Summary:PROBLEM TO BE SOLVED: To solve frequent troubles of a removal type outdoor tennis post, volleyball post, soccer goal, rugby goal, American football, and ball prevention net that, when elapsing a long period of time after the installation, sands and small stones are flown therein to prevent its removal when the removal is required. SOLUTION: A female taper is provided in the upper end of a buried pipe 5 and a male taper is provided in a required part near the ground of the post 1 for being fitted with the female taper. A clearance between the post 1 and the buried pipe 5 in the lower part of the post 1 is minimized within a range of allowing its insertion and removal. COPYRIGHT: (C)2008,JPO&INPIT
