Abstract:
The purpose of the present invention is to provide a speed reduction mechanism and a flame arrester provided with a speed reduction mechanism that are aimed at both ensuring desired flame-extinguishing performance and achieving reduced pressure loss (ensuring flow rate). A speed reduction mechanism (4): is provided on at least one side, in the axial direction of a pipe (2), of a flame arrester (3), which is provided in the pipe (2), through which inflammable fluid flows, to extinguish a flame propagating in the pipe (2); serves to reduce the speed of the flame propagating in the pipe (2); has a plurality of members; and is configured to have a tubular shape so as to be continuous in the axial direction of the pipe (2); an inner surface 40 of each member having at least one non-parallel plane (5B), (5C), which is not parallel with the axis, and the plurality of non-parallel planes being arranged side-by-side in the axial direction.
