However, since the conventional armchair with armrest supports the armrest body on the backrest body in a cantilevered manner, the length from the mounting portion to the tip of the armrest body is small. When the armrest is long and a large load is applied to the tip of the armrest, the position where the load is applied and the position of the mounting portion are apart from each other, so that the moment due to the load applied to the armrest is large, and the mounting is increased accordingly. There has been a problem that the burden on the part is increased and the armrest body is easily broken.

There is also known a structure in which a reinforcing stay is provided on the cantilevered armrest to reinforce, but there is a problem that the structure becomes complicated.

Moreover, in any case, since the armrest body is provided on the side portion of the backrest body and is located on the side portion of the backrest body even when it is not used, the widthwise dimension is a pair with the widthwise dimension of the backrest body. There is also a problem that the armrest body has a length obtained by adding the dimension in the width direction, which makes the armrest body bulky during transportation and storage.

Accordingly, an object of the present invention is to provide an armchair with armrests which is hard to break and which can be stored without wasting space during transportation and storage.
