PROBLEM TO BE SOLVED: To prevent chemicals from invading into a sliding part in a delivering case in a delivering part of a chemical spreader to improve durability.SOLUTION: The chemical spreader includes a chemical-storing part for storing the chemicals, the delivering part 42 for delivering the chemicals from the chemical-storing part by a prescribed amount, and a spraying part for spraying the chemicals delivered from the delivering part 42. The delivering part 42 is constituted by supporting roll parts 38L and 38R, and roll guides 39L and 39R arranged on both sides thereof on a roll shaft 49 so as to be freely rotatable, and housing them in a delivering case 47. Buffer members 50L and 50R are provided at the sliding parts S and S of the sites at which the roll guides 39L and 39R slidably contact with the delivering case 47.COPYRIGHT: (C)2010,JPO&INPIT【課題】薬剤散布装置の繰出部における繰出ケース内の摺動部への薬剤の侵入を防ぎ、耐久性を向上させる。【解決手段】薬剤を貯溜する薬剤貯留部と、該薬剤貯留部より薬剤を所定量ずつ繰り出す繰出部42と、該繰出部42によって繰り出された薬剤を散布する散布部と、を具備する薬剤散布装置において、前記繰出部42を、ロール部38L・38Rと、その両側に配置するロールガイド39L・39Rとをロール軸49上に回転自在に支持して繰出ケース47内に収納することにより構成し、前記ロールガイド39L・39Rと繰出ケース47とが摺接する部位である摺動部S・Sに緩衝部材50L・50Rを設けた。【選択図】図6
