< Topic >Raising the contact precision state to the cartridge head underside of the hopper which possesses the outlet of suffering spreading ones, especially, it offers the spreading device which makes the neutron leakage prevention of the medicine establish whose flowability is high with the particulate.SolutionsThe spreading section 1 which possesses delivery roll 1a, it is installed on spreading section and 1 the hopper 2 where the medicine which is suffering spreading ones is stored, being categorized to the cartridge head underside of hopper, 2 being allotted, neutron leakage prevention component 22 of the medicine lying between on cartridge head of hopper 2 of the spreading device which possesses the occulter 4 which opens and closes the outlet 3 of particular cartridge head and with occulters 4 it becomes. As for neutron leakage prevention component 22, Sliding connection unrestricted and the Sliding contact member which is formed and being adhered by the surface side of occulter 4 vis-a-vis the cartridge head underside of hopper, 2 the elastic member which the Sliding contact member with oppression vis-a-vis the cartridge head underside close to airtightness condition it can point it is formed from the layered product.< Choice figure >Drawing 4【課題】被散布物の排出口を有するホッパの底部下面への接触精度・状態を高めて、特に、微粒子で流動性が高い薬剤の漏れ防止を確立させた散布装置を提供する。【解決手段】繰出しロール1aを有する散布部1、散布部1の上に取り付けられ被散布物である薬剤が収容されるホッパ2、ホッパ2の底部下面に位置して配されて当該底部の排出口3を開閉するシャッタ4を有する散布装置のホッパ2の底部とシャッタ4との間に薬剤の漏れ防止部材22を介在してなる。漏れ防止部材22は、ホッパ2の底部下面に対して摺接自在と成す摺接部材と、シャッタ4の上面側に固着されて摺接部材を底部下面に対して弾圧により密閉状に密接させる弾性部材との積層体から形成されている。【選択図】図4
