PROBLEM TO BE SOLVED: To provide a beach ball which has enough strength to endure irregular movement and an impact which is given when the elderly hit the ball and safety to prevent the elderly from getting injured during play, and is cost effective, and to provide a structure for attaching a string of a beach ball.;SOLUTION: This beach ball 1 is formed by bonding rims of synthetic resin sheets 2 which are made by equally dividing the outer surface of the ball vertically. A circular synthetic resin sheet piece 5 is fixed to their top ends so as to have air-tightness. In the center of the circular synthetic resin sheet piece 5, an air plug 8 is formed as an air inlet. The beach ball 1 has a circular synthetic resin sheet piece 6 adhered onto the circular synthetic resin sheet piece 5, and a doughnut-like synthetic resin sheet piece 7 formed by adhering two or more synthetic resin sheets and placed on the circular synthetic resin sheet piece 6 to surround the air plug 8. The circular synthetic resin sheet piece 6 and synthetic resin sheet piece 7 are adhered to each other at two places which are point-symmetric about the air plug 8.;COPYRIGHT: (C)2012,JPO&INPIT
