FIG. 3 is an exploded perspective view of the lower unit shown in FIG. 1, and FIG. 3 is an enlarged vertical cross-sectional view of a main part of the spigot joint between the internal combustion engine with outboard motor shown in FIG. 1 and the lower unit attached to the lower part thereof.
Claims (1)
ユニットのドライブシャフトとの芯出し用のインロー合
せ部の径を、該内燃機関の下方側のクランクシャフト支
持端部佳設けられるオイルシール挿入部の径より大きく
形成すると共に、該インロー合せ部より該オイルシール
挿入部に至る部分をテーパ状に形成したことを特徴とす
る船外機用内燃機関。The diameter of the spigot joint for centering the crankshaft of an internal combustion engine for an outboard motor and the drive shaft of its lower unit is determined by the oil seal insertion part provided at the lower crankshaft support end of the internal combustion engine. What is claimed is: 1. An internal combustion engine for an outboard motor, characterized in that the diameter of the engine is larger than that of the oil seal inserting portion, and a portion extending from the spigot fitting portion to the oil seal insertion portion is tapered.
