There is a so-called sanding having a structure in which a member for increasing a frictional force such as a paper file is interposed therebetween. In this type of upper limb function recovery training device, a trainee sits on a chair or faces an inclined member while standing upright, and moves the movable member in the vertical direction or the like along the upper surface of the inclined member while gripping the movable member. By doing so, training is performed to recover the flexion function of the upper limb, increase the range of motion of raising the shoulder, and the like.

[0003]

However, the above-mentioned conventional upper limb function recovery training apparatus has a structure in which the training is performed while moving the movable member against the frictional force generated between the movable member and the inclined member. Therefore, when the inclination angle of the inclined member changes, the drag applied from the movable element to the inclined member changes, and eventually, the frictional force generated between the movable element and the inclined member changes. In addition, there is an inconvenience that the load required to move the moving element changes, such that the friction force changes depending on the frequency of use of the member provided between the inclined member and the moving element that increases the frictional force.

The present invention has been made in view of the above circumstances, and has as its object the load required to move the movable member even when the inclination angle of the inclined member changes or during retraining. The purpose of the present invention is to provide an upper limb function recovery training device that can always maintain a constant value.

A tilt angle setting portion provided between the gantry and the tilt member and capable of setting the angle of the tilt member to a free value; and sliding the tilt member from the front to the back of the tilt member or vice versa. In an upper limb function recovery training device including a movable element freely provided and gripped by a trainee , one end of a flexible elongated member is connected to the movable element ,
The other end of the flexible elongated member is an idle provided on the shaft.
After being wound on the sprocket, it is connected to the load applying means.
It is characterized by having. The invention according to claim 2 is characterized in that the load applying means is a weight. Claim 3
In the invention described above, the weight is divided into a plurality of parts, and an arbitrary number of the elements are suspended from the other end of the flexible elongate member. The invention according to claim 4 is characterized in that the flexible elongate member is provided with a winding portion for absorbing slack of the flexible elongate member. Claim 5
The invention described in the above description is characterized in that a display device for displaying a training time when the moving element is moved is provided.

[0006]
