  The present invention relates to an improved grip strength assisting device that can reinforce an arm or the like by using a rehabilitation device that requires grip strength even in a state in which a finger does not move due to a disease such as cerebral infarction and there is almost no grip strength.

When physical function decreases due to cerebral infarction or the like, recovery training is performed at an early stage, which is the basis for early recovery. Even if it is difficult to walk, training of hands and arms can be performed even while sleeping or sitting, so it is desirable to start early.
Originally, it is only necessary to train the fingertips and arms at the same time, but many arm recovery exercises are performed by grasping an instrument.
In order to do so, arm movement recovery training is impossible unless the fingertips are restored and the gripping motion of the device is enabled, and arm rehabilitation tends to be delayed, which causes the delay in recovery of physical functions. It was also.
There are various devices for finger recovery training, but there was no assistive device that could assist in gripping with poor grip and perform arm training.
For example, as a conventional example of performing finger recovery training by covering a fist in a gripped state, wearing a glove with an elastic material that reaches the fingertip on the back side of the glove, and repeating the gripping action, grip strength There is something to recover. (For example, refer to Patent Document 1).
