元力を助長させることができる。Sheath-shaped spring mounting portions 6 are fixed to the back surface of the back support plate 1 at upper and lower positions, respectively, and leaf springs T, T separately provided between the corresponding upper and lower spring mounting portions 6. It can be inserted and locked in a detachable manner. This leaf spring can be replaced by a straight wire spring of piano wire if desired. This invention has the above-mentioned structure, and is fixed to the body torso via the mounting band 4.5 suspended from the left and right armpit parts 2.2 and the left and right waist rest parts 3.3, as in the conventional one. However, while the conventional one was a single piece made of a semi-rigid material, as mentioned above, there is a predetermined space between the upper and lower spring mounting parts 6.6 and 6.6 on the outer surface of the back surface. By attaching elastic plate-shaped or linear leaf springs 1 and T as needed, the degree of flexibility of the back support plate 1 that is in close contact with the back can be freely selected.
, 1 is not attached to the back surface except for its top and bottom edges, so
Depending on the wearer's health condition and work content, it is possible to allow the user to freely bend the dorsi of the spine without unnecessarily fixing the back, and it can also be used to restore normal spinal flexion due to work. It can enhance power.

ある。Furthermore, the whole body is different from a conventional single-piece cylinder, except for the back surface, which is formed into left and right armpit parts 2.2 and left and right waist parts 3, 3 that surround the body torso separately and spaced apart vertically. Because of this, there is no obstacle to the wearer bending the body forward or arching the body backward. The present invention has a simple structure as described above, and the plate spring or linear spring can be installed and removed very easily, making it efficient for everyday use.
