The invention relates to motor vehicle power systems and provides a vibration reduction device used for an internal combustion engine. The vibration reduction device used for the internal combustion engine aims at solving the problem that an existing vibration reduction device of the engine can not effectively restrain vibration of the engine. The vibration reduction device comprises a first sliding rail, a second sliding rail, a third sliding rail, a fourth sliding rail, a first sliding block, a second sliding block, a third sliding block, a fourth sliding block, elastic components, a first connection rod, a second connection rod, a third connection rod and a fourth connection rod, wherein the first sliding rail, the second sliding rail, the third sliding rail and the fourth sliding rail are fixed on a vehicle frame; the first sliding block, the second sliding block, the third sliding block, the fourth sliding block and the elastic components are arranged in the sliding rails respectively; the first connection rod, the second connection rod, the third connection rod and the fourth connection rod connect the sliding blocks with the engine. By the adoption of the structure, vibration of the engine in the vertical direction is converted to horizontal sliding of the sliding blocks along the sliding rails, the horizontal sliding is greatly attenuated by the elastic components on the two sides of the sliding rails, and therefore transmission of vibration of the engine to the vehicle frame and a passenger cabin is effectively restrained, and the NVH characteristic of motor vehicles is improved.
