Description

  The present invention relates to a silencer side groove, and a rattling sound that causes noise and vibration due to poor surface contact due to dimensional errors caused by manufacturing accuracy of the side groove lid of the side groove main body and the side groove lid covered by the lid hook portion. The present invention relates to a muffler-type side groove that can mute the sound and eliminate the occurrence of slippage and corner chipping.

  Conventionally, as a muffler side groove block, a convex curved surface or a convex curved surface is provided on both lower sides of the lid plate, and a concave curved surface or a concave curved surface is provided on the lid receiving portion of the side groove main body, and the lower side of the lid plate is the lid of the side groove main body. In the silencer side groove block that is supported so as to adhere to or bite into the receiving part to prevent the cover plate from rattling, the outer surface from the upper side to the lower side of the side wall is formed in a vertical plane with no irregularities, and each side of the side groove body A ridge extending in parallel with the water channel is provided facing the inner surface of the side wall, a lid receiving portion for supporting the lid plate is provided on the upper surface of the ridge, and the lower surface of the ridge is an inclined surface that extends downward. There was a thing (for example, refer to patent documents 1).
