<P>PROBLEM TO BE SOLVED: To provide a ball net easier to put in and out a ball than a conventional net. <P>SOLUTION: In a relation between a string of a storage part for storing the ball of the ball net, and a grip string 2 engaged with an opening 1 for putting the ball in and out of the storage part and pulled after storing the ball to block the opening, at least two parts which are engaged parts between the opening 1 and the grip string are provided with frictional force applying members α for applying constant frictional forces in the close contact state of the opening 1 and grip string 2. The useless movement of the string is thereby prevented to cause no entanglement. <P>COPYRIGHT: (C)2013,JPO&INPIT |
