PROBLEM TO BE SOLVED: To provide a bed having antibacterial properties and gas permeability and including a bottom part to be easily cleaned.SOLUTION: A bottom part on which a mattress is mounted, includes cylindrical pipe members in an inner peripheral side of a framework, the four sides of which are framed by vertical frame materials extending in the bed longitudinal direction and horizontal frame materials extending in the bed lateral direction. The plurality of pipe members, both ends of which are erected on the longitudinal frame member so as to be rotatable about an axis and slidable in the bed longitudinal direction, are disposed parallel in the bed longitudinal direction. At least the external surfaces of the pipe members are formed of tin.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】 抗菌性と通気性を備え、かつ、洗浄のしやすいボトム部を備えるベッドを提供することを目的とする。【解決手段】 マットレスを載置するボトム部が、ベッド長手方向に伸びる縦枠材とベッド短手方向に伸びる横枠材とで四方を枠組みした内周側に、円筒状のパイプ部材を備え、前記パイプ部材は、軸線まわりに回転可能かつベッド長手方向に摺動可能に両端部を前記縦枠材に架設して、ベッド長手方向に並列して複数配置してあり、パイプ部材の少なくとも外表面は錫で形成されている。【選択図】 図2
