An assembly-type motorized bed is provided which simplifies assembly work and stabilizes the structure. An upper body support mechanism (20), a lower body support mechanism (30) and a buttocks support mechanism (40) are provided. The upper body support mechanism has an upper body side frame 22, a backrest 23 and an upper actuator 24. The backrest is rotatably connected to the upper body side frame, the upper actuator is connected to the upper body side frame at one end, and the other end is connected to the backrest. The lower body support mechanism has a lower body side frame 32, a thigh support member 33, a lower leg support member 34 and a lower actuator 35. The thigh support member is rotatably connected to the lower body side frame, the lower thigh support member is rotatably connected to the thigh support member, the lower actuator is connected to the lower body side frame at one end, and the other end is connected to the thigh support member . The buttocks support mechanism has two intermediate portion side frames 41 and a buttocks support member 50. The two intermediate portion side frames have a front end portion 42 detachably connected to the upper body side frame, and a rear end portion 43 detachably connected to the lower body side frame. [Selected figure] Figure 2【課題】組立作業を簡単化し、構造を安定させる組立式電動ベッドを提供する。【解決手段】上半身支持機構２０、下半身支持機構３０および臀部支持機構４０を備える。上半身支持機構は上半身側フレーム２２、背もたれ２３および上方アクチュエータ２４を有する。背もたれは上半身側フレームに回転可能に接続され、上方アクチュエータは一端が上半身側フレームに接続され、他端が背もたれに接続される。下半身支持機構は下半身側フレーム３２、大腿支持部材３３、下腿支持部材３４および下方アクチュエータ３５を有する。大腿支持部材は下半身側フレームに回転可能に接続され、下腿支持部材は大腿支持部材に回転可能に接続され、下方アクチュエータは一端が下半身側フレームに接続され、他端が大腿支持部材に接続される。臀部支持機構は二つの中間部位側フレーム４１および臀部支持部材５０を有する。二つの中間部位側フレームは前端部４２が上半身側フレームに着脱可能に連結され、後端部４３が下半身側フレームに着脱可能に連結される。【選択図】図２
