Abstract: To provide a bottom for a bed apparatus that can relieve the sensation of being pressed and that at the same time is lightweight, easy to transport and can be cleaned easily. A bottom for a bed apparatus having a back-raising mechanism, includes a flexing bottom that is arranged between a back bottom and a hip bottom and can be flexed. In a back-raising operation, the flexing bottom flexes between the back bottom and the hip bottom while sliding downward over the surface of the uprising back bottom.

Abstract: An aeration tube according to the present invention, which is configured to supply a cleaning gas for a filtration unit, includes a straight tubular aeration portion, into one end of which the cleaning gas is force-fed and which has a plurality of aeration holes, and a tubular solid content discharge portion which extends from another end of the aeration portion. In a vertical cross section including a central axis of the aeration portion, a central axis of a discharge side of the solid content discharge portion is inclined downward with respect to the central axis of the aeration portion, and an angle of inclination of the central axis of the discharge side with respect to the central axis of the aeration portion is 20° to 80°. Preferably, the aeration holes are arranged on an upper side of the aeration portion, and centers of the aeration holes coincide with the vertical cross section including the central axis of the aeration portion.
