PROBLEM TO BE SOLVED: To provide an elbow injury prevention cover for protecting elbow joints of baseball pitchers.SOLUTION: When throwing a ball with wearing the elbow injury prevention cover, the elbow is not allowed to be stretched sheer straight (180 degrees) at the throwing moment. Since the elbow injury prevention cover has an angle, the elbow is stopped from being stretched 180 degrees despite how sharply the elbow is shaken to throw a ball, which applies no impact to the elbow joint. Not only pitchers, but fielders can receive the protection effect by using the cover. The cover can be used not only in baseball but also in tennis, badminton, etc. Use of the elbow injury prevention cover from childhood wipes out people with elbow injuries from throughout the world.
