The longitudinal member 50 ′ regulates the angle formed between the bed main body 10 and the backrest portion 20 so as not to widen.

従って、この実施例の背もたれ付き簡易ベッドＢによれば、ベッド本体１０と背もたれ部２０との接続部位１００’を、接続部のための新たな部材を付加しないで、シート状部材の表面側を残して切断されて折り曲げ自在にできるというシート状部材の構造特性を利用して形成することができ、しかも、長手状部材５０’は、背もたれ部２０にかかる荷重の一部を分担するため、構造的に強い背もたれ付き簡易ベッドＢとなり、また、構造的に強い分、背もたれ部２０の強度を低下させた安価なシート状部材を使用することもでき、更に、背もたれ付き簡易ベッドＢであるため、横臥できる他に背中を背もたれ部に当接させてリラックスすることもできる。 Therefore, according to the simple bed B with the backrest of this embodiment, the connection portion 100 ′ between the bed main body 10 and the backrest portion 20 can be attached to the surface side of the sheet-like member without adding a new member for the connection portion. Since it can be formed by utilizing the structural characteristics of the sheet-like member that can be cut and bendable, and the longitudinal member 50 'shares a part of the load applied to the backrest portion 20, Because it is a simple bed B with a strong backrest, and because it is structurally strong, an inexpensive sheet-like member with reduced strength of the backrest portion 20 can be used, and furthermore, because it is a simple bed B with a backrest, Besides lying down, you can relax with your back in contact with the backrest.
