< Topic >As it goes up and down automatically, ascent and descent cushioning structure of the automatic watering device which possesses the ascent and descent cushioning effect is offered.SolutionsAscent and descent cushioning structure of the automatic watering device, the inside pipe 10, watering head 20, concatenated sleeve 30, registration component 40, outside pipe has 50 and water supply seat 60. As for the inside pipe 10, joint 11 is formed by one end, male screw section 12 is formed by the place where it is adjacent with joint 11, fixed part 13 is formed to the other end. When watering head 20 is jointed by the joint 11 of the inside pipe 10, the water is supplied, revolving automatically, it waters. Concatenated sleeve 30, through the destal of fixed part 13, fits by the inside pipe 10, the stop ring 31 which with annulation sudden facilities is done to inside concatenated sleeve 30, in inner split is laid out. Female screw section 32 is formed to the aperture which is provided in one end of concatenated sleeve 30. Compressed spring 33 the inside facilities is done, to female screw section 32.< Choice figure >Drawing 2【課題】自動的に昇降するとともに昇降緩衝効果を有する自動散水装置の昇降緩衝構造を提供する。【解決手段】自動散水装置の昇降緩衝構造は、内導管10、散水ヘッド20、連結スリーブ30、位置決め部材40、外導管50及び給水座60を備える。内導管10は、一端に接合部11が形成され、接合部11と隣り合う箇所に雄ねじ部12が形成され、他端に固定部13が形成される。散水ヘッド20は、内導管10の接合部11に接続され、水が供給されると自動的に旋回して散水を行う。連結スリーブ30は、固定部13の端部を介して内導管10に嵌合され、連結スリーブ30の内部には、環状で内方に突設されたストップリング31が配置される。連結スリーブ30の一端に設けられた開口には、雌ねじ部32が形成される。雌ねじ部32には、圧縮バネ33が内設される。【選択図】図2
