動が低減されるという効果を奏する。 Therefore, according to the above embodiment, for example, when the pistons 11 and 12 reach the top dead center, vibrations are generated by the reciprocating masses in the directions of arrows F 1 , F 2 , F 3 , and F 4 as shown in FIG. A force is generated, and as a resultant force, a yawing moment in the direction of arrow M1 (clockwise in Fig. 3) is generated, but the first eccentric mass 10, 10'
The unimpinged masses of the second eccentric masses 15 and 15' generate an excitation canceling force in the opposite direction to the excitation force in the direction of arrow F5 , and ) is generated to eliminate the yawing moment, which has the effect of reducing the vibration of the engine body that causes the engine body to swing in the left-right direction.
