhaust valve 28. 25, and an auto decompression device D that opens the exhaust valve 27 and starts compression pressure when the engine 1 is started. The auto decompression device D is provided to the crankshaft 2 when the engine 1 is started. The centrifugal clutch mechanism 45 is provided to stop the compression pressure release by opening the exhaust valve 28 in the open state to release the compression pressure by interlocking with the crankshaft 2 and starting the engine in conjunction with the crankshaft 2 to close the exhaust valve 28 in the closed state after starting. The centrifugal clutch mechanism 45 is detachably provided on the outer side of the engine 1.
