Abstract: A vibration reduction device includes: a rod rigid body supported between an engine and a vehicle body via respective elastic bodies, a resonance frequency of which is set to be lower than an engine rigid body resonance frequency; an elastic component that is provided on the rod rigid body and caused to deform by a force acting in an axial direction of the rod rigid body; an inertial mass supported by the elastic component; and an actuator that causes the inertial mass to reciprocate in the axial direction of the rod rigid body by generating a force that is proportionate to an axial direction velocity of the rod rigid body. As a result, resonance itself can be suppressed without reducing a double vibration proofing effect.
Abstract: A connecting rod shank of a connecting rod is composed of a plurality of laminated plates having a thickness so that they can be introduced through a gap provided in a partially cylindrical base body of a loop tensioner for a tightening band which encloses the connecting rod shank.
