PROBLEM TO BE SOLVED: To provide an insecticide volatilizing device that is suitable for hanging from a bag, a cart or a proper projection in a house or in a campground.SOLUTION: The insecticide volatilizing device volatilizes insecticidal components at the outside, by rotating a base body that is stored in a device body and is impregnated with the insecticidal components by an electric motor. The insecticide volatilizing device is equipped with a rotatable ring member 30 and a strap 40, that is wound and fixed on the ring member and has a part 40a exposed to the outside of the device body. When the part 40a of the strap exposed to the outside is pulled, the wind is unwound and the length of the strap 40 pulled to the outside of the device is increased. A rotary operating part 32, fixed on the ring member 30, is exposed to the outside of the device and the pulled strap can be wound on the ring member 30 by operating the rotary operation part 32.COPYRIGHT: (C)2009,JPO&INPIT【課題】バッグやカート、あるいは家庭やキャンプ地における適宜の突起物等に吊り下げて使用するのに適した薬剤揮散用器具を提供する。【解決手段】器具本体内に収容した防虫成分を含浸させた基体を電動モータで回転させて防虫成分を外部に揮散させる薬剤揮散用器具。回動自在のリング部材30と、リング部材に巻付け固定されるとともに、一部40aが器具本体外に露出するストラップ40とを備える。外部に露出したストラップの一部40aを引っ張ると、巻きが解けて、ストラップ40の器具本体外への引出し長さが増加する。リング部材30に固定された回動操作部32が器具本体外に露出していて、この回動操作部32を操作することで、引き出されたストラップをリング部材30上に巻き取ることができる。【選択図】図3
