Abstract

The present invention relates to a vibration reduction device of a muffler tail-pipe for construction equipment, comprising: an engine hood provided to one side of an engine room for the protection of the peripheral parts including an engine and a muffler, and having a through hole at one side of the top surface thereof; the muffler provided to the lower portion of the engine hood in a state where the muffler is connected to one side of the engine; a tail-pipe of which one end is connected to the muffler and the other end is protruded to the outside by penetrating the through hole of the engine hood; and a plurality of elastic support parts for fixing the tail-pipe such that the tail-pipe is elastically supported by the engine hood. The present invention can maximally reduce the vibration transmitted to the tail-pipe by the elastic support means when the tail-pipe vibrates with the muffler due to the vibration of the muffler by the engine, as the tail-pipe connected to the muffler is elastically supported from the engine hood through the elastic support parts. Therefore, the present invention can solve the problem of the connection portion of the muffler and the tail-pipe being easily deformed or damaged by the concentration of the stress to the connection portion of the muffler and the tail-pipe as the tail-pipe vibrates with the muffler according to the vibration of the muffler.
