To provide a drain pipe device capable of saving an installation space and surely absorbing a displacement by the amplitude of earthquake.
A drain header 17 is fitted to a base isolation layer 2. A drain pipe 24 is communicably connected to the outlet 23 of the drain header 17. The drain pipe 24 and a drain pipe 46 fixed to a base 3 are communicably connected to each other through a flexible bellows pipe 30 with an elbow 27 and an elbow 45. A slidably moving support slider block 43 having the projected part of an abrasive reducing means projected from the rear surface thereof is fitted generally to the intermediate part of the bellows pipe 30, and the support slider block 43 is placed on the base 3. By this, the displacement between the drain pipe 24 and the drain pipe 46 by the amplitude caused at the time of earthquake can be surely absorbed by the displacement of the bellows pipe 30 and the sliding of the support slider block 43. A drain pipe 15 from drain equipment is communicably connected to the inlet 17a of the drain header 17.
