「るとともに、エンジンによる推進ユニットの振動が船
体側に伝わるのを防止している。In an outboard motor, a propulsion unit is supported at both upper and lower ends of a steering shaft supported by a swivel bracket on the hull side, via an upper support means and a lower support means. -The upper support means and the lower support means have a cushioning material such as anti-vibration rubber, and transmit the propulsive force generated by the propulsion unit to the hull side.-
It also prevents vibrations from the propulsion unit caused by the engine from being transmitted to the hull.

いる。However, in the conventional propulsion unit support structure, both the upper support means and the lower support means are coupled to the casing of the propulsion unit, and the lower support means is submerged in water during navigation, causing navigation resistance. It is set at a predetermined height level with respect to the casing to prevent it from causing damage.

適正な防振性能を確保することが困難となる。Therefore, in the conventional f propulsion unit support structure, when the casing is made shorter and smaller in order to make the outboard motor smaller and lighter, the upper support means is attached to the lower support means which is set at a predetermined height level with respect to the casing. As they approach each other, the mutual supporting span between the upper and lower support means becomes shorter, and the support load exerted by the propeller propulsion force on each of the upper and lower support means increases.
-ru. Therefore, the spring constant of the cushioning materials constituting the upper and lower support means must be increased in order to suppress the displacement due to the increased support load as described above to an allowable range.
It becomes difficult to ensure proper vibration isolation performance.
