Abstract

The present invention is intended to reduce noise or vibration occurring in an exhaust gas mixer, and provided with: a mixer main body that has a hollow part extending in an axial direction; an inner pipe part that is provided in the hollow part along the axial direction; a gas introduction part that is provided to the mixer main body, and introduces mixing target gas into a space to spiral the mixing target gas; and a gas lead-out part that is provided in the inner pipe part to lead out the mixing target gas, wherein a central axis of the inner pipe part and a central axis of the hollow part are provided in mutually different positions.
